在Python中通过SFTP(Paramiko)上传文件会产生IOError:失败

标签: python ssh sftp paramiko

目标:我试图通过Python中的Paramiko使用SFTP来上传服务器pc上的文件。

我做了什么:要测试该功能,我使用的是localhost(127.0.0.1)IP。为了实现这一点,我在Stack Overflow建议的帮助下创建了以下代码。

问题:我运行此代码并输入文件名的那一刻,我得到了“IOError:Failure”,尽管处理了该错误。这是错误的快照:

enter image description here

import paramiko as pk
import os

userName = "sk"
ip = "127.0.0.1"
pwd = "1234"
client=""

try:
    client = pk.SSHClient()
    client.set_missing_host_key_policy(pk.AutoAddPolicy())
    client.connect(hostname=ip, port=22, username=userName, password=pwd)

    print '\nConnection Successful!' 

# This exception takes care of Authentication error& exceptions
except pk.AuthenticationException:
    print 'ERROR : Authentication failed because of irrelevant details!'

# This exception will take care of the rest of the error& exceptions
except:
    print 'ERROR : Could not connect to %s.'%ip

local_path = '/home/sk'
remote_path = '/home/%s/Desktop'%userName

#File Upload
file_name = raw_input('Enter the name of the file to upload :')
local_path = os.path.join(local_path, file_name)

ftp_client = client.open_sftp()
try:
    ftp_client.chdir(remote_path) #Test if remote path exists
except IOError:
    ftp_client.mkdir(remote_path) #Create remote path
    ftp_client.chdir(remote_path)

ftp_client.put(local_path, '.') #At this point, you are in remote_path in either case
ftp_client.close()

client.close()

你能指出问题的位置和解决方法吗? 提前谢谢!

SFTPClient.putremotepath)的第二个参数是文件的路径,而不是文件夹。

因此请使用file_name代替'.'

ftp_client.put(local_path, file_name)

...假设您已经在remote_path,就像之前致电.chdir一样。

为了避免需要.chdir,您可以使用绝对路径:

ftp_client.put(local_path, remote_path + '/' + file_name)
