远程执行Powershell命令并使用wmi python打印输出

Question

我想远程执行powershell命令并获取输出。 命令是“（New Object-cMicrosoft.Update.Session).createUpdateSearch（）.Search（“IsInstalled=0”）.Updates |选择标题“。
我试过了

import wmi
try:
  connection = wmi.WMI(ip, user=username, password=password)
  print("connection is established")
  connection.Win32_Process.Create(CommandLine='powershell.exe /c (New-Object -c Microsoft.Update.Session).CreateUpdateSearcher().Search("IsInstalled=0").Updates|Select Title  > C:\output.txt')
except:
  print("connection failed")

Answer 1

你需要注意转义字符。试试这个：

import wmi
try:
  connection = wmi.WMI(ip, user=username, password=password)
  print("connection is established")
  connection.Win32_Process.Create (CommandLine=" powershell.exe -command \" & {New-Object -c Microsoft.Update.Session).CreateUpdateSearcher(). Search(\"IsInstalled=0\").Updates|Select Title}\"  > C:\output.txt")
except:
  print("connection failed")
