Question

我正在使用Zend_Gdata_Photos PHP客户端访问Google Picasa API，尝试做一些非常简单的事情，列出所有相册，然后列出每张专辑中的所有照片。这是我的代码：

$client = Zend_Gdata_ClientLogin::getHttpClient('*****', '*****', Zend_Gdata_Photos::AUTH_SERVICE_NAME);
$gp = new Zend_Gdata_Photos($client);

$userFeed = $gp->getUserFeed('default');
foreach ($userFeed as $albumEntry) {
 echo "<h2>{$albumEntry->title->text} ({$albumEntry->id->text})</h2>";
 $albumFeed = $gp->getAlbumFeed($albumEntry->id->text);
 foreach ($albumFeed as $photoEntry) {
  echo "{$photoEntry->title->text}<br>";
 }
}

当它运行时，我从$ gp-＆gt; getAlbumFeed（...）行获得此异常：

Zend_Gdata_App_Exception: No root  element

想法是我做错了什么？

好吧，我从来没有想过如何做我想做的事情，但找到了做同样事情的另一种方式：

$query = new Zend_Gdata_Photos_UserQuery();
$userFeed = $gp->getUserFeed(null, $query);
foreach ($userFeed as $albumEntry) {
    $query = new Zend_Gdata_Photos_AlbumQuery();
    $query->setAlbumId($albumEntry->gphotoId->text);
    $albumFeed = $gp->getAlbumFeed($query);
    foreach ($albumFeed as $photoEntry) {
        // ...
    }
}

Zend_Gdata_Photos列出所有专辑和照片
