它可以只有一个host,client或者server能够触达彼此。 在中间是循环部分,这里数据在client和server之间通过send()和recv()进行交互。 最最下面,client和server通过close()关闭彼此的sockets。 Echo Client and Server 现在你已经看到了socket API整体的情况以及client和server如何通信,我们创建第一个client和server实现。Ser...

Creating a socket client is simple, a client just connects to the server address and sends data as and when needed. Once all messages are exchanged the connection is closed. Let's see an example: importsocketimporttimeSERVER="192.168.56.1"PORT=9797client=socket.socket(socket.AF_INET,socket.SO...
Today, although the underlying protocols used by the socket API have evolved over the years, and new ones have developed, the low-level API has remained the same. The most common type of socket applications are client-server applications, where one side acts as the server and waits for conne...
socket() bind() listen() accept() 一个listenning socket所做的事情,就像它的名字那样。它监听 来自client的连接。当client尝试连接时,server调用accept()来建立连接。 client调用connect()来建立 一个到server的连接,并 初始化 三次握手。握手的步骤是很重要的,因为握手确保了 连接的两端 在网络中 是可以访问...
