使用Paramiko在SFTP中的'put'功能

Question

我已经安装并编写了以下Paramiko，但是它无法上传文件。但是它可以轻松地获取文件并在其上执行ls命令。

#set username & password
username='runaway'
password='runaway'
port=22
source= '/Unzip.sh' 
destination ='/var/mpx/www/http'


#SFTP
client.load_system_host_keys()
print " hostname =%s \n username=%s \n password=%s \n" (hostname,username,password)
t = paramiko.Transport((hostname, port)) 
t.connect(username=username,password=password)
sftp = paramiko.SFTPClient.from_transport(t)
sftp.put(source,destination)
#sftp.close()
#t.close()

使用'put'命令会出现以下错误和堆栈跟踪 -

File "upload_file.py", line 84, in ?
    sftp.put(source,destination)
  File "/usr/lib/python2.4/site-packages/paramiko/sftp_client.py", line 522, in put
    fr = self.file(remotepath, 'wb')
  File "/usr/lib/python2.4/site-packages/paramiko/sftp_client.py", line 221, in open
    t, msg = self._request(CMD_OPEN, filename, imode, attrblock)
  File "/usr/lib/python2.4/site-packages/paramiko/sftp_client.py", line 572, in _request
    return self._read_response(num)
  File "/usr/lib/python2.4/site-packages/paramiko/sftp_client.py", line 619, in _read_response
    self._convert_status(msg)
  File "/usr/lib/python2.4/site-packages/paramiko/sftp_client.py", line 649, in _convert_status
    raise IOError(text)
IOError: Failure

我该怎么解决这个问题？

Answer 1

对我来说，这个解决方案看起来非常有趣！

source= '/Unzip.sh' 
destination ='/var/mpx/www/http/Unzip.sh'

刚刚将目标路径修改为包括文件名。 没想到会出现这样的错误，这是Python包的问题。

你也许可以在这方面修补Paramiko ;) 即让它理解目标文件夹。祝好！ - nuts

当你尝试 sftp.mkdir('/exists') 时，这也会发生在2.0.2中：

Traceback (most recent call last):
  ...
  File "/usr/local/lib/python2.7/site-packages/paramiko/sftp_client.py", line 380, in mkdir
    self._request(CMD_MKDIR, path, attr)
  File "/usr/local/lib/python2.7/site-packages/paramiko/sftp_client.py", line 730, in _request
    return self._read_response(num)
  File "/usr/local/lib/python2.7/site-packages/paramiko/sftp_client.py", line 781, in _read_response
    self._convert_status(msg)
  File "/usr/local/lib/python2.7/site-packages/paramiko/sftp_client.py", line 811, in _convert_status
    raise IOError(text)
IOError: Failure

这是我针对Python 2.7.9的修复方案：

try:
    sftp.mkdir(remote_dir)
except IOError:
    logging.debug('%s already exists.', remote_dir)
