      $jsApi = new \JsApi_pub(); 
       
      //=========步骤1:网页授权获取用户openid============
      if (!isset($_GET['code']))
      {
        //触发微信返回code码
        $url = $jsApi->createOauthUrlForCode(\WxPayConf_pub::JS_API_CALL_URL.'/order_id/'.$param['order_id']);
        Header("Location: $url");
      }else
      {
        $order_id = $param['order_id'];
        $info = M('Order')->where('id='.$order_id)->find();

          dump('该订单不存在或已支付'.$order_id);

        $a = $info['money'];
        $b = 100;
        $c = $a * $b;
         
        //获取code码,以获取openid

//       $out_trade_no = \WxPayConf_pub::APPID."$timeStamp";
      $out_trade_no = $info['ordersn'];
      $unifiedOrder->setParameter("out_trade_no", "$out_trade_no");//商户订单号

      $prepay_id = $unifiedOrder->getPrepayId();
      //=========步骤3:使用jsapi调起支付============
      $jsApi->setPrepayId($prepay_id);
      $jsApiParameters = $jsApi->getParameters();
      $this->assign('jsApiParameters', $jsApiParameters);
