(PHP ActiveX) Google Contacts - Retrieve as JSON

Demonstrates how to retrieve Google Contacts as JSON.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

<?php

// 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

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.JsonObject')
$jsonToken = new COM("Chilkat.JsonObject");
$success = $jsonToken->LoadFile('qa_data/tokens/googleContacts.json');
if ($success != 1) {
    print 'Failed to load googleContacts.json' . "\n";
    exit;
}

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.AuthGoogle')
$gAuth = new COM("Chilkat.AuthGoogle");
$gAuth->AccessToken = $jsonToken->stringOf('access_token');

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Rest')
$rest = new COM("Chilkat.Rest");

// Connect using TLS.
$bAutoReconnect = 1;
$success = $rest->Connect('www.google.com',443,1,$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
// 	GData-Version: 3.0

// To get the contacts data in JSON format, set the "alt" query parameter to "json"
$rest->AddQueryParam('alt','json');
$rest->AddHeader('GData-Version','3.0');

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.StringBuilder')
$sbResponseBody = new COM("Chilkat.StringBuilder");
$success = $rest->FullRequestNoBodySb('GET','/m8/feeds/contacts/default/full',$sbResponseBody);
