golang chat rooms (c)

Implement multiple clients simultaneously sends a message to the server, the server to accept and print it out

client1

func main() {
	var conn, err = net.DialTimeout("tcp", "127.0.0.1:5888", 30*time.Second)
	if err != nil {
		log.Fatal("conn error")
	}
	for {
		conn.Write([]byte("user 2"))
		time.Sleep(3 * time.Second)
	}
	conn.Close()
}

client2

func main() {
	var conn, err = net.DialTimeout("tcp", "127.0.0.1:5888", 30*time.Second)
	if err != nil {
		log.Fatal("conn error")
	}
	for {
		conn.Write([]byte("user 1\n "))
		time.Sleep(2 * time.Second)
	}
	conn.Close()
}

server

func main() {
	var conn, err = net.Listen("tcp","127.0.0.1:5888")
	if err != nil {
		return
	}
	for {
		c, err := conn.Accept()
		if err != nil {
			return
		}
		go Receive(c)

	}
}

func Receive(c net.Conn) {
	for {
		byte := make([]byte, 256)
		lens, err := c.Read(byte)
		if err != nil {
			log.Fatal("Receive error")
		}
		byte = byte[:lens]
		fmt.Printf("%s\n", byte)
	}

}

The next target

Specifies the broadcast message to the client
