python - pysftp 连接更改目录不起作用

Question

我尝试了以下三种更改目录的方法，但它永远不会改变。还有其他人遇到过这个问题吗？

import pysftp
cnopts = pysftp.CnOpts()
cnopts.hostkeys = None
host = 'server1.mydomain.com' # altered
with pysftp.Connection(host=host, **get_credentials(), cnopts=cnopts) as connection:

    connection.execute('cd project')
    print(connection.execute('pwd'))      #---> [b'/home/jm\n']

    connection.execute('cd /home/jm/project')
    print(connection.execute('pwd'))      #---> [b'/home/jm\n']

    connection.cd('project')
    print(connection.execute('pwd'))      #---> [b'/home/jm\n']

    with connection.cd('project'):
        print(connection.execute('pwd'))  #---> [b'/home/jm\n']

'/home/jm/project/' 确实存在。我还尝试了许多其他组合，但我没有在此处列出。

这对我来说没有任何意义，你能帮忙吗？

Answer 1

试试 chdir() 代替。根据文档:

cd(remotepath=None)
context manager that can change to a optionally specified remote directory and restores the old pwd on exit.

chdir(remotepath)
change the current working directory on the remote

所以:

connection.chdir('/home/jm/project')
