我正在研究 bash 并在内部使用 PYSFTP 为 SFTP 调用 python 脚本。以前当我使用 FTP 时，有一个 ftp_setdebug(1) 选项，以便我可以检查传输和再见消息。但是对于 SFTP，我找不到任何这样的选项。我发现sftp -vv但究竟需要如何使用它？有没有其他类似FTP的方法？我不想在脚本中包含任何打印语句。

pysftp的API提到您可以log=True在Connection日志中添加一个临时文件。您甚至可以登录到您选择的文件。

它没有提到如果你指定一个数字，即log=1，它将转储到标准输出！

例子：

>>> import pysftp
>>> conn = pysftp.Connection('localhost', 'username', password='password123', log=1)

当然，如果您以非交互方式运行它，则效果相同。

我很困惑log=1所以要澄清：

使用 log 属性并声明一个路径：

import pysftp
conn = pysftp.Connection('localhost', 'usrname', password='pass', log="C:/Users/Fabian/Desktop/logfile.log")
