From a64a6073bd714dce134915a6fa52ee289bf7af20 Mon Sep 17 00:00:00 2001 From: Duc Nguyen Date: Sun, 19 Apr 2026 23:26:13 +0700 Subject: [PATCH 001/148] feat(channels): add zalo_oauth channel skeleton with OAuth v4 paste-code flow Phase 01 of plans/260419-2128-zalo-oa-oauth: introduces a third Zalo transport (phone-number-tied Official Account via OAuth v4) alongside the existing Bot OA and personal QR variants. New package internal/channels/zalo/oauth/ implements the authorization-code exchange against oauth.zaloapp.com; channel lifecycle is a stub until phase 02 wires lazy refresh and phase 03 wires Send. Also fixes a pre-existing bug where WS-side isValidChannelType was missing facebook + pancake (HTTP side already had them).

23:44:43 +0700 Subject: [PATCH 002/148] feat(channels/zalo_oauth): lazy token refresh with single-flight + safety ticker MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Phase 02 of plans/260419-2128-zalo-oa-oauth: adds the lazy-refresh token source mirroring DBTokenSource (single mutex serializes both cache reads and HTTP refresh — Zalo refresh tokens are single-use, so racing goroutines must not be allowed to issue concurrent refreshes). Adds a 30-min safety ticker so idle channels still keep their tokens alive between Sends. Loader now injects channel_instances.id via duck-typed SetInstanceID, reusing the same pattern as SetTenantID — needed by the refresh path to persist rotated credentials back to the same row.

Text goes straight to /oa/message/cs; image/file follow Zalo's 2-step upload-then-attach pattern with the upload `token` referenced in the message attachment payload. The send wrapper retries exactly once on auth-class API errors after calling tokens.ForceRefresh, so a token rotated externally between Send calls recovers transparently without an infinite loop. Caption + Content alongside an attachment ride as a separate trailing text message; if that trailing send fails after the attachment was delivered, returns ErrPartialSend so callers can distinguish from a full failure.

charset=UTF-8 Content-Transfer-Encoding: 8bit Phase 04 of plans/260419-2128-zalo-oa-oauth: implements the inbound path. A 15s ticker fans out to /v3.0/oa/listrecentchat then per-thread /conversation, deduplicates against an in-memory pollCursor (LRU at 500 entries), and publishes new messages via BaseChannel.HandleMessage with peerKind="direct" — Zalo OA has no groups. Cursor is debounced-persisted (60s) into channel_instances.config under a poll_cursor key, surviving channel restarts without replaying old messages. Loader-side instance ID injection (added in phase 02) is what makes the persistence path actually addressable. Top-K fan-out cap (20 threads/cycle) keeps the API request budget bounded under high-volume OAs. HTTP 429 trips a 30s backoff via ticker.Reset and flips channel health to Degraded; the next clean cycle restores Healthy and the original interval. Halt-on-reauth guard skips the API entirely when health is Failed/Auth so we don't hammer a dead token.

charset=UTF-8 Content-Transfer-Encoding: 8bit Phase 06 of plans/260419-2128-zalo-oa-oauth: data-driven schema entries for zalo_oauth credentials + config (rendered automatically by the existing ChannelFields component) plus a new paste-code dialog that drives the two-step OAuth flow: 1. Calls channels.instances.zalo_oauth.consent_url to fetch the pre-built Zalo authorization URL (server-side keeps app_id out of the masked instance payload). 2. User opens the URL, approves on Zalo, copies the redirect's `code` query param, pastes it back, and the dialog calls channels.instances.zalo_oauth.exchange_code which validates the CSRF state token and persists the rotated credentials. Registered as a reauthDialog so the row-level Connect / Re-auth button is wired by the existing channel-table machinery — no new button code in the page itself. Strings are English literals with TODO i18n markers; phase 07 wires translations.

From e0e99c04612eb1da086967c8fc30f573f2c206fe Mon Sep 17 00:00:00 2001 From: Duc Nguyen Date: Mon, 20 Apr 2026 01:20:42 +0700 Subject: [PATCH 008/148] test(channels/zalo_oauth): integration lifecycle + gap-fill unit tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Phase 08 of plans/260419-2128-zalo-oa-oauth: most unit tests already shipped via TDD across phases 01-06. Fills 2 gaps: - TestForceRefresh_ClearsCache: verifies tokenSource.ForceRefresh zero-time math triggers refresh on next Access. - TestPollOnce_AllowlistBlocksNonAllowedSender: proves the inbound path goes through BaseChannel.HandleMessage's allowlist check, not direct bus.Publish (phase-04 audit C1 verification). Adds tests/integration/zalo_oauth_lifecycle_test.go covering the full feature against real Postgres + a mocked Zalo API: row create → store-encrypts → Get round-trip → factory + Start → SendText → ForceRefresh + send → invalid_grant → health flips Failed/Auth → Stop bounded. Two test-only methods (SetTestEndpointsForTest / ForceRefreshForTest) are named with the *ForTest suffix per Go convention so accidental production usage is grep-visible. Also wires zalo_oauth into ui/web/src/constants/channels.ts so the Add Channel dropdown actually shows the option — the dropdown is hard-coded there, not derived from credentialsSchema keys. The existing zalo_oa entry is relabeled "Zalo OA (Bot)" to disambiguate the two channel types in the UI.

The hardcoded placeholder shipped in phase 06 will never satisfy that check, so any operator who didn't pre-register https://oa.local/zalo_oauth_callback (i.e. everyone) was blocked at the consent screen. Adds redirect_uri to ChannelCreds + the credentials wizard schema as a required text field. The consent_url WS handler now reads it from creds with the old hardcoded URL as a fallback (so existing rows without the field don't break, even though they'll still hit the -14003 error until the operator fills it in).

