HTTP Alert Sample Scripts

Reading time ~1 minutes

The Cinegy EAS Gateway service supports a simple HTTP protocol for triggering an EAS event. This is provided for easy testing of the system when a physical EAS device is not available.

The below samples of PowerShell scripts demonstrate how to raise and terminate HTTP alerts.

Raise Alert

function Invoke-HTTPMethod($MethodUrl, $Method="GET", $Body="")
{
    $web = new-object net.webclient
    # $web.Headers.add("Accept", "application/json, text/javascript, */*; q=0.01")

    if($Method -eq "GET")
    {
        $web.DownloadString(${MethodUrl})
    }

    if($Method -eq "POST")
    {
        $web.UploadString(${MethodUrl},$Body)
    }
}
$body = "<HTTPAlert TextToDisplay=`"Alert Message Text`" Duration=`"30`"><Audio Mode=`"Synthetic`" TextToSpeech=`"EAS voice alarm!`" /></HTTPAlert>"
Invoke-HTTPMethod -MethodUrl "http://localhost:8090/EASGateway/RaiseAlert" -Method "POST" -Body $body
pause

Stop Alert

function Invoke-HTTPMethod($MethodUrl, $Method="GET", $Body="")
{
    $web = new-object net.webclient
    # $web.Headers.add("Accept", "application/json, text/javascript, */*; q=0.01")

    if($Method -eq "GET")
    {
        $web.DownloadString(${MethodUrl})
    }

    if($Method -eq "POST")
    {
        $web.UploadString(${MethodUrl},$Body)
    }
}

Invoke-HTTPMethod -MethodUrl "http://localhost:8090/EASGateway/StopAlert" -Method "POST" -Body ""
pause
