English

Attempting to write a response to a client connection that has already been closed, often due to a timeout or client disconnect.

解决方案

  1. 85% 成功率 
    if err := json.NewEncoder(w).Encode(data); err != nil {
    log.Printf("Error writing response: %v", err)
}
  2. 80% 成功率 
    Use context cancellation to detect client disconnects early.

无效尝试

常见但无效的做法:

  1. 70% 失败

    The write will fail silently, and the client will never receive the response.

  2. 90% 失败

    The issue is not buffer size but connection state.
