 ## 接口说明
 
-- `POST /api/upload-txt`
-  - 上传 TXT（字段名 `file`），每行一个 URL；支持 `#` 注释与空行
-  - 响应项示例：
-    - `{
-        "url": "https://cdn.jsdmirror.com/npm/bootstrap@5.3.0/dist/css/bootstrap.min.css",
-        "saved": "/css/npm/bootstrap@5.3.0/dist/css/bootstrap.min.css",
-        "accessUrl": "https://<你的域名>/css/npm/bootstrap@5.3.0/dist/css/bootstrap.min.css",
-        "filename": "bootstrap.min.css",
-        "type": "css",
-        "size": 232914,
-        "skipped": false
-      }`
-
-- `POST /api/cache`
-  - 提交单条 `url` 或数组 `urls`
-  - 单条示例：`{"url":"https://.../bootstrap.min.css"}`
-  - 多条示例：`{"urls":["https://.../bootstrap.min.css","https://.../bootstrap.bundle.min.js"]}`
-
 - `GET /api/seed`
   - 从项目内置 `seed.txt` 读取并批量抓取，无需重启
+  - 管理抓取仅通过修改服务器上的 `seed.txt` 实现，服务端不接受外部提交 URL
