微信小程序结合mock.js实现后台模拟及调试

let API_HOST = "http://xxx.com/xxx";
let DEBUG = true;//切换数据入口
var Mock = require('mock.js')
function ajax(data = '', fn, method = "get", header = {}) {
 if (!DEBUG) {
 wx.request({
 url: config.API_HOST + data,
 method: method ? method : 'get',
 data: {},
 header: header ? header : { "Content-Type": "application/json" },
 success: function (res) {
 fn(res);
 }
 });
 } else {
 // 模拟数据
 var res = Mock.mock({
 'error_code': '',
 'error_msg': '',
 'data|10': [{
 'id|+1': 1,
 'img': "@image('200x100', '#4A7BF7','#fff','pic')",
 'title': '@ctitle(3,8)',
 'city': "@county(true)",
 'stock_num': '@integer(0,100)',//库存数量 
 'marketing_start': '@datetime()',
 'marketing_stop': '@now()',
 'price': '@integer(100,2000)',//现价，单位：分 
 'original_price': '@integer(100,3000)'
 }] 
 })
 // 

//index.js
//获取应用实例
var app = getApp()
var API = require('../../utils/api.js')
Page({
 data: {
 },
 onLoad: function () {
 console.log('onLoad')
 var that = this
 // 使用 Mock
 API.ajax('', function (res) {
 //这里既可以获取模拟的res
 console.log(res)
 that.setData({
 list:res.data
 })
 });

 console.log(this.data.list)
 }
})

<!--index.wxml-->
<block wx:for="{{list}}" wx:key="name">
 <view>{{item.title}}</view>
 <text>{{item.city}}</text>
 <view>
 <text>{{item.marketing_start}}</text>
 </view>
 <image src='{{item.img}}'></image>
