之前没有加入 channel.get_pty() ，这个一直返回的信息不完整。
官方文档这样描述：get_pty(*args, **kwds)
Request a pseudo-terminal from the server. This is usually used right after creating a client channel, to ask the server to provide some basic terminal semantics for a shell invoked with invoke_shell. It isn’t necessary (or desirable) to call this method if you’re going to exectue a single command with exec_command.
