Vue3---安装路由

介绍

在Vue3项目中安装路由

示例

第一步：执行npm命令安装路由

npm install vue-router@4

第二步：在项目的src文件夹下创建router子文件夹

第三步：创建index.js和routes.js文件，以下为文件的代码

//通过vue-router插件实现模板路由配置
import { createRouter, createWebHashHistory } from 'vue-router'
import { constantRoute } from './routes'
//创建路由器
let router = createRouter({
    //路由模式hash
    history: createWebHashHistory(),
    routes: constantRoute,
    //滚动行为
    scrollBehavior() {
        return {
            left: 0,
            top: 0,
        }
    },
})

export default router

//对外暴露配置路由(常量路由)
export const constantRoute = [
    {
        path: '/',
        redirect: '/login',
        name: 'Default'
    },
    {
        path: '/login',
        component: () => import('@/views/Login.vue'),
        name: 'Login'
    },
    {
        path: '/index',
        component: () => import('@/views/Index.vue'),
        name: 'Index'
    },
    {
        path: '/course',
        component: () => import('@/components/Layout.vue'),
        name: 'Course',
        children: [
            {
                path: 'list',
                component: () => import('@/views/course/CourseList.vue'),
                name: 'CourseList'
            },
            {
                path: 'info',
                component: () => import('@/views/course/CourseInfo.vue'),
                name: 'CourseInfo'
            },
            {
                path: 'play',
                component: () => import('@/views/course/CoursePlay.vue'),
                name: 'CoursePlay'
            },
        ]
    },
    {
        path: '/teacher',
        component: () => import('@/components/Layout.vue'),
        name: 'Teacher',
        children: [
            {
                path: 'list',
                component: () => import('@/views/teacher/TeacherList.vue'),
                name: 'TeacherList'
            },
            {
                path: 'info',
                component: () => import('@/views/teacher/TeacherInfo.vue'),
                name: 'TeacherInfo'
            },
        ]
    },
    {
        path: '/article',
        component: () => import('@/components/Layout.vue'),
        name: 'Article',
        children: [
            {
                path: 'list',
                component: () => import('@/views/article/ArticleList.vue'),
                name: 'ArticleList'
            },
            {
                path: 'info',
                component: () => import('@/views/article/ArticleInfo.vue'),
                name: 'ArticleInfo'
            },
        ]
    },
    {
        path: '/user',
        component: () => import('@/components/Layout.vue'),
        name: 'User',
        children: [
            {
                path: 'center',
                component: () => import('@/views/user/UserCenter.vue'),
                name: 'UserCenter'
            },
        ]
    },
    {
        path: '/404',
        component: () => import('@/views/404.vue'),
        name: '404'
    },
    {
        path: '/:pathMatch(.*)*',
        redirect: '/404',
        name: 'Any'
    }
]

第四步：引入路由，让路由进行工作

import router from './router'
app.use(router)

第四步的完整代码：

// main.js
import { createApp } from 'vue'
import App from './App.vue'

import router from './router'

const app = createApp(App)
app.use(router)
app.mount('#app')
