This article mainly introduces the client and server handshake of python Socket in detail. It has certain reference value. Interested friends can refer to

to learn how to use socket simply. Establish a connection between the client and the server and send data

1. Client socketClient.py code


import socket 
 
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) 
# 建立连接: 
s.connect(('127.0.0.1', 9999)) 
# 接收欢迎消息: 
print(s.recv(1024).decode('utf-8')) 
for data in [b'Michael', b'Tracy', b'Sarah']: 
 # 发送数据: 
 s.send(data) 
 print(s.recv(1024).decode('utf-8')) 
s.send(b'exit') 
s.close()

2. Server serverSocket.py Code


import socket 
import threading 
import time 
# from threading import Thread 
 
 
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) 
# 监听端口: 
s.bind(('127.0.0.1', 9999)) 
s.listen(5) 
print('Waiting for connection...') 
 
def tcplink(sock, addr): 
 print('Accept new connection from %s:%s...' % addr) 
 sock.send(b'Welcome!') 
 while True: 
  data = sock.recv(1024) 
  time.sleep(1) 
  if not data or data.decode('utf-8') == 'exit': 
   break 
  sock.send(('Hello, %s!' % data.decode('utf-8')).encode('utf-8')) 
 sock.close() 
 print('Connection from %s:%s closed.' % addr) 
 
while True: 
 # 接受一个新连接: 
 sock, addr = s.accept() 
 # 创建新线程来处理TCP连接: 
 t = threading.Thread(target=tcplink, args=(sock, addr)) 
 t.start()

3. Operation process

Open two console windows, first run the server python3 serverSocket.py

and then run Client python3 socketClient.py
