◆ vue-router页面地址路由、vue钩子拦截登录状态：

/*
 *  页面地址路由js
 */
import Vue from 'vue'
import _router from 'vue-router'
import store from '../vuex'

Vue.use(_router) //应用路由

const router = new _router({
    routes: [
        // 登录、注册
        {
            path: '/login',
            component: resolve => require(['../views/auth/login'], resolve),
        },
        {
            path: '/register',
            component: resolve => require(['../views/auth/register'], resolve),
        },

        // 首页、通讯录、我
        {
            path: '/',
            component: resolve => require(['../views/index'], resolve),
            meta: { showHeader: true, showTabBar: true, requireAuth: true }
        },
        {
            path: '/contact',
            component: resolve => require(['../views/contact'], resolve),
            meta: { showHeader: true, showTabBar: true, requireAuth: true },
        },
        {
            path: '/contact/uinfo',
            component: resolve => require(['../views/contact/uinfo'], resolve),
        },
        {
            path: '/ucenter',
            component: resolve => require(['../views/ucenter'], resolve),
            meta: { showHeader: true, showTabBar: true, requireAuth: true }
        },
        // 聊天页面
        {
            path: '/chat/group-chat',
            component: resolve => require(['../views/chat/group-chat'], resolve),
            meta: { requireAuth: true }
        },
        {
            path: '/chat/single-chat',
            component: resolve => require(['../views/chat/single-chat'], resolve),

            meta: { requireAuth: true }
        }

        // ...
    ]
})

// 注册全局钩子拦截登录状态
const that = this
router.beforeEach((to, from, next) => {
    const token = store.state.token
    // 判断该路由地址是否需要登录权限
    if(to.meta.requireAuth){
        // 通过vuex state获取当前token是否存在
        if(token){
            next()
        }else{
            // console.log('还未登录授权！')
            next()
            wcPop({
                content: '还未登录授权！', style: 'background:#e03b30;color:#fff;', time: 2,
                end: function(){
                    next({ path: '/login' })
                }
            });
        }
    }else{
        next()
    }
})

export default router

◆ 引入第三方组件库、插件：

// >>>引入js
import $ from 'jquery'
import fontsize from './assets/js/fontsize'

// >>>引入弹窗插件
import wcPop from './assets/js/wcPop/wcPop'
import './assets/js/wcPop/skin/wcPop.css'

// >>>引入饿了么移动端vue组件库
import MintUI, { Loadmore } from 'mint-ui'
import 'mint-ui/lib/style.css'
Vue.component(Loadmore.name, Loadmore)
Vue.use(MintUI)

// >>>引入图片预览插件
import photoPreview from 'vue-photo-preview'
import 'vue-photo-preview/dist/skin.css'
Vue.use(photoPreview, {
  loop: false,
  fullscreenEl: false, //是否全屏
  arrowEl: false, //左右按钮
})

// >>>引入地址路由
import router from './router'
import store from './vuex'
