使用Python中的PysFTP上传OS.Listdir列出的所有文件到SFTP服务器

Question

我正在尝试从c：/test/文件夹上传文件。 代码：

import pysftp
import os
host = host
port = 22
username = username
password= pass
cnopts = pysftp.CnOpts()
cnopts.hostkeys = None
try:
  conn = pysftp.Connection(host=host,port=port,username=username, password=password, cnopts=cnopts)
  print("connection established successfully")
except:
  print('failed to establish connection to targeted server')
files=os.listdir('C:/Test/')
with conn.cd('/'):
    for file in files:
            try:
                conn.put(file)
                print('uploaded file successfully: ',file)
            except:
                print('failed to upload file: ',file)

我会遇到错误：

“无法上传文件”或“非典型对象没有属性时间”

但此代码可用于一个文件。我在做什么错？

This is Error:
failed to upload file:  Test.pdf
Exception ignored in: <function Connection.__del__ at 0x000001C180B71B40>

os.listdir返回仅文件名。您必须将完整路径传递到 nofollow noreferrer“> pysftpppppppppppppppppppppppppppp Connection。放置 。

如果您不吞噬实际例外，您会很容易地了解到：

Traceback (most recent call last):
  File "test.py", line 19, in <module>
    conn.put(file)
  File "C:\...\Python\Python39\lib\site-packages\pysftp\__init__.py", line 363, in put
    sftpattrs = self._sftp.put(localpath, remotepath, callback=callback,
  File "C:\...\Python\Python39\lib\site-packages\paramiko\sftp_client.py", line 757, in put
    file_size = os.stat(localpath).st_size
FileNotFoundError: [WinError 2] The system cannot find the file specified: 'test.log'  

代码应该是：

localpath = "C:/Test/"
files = os.listdir(localpath)
with conn.cd("/"):
    for file in files:
        if file[-4:]=='.log':
            try:
                conn.put(os.path.join(localpath, file))
                print('uploaded file successfully: ',file)
            except:
                print('failed to upload file: ',file)

或简单地将工作目录更改为源路径：

os.chdir("C:/Test/")
files = os.listdir(".")
with conn.cd("/"):
    for file in files:
        if file[-4:]=='.log':
            try:
                conn.put(file)
                print('uploaded file successfully: ',file)
            except:
                print('failed to upload file: ',file)

义务警告：

• do not de设置<代码> cnopts.hostkeys =无，除非您不关心安全性。有关正确的解决方案，请参见使用pysftp 。

• 尽管这些天，但您不应使用PysFTP，因为它已经死了。直接使用Paramiko。参见 pysftp vs. paramiko 。。
