找不到网络名称 - 在 Windows 中复制带有 Python 的文件

Question

我正在尝试将文件从服务器远程复制到正在执行脚本的位置，但是它在连接中返回错误，如果我通过 RDP 从 winodws 建立连接，我正常连接到主持人

script.py

#!/usr/bin/env python
#win32wnetfile.py

import os
import os.path
import shutil
import sys
import win32wnet

def netcopy(host, source, dest_dir, username=None, password=None, move=False):
    """ Copies files or directories to a remote computer. """

    wnet_connect(host, username, password)

    dest_dir = covert_unc(host, dest_dir)

    # Pad a backslash to the destination directory if not provided.
    if not dest_dir[len(dest_dir) - 1] == '\':
        dest_dir = ''.join([dest_dir, '\'])

    # Create the destination dir if its not there.
    if not os.path.exists(dest_dir):
        os.makedirs(dest_dir)
    else:
        # Create a directory anyway if file exists so as to raise an error.
         if not os.path.isdir(dest_dir):
             os.makedirs(dest_dir)

    if move:
        shutil.move(source, dest_dir)
    else:
        shutil.copy(source, dest_dir)

def covert_unc(host, path):
    """ Convert a file path on a host to a UNC path."""
    return ''.join(['\\', host, '\', path.replace(':', '$')])

def wnet_connect(host, username, password):
    unc = ''.join(['\\', host])
    try:
        win32wnet.WNetAddConnection2(0, None, unc, None, username, password)
    except Exception, err:
        if isinstance(err, win32wnet.error):
            # Disconnect previous connections if detected, and reconnect.
            if err[0] == 1219:
                win32wnet.WNetCancelConnection2(unc, 0, 0)
                return wnet_connect(host, username, password)
        raise err

if __name__ == '__main__':

    netcopy('192.168.9.254', 'C:\Program Files (x86)\Data\connect.cfg', 'c:\', 'localdomain\Administrator', 'pw1234')

输出

  File "script.py", line 13, in netcopy
    wnet_connect(host, username, password)
  File "script.py", line 67, in wnet_connect
    raise err
pywintypes.error: (67, 'WNetAddConnection2', 'The network name cannot be found.')

Answer 1

根据[MS.Docs]: WNetAddConnection2W function（强调是我的）：

lpRemoteName

A pointer to a null-terminated string that specifies the network resource to connect to. The string can be up to MAX_PATH characters in length, and must follow the network provider's naming conventions.

所以应该是共享名。我修改了代码以在我的环境中工作（仅一个更改 - 将 netcopy 调用从 netcopy('192.168.9.254', 'C:\Program Files (x86)\Data\connect.cfg', 'c:\', 'localdomain\Administrator', 'pw1234') 替换为 netcopy("127.0.0.1", "C:\c\a.txt", "C$")，因为我连接到 localhost，我在那里有一些共享）。
通知dest_dir值：C$.

输出:

附带说明，在远程计算机上，用户必须具有管理权限，否则写入文件可能会失败并显示 ERROR_ACCESS_DENIED (0x00000005 )，尤其是因为您的目标是 C:。它对我有用，因为我的用户在我的计算机上拥有“上帝之类的”权限。
