php – 与Yii混合使用auth导致重定向循环

我在打电话

$hybridauth = new Hybrid_Auth( Yii::app()->params['hybridauth'] );
$adapter = $hybridauth->authenticate( 'Twitter');

但由于某种原因,它重定向到http：// localhost / yiiauth / authtest /？hauth.start = Twitter& hauth.time = 1350973441,这会导致重定向循环.
有什么方法可以解决这个问题吗？我的混合身份验证配置如下：

'params'=>array(

    'hybridauth'=>array(
        "base_url" => "http://localhost/yiiauth/authtest/","providers" => array ( 
            "Twitter" => array ( 
                "enabled" => true,"keys"    => array ( "key" => "mykey","secret" => "mysecret" ) 
            ),),"debug_mode" => false,"debug_file" => "",)
),

我的hybridauth文件在/ protected / extensions / hybridauth中,我在index.PHP文件的顶部包含了Hybrid / Auth.PHP
