Demonstrates how to retrieve the full list of contacts for the Google Contacts API.

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

' --------------------------------------------------------------------------------------------------------
' Note: The code for setting up the Chilkat REST object and making the initial connection can be done once.
' Once connected, the REST object may be re-used for many REST API calls.
' (It's a good idea to put the connection setup code in a separate function/subroutine.)
' --------------------------------------------------------------------------------------------------------

' It is assumed we previously obtained an OAuth2 access token.
' This example loads the JSON access token file 
' saved by this example: Get Google Contacts OAuth2 Access Token

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.JsonObject")
set jsonToken = CreateObject("Chilkat.JsonObject")

    outFile.WriteLine("Failed to load googleContacts.json")

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.AuthGoogle")
set gAuth = CreateObject("Chilkat.AuthGoogle")
gAuth.AccessToken = jsonToken.StringOf("access_token")

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Rest")

' Connect using TLS.
bAutoReconnect = 1
success = rest.Connect("www.google.com",443,1,bAutoReconnect)

' Provide the authentication credentials (i.e. the access token)
success = rest.SetAuthGoogle(gAuth)

' ----------------------------------------------
' OK, the REST connection setup is completed..
' ----------------------------------------------

' To retrieve the contacts, we need to send the following:

' 	GET /m8/feeds/contacts/default/full
' 	GData-Version: 3.0

success = rest.AddHeader("GData-Version","3.0")

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.StringBuilder")

success = rest.FullRequestNoBodySb("GET","/m8/feeds/contacts/default/full",sbResponseBody)
If (success <> 1) Then
    outFile.WriteLine(rest.LastErrorText)
    WScript.Quit
End If

' A successful response will have a status code equal to 200.
If (rest.ResponseStatusCode <> 200) Then
    outFile.WriteLine("response status code = " & rest.ResponseStatusCode)
    outFile.WriteLine("response status text = " & rest.ResponseStatusText)
    outFile.WriteLine("response header: " & rest.ResponseHeader)

' in the response body.

' Get the the total number of results, the start index, and the items per page.
' We'll likely NOT get the full list, but will instead get the 1st page.

' We'll borrow a method from FileAccess to get the contactId from the URL string (see the code in the while loop)
' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.FileAccess")

    ' Let's get the URL and parse the contactId from it..
