1.1 路由搭建

1.1.1 安装vue router

npm install vue-router@4

1.1.2 在src/router/index.js中创建路由器，并导出

import { createRouter, createWebHistory } from 'vue-router'//导入组件
import LoginVue from '@/views/Login.vue'
import LayoutVue from '@/views/LayoutGeji.vue'//定义路由关系
const routes = [{ path: '/login', component: LoginVue },{ path: '/', component: LayoutVue },
]//创建路由器
const router = createRouter({history: createWebHistory(),routes: routes
})//导出路由
export default router

1.1.3 在vue应用实例中使用vue-router

1.1.4 声明router-view标签，展示组件内容

1.1 自动跳转

import { useRouter } from 'vue-router'const router = useRouter()const login =async ()=>{//调用接口,完成登录let result =  await userLoginService(registerData.value);ElMessage.success(result.msg ? result.msg : '登录成功')//跳转到首页 路由完成跳转router.push('/')
}

1.2 子路由

1.2.1 配置子路由

import { createRouter, createWebHistory } from 'vue-router'//导入组件
import LoginVue from '@/views/Login.vue'
import LayoutVue from '@/views/LayoutGeji.vue'import ArticleCategoryVue from '@/views/article/ArticleCategory.vue'
import ArticleManageVue from '@/views/article/ArticleManage.vue'
import UserAvatarVue from '@/views/user/UserAvatar.vue'
import UserInfoVue from '@/views/user/UserInfo.vue'
import UserResetPasswordVue from '@/views/user/UserResetPassword.vue'//定义路由关系
const routes = [{ path: '/login', component: LoginVue },{path: '/', component: LayoutVue,redirect:'/article/manage', children: [{ path: '/article/category', component: ArticleCategoryVue },{ path: '/article/manage', component: ArticleManageVue },{ path: '/user/info', component: UserInfoVue },{ path: '/user/avatar', component: UserAvatarVue },{ path: '/user/resetPassword', component: UserResetPasswordVue }]}
]//创建路由器
const router = createRouter({history: createWebHistory(),routes: routes
})//导出路由
export default router

1.2.2 声明router-view

1.2.3 为菜单项 el-menu-item 设置index属性，设置点击后的路由路径

```html
<script setup>
import {Management,Promotion,UserFilled,User,Crop,EditPen,SwitchButton,CaretBottom
} from '@element-plus/icons-vue'
