if else based on output of invoke-webrequest in PS

Question

Can someone help me capture only the StatusCode of invoke-webrequest below so that I can determine if a site is up (200) or down (any other code). I think essentially an if

Answer 1

Use property dereferencesmember access operator and if to do the work.

$uri = $args[0]

[Net.ServicePointManager]::SecurityProtocol = ([Net.SecurityProtocolType]::Tls12, [Net.SecurityProtocolType]::Tls11, [Net.SecurityProtocolType]::Tls, [Net.SecurityProtocolType]::Ssl3)

try {
    if ((Invoke-WebRequest $uri -UseBasicParsing -DisableKeepAlive -Method Head).StatusCode -eq 200) {
        Write-Host "The site is up."
    }
    else {
        Write-Host "The site is down."
    }
}
catch {
    Write-Host "The site is down."
}
