Root Cause

The requested URL path doesn't match any defined route, possibly due to trailing slash mismatch.

generic

中文

请求的 URL 路径与任何定义的路由不匹配，可能是由于尾部斜杠不匹配。

Workarounds

  1. 90% success 
    Define the route with optional trailing slash: @app.route('/items/{path:path}') or use redirect_slashes=True
  2. 80% success 
    Ensure the client sends the correct path: /items (without trailing slash) if your route is '/items'

Dead Ends

Common approaches that don't work:

  1. 50% fail

    If the client doesn't send the slash, it still won't match; you need redirect_slashes=True (default).

  2. 40% fail

    May hide actual errors; better to define specific routes.