Users expect the same flow as whatsapp / zalo_personal where Create transitions directly into the authentication step of the wizard. Splits the paste-code state machine into a shared hook (use-zalo-oauth-connect) + a shared view (zalo-oauth-connect-body), so both entry points (wizardAuthSteps + reauthDialogs) reuse the same logic and can diverge only in their action-button layout. wizardConfig.zalo_oauth.steps = ["auth"] wires the transition; the reauth dialog is unchanged for operators who dismiss the wizard and want to complete authentication later from the row.

Zalo's live OAuth endpoint returns expires_in as a quoted string ("3600"), not a number. This broke the exchange with a JSON unmarshal error. Introduces a flexSeconds type whose custom UnmarshalJSON strips surrounding quotes before ParseInt, so both shapes decode correctly. TestTokenResponseShape gains a second assertion for the string form. 2. Zalo redirects to the operator's callback with a long URL of the form https://example.com/zalo-callback?oa_id=...&code=iYP... &state=db8... — operators shouldn't have to extract code by hand. Adds an extractCode helper that accepts either a raw code or the full URL; when a URL is pasted, we pull out the code param and opportunistically compare the URL's state to the one we stashed from consent_url.

Two root causes, fixed together because they rhyme: 1. The phase-04 plan assumed listrecentchat/getconversation lived at /v3.0/oa/* per the ChickenAI SDK note that "v2.0 is discontinued". Live Zalo OA disagrees — those read endpoints remain on /v2.0/* (nh4ttruong/zalo-oa-api-wrapper confirms). Paths moved to /v2.0/oa/getlistrecentchat and /v2.0/oa/getconversation with the v2.0 convention of packing GET params into ?data={json}. 2. access_token was riding as a URL query param; Zalo OA's OpenAPI expects it in an `access_token` header. Query-form token gets the 404 "empty or invalid API" response. Moved to the header everywhere (apiGet, apiPost, apiPostMultipart). Side benefit: the token no longer appears in any URL, eliminating the phase-03 L4 concern about *url.Error leaking the token through DNS/TLS errors. Send (/v3.0/oa/message/cs) and upload (/v2.0/oa/upload/*) paths are unchanged — those already matched the wrapper.

charset=UTF-8 Content-Transfer-Encoding: 8bit The phase-04 plan said `listrecentchat` / `conversation` live at `/v3.0/*`, and my first post-smoke fix flipped to `/v2.0/*` AND added a `get` prefix (as nh4ttruong/zalo-oa-api-wrapper uses for `user/getlist`). Both guesses were wrong. Empirically probed all four variants against live Zalo — unprefixed v2.0 paths return `error:-216 Access token is invalid` (endpoint exists, just wants a valid token) while the other three return the generic `error:404` endpoint-not-found response. So the correct paths are: GET /v2.0/oa/listrecentchat?data={json} GET /v2.0/oa/conversation?data={json} No get prefix. Send (/v3.0/oa/message/cs) and upload (/v2.0/oa/upload/*) paths remain unchanged — those match the wrapper.

Channel.post already does a retry- once-on-auth via ForceRefresh; poll now mirrors the same pattern for the listRecentChat call. Zalo's documented token lifetime is 24h but operators have seen the token rejected well inside that window (likely revoked app-side on certain operations). Refresh-on-reject keeps the channel alive without waiting for the 30min safety ticker to catch up. If the second attempt also auth-fails, the existing downstream path (ErrAuthExpired → markAuthFailedIfNeeded) flips health to Failed/Auth so the operator sees a clear re-auth prompt instead of silent looping.

The `message` Go struct read the text field as "text" — Zalo's actual field name is "message". Every inbound was silently dropped at the `if m.Text == ""` guard in dispatchInbound, even when the HTTP call succeeded. 2. Modeled as "threads → per-thread getconversation fan-out", but listrecentchat already returns messages. getConversation + thread type + topKThreads cap are all dead. Simplified pollOnce to iterate messages directly, filter OA echoes (from_id == oa_id), dedup per- user by time. Also: - Added display-name passthrough in metadata.sender_display_name. - DM chatID derives from from_id (Zalo OA is DM-only). - Removed /v2.0/oa/conversation test routing and per-thread call tracking. - Removed TestPollOnce_TopKThreadsCap (concept no longer applies).

Pipeline: 1. Decode input bytes (png / jpeg / webp). 2. Resize progressively (longest side 1600 → 1200 → 900 → 600). 3. At each size, JPEG-encode with quality ladder 85 → 35. 4. Return the first encoding that fits under the cap. 5. Fail loudly with original + compressed dims if even the lowest quality at the smallest size exceeds the cap. Channel.Send routes by MIME before upload: - image/gif → SendGIF (new) → /upload/gif - image/* → compressForZaloImage + SendImage → /upload/image - PDF/DOC/DOCX → SendFile → /upload/file (size pre-check at 5MB) - anything else → reject at the dispatcher Also tightens the stat-first check to 50MB (absolute OOM guard) so compression gets a chance to run on mid-sized files. Operators who set cfg.MediaMaxMB still see it honored on the file path — images always compress-to-fit. Adds github.com/disintegration/imaging + golang.org/x/image/webp for the compression pipeline (already pulled in via agent/media_sanitize). Three new unit tests cover the compressor's passthrough, shrink-over- cap, and decode-error paths.

Also: parseUploadToken now embeds a 500-char prefix of the raw response in its error when data.token is missing, so the next-time triage sees what Zalo actually returned instead of the generic "missing data.token".

