微信小程序如何加载数据库真实数据的实现

//获取素材列表接口，该方法位于Application\Home\Controller\WeixinController.class.php中
  public function getdownList(){
    $data=M('Material')->field('id,title,path,date,down,description,view')->order('date desc')->limit(6)->select();
    echo json_encode($data);
  }

/**
   * 生命周期函数--监听页面加载
   */
  onLoad: function () {
    console.log('onLoad')
    var that = this
    wx.request({
      url: 'https://www.100txy.com/weixin/getdownlist', //真实的接口地址
      data: {},
      header: {
        'content-type': 'application/json'
      },
      success: function (res) {
 
        console.log(res.data)
        that.setData({  
          Industry: res.data //设置数据
        })  
      },
      fail: function (err) {
        console.log(err)
      }
    })
  },
