go proxy

• 一定要按照下边的方式, 设置好proxy, 不然依赖包下载巨慢!~

1. 如何stop

unix domain socket

Understanding Unix Domain Sockets in Golang - DEV Community —> 终于搞懂了!~

• 可以基于unix domain socket来创建普通的Socket Server, 或者HTTP Server
• 想要往 unix domain socket 里发送请求:
  • 命令行方式: curl nc 等, 都需要指定相关的参数, 来说明是往Unix Domain Socket里发送.
  • Client方式:

unix domain socket —> http server

const socketPath = "/tmp/test.sock"

func ListenUnixSocket() error {
	socket, err := net.Listen("unix", socketPath)
	if err != nil {
		log.Printf("Failed to listen to socket registry")
		return err
	}

	c := make(chan os.Signal, 1)
	signal.Notify(c, os.Interrupt, syscall.SIGTERM)
	go func() {
		<-c
		os.Remove(socketPath)
		os.Exit(1)
	}()

	r := mux.NewRouter()
	r.HandleFunc("/", ProductsHandler)
	r.HandleFunc("/hello", HelloHandler)

	srv := &http.Server{Handler: r}
	err = srv.Serve(socket)
	return err
}
