Root Cause

The HTTP method used (e.g., POST) is not allowed for the requested endpoint.

generic

中文

使用的 HTTP 方法（例如 POST）不允许用于请求的端点。

Workarounds

  1. 90% success Define route with correct methods 
    from starlette.routing import Route
async def handle(request):
    return PlainTextResponse('OK')
app.add_route('/data', handle, methods=['POST'])
  2. 95% success Use method-specific decorators 
    @app.post('/data')
async def create(request):
    return JSONResponse({'status': 'created'})

Dead Ends

Common approaches that don't work:

  1. Assuming all methods are allowed by default 80% fail

    Starlette requires explicit method registration.

  2. Using GET when POST is required 70% fail

    Method mismatch leads to 405.
