'  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

Dim jsonToken As New Chilkat.JsonObject
Dim success As Boolean = jsonToken.LoadFile("qa_data/tokens/googleContacts.json")
If (success <> True) Then
    Console.WriteLine("Failed to load googleContacts.json")
    Exit Sub
End If


Dim gAuth As New Chilkat.AuthGoogle
gAuth.AccessToken = jsonToken.StringOf("access_token")

Dim rest As New Chilkat.Rest

'  Connect using TLS.
Dim bAutoReconnect As Boolean = True
success = rest.Connect("www.google.com",443,True,bAutoReconnect)

'  Provide the authentication credentials (i.e. the access token)
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?q=<emailAddress>
'  	GData-Version: 3.0

'  Get the contact (or contacts) with this email address:
Dim emailAddressToFind As String = "admin@chilkatsoft.com"

rest.AddHeader("GData-Version","3.0")
rest.AddQueryParam("q",emailAddressToFind)

Dim sbResponseBody As New Chilkat.StringBuilder
success = rest.FullRequestNoBodySb("GET","/m8/feeds/contacts/default/full",sbResponseBody)
If (success <> True) Then
    Console.WriteLine(rest.LastErrorText)
    Exit Sub
End If


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

'  If the 200 response was received, then the contacts XML is contained
'  in the response body.
Dim xml As New Chilkat.Xml
xml.LoadSb(sbResponseBody,False)

'  See below for a sample response body.
xml.SaveXml("qa_output/google_contacts.xml")

'  Now let's parse the XML...

'  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)
Dim fac As New Chilkat.FileAccess

'  Iterate over each contact.
Dim numEntries As Integer = xml.NumChildrenHavingTag("entry")
Dim i As Integer = 0
While i < numEntries
    xml.I = i
    Console.WriteLine((i + 1) & " ----")
    Console.WriteLine("title: " & xml.GetChildContent("entry[i]|title"))

    '  The entry "id" child contains a URL having this format:
    '  <id>http://www.google.com/m8/feeds/contacts/{userEmail}/base/{contactId}</id>

    End If