The real wire name is `attachment_id`, which is why uploads succeeded (HTTP 200 + error=0) but our parser returned "missing data.token" and the send never happened. Fix threads the correct name through: - parseUploadToken renamed to parseUploadAttachmentID. Primary field is `attachment_id`; keep `token` as a legacy fallback for defensive forward-compat if Zalo ever adds an alias. - SendImage, SendFile, SendGIF outbound payloads now carry `{"attachment_id": id}` instead of `{"token": id}` — matches what the upload endpoint returned and what Zalo's own send endpoint almost certainly expects.

Confirmed against the nh4ttruong/zalo-oa-api-wrapper Python reference and the esms.vn integration docs: /v3.0/oa/message/cs wants the template/media shape for uploaded media: { "recipient": {"user_id": "..."}, "message": { "attachment": { "type": "template", "payload": { "template_type": "media", "elements": [{ "media_type": "image", // or "gif" "attachment_id": "" // or "url" for URL-based }] } } } } Extracted the common construction into buildMediaAttachmentBody so image + gif reuse the shape. SendFile stays on its original simple form {"type":"file","payload":{"attachment_id":"..."}} — that's what the file endpoint wants (template/media is image-only). Test assertions updated to walk the template→payload→elements→ media_type/attachment_id path.

consume msg.Media[] MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace fragile [photo:URL] substring parser with typed bus.OutboundMessage.Media[] consumption (mirrors zalo/oa). Bot API only supports remote URLs (no upload), so local-path media is rejected with a clear error directing operators to the zalo_oa channel. Caption + content merged via mergeTrailingText helper (cf. oa/channel.go:243). Multiple-media inputs use the first attachment; extras are logged and skipped. A sync.Once-gated slog.Warn fires once-per-process if any unmigrated caller still emits the deprecated [photo:URL] sentinel — defense in depth even after the repo-wide grep cleanup. Tests rewritten: empty Media → text path, http URL → sendPhoto with merged caption, local path → rejection with no API call. --- internal/channels/zalo/bot/channel.go | 61 ++++++++++++++++++----- internal/channels/zalo/bot/zalo_test.go | 65 +++++++++++++++++++++++-- 2 files changed, 110 insertions(+), 16 deletions(-) diff --git a/internal/channels/zalo/bot/channel.go b/internal/channels/zalo/bot/channel.go index 8794aa3cf4..aa8ced4e51 100644 --- a/internal/channels/zalo/bot/channel.go +++ b/internal/channels/zalo/bot/channel.go @@ -12,6 +12,7 @@ import ( "log/slog" "net/http" "strings" + "sync" "time" "github.com/nextlevelbuilder/goclaw/internal/bus" @@ -37,6 +38,10 @@ type Channel struct { client *http.Client pollClient *http.Client // pairingService, pairingDebounce are inherited from channels.BaseChannel. + + // legacyPhotoSentinelWarn fires once-per-process if any caller still + // emits the deprecated [photo:URL] sentinel after the Media[] migration. + legacyPhotoSentinelWarn sync.Once } // New creates a new Zalo channel. @@ -110,20 +115,52 @@ func (c *Channel) Send(_ context.Context, msg bus.OutboundMessage) error { // Strip markdown — Zalo does not support any markup rendering. msg.Content = StripMarkdown(msg.Content) - // Check for media in content (URL-based photo sending) + // Defensive: warn if any caller still emits the legacy [photo:URL] sentinel + // after the migration.

Per-channel HTTP clients, send pipelines, and auth stay separate. Contents: - webhook_router.go: single-mount Router with multi-instance dispatch by ?instance=. 405/400/429/404/401/200 status codes; rate-limit and signature checks before dispatch; LRU+TTL dedup short-circuit; panic recovery via internal/safego.Recover. Tests construct their own router (no process-wide singleton) and run race-detector clean. - dedup.go: bounded LRU+TTL cache keyed (instanceID|messageID). Polling stays on oa/seen_ids.go — no cross-path migration. - inbound.go: InboundMeta + ToMap helper unifying the metadata map both channels publish to the bus. Constants PlatformZaloBot/PlatformZaloOA. - markdown.go: StripMarkdown moved from bot/format.go. bot/format.go is now a thin re-export to keep zalo/personal compiling. Wiring: - gatewayDeps gains a *zalocommon.Router. cmd/gateway.go constructs it alongside channelMgr; cmd/gateway_lifecycle.go mounts it once at /channels/zalo/webhook. Channels never return a path string — per-instance Register/Unregister calls land in phases 04 + 05. - bot.FactoryWithRouter and oa.FactoryWithRouter accept the router and store it on the Channel struct (legacy Factory entries retained for the config-only single-tenant path). Behavior change: - Bot inbound metadata platform "zalo" -> "zalo_bot" (S1 in plan). Repo-grep audit found no consumers keyed on the old literal value.

Polling remains the default. Webhook flow: - Zalo POSTs to /channels/zalo/webhook?instance= - Shared common.Router validates rate limit + signature + dedup - Bot's HandleWebhookEvent decodes the same getUpdates-shaped payload the polling path consumes; existing processUpdate / handleTextMessage / handleImageMessage are reused without duplication. Channel.Start branches on transport. Webhook path: - Requires webhook_secret (B6 explicit empty-secret reject — without this guard, crypto/subtle.ConstantTimeCompare("","") returns 1 and every request would pass). - Requires the FactoryWithRouter wiring (otherwise router pointer is nil). - Captures botID from getMe — used by the A8 self-echo filter to drop events Zalo echoes back from our own outbound sends, preventing the bot from replying to itself in a loop. - Calls router.RegisterInstance(c.instanceID, c, c.TenantID()). Channel.Stop unregisters from the router so subsequent requests return 404 cleanly instead of dispatching to a stopped channel. Signature verification uses a header-token compare with constant-time match (crypto/subtle.ConstantTimeCompare). Mismatch returns common.ErrSignatureMismatch which the router maps to 401 + structured log "security.zalo_webhook_signature_mismatch". ZaloOAConfig also gains Transport / WebhookSignatureMode / WebhookReplayWindowSeconds / CatchUpOnRestart fields here so the config type changes ship together; phase 05 consumes them.

