python socket编辑示例 tcp

服务端代码：

from socket import socket, AF_INET, SOCK_STREAM# 1. 创建socket对象   AF_INET：用于internet之间的进程通信，SOCK_STREAM：表示TCP协议
server_socket = socket(AF_INET, SOCK_STREAM)# 2. 绑定ip和端口号
ip = '127.0.0.1'
port = 8888
server_socket.bind((ip, port))# 3. 开始监听 最大监听数量
server_socket.listen(5)
# print('服务器已经启动')# 4. 等待客户端连接
clinic_socket, clinic_addr = server_socket.accept()# 5. 接收客户端数据
data = clinic_socket.recv(1024).decode('utf-8')
while data != 'bye':if data != '':print("clinic：", data)inputData = input('serv：')clinic_socket.send(inputData.encode('utf-8'))  # 响应if inputData == 'bye':breakdata = clinic_socket.recv(1024).decode('utf-8')# 关闭socket
clinic_socket.close()
server_socket.close()

客户端代码：

import socket# 1. 创建对象
clinic_socket = socket.socket()# 2. ip地址端口 连接
ip = '127.0.0.1'
port = 8888
clinic_socket.connect((ip, port))
# print('与服务器连接成功')# 3. 发送数据
# clinic_socket.send('Welcome to python world'.encode('utf-8'))
info = ''  # 服务器接收到的数据
while info != 'bye':send_data = input('clinic：')clinic_socket.send(send_data.encode('utf-8'))if send_data == 'bye':breakinfo = clinic_socket.recv(1024).decode('utf-8')print('serv：', info)# 4. 关闭
clinic_socket.close()
