connectsend responseClient+start_client()Server+start_server() 总结 通过本文的介绍,我们学习了 TCP/IP 通讯的基本概念及其在 Python 中的实现。我们创建了一个简单的 TCP 服务器和客户端示例,并实现了基本的数据交换。 TCP/IP 协议为我们的网络通讯提供了基础。 Python 的 socket 模块使得 TCP/IP 网络编程变...

使用Python模拟TCP/IP协议栈 1. 代码如下import randomclass ApplicationLayer: def send_data(self, data): print(f"Application Layer: Sending data: {data}") return datadef receive_data(self, data): print(f"Application Layer: Received data: {data}")...
第一次挥手:当客户端A要断开TCP连接时,发送一个包,其中标志位FIN=1,ACK=1,发送序号SEQ=X,确认序号ACK=Z,Client进入FIN_WAIT状态。 第二次挥手:客户B知道A要断开后,发送一个确认包,其中标志位ACK=1,发送序号SEQ=Z确认序号ACK=x+1,Server进入CLOSE_WAIT状态。
调用accept()等待客户端的消息连接# 如果有客户端进行连接,那么accept()函数会返回一个打开的连接与客户端地址connection, client_address = sock.accept()print("连接客户端地址:", client_address)try:# 5.指明一个缓冲区,该缓冲区用来存放recv函数接收到的数据data =connection.recv(1024)print(data)if data:...
tcp_client_socket=socket.socket(socket.AF_INET,socket. SOCK_STREAM) 3.和服务端建立连接 connect(host, port) 表示和服务端套接字建立连接, host是服务器ip地址,port是应用程序的端口号 代码语言:javascript 复制 tcp_client_socket.connect(("127.0.0.1",9090)) 4.发送数据到服务端 send(data) 表示发送数...

Sometimes, the proxy server hides behind an NAT router and doesn't have a public ip. The client side has a public ip "client_ip". Backward proxy feature enables the server to connect backward to client and wait for proxy requests.
