(Visual Basic 6.0) Retrieve a Single ContactDemonstrates how to retrieve a single contact (by contactId) 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 Dim jsonToken As New ChilkatJsonObject Dim success As Long success = jsonToken.LoadFile("qa_data/tokens/googleContacts.json") If (success <> 1) Then Debug.Print "Failed to load googleContacts.json" Exit Sub End If Dim gAuth As New ChilkatAuthGoogle gAuth.AccessToken = jsonToken.StringOf("access_token") Dim rest As New ChilkatRest ' Connect using TLS. Dim bAutoReconnect As Long 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 contact, send the following: ' GET /m8/feeds/contacts/default/full/{contactId} ' GData-Version: 3.0 success = rest.AddHeader("GData-Version","3.0") Dim sbPath As New ChilkatStringBuilder success = sbPath.Append("/m8/feeds/contacts/default/full/{contactId}") ' Get the contact having contactId = "7b1c7b6409e718a0" Dim numReplacements As Long numReplacements = sbPath.Replace("{contactId}","7b1c7b6409e718a0") Dim sbResponseBody As New ChilkatStringBuilder success = rest.FullRequestNoBodySb("GET",sbPath.GetAsString(),sbResponseBody) If (success <> 1) Then Debug.Print rest.LastErrorText Exit Sub End If ' A successful response will have a status code equal to 200.
