我在Windows 7下在Python中使用WMI（通过win32com）遇到了一个棘手的问题。我一直无法找到解决方案。在Windows 7下，Python WMI调用不起作用
这里是我的代码：
from win32com.client import GetObject
def get_printers(computer):
""" Get a list of printers from the specified computer name. """
wmiservice = GetObject(r"winmgmts:{impersonationLevel=impersonate}!\\" + computer + r"\root\cimv2")
return wmiservice.ExecQuery("Select * from Win32_Printer")
for printer in get_printers("ps2"):
print printer.Name
这在Windows XP下的伟大工程。但失败草草收场，如果我在Windows 7下运行这个命令：
Traceback (most recent call last):
File "C:\Python27\Lib\site-packages\Pythonwin\pywin\framework\scriptutils.py", line 325, in RunScript
exec codeObject in __main__.__dict__
File "C:\Python27\sample\temp2.py", line 8, in <module>
for printer in get_printers("ps2"):
File "C:\Python27\sample\temp2.py", line 5, in get_printers
wmiservice = GetObject(r"winmgmts:{impersonationLevel=impersonate}!\\" + computer + r"\root\cimv2")
File "C:\Python27\lib\site-packages\win32com\client\__init__.py", line 72, in GetObject
return Moniker(Pathname, clsctx)
File "C:\Python27\lib\site-packages\win32com\client\__init__.py", line 87, in Moniker
moniker, i, bindCtx = pythoncom.MkParseDisplayName(Pathname)
com_error: (-2147024891, 'Access is denied.', None, None)
我都试过了，我可以在Win 7想起：禁用防火墙（无病毒扫描仪），确保DCOM已启用，确保WMI已启用，禁用UAC 。任何帮助将非常感激。
注意：我在Windows 7 Ultimate x86（和Windows XP SP3）下使用Python 2.7.1和pywin32 build 215。
