php 解析302跳转后的链接，莫名其妙的就失效了，求大神看看

            $ch = curl_init();
        curl_setopt($ch,  CURLOPT_RETURNTRANSFER, 0);
        curl_setopt($ch, CURLOPT_URL,  $url);
        curl_setopt($ch,  CURLOPT_FOLLOWLOCATION, 1); // 302 redirect
        $data = curl_exec($ch);
        $Headers =  curl_getinfo($ch);
        curl_close($ch);
        if ($data != $Headers){
                $value=array(
                    'code'=>0,
                    'msg'=>'成功',
                    'url'=>$Headers["url"]
                );
                echo json_encode($value);exit;
        }else{
            $value=array(
                'code'=>-1,
                'msg'=>'链接错误!'
                );
                echo json_encode($value);exit;
            }

$Headers["url"]现在他返回的是原链接。。
