1. TCP 协议

　　[TCP Server]

　　通过 netstat -ano 查看端口是否开启

# -*-coding:utf-8-*-"""TCP 协议的 Socket 编程，Server 端Server 端绑定到指定地址，监听特定的端口，接受发来的连接请求
"""
import threading
import socket
import timeclass CommThread(threading.Thread):def run(self):while True:# 接受数据data = sock.recv(4096)print("收到了%s = %s" % (str(self.addr), str(data)), )def __init__(self, sock, addr):threading.Thread.__init__(self)self.sock = sockself.addr = addr# 创建服务器套接字，绑定端口
ss = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
ss.bind(("127.0.0.1", 8888))
ss.listen(0)while True:sock, addr = ss.accept()CommThread(sock, addr).start()print("%s链接进来\r\n" % (str(addr)), )time.sleep(1)

 

　　[TCP Client]

 

# -*-coding:utf-8-*-
"""TCP 协议的 Socket 编程，Client 端
"""
import threading
import socket
import time# 创建服务器套接字，绑定端口
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect(("127.0.0.1" , 8888))i = 1
while True:str = "tom%d\r\n" % (i)print ("client : " + str),sock.send(bytes(str,'utf-8'))time.sleep(1)i += 1

2. UDP 协议

　　[UDP Server]

 

# -*-coding:utf-8-*-"""UDP 协议的 Socket 编程，Server 端
"""
import socket# 创建 UDP 接收方
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
sock.bind(("192.168.13.6", 9999))i = 1
while True:data = sock.recv(4096)print(str(data))

 

　　[UDP Client]

 

# -*-coding:utf-8-*-
"""UDP 协议的 Socket 编程，Client 端
"""import socket
import time# 创建 UDP 发送方
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
sock.bind(("192.168.13.6", 8888))i = 1
while True:sock.sendto(bytes(("tom" + str(i)),'utf-8'), ("192.168.13.255", 9999))i += 1time.sleep(1)
