我正在使用 Zend Gdata 从 PHP 脚本与 YouTube API 交互。实际上我的工作正常，突然我收到一个关于“Zend_Uri_Exception”的致命错误，消息“提供的 URI 无效”。我该如何纠正异常？
代码：
require_once 'Zend/Loader.php';
Zend_Loader::loadClass('Zend_Gdata_YouTube');
$yt = new Zend_Gdata_YouTube();
$query = $yt->newVideoQuery();
$query->setOrderBy($this->data['ItemVideo']['sort']);
$query->setRacy('include');
$query->setCategory($this->data['ItemVideo']['q']);
try {
$videoFeed = $yt->getVideoFeed($query);
} catch(Exception $e) {
echo var_dump($query) . '<p></p>' . $e;
}
输出：
object(Zend_Gdata_YouTube_VideoQuery)#79 (4) { ["_params:protected"]
=> array(2) { ["orderby"]=> string(9) "relevance" ["racy"]=> string
(7) "include" } ["_defaultFeedUri:protected"]=> NULL
["_url:protected"]=> NULL ["_category:protected"]=> string(14)
"charlie bit me" }
exception 'Zend_Uri_Exception' with message 'Invalid URI supplied' in /
