关于 golang 一分钟处理百万请求的疑问

每分钟百万级请求 比如这段是这样子的回调，http.HandleFunc("/", payloadHandler)， 只是把一个 http 请求塞进 chan chan Job 里，可能并没有等到处理就返回给请求 200 了。 func payloadHandler(w http.ResponseWriter, r *http.Request) { if r.Method != "POST" { w.WriteHeader( http.StatusMethodNotAllowed) return } // Read the body into a string for json decoding var content = &PayloadCollection{} err := json.NewDecoder(io.LimitReader(r.Body, MaxLength)).Decode(&content) if err != nil { w.Header().Set("Content-Type", "application/json; charset=UTF-8") w.WriteHeader( http.StatusBadRequest) return } // Go through each payload and queue items individually to be posted to S3 for _, payload := range content.Payloads { // let's create a job with the payload work := Job{Payload: payload} // Push the work onto the queue. JobQueue <- work } w.WriteHeader( http.StatusOK) } 到了从双层队通道取 Job 时候，处理的结果并不会通知给 http 请求方， // Start method starts the run loop for the worker, listening for a quit channel in // case we need to stop it func (w Worker) Start() { go func() { for { // register the current worker into the worker queue. w.WorkerPool <- w.JobChannel select { case job := <-w.JobChannel: // we have received a work request. if err := job.Payload.UploadToS3(); err != nil { log.Errorf("Error uploading to S3: %s", err.Error()) } case <-w.quit: // we have received a signal to stop return } } }() } 我是想实现能实时支持的方式，还把w http.ResponseWriter也套进了 Job 里面，想等真正有结果在w.Write。 结果发现接受的不到 Response.Body。应该是返回比处理要早。 所以不知道是不是这种模式 ，只能实现异步。
