1. Define a link in any phtml file as
<?php
$client_id= '';
$redirect_uri='test/test/gooledata';
$scope = "https://www.google.com/m8/feeds/"; //google scope to access
$state = "profile"; //optional
$loginUrl = sprintf("https://accounts.google.com/o/oauth2/auth?scope=%s&state=%s&redirect_uri=%s&response_type=code&client_id=%s",$scope,$state,$redirect_uri,$client_id);
?>
Import E-mail Addresses From:<br />
<a href="javascript:poptastic('<?php echo $loginUrl; ?>');">Import</a>
<script>
function poptastic(url) {
var newWindow = window.open(url, 'name', 'height=600,width=450,top=100,left=500');
if (window.focus) {
newWindow.focus();
}
}
function showGmailData(){
//location.reload();
jQuery("#gmailloader").css('display', 'block');
jQuery.ajax({
type: "POST",
data : jQuery("#form-validate").serialize(),
url: '/invitation/index/showgmaildata',
success: function(data) {
jQuery("#gmailloader").css('display', 'none');
result = jQuery.parseJSON(data);
if(!result.success) {
}
else {
}
}
});
}
</script>
2. Define Redirect action in controller
public function googledataAction(){
$authcode= $this->getRequest()->getParam('code');
$importcontacts = array();
if(isset($authcode) && $authcode != ''){
$importcontacts = Mage::helper('test')->importGmailContacts($authcode);
//print_r($importcontacts);
//Mage::getSingleton('core/session')->setImportcontacts($importcontacts);
echo '<html><body>Please wait....<script type="text/javascript">window.opener.showGmailData(); window.close();</script></body></html>';
die();
}
}
3. Define importGmailContacts() method in helper
public function importGmailContacts($authcode){
try{
$clientid='';
$clientsecret='';
$redirecturi='test/test/googledata';
$fields=array(
'code'=> urlencode($authcode),
'client_id'=> urlencode($clientid),
'client_secret'=> urlencode($clientsecret),
'redirect_uri'=> urlencode($redirecturi),
'grant_type'=> urlencode('authorization_code')
);
$fields_string='';
foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
$fields_string=rtrim($fields_string,'&');
//open connection
$ch = curl_init();
//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_URL,'https://accounts.google.com/o/oauth2/token');
curl_setopt($ch,CURLOPT_POST,5);
curl_setopt($ch,CURLOPT_POSTFIELDS,$fields_string);
// Set so curl_exec returns the result instead of outputting it.
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
//to trust any ssl certificates
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
//execute post
$result = curl_exec($ch);
//close connection
curl_close($ch);
//extracting access_token from response string
$response = json_decode($result);
$accesstoken= $response->access_token;
if( $accesstoken!='')
$xmlresponse= file_get_contents('https://www.google.com/m8/feeds/contacts/default/full?max-results=100&oauth_token='. $accesstoken);
//reading xml using SimpleXML
$xml= new SimpleXMLElement($xmlresponse);
$xml->registerXPathNamespace('gd', 'http://schemas.google.com/g/2005');
$result = $xml->xpath('//gd:email');
foreach ($result as $title) {
$importcontact[] = (string)$title->attributes()->address;
}
Mage::getSingleton('core/session')->setImportcontacts($importcontact);
//return $importcontact;
} catch (Exception $e){ echo $e->getMessage();}
}
4.Then use according to requirement in following action
public function showGmailDataAction(){
$result = array(
'success' => false,
'message' => false,
'count' => false,
);
$importcontacts = Mage::getSingleton('core/session')->getImportcontacts();
$this->getResponse()->setBody(Zend_Json::encode($result));
return;
}
