#Calling a REST WebService
#Use the google maps api to calculate the distance between 2 cities:

PS C:\> $uri = 'https://maps.googleapis.com/maps/api/directions/json'
PS C:\> $query = '?mode=driving&origin=One Microsoft Way, Redmond, WA 98052, United States&destination=Sägereistrasse 29, 8152 Opfikon, Switzerland'
PS C:\> $response = Invoke-RestMethod $uri$query

#The variable $response contains a json object

PS C:\> $response.routes[0].legs[0].distance
text    value
----    -----
35.1 km 35141

PS C:\> $response.routes[0].legs[0].duration
text    value
----    -----
27 mins  1615


#Calling a SOAP Web Service with a typed Client
#NOTE: This API is not available anymore. Use the code as an example.

PS C:\> $uri = 'http://www.webservicex.net/airport.asmx?WSDL'
PS C:\> $airportProxy = New-WebServiceProxy -Uri $uri -Namespace ws
PS C:\> $airportProxy.getAirportInformationByAirportCode('ZRH')

Result:
<NewDataSet>
  <Table>
    <AirportCode>FRA</AirportCode>
    <CityOrAirportName>FRANKFURT INTL</CityOrAirportName>
    <Country>Germany</Country>
…

#We assign the result to a variable of type XML in order to do some further processing:

PS C:\> [XML]$xml = $airportProxy.getAirportInformationByAirportCode('FRA');
PS C:\> $xml.NewDataSet.Table[0].CityOrAirportName