Modes strict/log_only/disabled (B5) with normalizeMode("") -> strict (N6). Replay window default 300s, clamp [60, 3600] (B7). Self-echo filter on Sender.ID == creds.OAID (A8). Catch-up sweep (B4): single bounded listrecentchat page on Start when cursor stale >30min, runs in goroutine tracked by catchUpWG with stopCh-driven ctx cancel (N2). Belt-and-suspenders gate in runPollLoop early-returns when transport=webhook. Router improvements landing alongside (Round-3 patches): - R3-2: per-instance empty-id streak counter; warn at N=10 then reset. - R3-3: per-instance ctx + cancel on UnregisterInstance so Stop drains in-flight HandleWebhookEvent within 100ms. Adds cfg.WebhookOASecretKey distinct from creds.SecretKey (S7). Adds pollCursor.LastSeenTimestamp() for the staleness gate. Tests cover fixed-fixture sig, length precondition, all three modes, replay window, self-echo, catch-up gating, and S7 wiring. --- .../channels/zalo/common/webhook_router.go | 72 ++- .../zalo/common/webhook_router_test.go | 150 ++++++ internal/channels/zalo/oa/catchup.go | 64 +++ internal/channels/zalo/oa/catchup_test.go | 157 +++++++ internal/channels/zalo/oa/channel.go | 60 ++- internal/channels/zalo/oa/poll_cursor.go | 15 + internal/channels/zalo/oa/poll_cursor_test.go | 29 ++ internal/channels/zalo/oa/poll_loop.go | 8 + internal/channels/zalo/oa/webhook.go | 122 +++++ .../channels/zalo/oa/webhook_signature.go | 187 ++++++++ internal/channels/zalo/oa/webhook_test.go | 443 ++++++++++++++++++ .../channels/zalo/oa/webhook_transport.go | 64 +++ internal/config/config_channels.go | 1 + 13 files changed, 1344 insertions(+), 28 deletions(-) create mode 100644 internal/channels/zalo/oa/catchup.go create mode 100644 internal/channels/zalo/oa/catchup_test.go create mode 100644 internal/channels/zalo/oa/webhook.go create mode 100644 internal/channels/zalo/oa/webhook_signature.go create mode 100644 internal/channels/zalo/oa/webhook_test.go create mode 100644 internal/channels/zalo/oa/webhook_transport.go diff --git a/internal/channels/zalo/common/webhook_router.go b/internal/channels/zalo/common/webhook_router.go index 059f98aba6..8df3c5957f 100644 --- a/internal/channels/zalo/common/webhook_router.go +++ b/internal/channels/zalo/common/webhook_router.go @@ -8,6 +8,7 @@ import ( "log/slog" "net/http" "sync" + "sync/atomic" "time" "github.com/google/uuid" @@ -25,15 +26,31 @@ import ( // path; we want a single-mount, multi-instance router. type Router struct { mu sync.RWMutex - instances map[uuid.UUID]registeredInstance + instances map[uuid.UUID]*registeredInstance dedup *Dedup rateLimiter *channels.WebhookRateLimiter maxBodySize int64 } +// emptyIDStreakWarnThreshold is the consecutive count of empty +// ExtractMessageID() returns that triggers a single warn-level log.

Burn-down terminates on partial page or maxPages cap; the cap emits zalo_oa.poll.burndown_capped warn. Default ceiling rises from ~10 msg/cycle to ~250 msg/cycle (~25x headroom) for bursty OAs without changing single-page semantics. Single-cycle dedup intact across multi-page via existing cursor (per-from_id last-seen time) + seen_ids LRU fallback.

