尝试直接访问 request.body()，但请求体已经被消费。

Workarounds

  1. 85% success 
    async def body_middleware(request, call_next):
    body = await request.body()
    request._body = body
    response = await call_next(request)
    return response

Dead Ends

Common approaches that don't work:

  1. 90% fail

    请求体只能读取一次，第二次会抛出异常

  2. 60% fail

    stream 需要正确管理，否则会导致内存泄漏
