网络编程

服务器端

1.创建一个ServerSocket对象，指定端口  

2.监听客户端请求accept（）

3.打开输入流，接收用户请求

4.关闭资源 

public static void main(String[] args) {
        try {
            ServerSocket serverSocket = new ServerSocket(8000);
            Socket socket = serverSocket.accept();
            InputStream is = socket.getInputStream();
            
            BufferedReader reader = new BufferedReader(new InputStreamReader(is));
            
            String information = null;
            
            while((information = reader.readLine())!= null) {
                System.out.printf("我是服务器端，接收的数据为：%S",information);
            }
            reader.close();
            is.close();
            socket.close();
            serverSocket.close();
            
        } catch (IOException e) {
            // TODO: handle exception
            e.printStackTrace();
        }
    
        
    }

客户端

1.创建一个Socket对象

2.打开输出流，发送用户请求

3.关闭资源

public static void main(String[] args) {
        try {
            Socket socket = new Socket("localhost", 8000);
            OutputStream os = socket.getOutputStream();
            String info = "账户：admin,密码：123456";
            os.write(info.getBytes());

            os.close();
            socket.close();

        } catch (IOException e) {
            // TODO: handle exception
        }
    }
