mockjs应用在VUE设计中的尝试

关于mockjs,官网描述的是

1.前后端分离

2.不需要修改既有代码,就可以拦截 Ajax 请求,返回模拟的响应数据。

3.数据类型丰富

4.通过随机数据,模拟各种场景。

总结起来就是在后端接口没有开发完成之前,前端可以用已有的接口文档,在真实的请求上拦截ajax,并根据mockjs的mock数据的规则,模拟真实接口返回的数据,并将随机的模拟数据返回参与相应的数据交互处理,这样真正实现了前后台的分离开发。

与以往的自己模拟的假数据不同,mockjs可以带给我们的是:在后台接口未开发完成之前模拟数据,并返回,完成前台的交互;在后台数据完成之后,你所做的只是去掉mockjs:停止拦截真实的ajax,仅此而已。

在项目中尝试了mockjs,mock数据,实现前后端分离开发。

1.安装vue-cli全局脚手架

npm install –global vue-cli

2.创建vue项目

vue init webpack mockjs
cd mockjs
npm install axios –save

3.安装mockjs

npm install mockjs –save-dev

在安装过程中我出现了以下问题

npm install stylus-loader 警告

需要另外一个组件支持,

npm install –save stylus stylus-loader

这样搭建好VUE,项目目录如下:

axios/api 用来封装axios

Hello.vue 页面首页

NeswCell.vue 新闻组件

router/index.js 路由

main.js 入口js

mock.js mockjs文件

5.在入口js里引入mockjs

// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
import App from './App'
import router from './router'

Vue.config.productionTip = false

// 引入mockjs
require('./mock.js')

/* eslint-disable no-new */
new Vue({
el: '#app',
router,
template: '<App/>',
components: {
App
}
})

Vue.filter('getYMD', function(input) {
return input.split(' ')[0];
})

6. 添加一个mock规则

// 引入mockjs
const Mock = require('mockjs');
// 获取 mock.Random 对象
const Random = Mock.Random;
// mock一组数据
const produceNewsData = function() {
let articles = [];
for (let i = 0; i < 100; i++) {
let newArticleObject = {
title: Random.csentence(5, 30), // Random.csentence( min, max )
thumbnail_pic_s: Random.dataImage('300x250', 'mock的图片'), // Random.dataImage( size, text ) 生成一段随机的 Base64 图片编码
author_name: Random.cname(), // Random.cname() 随机生成一个常见的中文姓名
date: Random.date() + ' ' + Random.time() // Random.date()指示生成的日期字符串的格式,默认为yyyy-MM-dd;Random.time() 返回一个随机的时间字符串
}
articles.push(newArticleObject)
}

return {
articles: articles
}
}

// Mock.mock( url, post/get , 返回的数据);
Mock.mock('/news/index', 'post', produceNewsData);

7. 在Hello.vue 中请求文档接口,并接收mock数据

<!-- Add "scoped" attribute to limit CSS to this component only -->
