Usage Examples

# List purchased courses
opencli xiaoe courses

# Read course metadata
opencli xiaoe detail "https://appxxxx.h5.xet.citv.cn/p/course/ecourse/v_xxxxx"

# Read the course outline
opencli xiaoe catalog "https://appxxxx.h5.xet.citv.cn/p/course/ecourse/v_xxxxx"

# Resolve a lesson M3U8 URL
opencli xiaoe play-url "https://appxxxx.h5.xet.citv.cn/v1/course/video/v_xxxxx?product_id=p_xxxxx" -f json

# Extract page content
opencli xiaoe content "https://appxxxx.h5.xet.citv.cn/v1/course/text/t_xxxxx"

Output

content

Column Type Notes
title string document.title of the rich-text page
content string Trimmed innerText from the first matching content selector (.rich-text-wrap, .content-wrap, .article-content, .text-content, .course-detail, .detail-content, [class*="richtext"], [class*="rich-text"], .ql-editor); falls through to <main> → #app → <body> if no selector matches. No silent truncation — full extracted text is returned.
content_length int content.length — useful for caller-side truncation decisions
image_count int Count of <img> whose src is xiaoe-hosted and not a data: URI. No silent slice — counts the entire page.

Empty content (e.g. login expired, page renders an empty shell) raises EmptyResultError instead of returning a row with content=''.

catalog

Column Type Notes
ch int 1-based chapter index
chapter string Chapter title (or course name for column resources)
no int 1-based section index within the chapter
title string Section title
type string Resource label: 图文 / 直播 / 音频 / 视频 / 专栏 / 大专栏; unknown types pass through as the raw String(t) rather than being silently swallowed
resource_id string Xiaoe resource identifier (p_xxx / v_xxx / l_xxx / a_xxx / i_xxx)
url string Canonical playback / reading URL — '' when xiaoe did not expose enough fields to construct one (no synthetic URL)
status string 已完成 / <n>% / 未学 for normal courses; 已完成 / <n>节 / '' for column resources

courses

Column Type Notes
title string Course title from the card
shop string Shop name (shop_name) or app name (app_name); empty when the Vue tree did not expose either
url string Canonical course URL: entry.h5_url → entry.url → built from app_id + resource_id (column courses get /v1/course/column/<id>?type=3, everything else gets /p/course/ecourse/<id>); returns '' when none of the three are available — never a synthetic partial URL

Validation

Empty results raise EmptyResultError, never silent [] — for browser adapters this almost always indicates the cookie has expired or the URL is not a course page. The positional url argument is required for content / catalog / detail / play-url; missing url raises ArgumentError before any browser navigation happens.

Prerequisites

Notes

  • courses starts from study.xiaoe-tech.com and matches purchased course cards back to Vue data to recover shop names and course URLs
  • catalog supports normal courses, columns, and big columns by reading Vuex / Vue component state after the course page loads
  • play-url uses a direct API path for video lessons and falls back to runtime resource inspection for live replays
  • Cross-shop course URLs are preserved, so you can take a URL from courses and pass it directly into detail, catalog, play-url, or content
  • catalog, courses, and content extract pure helpers (typeLabel, buildItemUrl, chapterUrlPath, buildCourseUrl, pickContentText, countXiaoeImages) that are unit-tested directly in clis/xiaoe/xiaoe.test.js — the in-page IIFEs embed those same functions via ${fn.toString()} so the live and the test paths share one source of truth
