Intro:
So you now kind of know what powershell scripting is, and there's a better way of scripting via a Microsoft utility included with Windows 7 and newer OSes. You now have even used a parameter in your script so it's re-usable for different machines. What else is available? invoking a web service and displaying the results to the user!
Coding:
I'm rather fond of the parameter based concept for these scripts, methinks I'll use one. I found a handy dandy free soap service on the internet that converts Celsius to Fahrenheit (hey, it could be useful for the metric system users out there). Time to break out a cmd-let called New-WebServiceProxy. As you can see in the following code it's quite easy to invoke a web-service in your script:
param(
[Parameter(Mandatory=$true)][string]$conversionValue
)
$svc = New-WebServiceProxy http://www.w3schools.com/webservices/tempconvert.asmx
$result = $svc.CelsiusToFahrenheit($conversionValue)
write-host "You entered " $conversionValue "degrees celsius and it converted to " $result "degrees fahrenheit"
You basically make a local variable and pass the URL as the parameter to the New-WebServiceProxy. from there you call the variable.MethodName and pass any parameters that might need to be used and store the results in a variable to do what you wish. For our purposes I'll write out the results .
Time to run the script, check out the results:
Huzzah!