Operator prepends their gateway's externally- reachable URL — no fabricated PublicBaseURL config (B3). Works for both zalo_bot and zalo_oa instances. Cross-tenant lookup returns NotFound (defense-in-depth, mirrors zalo_oa.go:80). Validation: - Invalid UUID → ErrInvalidRequest - Unknown / cross-tenant instance → ErrNotFound (single shape; no instance-existence probe across tenants) - Wrong channel type → ErrInvalidRequest - Valid bot/oa → {path: /channels/zalo/webhook?instance=, ...} Adds gateway.NewCapturingTestClient helper so out-of-package handler tests can capture response frames without a real WS conn. UI: ZaloWebhookURLSection rendered in the General tab for zalo_bot/ zalo_oa instances — read-only path field with copy button + operator hint to prepend their public host. i18n triplet (en/vi/zh) for both backend hint string and frontend labels. --- cmd/gateway_channels_setup.go | 1 + internal/gateway/client_testing.go | 17 ++ internal/gateway/methods/zalo_webhook.go | 70 ++++++ internal/gateway/methods/zalo_webhook_test.go | 199 ++++++++++++++++++ internal/i18n/catalog_en.go | 4 + internal/i18n/catalog_vi.go | 4 + internal/i18n/catalog_zh.go | 4 + internal/i18n/keys.go | 4 + pkg/protocol/methods.go | 4 + ui/web/src/i18n/locales/en/channels.json | 6 + ui/web/src/i18n/locales/vi/channels.json | 6 + ui/web/src/i18n/locales/zh/channels.json | 6 + .../channel-detail/channel-general-tab.tsx | 9 + .../zalo/zalo-webhook-url-section.tsx | 89 ++++++++ 14 files changed, 423 insertions(+) create mode 100644 internal/gateway/methods/zalo_webhook.go create mode 100644 internal/gateway/methods/zalo_webhook_test.go create mode 100644 ui/web/src/pages/channels/zalo/zalo-webhook-url-section.tsx diff --git a/cmd/gateway_channels_setup.go b/cmd/gateway_channels_setup.go index 4a0d1611ab..5aec813840 100644 --- a/cmd/gateway_channels_setup.go +++ b/cmd/gateway_channels_setup.go @@ -153,6 +153,7 @@ func wireChannelRPCMethods(server *gateway.Server, pgStores *store.Stores, chann if pgStores.ChannelInstances != nil { methods.NewChannelInstancesMethods(pgStores.ChannelInstances, pgStores.Agents, msgBus, msgBus).Register(server.Router()) methods.NewZaloOAMethods(pgStores.ChannelInstances, msgBus).Register(server.Router()) + methods.NewZaloWebhookMethods(pgStores.ChannelInstances).Register(server.Router()) zalomethods.NewQRMethods(pgStores.ChannelInstances, msgBus).Register(server.Router()) zalomethods.NewContactsMethods(pgStores.ChannelInstances).Register(server.Router()) whatsapp.NewQRMethods(pgStores.ChannelInstances, channelMgr).Register(server.Router()) diff --git a/internal/gateway/client_testing.go b/internal/gateway/client_testing.go index b7bb400f6a..d6ce587fe7 100644 --- a/internal/gateway/client_testing.go +++ b/internal/gateway/client_testing.go @@ -21,3 +21,20 @@ func NewTestClient(role permissions.Role, tenantID uuid.UUID, userID string) *Cl tenantID: tenantID, } } + +// NewCapturingTestClient is like NewTestClient but also returns a buffered +// send channel so response/event frames can be inspected by the test.

Webhook mounting flows through the generic Manager.WebhookHandlers() iteration in gateway_lifecycle, restoring the channel-plane abstraction. Squash with phase 4 to keep the cmd/ build green per-commit (FactoryWithRouter deletion alone leaves cmd/gateway.go broken). Drops the dead `c.webhookRouter == nil` guard in oa/webhook_transport.go (singleton guarantees non-nil) and routes gateway/methods/zalo_webhook.go through common.WebhookPath const for DRY.

Remove the shim, point both call sites (bot/channel.go, personal/send.go) at common.StripMarkdown directly, and merge bot/format_test.go's richer cases into common/markdown_test.go.

Events notice: new ZaloOAEventsNotice component (collapsible amber notice) lists events to enable in Zalo console. Integrated into channel instance form step after ChannelScopesInfo. Auth help: added authorizeHelp paragraph under Step 1 in ZaloOAConnectBody with operator instructions. i18n: removed orphan webhookSecretRequired error key.

Both zalo_bot and zalo_oa now use MountRoute(router) during bootstrap to register slug on startup + attach signature verifier middleware. Added slug.go utility: deriveSlug() normalizes phone/OA-ID to URL-safe slug. Slug stored in creds, retrieved from config during bootstrap. Test coverage: slug derivation + dedup. Config channel schema: added Transport field (polling/webhook) + ZaloOAConfig for app_id/ redirect_uri/oa_id/phone (unified under zalo_oa type). Gateway lifecycle: BootstrapChannels now calls MountRoute for all channels supporting webhook transport. Webhook handler (zalo_webhook.go) dispatches based on slug lookup from slug store. No behavior change for existing deployments; bot/OA webhook setup now idempotent (safe reload). --- cmd/gateway_lifecycle.go | 14 ++ internal/channels/zalo/bot/channel.go | 26 ++- internal/channels/zalo/bot/factory.go | 14 +- internal/channels/zalo/common/shared.go | 11 +- internal/channels/zalo/common/shared_test.go | 8 +- internal/channels/zalo/common/slug.go | 62 ++++++ internal/channels/zalo/common/slug_test.go | 89 +++++++++ .../channels/zalo/common/webhook_router.go | 97 +++++++--- .../zalo/common/webhook_router_test.go | 178 +++++++++++++----- internal/config/config_channels.go | 7 +- internal/gateway/methods/zalo_webhook.go | 33 +++- internal/gateway/methods/zalo_webhook_test.go | 35 +++- 12 files changed, 466 insertions(+), 108 deletions(-) create mode 100644 internal/channels/zalo/common/slug.go create mode 100644 internal/channels/zalo/common/slug_test.go diff --git a/cmd/gateway_lifecycle.go b/cmd/gateway_lifecycle.go index bc6c4277b0..73c4e835ae 100644 --- a/cmd/gateway_lifecycle.go +++ b/cmd/gateway_lifecycle.go @@ -3,6 +3,7 @@ package cmd import ( "context" "log/slog" + "net/http" "os" "strings" "time" @@ -10,6 +11,7 @@ import ( "github.com/nextlevelbuilder/goclaw/internal/bus" "github.com/nextlevelbuilder/goclaw/internal/cache" "github.com/nextlevelbuilder/goclaw/internal/channels" + zalocommon "github.com/nextlevelbuilder/goclaw/internal/channels/zalo/common" "github.com/nextlevelbuilder/goclaw/internal/config" "github.com/nextlevelbuilder/goclaw/internal/edition" "github.com/nextlevelbuilder/goclaw/internal/heartbeat" @@ -207,9 +209,21 @@ func (d *gatewayDeps) runLifecycle( // Mount channel webhook handlers on the main mux (e.g. Feishu /feishu/events). // This allows webhook-based channels to share the main server port. + zaloPrefixMounted := false for _, route := range d.channelMgr.WebhookHandlers() { mux.Handle(route.Path, route.Handler) slog.Info("webhook route mounted on gateway", "path", route.Path) + if route.Path == zalocommon.WebhookPathPrefix { + zaloPrefixMounted = true + } + } + // Suppress http.ServeMux 301 redirect from bare /channels/zalo/webhook to + // /channels/zalo/webhook/.

