Root Cause

The route exists but does not declare the HTTP method used (e.g. POST to a GET-only route).

generic

中文

路由存在但未声明所使用的HTTP方法（例如对仅支持GET的路由发起POST）。

Workarounds

  1. 96% success 
    @app.route('/x', methods=['POST'])\ndef x(): ...
  2. 94% success 
    @app.get('/x')\[email protected]('/x')\ndef x(): ...

Dead Ends

Common approaches that don't work:

  1. 80% fail

    Does not enable POST; the 405 remains for POST requests.

  2. 75% fail

    Masks the real routing issue; clients still call the wrong method.
