Demonstrates how make a Google Maps Geolocation REST API request.

Chilkat ActiveX Downloads

ActiveX for 32-bit and 64-bit Windows

' 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.

Dim rest As New ChilkatRest

' Add the Content-Type request header.
success = rest.AddHeader("Content-Type","application/json")

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

' The JSON query is contained in the body of the HTTP POST.
