像ftp_setdebug（1）记录消息的Python脚本SFTP调试选项 [英] Debug option for Python SFTP script like ftp_setdebug(1) to log messages

问题描述

我的工作bash和使用PYSFTP内部调用Python脚本为SFTP。 previously当我用FTP有一个ftp_setdebug（1）选项，这样我可以检查传输和再见消息。但对于SFTP，我无法找到任何这样的选择。我发现 SFTP -vv 但如何究竟一是需要使用它？有没有像FTP任何其他方法？我不想在脚本中包含任何打印语句。

I am working on bash and internally calling python Script for SFTP using PYSFTP. Previously when I used FTP there was a ftp_setdebug(1) option so that I can check the Transfer and goodbye messages. But for SFTP I am not able to find any such option. I found sftp -vv but how exactly does one need to use it? Is there any other method like FTP? I don't want to include any print statements in the script.

推荐答案

的 pysftp的API 提到，你可以添加一个日志= TRUE 到连接登录到一个临时文件中。你甚至可以登录到您所选择的文件。

The API of pysftp mentions that you can add a log=True to the Connection to log to a temporary file. You could even log to a file of your choosing.

它没有提到的是，如果你指定一个数字，即登录= 1 ，将转储到stdout！

It doesn't mention though that if you specify a number, i.e. log=1, it will dump to stdout!

例如：

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

作品相同的，如果你运行它非交互的，当然。

Works the same if you run it non-interactively of course.
