请教 Golang HTTP 的 Shutdown 函数

[jinliming2]

server.Shutdown 也会直接中断正在发数据的连接吗？

不 Shutdown 的话正常应该发送 60 个 asd，我在第 5 个调用了 Shutdown，连接直接被中断了。

请问一下大家这个是怎么回事？

var server *http.Server
server = &http.Server{
	IdleTimeout: 60*time.Second,
	WriteTimeout: 60*time.Second,
	Handler: http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
		w.Header().Set("Content-Length", "181")
		w.WriteHeader(200)
		for i := 0; i < 60; i++ {
			if i == 5 {
				//server.SetKeepAlivesEnabled(false)
				_, _ = w.Write([]byte("zxc"))
				fmt.Println(server.Shutdown(context.Background()))
				_, _ = w.Write([]byte("qwe"))
			}
			_, _ = w.Write([]byte("asd"))
			if flusher, ok := w.( http.Flusher); ok {
				flusher.Flush()
			} else {
				fmt.Println("Not flushable")
			}
			//time.Sleep(time.Second)
		}
		_, _ = w.Write([]byte("\n"))
	}),
}
err = server.Serve(ServeHTTP)
fmt.Println(err)

https://golang.org/pkg/net/http/#Server.Shutdown

When Shutdown is called, Serve, ListenAndServe, and ListenAndServeTLS immediately return ErrServerClosed. Make sure the program doesn't exit and waits instead for Shutdown to return.

// Shutdown works by first closing all open
// listeners, then closing all idle connections, and then waiting
// indefinitely for connections to return to idle and then shut down.

补充楼上，waiting indefinitely.

非常感谢，加一个 chan 等一下就好了，成功了
