How to check if Paramiko successfully uploaded a file to an SFTP server?

阅读更多关于 How to check if Paramiko successfully uploaded a file to an SFTP server?

问题 I use Paramiko to put a file to an SFTP server: import paramiko transport = paramiko.Transport((host, port)) transport.connect(username=username, password=password) sftp = paramiko.SFTPClient.from_transport(transport) sftp.put(local_path, remote_path) Now, I would like to check if it worked. The idea is that I compare the checksum of the local file and the remote one (that is located on the SFTP server). Does Paramiko functionality allows to do that? If it is the case, how exactly it works?

I have seen things like this: # Wait for the command to finish while not stdout.channel.exit_status_ready(): if stdout.channel.recv_ready(): stdoutLines = stdout.readlines() But that seems to sometimes never run the readlines() (even when there is supposed to be data on stdout). What that seems to mean to me is that stdout.channel.recv_ready() is not necessarily ready (True) as soon as stdout.channel.exit_status_ready() is True. Is
