核心：使用wx:for="{{posts_key}}"，用数组的形式来绑定多个的内容，利用for循环来反复调用后台数据，如果没用用posts_key了，那么对应的item_这种命名就是不可以的！
Wxml
<block wx:for="{{posts_key}}" wx:for-item="item" wx:for-index="idx" wx:key="idx">
<view catchtap="onPostTap" data-postId="{{item.postId}}">
<image src="{{item.images}}"></image>
<text>{{item.content}}</text>
</view>
</block>
JS
var postsData = require(‘../../data/skip-data.js‘)
const app = getApp()
Page({
data: {
},
onLoad:function(options){
this.setData({
posts_key:postsData.postList
});
},
})
Skip-data,js(这个脚本用来模拟本地数据库)
var local_database = [
