* 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

loJsonToken = CreateObject('Chilkat.JsonObject')
lnSuccess = loJsonToken.LoadFile("qa_data/tokens/googleContacts.json")
IF (lnSuccess <> 1) THEN
    ? "Failed to load googleContacts.json"
    RELEASE loJsonToken
    CANCEL
ENDIF

loGAuth = CreateObject('Chilkat.AuthGoogle')
loGAuth.AccessToken = loJsonToken.StringOf("access_token")

loRest = CreateObject('Chilkat.Rest')

* Connect using TLS.
lnBAutoReconnect = 1
lnSuccess = loRest.Connect("www.google.com",443,1,lnBAutoReconnect)

* Provide the authentication credentials (i.e. the access token)
loRest.SetAuthGoogle(loGAuth)

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

* To retrieve the contact, send the following:

* 	GET /m8/feeds/contacts/default/full/{contactId}
* 	GData-Version: 3.0

loRest.AddHeader("GData-Version","3.0")

loSbPath = CreateObject('Chilkat.StringBuilder')
loSbPath.Append("/m8/feeds/contacts/default/full/{contactId}")
* Get the contact having contactId = "7b1c7b6409e718a0"
lnNumReplacements = loSbPath.Replace("{contactId}","7b1c7b6409e718a0")

loSbResponseBody = CreateObject('Chilkat.StringBuilder')
lnSuccess = loRest.FullRequestNoBodySb("GET",loSbPath.GetAsString(),loSbResponseBody)
IF (lnSuccess <> 1) THEN
    ? loRest.LastErrorText
    RELEASE loJsonToken
    RELEASE loGAuth
    RELEASE loRest
    RELEASE loSbPath
    RELEASE loSbResponseBody
    CANCEL
ENDIF

* A successful response will have a status code equal to 200.
IF (loRest.ResponseStatusCode <> 200) THEN
    ? "response status code = " + STR(loRest.ResponseStatusCode)
    ? "response status text = " + loRest.ResponseStatusText
    ? "response header: " + loRest.ResponseHeader
    ? "response body: " + loSbResponseBody.GetAsString()
    RELEASE loJsonToken
    RELEASE loGAuth
    RELEASE loRest
    RELEASE loSbPath
    RELEASE loSbResponseBody
    CANCEL
ENDIF

* If the 200 response was received, then the contacts XML is contained
* in the response body.
loXml = CreateObject('Chilkat.Xml')
loXml.LoadSb(loSbResponseBody,0)

* See below for a sample response body.
loXml.SaveXml("qa_output/google_contact.xml")

* Now let's parse the XML...
? "title: " + loXml.GetChildContent("title")

lcEmailAddress = loXml.ChilkatPath("gd:email|(address)")
IF (loXml.LastMethodSuccess = 1) THEN
    ? "email address: " + lcEmailAddress
ENDIF

* The response body XML looks something like this:
