微信小程序 调用图片轮播API success{} 里该怎么正确实现

wx.request({
url: 'http://192.168.5.153:8016/api/ProductSlideImage/GetList',
data: { productid: p_id },
success(res) {

     var arr = [];
     for (var i = 0; i < res.data.length; i++)
     {
       arr.push(res.data[i].SlideImage);
     }

     that.setData({
       imgUrls: arr
     });
     console.log(arr);
   }
 })

var arr = [];
for (var i = 0; i < res.length; i++)
arr.push(res['slideimage']);
this.setData({
imgUrls: arr
});
