Root Cause

The server expects a non-zero ContentLength but the request body is empty, causing a protocol violation.

generic

中文

服务器期望非零的 ContentLength，但请求体为空，导致协议违规。

Workarounds

  1. 85% success 
    Ensure the request body is non-empty or set ContentLength to -1 for chunked encoding.

Dead Ends

Common approaches that don't work:

  1. 50% fail

    This can cause the server to read beyond the body and fail.

  2. 60% fail

    This changes the semantics of the request.
