Root Cause

The HTTP method used in the request is not allowed for the route (e.g., POST on a GET-only route).

generic

中文

请求中使用的HTTP方法不被路由允许（例如，在仅接受GET的路由上使用POST）。

Workarounds

  1. 95% success Add the correct method to the route decorator 
    @app.route('/login', methods=['GET', 'POST'])
def login():
    return "Login page"
  2. 90% success Use the correct HTTP method in the request 
    curl -X POST http://localhost:5000/login

Dead Ends

Common approaches that don't work:

  1. Changing the request method without checking the route 60% fail

    May cause other errors if the route expects specific methods.

  2. Adding a catch-all route without methods 75% fail

    Can override intended behavior and cause security issues.
