TCP客户端与服务器通信示例-优快云博客

本文通过一个简单的示例展示了TCP客户端与服务器之间的通信过程。客户端连接到服务器后发送消息“TCP编程”，服务器接收并打印该消息，然后回复客户端“收到数据”。此示例涉及Socket编程的基础知识。

客户端代码：

 try {
        Socket socket=new Socket("100.66.12.204",10002);
        InputStream inputStream=socket.getInputStream();
        OutputStream outputStream=socket.getOutputStream();
        byte[] bytes1="TCP编程".getBytes();
        outputStream.write(bytes1);
        System.out.println("客户端发送成功");
        socket.shutdownOutput();
        byte[] bytes=new byte[1024];
        int len;
        while((len=inputStream.read(bytes))!=-1)
        {
            System.out.println("服务器:"+new String(bytes,0,len));
        }
        socket.close();
    } catch (Exception e) {
        e.printStackTrace();
    }
}

服务器代码：

public static void main(String[] args) {
    try {
        ServerSocket serverSocket=new ServerSocket(10002);
       Socket socket= serverSocket.accept();
        InputStream inputStream=socket.getInputStream();
        int len;
        byte[] bytes=new byte[1024];
        while((len=inputStream.read(bytes))!=-1)
        {
            System.out.println("客户端:"+new String(bytes,0,len));
        }
        String ip=socket.getInetAddress().getHostAddress();
        int port=socket.getPort();
        System.out.println("ip::"+ip+"port::"+port);
        OutputStream outputStream=socket.getOutputStream();
        byte[] bytes1="收到数据".getBytes();
        //outputStream.write(bytes1);
        outputStream.write(bytes1);
        System.out.println("服务器发送成功");
        socket.close();
    } catch (Exception e) {
        e.printStackTrace();
    }
}
