Yii Soap Through Https

I defined a Yii soap server side(reside on remote server) in my Controller,


   public function actions()

    {

        return array(

            'service'=>array(

                'class'=>'CWebServiceAction',

                  'classMap'=>array(

                ),

            ),

        );

    }


/**

     * @param string the symbol of the user_id

     * @return string the return value to the Client application

     * @soap

     */

    public function getClientData($data)

    {

        $user_id = $data;

        return ' user_id = '.$user_id;

    }

Then, I could be able to view this wsdl link in my browser with url https : / / pathtomywsdl. And the browser return me the correct wsdl information.

In my client side(my localhost application). I create a client:


$client = new SoapClient('https : / /pathtomywsdl');

	$result = $client->getClientData('15');

and finnlly I got :

[color="#FF0000"]SoapFault looks like we got no XML document error[/color]

I could do the same function through HTTP.

My question is how could I connect to my soap server through https?

Any ideas?