Integration tests run in temporary schema with real DB; bootstrap idempotency now guaranteed. --- tests/integration/zalo_reload_safety_test.go | 23 +++++--- .../zalo_webhook_integration_test.go | 52 ++++++++++++------- 2 files changed, 49 insertions(+), 26 deletions(-) diff --git a/tests/integration/zalo_reload_safety_test.go b/tests/integration/zalo_reload_safety_test.go index a5cc040905..2f62125bb5 100644 --- a/tests/integration/zalo_reload_safety_test.go +++ b/tests/integration/zalo_reload_safety_test.go @@ -29,15 +29,17 @@ import ( // MountRoute call must return ("", nil). func TestZaloWebhook_MountRouteIdempotentAcrossReload(t *testing.T) { router := common.NewRouter() - srv := httptest.NewServer(router) + mux := http.NewServeMux() + mux.Handle(common.WebhookPathPrefix, router) + srv := httptest.NewServer(mux) t.Cleanup(srv.Close) msgBus := bus.New() // First MountRoute — must claim the path. path1, h1 := router.MountRoute() - if path1 != common.WebhookPath || h1 != router { - t.Fatalf("first MountRoute = (%q, %v), want (%q, router)", path1, h1, common.WebhookPath) + if path1 != common.WebhookPathPrefix || h1 != router { + t.Fatalf("first MountRoute = (%q, %v), want (%q, router)", path1, h1, common.WebhookPathPrefix) } // Register an OA instance, send a signed event, drain inbound — proves @@ -48,10 +50,10 @@ func TestZaloWebhook_MountRouteIdempotentAcrossReload(t *testing.T) { creds := &oa.ChannelCreds{ AppID: "oa-app", SecretKey: "oa-sk", OAID: "oa-mt", AccessToken: "AT", RefreshToken: "RT", ExpiresAt: time.Now().Add(time.Hour), + WebhookSecretKey: secret, } cfg := config.ZaloOAConfig{ Transport: "webhook", - WebhookOASecretKey: secret, WebhookSignatureMode: "strict", WebhookReplayWindowSeconds: 300, } @@ -61,10 +63,13 @@ func TestZaloWebhook_MountRouteIdempotentAcrossReload(t *testing.T) { } ch.SetInstanceID(instID) ch.SetTenantID(tenantID) - router.RegisterInstance(instID, ch, tenantID) + const slug = "oa-reload" + if err := router.RegisterInstance(instID, ch, tenantID, slug); err != nil { + t.Fatalf("RegisterInstance: %v", err) + } body, sig := buildSignedOAEvent(t, "oa-app", "oa-mt", "user-r1", "before-reload", secret) - resp, err := postWebhook(t, srv.URL, instID, http.Header{ + resp, err := postWebhook(t, srv.URL, slug, http.Header{ "X-Zevent-Signature": []string{sig}, "Content-Type": []string{"application/json"}, }, body) @@ -96,12 +101,14 @@ func TestZaloWebhook_MountRouteIdempotentAcrossReload(t *testing.T) { } ch2.SetInstanceID(instID) ch2.SetTenantID(tenantID) - router.RegisterInstance(instID, ch2, tenantID) + if err := router.RegisterInstance(instID, ch2, tenantID, slug); err != nil { + t.Fatalf("RegisterInstance (post-reload): %v", err) + } t.Cleanup(func() { router.UnregisterInstance(instID) }) // Dispatch through the same route still works post-reload. body2, sig2 := buildSignedOAEvent(t, "oa-app", "oa-mt", "user-r2", "after-reload", secret) - resp, err = postWebhook(t, srv.URL, instID, http.Header{ + resp, err = postWebhook(t, srv.URL, slug, http.Header{ "X-Zevent-Signature": []string{sig2}, "Content-Type": []string{"application/json"}, }, body2) diff --git a/tests/integration/zalo_webhook_integration_test.go b/tests/integration/zalo_webhook_integration_test.go index 2ee87adbd2..f3b1e7494f 100644 --- a/tests/integration/zalo_webhook_integration_test.go +++ b/tests/integration/zalo_webhook_integration_test.go @@ -79,7 +79,9 @@ func drainOneInbound(t *testing.T, msgBus *bus.MessageBus, budget time.Duration) // 3.

Bot has no UI MarkFailed-by-family routing, so no Family enum is needed there. - i18n: 11 new `MsgZaloOAErr*` keys with en/vi/zh translations. - Docs: `docs/zalo-error-codes.md` is the scraper output (Social API + bot-api sections); regenerable via `scripts/fetch-zalo-error-codes.cjs`. - Tests: table-driven coverage in `errors_test.go` for both packages.

Zalo OA silently retries without quote on `FamilyPayload` errors (expired/deleted source).
 - **i18n:** Web UI uses `i18next` with namespace-split locale files in `ui/web/src/i18n/locales/{lang}/`. Backend uses `internal/i18n` message catalog with `i18n.T(locale, key, args...)`. Locale propagated via `store.WithLocale(ctx)` — WS `connect` param `locale`, HTTP `Accept-Language` header. Supported: en (default), vi, zh. New user-facing strings: add key to `internal/i18n/keys.go`, add translations to all 3 catalog files. New UI strings: add key to all 3 locale dirs. Bootstrap templates (SOUL.md, etc.) stay English-only (LLM consumption).

