CkPython Requires Chilkat v11.1.0+

Google Maps Geolocation Request

Demonstrates how make a Google Maps Geolocation REST API request. CkPython

#  This example duplicates the following CURL request:
#  curl -d @your_filename.json -H "Content-Type: application/json" -i "https://www.googleapis.com/geolocation/v1/geolocate?key=YOUR_API_KEY"

#  This example requires the Chilkat API to have been previously unlocked.
#  See Global Unlock Sample for sample code.

#  Connect to the Google API REST server.

#  Add the Content-Type request header.

#  Add your API key as a query parameter
rest.AddQueryParam("key","YOUR_API_KEY")

#  The JSON query is contained in the body of the HTTP POST.
#  This is a sample query (which we'll dynamically build in this example)
