Demonstrates how to download Google Contact's photo.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows

; 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

$oJsonToken = ObjCreate("Chilkat.JsonObject")
Local $bSuccess = $oJsonToken.LoadFile("qa_data/tokens/googleContacts.json")

    Exit
EndIf

$oGAuth = ObjCreate("Chilkat.AuthGoogle")
$oGAuth.AccessToken = $oJsonToken.StringOf("access_token")

$oRest = ObjCreate("Chilkat.Rest")

; Connect using TLS.
Local $bAutoReconnect = True
$bSuccess = $oRest.Connect("www.google.com",443,True,$bAutoReconnect)

; Provide the authentication credentials (i.e. the access token)
$oRest.SetAuthGoogle($oGAuth)

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

; To get the photo, send the following:

; 	GET /m8/feeds/photos/media/default/contactId

$oRest.AddHeader("GData-Version","3.0")

$oSbPath = ObjCreate("Chilkat.StringBuilder")
; Get the photo for the contact having contactId = "1ea2e4fe0ef24e09"

; A 404 response indicates the contact has no photo.
; (We could've first fetched the contact information, parsed out the 
; photo etag, and then if no photo etag existed, we'd know the contact has no
; photo.  Or... we can just try to download the photo and if a 404 is received,
; we know there's no photo.  Much simpler.)

    ; does not contain image data.  Instead it contains XML.
