Vue项目有关路由的使用
用一个简单的示例来进行说明

router.js

项目中的路径都写在该文件中

import Vue from 'vue'
import Router from 'vue-router'
import Login from '@/login'
import UserList from '@/views/user/user/userList'
import UserAdd from '@/views/user/user/userAdd'
import UserEdit from '@/views/user/user/userEdit'
import UserDetail from '@/views/user/user/userDetail'
var router = new Router({
    //mode:'history',
    routes: [
        {
            path: '/login',            //映射路径
            name: 'Login',        //页面titie
            component: Login  //组件实际路径
        },
            {
            path: '/user',
            name: "用户管理",
            redirect: "/user/user/list",//重定向路径，用于指向进入页面时显示哪个页面
            meta: "用户",
            component: mainPage,
            children: [{  //包含子组件
                path: 'user/list',
                name: "用户管理",
                component: UserList
            }, {
                path: 'user/add',
                name: "用户新增",
                component: UserAdd
            },
                {
                    path: 'user/detail/:userId',
                    name: "家庭详情",
                    component: UserDetail
                },
                {
                    path: 'user/detailAdd/:userId',//带参数
                    name: "家庭详情新增",
                    component: UserDetailAdd
                },
                {
                    path: 'user/edit/:userId',
                    name: "用户修改",
                    component: UserEdit
                },

            ]
        },
 ]
});
router.beforeEach((to, from, next) => {
    var userToken = $cookies.get("userToken");
    //to即将进入的目标路由对象，from当前导航正要离开的路由， next  :  下一步执行的函数钩子
    if (to.path === '/login') {// 如果即将进入登录路由，则直接放行
        next();
        return;
    }
    if (userToken) {//userToken是否失效，失效进入登录页面
        next();
    } else {
        next({
            path: '/login',
            query: {redirect: to.fullPath}
        })
    }

路由跳转方法
法1

 this.$router.replace('/');
 或者
   this.$router.push({
        name: `TestVueRouterTo`,
        params: {
          page: '1', code: '8989'
        }
      })

介绍：跳转到指定页面，常与登录连用，在使用时直接调用store的方法，把值存储进去，这样跳转页面就会有各种信息，避免必须手动刷新一下才会显示信息。
调用store.js中方法

this.$store.dispatch('setRouters',JSON.parse(localStorage.getItem("menu")))

法2
不带参数跳转页面

<router-link :to="'/server/menuConfig/menuAdd'">
                    <el-button type="primary">新增菜单</el-button>
                </router-link>

带参数跳转

  <router-link :to="{name:'菜单编辑',params:scope.row}">
                            <el-button type="text" size="small">编辑</el-button>
                        </router-link>

注：params传参 参数不会在路径上显示，但是刷新之后参数会消失
query传参 参数会在路径上显示，刷新之后参数不会会消失
js中
获取路由中参数
this. r o u t e . p a r a m s . p a g e / / q u e r y 传 参 t h i s . route.params.page //query传参 this. route.params.page//query传参this.router.params.page //params传参
