2、json文件

{
 "usingComponents": {},
 "onReachBottomDistance": 200
}

3、wXML文件

<!--pages/shoplist/shoplist.wxml-->
<view wx:for="{{result}}" wx:key="ihttp://www.cppcns.comd" class="shop-item">
  <image src="{{item.image}}" class="thumb"></image>
 <view class="shop-item-item">
  <view class="shop-title">商品名:{{item.name}}</view>
  <view>店铺地址:{{item.address}}</view>
  <view>联系电话:{{item.tel}}</view>
 </view>
</view>

4、wxss文件

/* pages/shoplist/shoplist.wxss */
.shop-item{
 display:Flex;
 border: 1rpx solid rgb(216, 194, 194);
 border-radius: 50rpx;
 margin: 15rpx;
 box-shadow: 1rpx 1rpx 15rpx rgb(146, 102, 102);
}
.thumb
{
 width: 320rpx;
 height: 320rpx;
 display: block;
 margin-right: 15rpx;
 padding: 15rpx;
}
.shop-item-item
