(一)TCP连接方式

1.TCP服务端

import socket #创建一个socket: server = socket.socket(socket.AF_INET, socket.SOCK_STREAM) #绑定IP端口: server.bind(('192.168.8.1', 8090)) #监听: server.listen(5) print('服务器启动成功......') #等待连接: clientSocket, clientAddress = server.accept() print('客户端连接成功......') count = 1 while True: data = clientSocket.recv(1024) #接收数据 print('接收到来自%s的数据:%s' % (clientAddress, str(data.decode('utf-8')))) info = input('服务器的回复:') #'第' + str(count) +'此回复:' clientSocket.send(info.encode('UTF-8')) count += 1

2.TCP客户端

import socket if __name__ == '__main__': #创建客户端: client = socket.socket(socket.AF_INET, socket.SOCK_STREAM) #连接服务器: client.connect(('192.168.8.1', 8090)) count = 0 while True: data = input('请输入要发送的数据:') count += 1 #发送数据: client.send(data.encode('UTF-8')) #接收数据: info = client.recv(1024) print('服务器说:%s' % info.decode('UTF-8'))

(二)UDP连接方式

1.UDP服务端

import socket udpServer = socket.socket(socket.AF_INET,socket.SOCK_DGRAM) udpServer.bind(('192.168.8.1', 8070)) while True: data, addr = udpServer.recvfrom(1024) print('客户端说:', data.decode('UTF-8')) info = input('回复客户端:') udpServer.sendto(info.encode('UTF-8'), addr)

2.UDP客户端

import socket client = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) while True: data = input('请输入要发送的数据:') #发送数据: client.sendto(data.encode('UTF-8'), ('192.168.8.1', 8070)) #接收数据: info = client.recv(1024).decode('UTF-8') print('服务器说:', info)
