Python与Java之间Socket通信

• python socket server

import socket

try:
    sock=socket.socket(socket.AF_INET,socket.SOCK_STREAM);
    print("create socket succ!")

    sock.bind(('192.168.1.38',50006))
    print('bind socket succ!')

    sock.listen(5)
    print('listen succ!')

except:
    print("init socket error!")

while True:
    print("listen for client...")
    conn,addr=sock.accept()
    print("get client")
    print(addr)

    conn.settimeout(30)
    szBuf=conn.recv(1024)
    print("recv:"+str(szBuf,'gbk'))

    if "0"==szBuf:
        conn.send(b"exit")
    else:
        conn.send(b"welcome client")

    conn.close()
    print("end of servive")

• python socket client

import socket
HOST = '192.168.1.38'
PORT = 50006

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect((HOST, PORT))
sock.send("232132132131".encode())

szBuf = sock.recv(1024)
byt = 'recv:' + szBuf.decode('utf-8')
print(byt)

sock.close()

• java socket client

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.OutputStream;
import java.io.PrintWriter;
import java.net.Socket;
import java.net.UnknownHostException;


public class SocketClient {

    public static void main(String args[])throws Exception {

        try {
            Socket socket = new Socket("192.168.1.38",50006);

            //获取输出流，向服务器端发送信息
            OutputStream os=socket.getOutputStream();//字节输出流
            PrintWriter pw=new PrintWriter(os);//将输出流包装为打印流
            pw.write("我是Java服务器");
            pw.flush();
            socket.shutdownOutput();//关闭输出流

            InputStream is=socket.getInputStream();
            BufferedReader in = new BufferedReader(new InputStreamReader(is));
            String info=null;
            while((info=in.readLine())!=null){
                System.out.println("我是客户端，Python服务器说："+info);
            }
            is.close();
            in.close();
            socket.close();
        } catch (UnknownHostException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

• 值得注意的是，这里的服务器域名应该写本电脑上的ip,而不是127.0.0.1
