Paramiko get() 引发 IOError “No such file"如果服务器不支持 df -hi [英] Paramiko get() raises IOError "No such file" if server doesn't support df -hi

问题描述

我遇到了 paramiko 的问题，当我尝试从远程服务器获取文件时，它给了我 IOError: [Errno 2] No such file.这是我的代码:

I'm running into a problem with paramiko where it gives me IOError: [Errno 2] No such file when I try to get a file off the remote server. Here's my code:

# set up a transport object t (using an rsa key), which connected successfully
>>> t.is_active()
True
>>> sftp = paramiko.SFTPClient.from_transport(t)
>>> files = sftp.listdir()  # files holds the list ['canceled', 'downloaded', 'FILE.06222012.TXT']
>>> sftp.get(files[2], '.')
IOError: [Errno 2] No such file

但是，当我在命令行上连接到 sftp 时(作为我打开 python repl 的同一用户)，我可以获取文件.有什么想法吗?

However, when I connect to sftp on the command line (as the same user I opened the python repl with) I can get the file. Any ideas?

我发现这篇文章似乎是我遇到的问题https://bugs.launchpad.net/paramiko/+bug/492238 在交互式 sftp 提示中:

I found this post which seems like the issue I'm having https://bugs.launchpad.net/paramiko/+bug/492238 In the interactive sftp prompt:

sftp> df -hi
Server does not support [e-mail] extension

此错误来自 2009 年，并未关闭(但我使用的是最新的 paramiko 1.7.7.1).有人知道解决方法吗?我可以强制 paramiko 只执行与普通 sftp get 等效的操作，而不尝试检查文件完整性吗?

This bug is from 2009 and wasn't closed out (but I'm using the latest paramiko 1.7.7.1). Anyone know of a workaround? Can I force paramiko to just do the equivalent of plain sftp get, without trying to check file integrity?

推荐答案

我遇到了同样的问题，但是我没有因为 sftp 和 df 遇到问题.确保为 localpath 提供正确的文件名！

I had the same issues, however, I did not run into problems because of sftp and df. Make sure to give a proper filename for localpath!

sftp.get(files[2],'file2.txt')
