使用 Python 和 WMI 查询获取运行服务列表

Question

我正在尝试获取 windows 机器上运行的服务列表 python。

我的代码：

import wmi
c = wmi.WMI()    
wql = "SELECT * FROM Win32_Service WHERE State = ""Running"""
for x in c.query(wql):
    print(x)

我收到一个错误，我不明白为什么。我的脚本中还有其他一些 wql 语句，它们似乎工作正常。

错误：

Traceback (most recent call last):
  File "C:/Users/i861470/Desktop/Scripts/test.py", line 79, in <module>
    for x in c.query(wql):
  File "C:\Users\i861470\Desktop\Scripts\venv\lib\site-packages\wmi.py", line 1009, in query
    return [ _wmi_object (obj, instance_of, fields) for obj in self._raw_query(wql) ]

Answer 1

wql = "SELECT * FROM Win32_Service WHERE State = ""Running"""

导致无效的 WQL 查询（使用 print(wql) 检查）

SELECT * FROM Win32_Service WHERE State = Running

你需要

wql = 'SELECT * FROM Win32_Service WHERE State = "Running"'

这会导致有效的 WQL 查询（阅读 WHERE Clause 文档）

SELECT * FROM Win32_Service WHERE State = "Running"

顺便说一句，您可以在 WHERE 子句中使用字符串文字，例如 "Running" 或 'Running'。因此，以下 WQL 查询也有效：

wql = "SELECT * FROM Win32_Service WHERE State = 'Running'"
