代码
# -- coding: utf-8# 开始一直报错，发现是文件夹命名中文的问题import sockettarget_host = "127.0.0.1"target_port = 9999# 建立一个socket对象client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)# 连接客户端client.connect((target_host, target_port))# 发送数据client.send("GET / HTTP/1.1\r\nHost: \r\n\r\n")# 接收数据response = client.recv(4096)print response
利用NetAssist 模拟客户端发送接收回复的过程。
1.打开NetAssist，设置为TCP Server，点击打开
2.客户端设置好ip端口，运行，发送消息
接收消息成功
3.服务端回复消息，客户端接收成功。
TCP服务端
