检索列表的谷歌日历- Zend框架 - Retrieve list of google calendar - Zend Framework

Retrieve list of google calendar - Zend Framework

我刚刚开始使用Zend框架来创建、更新或删除谷歌日历中的事件。目前，我有这段代码，应该检索日历列表，但它不工作。当我运行页面时，它什么也没有显示，只是一个空白页面，甚至没有错误。我尝试打印'echo hello;'，它确实打印了它，但另一个'echo hi;'不再打印了，所以我假设代码在这一行停止工作'$calFeed = $service->getCalendarListFeed();'

谁能告诉我怎么走?由于

 <?php
$path = '/home2/bgolaes/public_html/msnh/ZendGdata/library';
$oldPath = set_include_path(get_include_path() . PATH_SEPARATOR . $path);
// load classes
  require_once 'Zend/Loader.php';
  Zend_Loader::loadClass('Zend_Gdata');
  Zend_Loader::loadClass('Zend_Gdata_ClientLogin');
  Zend_Loader::loadClass('Zend_Gdata_Calendar');
  Zend_Loader::loadClass('Zend_Http_Client');
  // connect to service
  $user = "XXXXX";
  $pass = "XXXXX";
  $service = Zend_Gdata_Calendar::AUTH_SERVICE_NAME;
  $client = Zend_Gdata_ClientLogin::getHttpClient($user, $pass, $service);
try {
  $service = new Zend_Gdata_Calendar($client);
  echo 'hello';
  $calFeed = $service->getCalendarListFeed();
  echo 'hi';
  echo '<h1>' . $calFeed->title->text . '</h1>';
  echo '<ul>';
  foreach ($calFeed as $calendar) {
  echo '<li>' . $calendar->title->text . '</li>';
}
echo '</ul>';
} catch (Zend_Gdata_App_Exception $e) {
}
?>

检索日历列表

$service = Zend_Gdata_Calendar::AUTH_SERVICE_NAME;
$client = Zend_Gdata_ClientLogin::getHttpClient($user, $pass, $service);
$service = new Zend_Gdata_Calendar($client);

try {
    $listFeed= $service->getCalendarListFeed();
} catch (Zend_Gdata_App_Exception $e) {
    echo "Error: " . $e->getMessage();
}
echo "Calendar List Feed";
echo "<ul>";
foreach ($listFeed as $calendar) {
    echo "<li>" . $calendar->title .
         " (Event Feed: " . $calendar->id . ")</li>";
}
echo "</ul>";
