推荐答案

问题不在于 PreparedAttachment 与基础网络。看起来服务器发送的字节数超过了 Content-Length 标头规定的字节数。这可能与您使用的服务器有关。

The problem isn't with PreparedAttachment its with the underlying networking. It would appear that server sent more bytes than then Content-Length header stipulated. This is probably a bug with the server you using.
