【问题描述】：
使用 Python 将网络共享映射到 Windows 驱动器的最佳方法是什么？ 此共享还需要用户名和密码。

【问题描述】：
基于@Anon 的建议：
# Drive letter: M
# Shared drive path: \\shared\folder
# Username: user123
# Password: password
import subprocess
# Disconnect anything on M
subprocess.call(r'net use m: /del', shell=True)
# Connect to shared drive, use drive letter M
subprocess.call(r'net use m: \\shared\folder /user:user123 password', shell=True)
我更喜欢这种简单的方法，尤其是在所有信息都是静态的情况下。

我对此设置有疑问。当您尝试在 Web 应用程序中映射驱动器时，驱动器是映射到运行该应用程序的用户还是服务器？
-
使用'net use a: /del /Y'强制，否则会一直挂在请求确认删除
-
另外，如果我们使用 'net use * ' + "\\UNC path\folder" 它会自动找到一个空的驱动器插槽来挂载 "UNC\path\folder"
好的，这是另一种方法...
这个是通过win32wnet之后的。让我知道你的想法...
def mapDrive(drive, networkPath, user, password, force=0):
print networkPath
if (os.path.exists(drive)):
print drive, " Drive in use, trying to unmap..."
if force:
try:
win32wnet.WNetCancelConnection2(drive, 1, 1)
print drive, "successfully unmapped..."
except:
print drive, "Unmap failed, This might not be a network drive..."
return -1
else:
print "Non-forcing call. Will not unmap..."
return -1
else:
print drive, " drive is free..."
if (os.path.exists(networkPath)):
print networkPath, " is found..."
print "Trying to map ", networkPath, " on to ", drive, " ....."
try:
win32wnet.WNetAddConnection2(win32netcon.RESOURCETYPE_DISK, drive, networkPath, None, user, password)
except:
print "Unexpected error..."
return -1
print "Mapping successful"
return 1
else:
print "Network path unreachable..."
return -1
要取消映射，只需使用....
def unmapDrive(drive, force=0):
#Check if the drive is in use
if (os.path.exists(drive)):
print "drive in use, trying to unmap..."
if force == 0:
print "Executing un-forced call..."
try:
win32wnet.WNetCancelConnection2(drive, 1, force)
print drive, "successfully unmapped..."
return 1
except:
print "Unmap failed, try again..."
return -1
else:
print drive, " Drive is already free..."
return -1

使用
win32wnet.WNetAddConnection2和win32wnet.WNetCancelConnection2是个好主意。但是捕获异常并返回返回码似乎是不必要的。内置异常已经为您提供了良好的返回信息。此外，捕捉空的except也不是一个好习惯。
我家里没有服务器可以测试，但也许你可以简单地使用标准库的子进程模块来执行适当的 NET USE 命令？
从 Windows 命令提示符查看 NET HELP USE，看起来您应该能够在 net use 命令中输入密码和用户 ID 来映射驱动器。
在没有映射内容的裸网使用命令的解释器中进行快速测试：
>>> import subprocess
>>> subprocess.check_call(['net', 'use'])
New connections will be remembered.
There are no entries in the list.
0
>>>

假设您导入了必要的库，这是 RPC 服务器的一部分，客户端请求服务器在本地映射驱动器...

【讨论】：
子流程的替代方案：
import os
os.system("net use m: \\\\shared\folder")
或者
import os
cmd = "net use m: \\\\shared\folder"
os.system(cmd)
【讨论】：
我无法让这条线路正常工作：
win32wnet.WNetAddConnection2(win32netcon.RESOURCETYPE_DISK, drive, networkPath, None, user, password)
但是成功了：
win32wnet.WNetAddConnection2(1, 'Z:', r'\UNCpath\share', 无, '登录名', '密码')
【讨论】：
如果您想映射当前登录用户，我认为 subprocess 可以解决您的问题。但是您是否想从一个主帐户控制不同用户的不同映射。您可以从 windows 的注册表中执行此操作
这个想法是加载给定用户的个人资料。
import win32api
import win32security
import win32profile
import win32netcon
import win32net
import win32netcon
import win32con
il = 'G'
m = '\\\\192.168.1.16\\my_share_folder'
usu = 'my_user'
cla = 'passwd'
#login the user
hUser = win32security.LogonUser(
usu,
None,
cla,
win32security.LOGON32_LOGON_NETWORK,
win32security.LOGON32_PROVIDER_DEFAULT
)
#load the profile
hReg = win32profile.LoadUserProfile (
hUser,
{"UserName" : usu}
)
#alter the regedit entries of usu
win32api.RegCreateKey(hReg, "Network")
hkey = win32api.RegOpenKey(hReg, "Network\\", 0, win32con.KEY_ALL_ACCESS)
win32api.RegCreateKey(hkey, il)
hkey = win32api.RegOpenKey(hReg, "Network\\%s" % il, 0, win32con.KEY_ALL_ACCESS)
win32api.RegSetValueEx(hkey, "ConnectionType", 0, win32con.REG_DWORD, 1)
win32api.RegSetValueEx(hkey, "DeferFlags", 0, win32con.REG_DWORD, 4)
win32api.RegSetValueEx(hkey, "ProviderName", 0, win32con.REG_SZ, "Red de Microsoft Windows")
win32api.RegSetValueEx(hkey, "ProviderType", 0, win32con.REG_DWORD, 131072)