Subject: [PATCH 087/148] fix(channels/zalo): address PR review findings (token
 leak, dispatch race, markdown, dedup)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- bot: scrub token from transport errors so *url.Error doesn't leak it to logs
- common: per-instance dispatchWG drains in-flight handlers on Unregister
- common: dedup gets per-instance cap and injectable clock
- common: __dunder__ identifiers preserved through StripMarkdown
- oa: clone Media slice before stripping captions so caller's data stays intact
- oa: catchup-sweep inner watcher tracked under catchUpWG
- oa: relax inbound attachment ext heuristic (no allow-list — accept any reasonable ext)
- tests: PG round-trip test for migration 000058
- tests: fix pre-existing SendText signature break in zalo_oa_lifecycle_test

Subject: [PATCH 088/148] chore(tests): drop PG round-trip test for migration
 000058

The migration is a 3-statement sentinel-swap rename already shipped to
production; a dedicated PG round-trip test is gold-plating without a

From dc8068a4b6d6a49e22f8751845bdafe30e6bb8eb Mon Sep 17 00:00:00 2001
From: Duc Nguyen 
Date: Fri, 1 May 2026 00:57:50 +0700
Subject: [PATCH 089/148] feat(channels/zalo-oa): surface re-consent warning
 before refresh-token expiry
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Parse refresh_token_expires_in from Zalo OAuth response, persist alongside
existing creds, and transition channel health Healthy↔Degraded(retryable
auth) when the deadline drops within a 14-day window. Adds i18n key
MsgZaloOAReauthDueSoon and a UI tooltip on the channel-list row so
operators can re-consent before silent failure.

Subject: [PATCH 090/148] feat(channels/zalo-oa): outbound status emoji
 reactions on user messages (#966)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Implement channels.ReactionChannel for zalo_oa. Agent run state surfaces
as a Zalo emoji on the user's inbound message: thumbs-up "received,
working" debounced through 700ms, then heart on done or sad on error.
Default reaction_level=off; minimal sends only terminal pair (≤2/run);
full adds the thumbs-up ack. tool/coding/web mid-flight statuses are
intentionally NOT mapped — they look unprofessional in B2C customer
chats and burn the 50-per-message-id cap. Endpoint POST /v2.0/oa/message
with sender_action.{react_icon, react_message_id}; /-remove sentinel
retracts. SendReaction bypasses c.post so reaction errors never flip
channel health.

 - If the source message is older than Zalo's 48h interaction window or has been deleted, the gateway transparently retries without the quote field — the reply is still delivered, with a `zalo_oa.send.quote_dropped_payload_error` warning logged for diagnostics.
 
-## 6. Reference
+## 6. Reactions (status emoji on user messages)
+
+Set `reaction_level` in the channel config to surface agent run progress as a Zalo reaction on the user's inbound message. The defaults are tuned for the B2C / customer-service surface that real OAs run — quiet by default, conservative when on:
+
+- `off` (**default**) — no reactions sent. Existing tenants stay silent on upgrade.
+- `minimal` (**recommended for production**) — terminal-only: `/-heart` on success, `:-((` on failure. Exactly 0–2 reactions per agent run; doesn't pollute the customer's chat with mid-flight noise.
+- `full` — adds a single "received, working on it" `--b` (thumbs-up) on the first intermediate event, debounced to ≤1 call per 700 ms. Mid-run tool/coding/web statuses are intentionally NOT mapped on Zalo OA — chatty intermediate reactions on a customer support conversation feel unprofessional and eat into the 50-reaction-per-`message_id` cap. If you need the full Telegram-style transition set, extend `statusReactionVariants` in `internal/channels/zalo/oa/reactions.go`.
+
+Zalo OA caps reactions at 50 per source `message_id`. The endpoint (`POST /v2.0/oa/message`) does NOT count against the OA monthly active-message quota. Reactions are best-effort: failures are logged at Debug and never flip channel health. `ClearReaction` sends the `/-remove` sentinel to retract a previously dropped reaction (Zalo has no separate clear endpoint).

Subject: [PATCH 091/148] fix(channels/zalo-oa): restore reactions field +
 reauth warning lost in merge

Restore Channel.reactions sync.Map field + ReactionChannel interface assertion
+ Stop() debounce cleanup that were lost in 71002c5e merge. Also restore Phase 2
reauth warning: reauthWarningWindow constant, evaluateReauthWarning() helper,
else clause in runSafetyTicker. Package now compiles; proactive warning ships
as designed. Fixes GH-966.

 tighten signature/auth handling
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Address review points: (1) router ServeHTTP releases lock before dispatchWG.Add → race with UnregisterInstance Wait; reserveDispatchSlot() now does lookup+Add atomically under RLock. (2) RegisterInstance rejects uuid.Nil to prevent silent overwrite of in-memory instance. (3) classifyRefreshError drops substring fallback that misclassified localized server messages as ErrAuthExpired. (4) log_only signature mismatch no longer logs HMAC prefix.

Subject: [PATCH 113/148] fix(ui/channels): re-seed config defaults on
 channel-type switch in create dialog

In create mode the form mounts with telegram defaults; switching to
zalo_bot left configValues stale, so webhook_secret's
showWhen={transport:webhook} never matched and the field (with the
Generate button) stayed hidden. Watch channelType and re-apply the
target schema's defaults.

