from msilib.schema import Directory
import pysftp
import os
import glob
import fnmatch
from datetime import date, timedelta
 
cnopts = pysftp.CnOpts()

cnopts.hostkeys = None

myHostname = 'sftp.mmm.com'
myUsername = 'uuuu'
myPassword = 'pass'

with pysftp.Connection(host=myHostname, username=myUsername, password=myPassword, cnopts=cnopts) as sftp:
    print("Connection Success")

remotefilepath='/REPORTING/test.zip'

localfilepath='Z:\\data\\sftp_data\\'

sftp.get(remotefilepath,localfilepath)

大家好我一直在使用上面的代码从SFTP提取文件并保存在本地但是我遇到了以下错误

chan = t.open_session( AttributeError：“NoneType”对象没有属性“open_session”

请告知

当with语句结束，打印结束后，连接自动关闭。这就是 with 的用途。更改为简单脚本

sftp = pysftp.Connection(host=myHostname, username=myUsername, password=myPassword, cnopts=cnopts)

或缩进脚本的其余部分，使其位于 with 内：

with pysftp.Connection(host=myHostname, username=myUsername, password=myPassword, cnopts=cnopts) as sftp:
    print("Connection Success")
    remotefilepath='/REPORTING/test.zip'
    localfilepath='Z:\\data\\sftp_data\\'
    sftp.get(remotefilepath,localfilepath)

When the with statement ends, after the print, the connection is automatically closed. That's what with is for. Either change to a simple

sftp = pysftp.Connection(host=myHostname, username=myUsername, password=myPassword, cnopts=cnopts)

or indent the rest of the script so it's inside the with:

with pysftp.Connection(host=myHostname, username=myUsername, password=myPassword, cnopts=cnopts) as sftp:
    print("Connection Success")
    remotefilepath='/REPORTING/test.zip'
    localfilepath='Z:\\data\\sftp_data\\'
    sftp.get(remotefilepath,localfilepath)
