如何在批处理

Question

我正在尝试使用bat文件检查网址状态

    <# : batch portion
@echo off & setlocal

set "URL=http://l:8080/LevelTwoChargerStartTransaction?chgStationRef=T0001&rfId=0.1.0.255.0.0.0.0."
powershell -noprofile "iex (${%~f0} | out-string)"

goto :EOF

: end batch / begin PowerShell hybrid chimera #>

$request = [Net.WebRequest]::Create($env:URL)
echo $request
$response = $request.GetResponse()
echo $response
$stream = $response.GetResponseStream()
echo $stream
$reader = new-object IO.StreamReader($stream)
echo $reader
[void]$reader.ReadToEnd()

我需要获取URL的状态如何使用批处理文件或其他任何方式执行此操作？