Subject: [PATCH 114/148] refactor(channels/zalo-oa): harden image compression
 for orientation and transparency
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Decode via imaging.AutoOrientation so EXIF-rotated phone photos arrive upright after re-encode
- Rewrite hasTransparency with type-switch on Pix/Palette buffers — exhaustive (no sample-based false negatives) and skips work for image/jpeg
- Add white-flatten JPEG fallback when transparent PNG can't fit byte cap, instead of hard-failing
- Split inline ladder loops into encodePNGLadder / encodeJPEGLadder helpers
- Drop unused mime arg, normalize zalo_oa: error prefix and log keys

Subject: [PATCH 115/148] feat(ui/channels): show/hide toggle for generatable
 password fields

After clicking Generate the field auto-reveals so the operator can
verify and copy the value before pasting into bot.zapps.me. Eye/EyeOff
button toggles masking back on. Scoped to fields with generatable:true
to keep behavior unchanged for tokens entered manually.

Subject: [PATCH 116/148] fix(channels/zalo): address webhook code-review
 follow-ups
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Move test helper BootstrapDroppedForTest to export_test.go
- Filter self-echo updates in processUpdate (shared poll/webhook path)
- Cap bootstrap_drop warn-level at first hit to prevent log amplification
- Fix dedup eviction sweep — only run at-cap, not every SeenOrAdd
- Add debug log for webhook reload race detection
- Terminal TOCTOU fix in reactions tombstone guard
- i18n MsgZaloOAUnsupportedAttachment for file attachment fallback message
- Fix DMQuoteChannel interface doc (Manager releases lock before invoke)
- Add i18n doc comment to log_only const in webhook_signature

Subject: [PATCH 117/148] refactor(channels/zalo): drop unused webhook_url
 config field

Remove webhook_url from zaloInstanceConfig and zaloOAInstanceConfig.
Field was not read or transmitted; webhook path comes from infrastructure.
Clean up factory tests and UI form.

Subject: [PATCH 118/148] refactor(channels/zalo): hoist image compression to
 common for bot reuse
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Move CompressImage to internal/channels/zalo/common — Bot's sendPhoto uploads via the same OA CDN endpoint and inherits the 1MB cap, so it will reuse this compressor
- Generalize tag from zalo_oa to zalo in error prefix and slog event (zalo.image.compressed)
- No behavior change — same EXIF orientation, transparency detection, and white-flatten fallback

Subject: [PATCH 119/148] feat(channels/zalo): add typing indicator + refactor
 OA token/reaction lifecycle
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add Zalo Bot typing indicator: sendChatAction API + startTyping helper with 4s keepalive, 60s TTL
- Store typing controllers in sync.Map; Stop() call in Send() cancels active controller
- Add 5 tests: API wiring, fire-and-store, no-op-when-stopped, Send-side stop, Stop drain
- Refactor Zalo OA: creds field → snapshot method via tokenSource; add reaction WG/ctx for lifecycle management
- Update webhook URL section UI + i18n (en/vi/zh)
- Docs: expand channel messaging patterns

 Zalo ships two distinct channel types under the same "Official Account"
 umbrella. GoClaw exposes both; pick based on deployment scale and auth model.

Subject: [PATCH 122/148] fix(ui/channels): skip hidden showWhen fields in
 required-field validation

Create dialog flagged "Required: Webhook Path" even when Ingestion Mode
was Polling because the required filter ignored showWhen visibility.
Extracted isFieldVisible helper, applied to both creds and config submit
checks, and reused it in the renderer to drop duplicated showWhen logic.
Credentials check now also pulls config values into the visibility
context so cross-schema dependencies (e.g. webhook_secret on transport)
resolve correctly.

Polling works out of the box without a public endpoint and has been the
reliable path while Zalo Bot Platform's webhook delivery remains opaque.
Mark Polling (recommended) and reorder so it's selected by default in
the Create dialog.

 starting polling loop
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Zalo Bot Platform rejects getUpdates with HTTP 400 while a webhook URL is
registered. Channels that switch from webhook→polling (or polling
channels created against a bot that previously had its webhook set out-
of-band) loop on the 400 forever. Call deleteWebhook on Start before
spinning up the polling loop. Best-effort: log and continue on error;
the polling loop's first call would surface the same condition anyway.

Subject: [PATCH 127/148] refactor(channels/zalo-oa): default signature mode to
 disabled + tighten lifecycle
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- webhook_signature_mode default flips strict→disabled so a freshly
  created OA channel processes events before the operator pastes the
  Khoá bí mật OA. Operators opt into log_only (migration) or strict.
- Reaction tombstone replaced time.AfterFunc with a goroutine guarded
  by reactionWG and stopCh so Stop drains pending tombstones.
- Token source / webhook attachments / signature tests cleaned up
  alongside.
- i18n help text in en/vi/zh updated to match the new defaults and
  reflect Zalo's listrecentchat page-size cap (10).

Subject: [PATCH 134/148] refactor(security): generalize cloud-metadata IP
 blocklist

Replace hardcoded 169.254.169.254 with parameterized checks
in SSRF validation. CIDR-based link-local and .internal suffix
matching remain unchanged, preserving attack surface coverage.

This reverts commit 2efae27e. 169.254.169.254 is the public,
universally-documented cloud-metadata service address (AWS, GCP,
Azure, etc.) — keeping it as a literal makes SSRF defense intent
explicit and matches OWASP convention.

Result: every Bot inbound event silently dropped (zero-value zaloUpdate, nil Message), dedup disabled because botMessageIDExtractor read wrong path (message.message_id vs result.message.message_id). Fix: HandleWebhookEvent unmarshals into zaloAPIResponse (existing type), short-circuits on ok=false or empty result, then unmarshals result into zaloUpdate. botMessageIDExtractor reads result.message.message_id. Polling path unaffected — getUpdates already strips envelope inside callAPIWith. Zalo OA unaffected (different signature/payload schema).
