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")
