Zend Google data API

I was going to implement AuthSub authentication for Ngeblog, when i found that Zend has done it all for me. Zend framework now has GData supported.

As usual, i grabbed it and tasted it a bit. And as you’ve might suspected, sweet!

Here you go, try it out yourself.

set_include_path(dirname(__FILE__) . '/Zend_Gdata');
require_once 'Zend.php';
Zend::loadClass('Zend_Gdata_AuthSub');
Zend::loadClass('Zend_Gdata');
Zend::loadClass('Zend_Feed');

session_start();

if (!isset($_SESSION['blogger_token'])) {
        if (isset($_GET['token'])){
                //convert the single-use token to a session token
                try {
                $session_token =  Zend_Gdata_AuthSub::getAuthSubSessionToken($_GET['token']);
                $_SESSION['blogger_token'] = $session_token;
        } catch ( Exception $e )  {
      echo $e->getMessage();
      exit;
    }
        } else {
                //display link to generate single-use token
                echo 'Click <a href="'. Zend_Gdata_AuthSub::getAuthSubTokenUri('http://'.$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'],"http://beta.blogger.com/feeds",0,1).'">here</a> to authorize this application.';
                exit();
        }
}

if (isset($_GET['logout'])) {
        Zend_Gdata_AuthSub::AuthSubRevokeToken($_SESSION['blogger_token']);
        unset($_SESSION['blogger_token']);
        header('Location: '.$_SERVER['PHP_SELF']);
        exit;
}

echo '<a href=
  "'.$_SERVER['PHP_SELF'].'?logout">Logout</a>'; echo '<hr size="1" />';
try {
  $client = Zend_Gdata_AuthSub::getHttpClient($_SESSION['blogger_token']);
  $gdata = new Zend_Gdata($client);
  $feed = $gdata->getFeed("http://www.blogger.com/feeds/default/blogs");

  foreach ($feed as $item) {
    echo '<h3><a href="'.$item->link("alternate").'">' . $item->title() . '</a></h3>';
    $_id = explode("/",(string) $item->id());
    $blogid = $_id[count($_id)-1];
    $feed1 = $gdata->getFeed("http://www.blogger.com/feeds/$blogid/posts/summary");

    echo "<ul>";
    foreach ($feed1 as $item1) {
      echo "<li>";
      echo "<a href=\"{$item1->link('alternate')}\">{$item1->title()}</a><br />";
      echo "{$item1->summary()}<br />";
      echo "</li>";
    }
    echo "</ul>";
  }
} catch ( Exception $e )  {
  echo $e->getMessage();
}

  1. Hi,
    I’ve been trying to integrate my mobile application to post to blogger. I tried playing with your script which helped me understand a lot about how it works. In fact i learnt more from here than from the actual google explanation.

    I’m not having luck though, because i’m not a very technical person. So finally i have to ask “would be interested in helping me out?”
