socket() bind() listen() accept() connect() connect_ex() send() recv() close() 这些方便使用的接口函数和系统底层的功能调用相一致。 TCP Sockets 我们准备构建一个基于 TCP 协议的socket对象,为什么使用 TCP 呢,因为: 可靠性:如果在传输过程中因为网络原因导致数据包丢失,会有相关机制检测到并且进行重新...
The test server never calls socket.recv(). It just accepts the connection. This causes the network buffers on the server to fill, which eventually raises an error on the client. First, start the server: Shell $ python app-server-test.py 127.0.0.1 65432 Listening on ('127.0.0.1', ...
要使用Python向服务器发送数据,您可以使用HTTP请求或者Socket方式发送数据。下面是两种常用的方法: 使用HTTP请求发送数据: 您可以使用Python内置的requests库来发送HTTP请求。下面是一个示例代码: import requests url = 'http://example.com/api' # 服务器的URL地址 ...
