如何在批处理文件中请求管理员访问

I am trying to write a batch file for my users to run from their Vista machines with UAC. The file is re-writing their hosts file, so it needs to be run with Administrator permissions. I need to be able to send them an email with a link to the .bat file. The desired behavior is that when they right-click on the file and say Open, they will get one of those UAC dialogs that makes the screen go dark and forces them to answer whether they want to give the application permission to run as administrator. Instead, they are just seeing "Access denied" on the command line window.

有可能采取不同的做法吗?

这个脚本很有用!只需将其粘贴到bat文件的顶部。如果您想查看脚本的输出，请在批处理文件的底部添加“pause”命令。

更新:这个脚本现在稍微编辑了一下，以支持命令行参数和64位操作系统。

@echo off

:: BatchGotAdmin
:-------------------------------------
REM  --> Check for permissions
    IF "%PROCESSOR_ARCHITECTURE%" EQU "amd64" (
>nul 2>&1 "%SYSTEMROOT%\SysWOW64\cacls.exe" "%SYSTEMROOT%\SysWOW64\config\system"
) ELSE (
>nul 2>&1 "%SYSTEMROOT%\system32\cacls.exe" "%SYSTEMROOT%\system32\config\system"
)

REM --> If error flag set, we do not have admin.
if '%errorlevel%' NEQ '0' (
    echo Requesting administrative privileges...
    goto UACPrompt
) else ( goto gotAdmin )

:UACPrompt
    echo Set UAC = CreateObject^("Shell.Application"^) > "%temp%\getadmin.vbs"
    set params= %*
    echo UAC.ShellExecute "cmd.exe", "/c ""%~s0"" %params:"=""%", "", "runas", 1 >> "%temp%\getadmin.vbs"

    "%temp%\getadmin.vbs"
    del "%temp%\getadmin.vbs"
    exit /B

:gotAdmin
    pushd "%CD%"
    CD /D "%~dp0"
:--------------------------------------    
    <YOUR BATCH SCRIPT HERE>

以下是我一直在用的:

@echo off
if not "%1"=="am_admin" (
    powershell -Command "Start-Process -Verb RunAs -FilePath '%0' -ArgumentList 'am_admin'"
    exit /b
)

echo main code here
pause

注:

Start-Process的-Verb RunAs标志是启用管理提升的标志。只在windows 7和10上测试过，你可能得把引号弄乱目前不支持传递参数，但你可以向-ArgumentList中添加更多的东西。注意-ArgumentList接受单个字符串或字符串数组。

使用mshta提示管理员权限:

@echo off
net session >nul 2>&1 && goto :admintasks
MSHTA "javascript: var shell = new ActiveXObject('shell.application'); shell.ShellExecute('%~nx0', '', '', 'runas', 1);close();"
exit /b
:admintasks
rem ADMIN TASKS HERE

或者，使用powershell:

powershell -c Start-Process "%~nx0" -Verb runas

使用runas命令。但是，我不认为您可以轻松地通过电子邮件发送.bat文件。

你不能从批处理文件中请求管理权限，但是你可以在%temp%中编写一个windows脚本主机脚本并运行它(它反过来以管理员身份执行你的批处理)。使用“runas”作为动词的应用程序对象

还有来自这篇文章的FSUTIL查询，也在ss64.com上有链接，有以下代码:

@Echo Off
Setlocal
:: First check if we are running As Admin/Elevated
FSUTIL dirty query %SystemDrive% >nul
if %errorlevel% EQU 0 goto START

::Create and run a temporary VBScript to elevate this batch file
   Set _batchFile=%~f0
   Set _Args=%*
   :: double up any quotes
   Set _batchFile=""%_batchFile:"=%""
   Set _Args=%_Args:"=""%

   Echo Set UAC = CreateObject^("Shell.Application"^) > "%temp%\~ElevateMe.vbs"
   Echo UAC.ShellExecute "cmd", "/c ""%_batchFile% %_Args%""", "", "runas", 1 >> "%temp%\~ElevateMe.vbs"

   cscript "%temp%\~ElevateMe.vbs" 
   Exit /B

:START
:: set the current directory to the batch file location
cd /d %~dp0
:: Place the code which requires Admin/elevation below
Echo We are now running as admin [%1] [%2]
pause

只要FSUTIL存在，它就是一个可靠的替代方案。
