根因分析
客户端取消请求或服务器上下文因超时或客户端断开而取消,导致 HTTP 处理器中止。
English
The client canceled the request or the server's context was canceled due to timeout or client disconnect, causing the HTTP handler to abort.
解决方案
-
90% 成功率
Check for context cancellation and return early: if r.Context().Err() != nil { return } -
70% 成功率
Use http.Server with ReadTimeout and WriteTimeout properly: &http.Server{ReadTimeout: 10*time.Second, WriteTimeout: 10*time.Second}
无效尝试
常见但无效的做法:
-
80% 失败
Processing continues but the client is gone; results are wasted and may cause resource leaks.
-
60% 失败
Long timeouts can lead to resource exhaustion and don't address client-initiated cancellations.
