Python连接Java Socket服务端

java服务端单线程示例

import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.net.ServerSocket;
import java.net.Socket;

/**
 * Server
 */
public class Server {
    public static void main(String[] args) throws IOException {
        ServerSocket server = new ServerSocket(2580);
        Socket socket = server.accept();
        InputStream is = socket.getInputStream();
        OutputStream out=null;
        byte[] bytes = new byte[2048];
        int len = 0;
        String results = null;
        try {
            len = is.read(bytes, 0, 2048);
            results = new String(bytes, 0, len);
            System.out.println("from Client information:" + results);
            out=socket.getOutputStream();
            out.write("J-S-P_ I am Server".getBytes());
        } catch (IOException e) {
            e.printStackTrace();
        }
       
        server.close();
        System.out.println("结束");

    }
}

Python客户端单线程示例

from socket import *

serverName = '127.0.0.1'
serverPort = 2580
BUFSIZ = 2048
ADDR = (serverName, serverPort)

clientSocket = socket(AF_INET, SOCK_STREAM)
clientSocket.connect(ADDR)
clientSocket.send("J-S-P_ I am Client".encode('utf-8'))
returnData = clientSocket.recv(BUFSIZ)
print('from Server information:%s' % returnData.decode('utf-8'))
clientSocket.close()
print("结束")
