根因分析

服务器写入超时在写入响应体期间到期，导致连接突然关闭。

English

The server's WriteTimeout expired while writing the response body, causing the connection to be closed abruptly.

generic

解决方案

  1. 80% 成功率 
    Set a reasonable WriteTimeout and handle errors from Write: if _, err := w.Write(data); err != nil { return }
  2. 75% 成功率 
    Use http.TimeoutHandler to wrap handlers and return a timeout response: http.TimeoutHandler(handler, 30*time.Second, "timeout")

无效尝试

常见但无效的做法:

  1. 70% 失败

    May cause slow clients to hold connections indefinitely, leading to resource exhaustion.

  2. 90% 失败

    Writes will fail silently; data is corrupted and the connection is already closed.
