本文实例讲述了Go语言服务器开发之简易TCP客户端与服务端实现方法。分享给大家供大家参考。具体实现方法如下：

Go语言具备强大的服务器开发支持，这里示范了最基础的服务器开发：通过TCP协议实现客户端与服务器的通讯。

一服务端，为每个客户端新开一个goroutine

复制代码代码如下:func ServerBase() {
    fmt.Println("Starting the server...")
    //create listener
    listener, err := net.Listen("tcp", "192.168.1.27:50000")
    if err != nil {
        fmt.Println("Error listening:", err.Error())
        return
    }

    // listen and accept connections from clients:
    for {
        conn, err := listener.Accept()
        if err != nil {
            fmt.Println("Error accepting:", err.Error())
            return
        }
        //create a goroutine for each request.
        go doServerStuff(conn)
    }
}

func doServerStuff(conn net.Conn) {
    fmt.Println("new connection:", conn.LocalAddr())
    for {
        buf := make([]byte, 1024)
        length, err := conn.Read(buf)
        if err != nil {
            fmt.Println("Error reading:", err.Error())
            return
        }

        fmt.Println("Receive data from client:", string(buf[:length]))
    }
}

二客户端连接服务器，并发送数据
复制代码代码如下:func ClientBase() {
    //open connection:
    conn, err := net.Dial("tcp", "192.168.1.27:50000")
    if err != nil {
        fmt.Println("Error dial:", err.Error())
        return
    }

    inputReader := bufio.NewReader(os.Stdin)
    fmt.Println("Please input your name:")
    clientName, _ := inputReader.ReadString('\n')
    inputClientName := strings.Trim(clientName, "\n")

    //send info to server until Quit
    for {
        fmt.Println("What do you send to the server")
        content, _ := inputReader.ReadString('\n')
        inputContent := strings.Trim(content, "\n")
        if inputContent == "Q" {
            return
        }

        _, err := conn.Write([]byte(inputClientName + " says " + inputContent))
        if err != nil {
            fmt.Println("Error Write:", err.Error())
            return
        }
    }
}
