1.mock.js模拟响应ajax请求?
1.1.mock.js介绍
? Mock.js是一个模拟数据的生成器，用来帮助前端调试开发、进行前后端的原型分离以及用来提高自动化测试效率。
1.2.Mock.js使用步骤?
1.2.1.安装mockjs依赖
npm install mockjs -D
?1.2.2配置开发环境及生产环境
dev.env?
'use strict'
const merge = require('webpack-merge')
const prodEnv = require('./prod.env')
module.exports = merge(prodEnv, {
NODE_ENV: '"development"',
MOCK: 'true'
})
prod.env?
'use strict'
module.exports = {
NODE_ENV: '"production"',
MOCK: 'false'
}
main.js
process.env.MOCK && require('@/mock')
import是ES6标准中的模块化解决方案，require是node中遵循CommonJS规范的模块化解决方案后者支持动态引入，也就是require(${path}/xx.js)
2.mock的使用
2.1.action.js?
/**
* 对后台请求的地址的封装，URL格式如下：
* 模块名_实体名_操作
*/
export default {
'SERVER': 'http://localhost:8080/T216_SSH', //服务器
'SYSTEM_USER_DOLOGIN': '/vue/userAction_login.action', //用户登陆
'SYSTEM_USER_DOREG': '/vue/userAction_reg.action', //用户注册
'SYSTEM_MENU_TREE': '/vue/treeNodeAction.action', //左侧树形菜单加载
'SYSTEM_ARTICLE_LIST': '/vue/articleAction_list.action', //文章列表
'SYSTEM_ARTICLE_ADD': '/vue/articleAction_add.action', //文章新增
'SYSTEM_ARTICLE_EDIT': '/vue/articleAction_edit.action', //文章修改
'SYSTEM_ARTICLE_DEL': '/vue/articleAction_del.action', //文章删除
'SYSTEM_USER_GETASYNCDATA': '/vue/userAction_getAsyncData.action', //vuex中的异步加载数据
'getFullPath': k => { //获得请求的完整地址，用于mockjs测试时使用
return this.SERVER + this[k];
}
}
2.2.login-mock.js?
定义返回的json格式
// const loginInfo = {
// code: -1,
// message: '密码错误'
// }
//使用mockjs的模板生成随机数据
const loginInfo = {
'code|0-1': 0,
'msg|3-10': 'msg'
}
export default loginInfo;
2.3.index.js?
将请求与对应的返回格式进行绑定 ，s1就相当于前端发送对应的请求，而loginInfo就是对应请求返回的数据格式（这里以登录举例，登录无非就两种情况登录成功与登录失败）?
import Mock from 'mockjs' //引入mockjs，npm已安装
import action from '@/api/action' //引入请求地址
//全局设置：设置所有ajax请求的超时时间，模拟网络传输耗时
Mock.setup({
// timeout: 400 //延时400s请求到数据
timeout: 200 - 400 //延时200-400s请求到数据
})
//引登陆的测试数据，并添加至mockjs
import loginInfo from '@/mock/json/login-mock.js'
let s1 = action.getFullPath('SYSTEM_USER_DOLOGIN')
Mock.mock(s1, "post", loginInfo)
// Mock.mock(s1, /post|get/i, loginInfo)
index.js文件的作用很显然,就是将分散的xxx-mock文件集合起来.后面再添加新的mock文件,都需要在这里引入
3.后台主界面搭建
当登录成功时进行页面跳转

在路由中进行配置
import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from '@/components/HelloWorld'
import Login from '@/components/Login.vue'
import Reu from '@/components/Reu.vue'
import AppMain from '@/components/AppMain.vue'
import TopNav from '@/components/TopNav.vue'
import LeftNav from '@/components/LeftNav.vue'
Vue.use(Router)
export default new Router({
routes: [{
path: '/',
name: 'Login',
component: Login,
},
{
path: '/Reu',
name: 'Reu',
component: Reu,
},
{
path: '/AppMain',
name: 'AppMain',
component: AppMain,
children: [{
path: '/TopNav',
name: 'TopNav',
component: TopNav,
},
{
path: '/LeftNav',
name: 'LeftNav',
component: LeftNav,
}
]
}
]
})
4.实现左侧树收缩功能?
总线概念：将一个空的Vue实例放到根组件下，所有的子组件都能调用
总线定义
// 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'
process.env.MOCK && require('@/mock')
import 'element-ui/lib/theme-chalk/index.css' ?
import App from './App'
import router from './router'
import ElementUI from 'element-ui'
import axios from '@/api/http' ?????
import VueAxios from 'vue-axios'
Vue.use(VueAxios,axios)
Vue.use(ElementUI)
Vue.config.productionTip = false
/* eslint-disable no-new */
new Vue({
el: '#app',
data() {
return {
bus:new Vue({
})
}
},
router,
components: { App },
template: '<App/>'
})
通过TopNav.vue组件上的图片按钮控制树形菜单收缩
TopNav.vue
绑定触发事件
当按钮被点击时，图标样式发生改变，同时左侧树形菜单样式发生改变
doToggle(){
this.collapsed=!this.collapsed;
this.$root.bus.$emit("collapsed-aside",this.collapsed);
}LeftNav.vue
?钩子函数监听事件使样式发生变化
根据组件通信原理，将本身样式替换成参数样式
created() {
this.$root.bus.$on("collapsed-aside",(v)=>{
this.collapsed=v;
});?AppMain.vue
created() {
this.$root.bus.$on("collapsed-aside",(v)=>{
this.asideClass=v ?'main-aside-collapsed':'main-aside';
});5.退出功能
点击退出时替换组件
exit(){
this.$router.push({path:'/'})
}
