Vue路由结合请求数据 实现新闻列表 新闻详情数据渲染

main.js

import Vue from 'vue';
import App from './App.vue';


//引入公共的scss   注意：创建项目的时候必须用scss

import './assets/css/basic.scss';   




//请求数据


import VueResource from 'vue-resource';
Vue.use(VueResource);




import VueRouter from 'vue-router';

Vue.use(VueRouter);

//1.创建组件


import Home from './components/Home.vue';

import News from './components/News.vue';

import Content from './components/Content.vue';



//2.配置路由   注意：名字

const routes = [
  { path: '/home', component: Home },
  { path: '/news', component: News },

  { path: '/content/:aid', component: Content },   /*动态路由*/

  { path: '*', redirect: '/home' }   /*默认跳转路由*/
]


//3.实例化VueRouter  注意：名字

const router = new VueRouter({
  routes // （缩写）相当于 routes: routes
})




//4、挂载路由

new Vue({
  el: '#app',
  router,
  render: h => h(App)
})


//5 <router-view></router-view> 放在 App.vue

app.vue

<template>


  <div id="app"> 

    <header class="header">

      <router-link to="/home">首页</router-link>
      <router-link to="/news">新闻</router-link>

    </header>

    <hr>

       <router-view></router-view>

  </div>
</template>

<script>


/*1、不同路由传值：动态路由

    1、配置动态路由

       routes: [
        // 动态路径参数 以冒号开头
        { path: '/user/:id', component: User }
      ]


    2、在对应的页面

      this.$route.params获取动态路由的值
