用于检查URL状态的PowerShell脚本
我试图监控一组网站链接是否正常运行或没有响应。我在互联网上找到了相同的PowerShell脚本 但是，我需要检查更具体的链接，而不是直接的网站链接，例如：用于检查URL状态的PowerShell脚本,powershell,web-services,powershell-2.0,monitoring,Powershell,Web Services,Powershell 2.0,Monitoring,我试图监控一组网站链接是否正常运行或没有响应。我在互联网上找到了相同的PowerShell脚本 但是，我需要检查更具体的链接，而不是直接的网站链接，例如： http://mypage.global/Chemical/ http://maypage2:9080/portal/site/hotpot/ 当我试图检查这些链接的状态时，我得到以下输出： URL StatusCode StatusDescription ResponseLength TimeTaken http

Invoke WebRequest-Uri的输出https://stackoverflow.com/questions/20259251/powershell-script-to-check-the-status-of-a-urlPS C:\Users\682126> Invoke-WebRequest -Uri https://stackoverflow.com/questions/20259251/powershell-script-to-check-the-status-of-a-url
The term 'Invoke-WebRequest' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

我最近建立了一个脚本来实现这一点 正如David Brabant指出的，您可以使用
System.Net.WebRequest# First we create the request.
$HTTP_Request = [System.Net.WebRequest]::Create('http://google.com')
# We then get a response from the site.
$HTTP_Response = $HTTP_Request.GetResponse()
# We then get the HTTP code as an integer.
$HTTP_Status = [int]$HTTP_Response.StatusCode
If ($HTTP_Status -eq 200) {
Write-Host "Site is OK!"
}
Else {
Write-Host "The Site may be down, please check!"
}
# Finally, we clean up the http request by closing it.
If ($HTTP_Response -eq $null) { }
Else { $HTTP_Response.Close() }
对于使用PowerShell 3或更高版本（即Windows Server 2012+或Windows Server 2008 R2）的用户，您可以使用一行程序来执行此操作，而不是调用
System.Net.WebRequest$statusCode = wget http://stackoverflow.com/questions/20259251/ | % {$_.StatusCode}
function Get-UrlStatusCode([string] $Url)
{
try
{
(Invoke-WebRequest -Uri $Url -UseBasicParsing -DisableKeepAlive).StatusCode
}
catch [Net.WebException]
{
[int]$_.Exception.Response.StatusCode
}
}
$statusCode = Get-UrlStatusCode 'httpstat.us/500'
