| 1 | +# Implementation Summary: Unified API Registry System |
| 2 | + |
| 3 | +## Problem Statement (Chinese) |
| 4 | + |
| 5 | +> 系统会有很多套Api,包括graphql, odata rest file,auth,包括插件自己注册的Api,如何统一登记管理这些API并且能够提供统一的API查看测试界面比如swagger |
| 6 | +
|
| 7 | +## Problem Statement (English Translation) |
| 8 | + |
| 9 | +> "The system has many sets of APIs, including GraphQL, OData, REST, File, Auth, and APIs registered by plugins themselves. How to uniformly register and manage these APIs and provide a unified API viewing and testing interface like Swagger?" |
| 10 | +
|
| 11 | +## Solution Overview |
| 12 | + |
| 13 | +We have implemented a comprehensive **Unified API Registry and Documentation System** that provides: |
| 14 | + |
| 15 | +1. **Centralized API Registration** - One registry for all API types |
| 16 | +2. **Multiple Protocol Support** - REST, GraphQL, OData, WebSocket, File, Auth, Plugin APIs, etc. |
| 17 | +3. **Swagger-like Documentation** - OpenAPI 3.0 specification generation |
| 18 | +4. **Interactive Testing Interface** - Multiple UI options (Swagger UI, Redoc, GraphQL Playground, etc.) |
| 19 | +5. **API Discovery** - Query and filter APIs by various criteria |
| 20 | +6. **Plugin Support** - First-class support for plugin-registered APIs |
| 21 | + |
