在Python中,我们可以使用socket模块来创建TCP服务器。下面是一个简单的代码示例: importsocket# 创建TCP服务器server_socket=socket.socket(socket.AF_INET,socket.SOCK_STREAM)# 绑定IP地址和端口号server_socket.bind(('127.0.0.1',8000))# 监听端口号server_socket.listen(5)whileTrue:# 接受客户端连接client_soc...
self.client=self.conn_server() self.active=Truedefconn_server(self): client=socket.socket(socket.AF_INET,socket.SOCK_STREAM) client.setsockopt(socket.SOL_SOCKET,socket.SO_KEEPALIVE,True) err=client.connect_ex(self.ip_port)iferr !=0:print("please check sever's ip_port!")returnNone msg= c...
详细三次握手过程如下: 第一次握手:起初两端都处于CLOSED关闭状态,Client将标志位SYN置为1,随机产生一个值seq=x,并将该数据包发送给Server,Client进入SYN-SENT状态,等待Server确认; 第二次握手:Server收到数据包后由标志位SYN=1得知Client请求建立连接,Server将标志位SYN和ACK都置为1,ack=x+1,随机产生一个值seq...
server_address = ‘localhost’ # 服务器地址 port = 8080 # 端口号 “` 创建TCP客户端对象: “`python client = socket.socket(socket.AF_INET, socket.SOCK_STREAM) “` 4、连接到服务器 使用connect()方法连接到服务器: “`python client.connect((server_address, port)) ...

The SCS framework is a double-way, connection-oriented, and asynchronous communication library. So, after a client connects to the server, they can communicate in both directions (server-to-client or client-to-server) asynchronously until client or server closes the connection. It is not just ...
