Question

我正在尝试编写一个快速的python脚本来获取一些带有sftp的日志。我的第一个倾向是使用Pysftp，因为它看起来很简单。它工作得很好，直到它有一个更大的文件。我得到一个错误，同时获得大约13 MB的任何文件。然后我决定尝试直接在Paramiko中编写我需要的内容，而不是依赖于额外的Pysftp层。在弄清楚如何做到这一点后，我最终得到了完全相同的错误。这是Paramiko代码，以及我得到的错误的痕迹。有没有人知道为什么这会有拉动任何大文件的问题？感谢。

# Create tranport and connect
transport = paramiko.Transport((host, 22))
transport.connect(username=username, password=password)
sftp = paramiko.SFTPClient.from_transport(transport)

# List of the log files in c:
files = sftp.listdir('c:/logs')
# Now pull them, logging as you go
for f in files:
    if f[0].lower() == 't' or f[:3].lower() == 'std':
      logger.info('Pulling {0}'.format(f))
      sftp.get('c:/logs/{0}'.format(f), output_dir +'/{0}'.format(f))

# Close the connection
sftp.close()
transport.close()

这是错误：

No handlers could be found for logger "paramiko.transport"
