Chilkat Xojo Plugin Download

Xojo Plugin for Windows, Linux, Mac OS X, and ARM

//  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
success = jsonToken.LoadFile("qa_data/tokens/googleContacts.json")
If (success <> True) Then
    System.DebugLog("Failed to load googleContacts.json")
    Return
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
bAutoReconnect = True
success = rest.Connect("www.google.com",443,True,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?q=<emailAddress>
//  	GData-Version: 3.0

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

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

success = rest.FullRequestNoBodySb("GET","/m8/feeds/contacts/default/full",sbResponseBody)
If (success <> True) Then
    System.DebugLog(rest.LastErrorText)
    Return
End If

//  A successful response will have a status code equal to 200.
If (rest.ResponseStatusCode <> 200) Then
    System.DebugLog("response status code = " + Str(rest.ResponseStatusCode))
    System.DebugLog("response status text = " + rest.ResponseStatusText)

//  in the response body.
Dim xml As New Chilkat.Xml
success = xml.LoadSb(sbResponseBody,False)

//  See below for a sample response body.
success = 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.

System.DebugLog("startIndex = " + Str(startIndex))
System.DebugLog("itemsPerPage = " + Str(itemsPerPage))

//  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 Int32
numEntries = xml.NumChildrenHavingTag("entry")
