Compared to HTTP, the FTP protocol is much more complicated. Complex reasons because the FTP protocol is used to use two TCP connections, one is a command link to deliver commands between FTP clients and servers; the other is a data link, used to upload or download data. The FTP protocol has two ways of working: Port mode and PASV mode, meaning in Chinese means active and passive. The connection process of the Port is: the client is sent to the server's FTP port (default is 21) Send a connection request, the server accepts the connection, and establish a command link. When you need to transfer data, the client tells the server with the port command on the command link: "I opened XXXX port, and you came over to connect me."
