为什么我的Ajax没有在php-zend框架中读取json

Hy，有ajax的问题，在zend框架中，ajax调用函数得到发送../funct/param，在极点是corect信息，但是ajax有问题

thanx求助:)这里是php动作代码 -

public function obsadenakartaAction() {

        $parametr = $this->params()->fromRoute('parram', 0);
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET");
        curl_setopt($ch, CURLOPT_URL, 'http://0.0.0.0:5552/getCardInfo?cardSNR=' . $parametr);
        curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
        $data = curl_exec($ch);
        $pole = json_decode($data, TRUE);
        $model = new JsonModel(array('pole'=> $pole));
        return $model;
    }
 in $pole is array
ajax -

$.ajax({

                    type: "GET",
                    url: '/cards/obsadenakarta/5',
                    contentType: "application/json",
                    //data: data //JSON.stringify({ lineFilter: "" });
                })
                .done(function (data)
                {
                    console.log(data);
                    alert(data);

                });

And Error is :
