PowerShell Webservices Probe

The following script reads URL’s from an array to check if specific web services are online. When the script finds that one or more services are offline it sends an e-mail message (HTML). A TEXT version of the message is created in the Windows EventLog.

Het script uses custum functions: fnSendMail en fnWriteEventLog om berichten af te handelen.

PowerShell WebService Calls

Performing a SOAP web service call using PowerShell. The methods can be requested by means of the command: $oWebSvc1 | Get-Member.

#WebService values...
[string]$sWebSvcWSDL = "https://host.domain.fqdn/Webservice1?wsdl"
[string]$sPostValue1 = "Waarde"
[string]$sPostValue2 = $true

#Create webservice object...
$oWebSvc1 = New-WebServiceProxy -Uri $sWebSvcWSDL

#POST values w. result in een object...
$oResult1 = $oWebSvc1.method1($sPostValue1, $sPostValue2)

#POST values w. result to RAW XML...
[xml]$xResult = $oWebSvc1.method1($sPostValue1, $sPostValues2) | ConvertTo-Xml
$xResult.get_OuterXML() | Out-File C:\Pad\Naar\Bestand.xml
