我们天天用的http\smtp\ftp等网络协议都是基于socket的上层实现,无论使用何种网络协议,最本质上都是在进行数据的接收和发送,只不过发送的数据类型和内容不同罢了,“发送”和“接收”这两个动作就是socket处理数据的主要方式。 socket起源于Unix,而Unix/Linux基本哲学之一就是“一切皆文件”,都可以用“打开open–> ...

os.path.getsize(filename)gets the size of that file in bytes; that's great, as we need it for showing progress bars in the client and the server. Let's create the TCP socket: # create the client sockets=socket.socket() Copy

The socket is the endpoint of a bidirectional communications channel between the server and the client. Sockets may communicate within a process, between processes on the same machine, or between processes on different machines. For any communication with a remote program, we have to connect through...
