Root Cause

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

generic

中文

请求的URL存在但不支持使用的HTTP方法（例如，对仅GET的路由使用POST）。

Workarounds

  1. 95% success 
    Specify allowed methods explicitly: @app.route('/submit', methods=['POST'])
  2. 90% success 
    Use method checking in the view: if request.method == 'POST':\n    # handle POST\nelse:\n    abort(405)

Dead Ends

Common approaches that don't work:

  1. 70% fail

    Catching MethodNotAllowed and redirecting to the same URL can cause infinite loops.

  2. 80% fail

    Changing the route to accept all methods may expose unintended functionality.
