1. router 相关理解

1.1 vue-router 的理解

  • vue 的一个插件库，专门用来实现 SPA 应用

1.2 对 SPA 应用的理解

  1. 单页 Web 应用（single page web application，SPA）。
  2. 整个应用只有一个完整的页面。
  3. 点击页面中的导航链接不会刷新页面，只会做页面的局部更新。
  4. 数据需要通过 ajax 请求获取。

1.3 路由的理解

  1. 什么是路由?

    • 一个路由就是一组映射关系（key - value）
    • key 为路径, value 可能是 function 或 component
      在这里插入图片描述

  2. 路由分类
    在这里插入图片描述

  • 后端路由：
    • 理解：value 是 function, 用于处理客户端提交的请求。
    • 工作过程：服务器接收到一个请求时, 根据请求路径找到匹配的函数来处理请求, 返回响应数据。
  • 前端路由：
    • 理解：value 是 component，用于展示页面内容。
    • 工作过程：当浏览器的路径改变时, 对应的组件就会显示。

2. 路由的基本使用

  1. 安装vue-router，命令：npm i vue-router
  2. 应用插件：Vue.use(VueRouter)
  3. 编写router配置项:
//引入VueRouter
import VueRouter from 'vue-router'
//引入Luyou 组件
import About from '../components/About'
import Home from '../components/Home'//创建router实例对象，去管理一组一组的路由规则
const router = new VueRouter({routes:[{path:'/about',component:About},{path:'/home',component:Home}]
})//暴露router
export default router
  1. 实现切换（active-class可配置高亮样式）：
    <router-link active-class="active" to="/about">About</router-link>
  2. 指定展示位置：
    <router-view></router-view>

相关 API：

  1. this.$router.push(path): 相当于点击路由链接(可以返回到当前路由界面)
  2. this.$router.replace(path): 用新路由替换当前路由(不可以返回到当前路由界面)
  3. this.$router.back(): 请求(返回)上一个记录路由
  4. this.$router.go(-1): 请求(返回)上一个记录路由
  5. this.$router.go(1): 请求下一个记录路由

总结: 编写使用路由的 3 步

  1. 定义路由组件
  2. 注册路由
  3. 使用路由

3. 几个注意点

  1. 路由组件通常存放在pages文件夹，一般组件通常存放在components文件夹。
  2. 通过切换，“隐藏”了的路由组件，默认是被销毁掉的，需要的时候再去挂载。
  3. 每个组件都有自己的$route属性，里面存储着自己的路由信息。
  4. 整个应用只有一个router，可以通过组件的$router属性获取到。

4. 多级路由

  1. 配置路由规则，使用children配置项：
routes:[{path:'/about',component:About,},{path:'/home',component:Home,children:[ //通过children配置子级路由{path:'news', //此处一定不要写：/newscomponent:News},{path:'message',//此处一定不要写：/messagecomponent:Message}]}
]
  1. 跳转（要写完整路径）：
    <router-link to="/home/news">News</router-link>

5. 路由的 query 参数

  1. 传递参数
<!-- 跳转并携带query参数，to的字符串写法 -->
<router-link :to="/home/message/detail?id=666&title=你好">跳转</router-link><!-- 跳转并携带query参数，to的对象写法 -->
<router-link :to="{path:'/home/message/detail',query:{id:666,title:'你好'}}"
>跳转</router-link>
  1. 接收参数
$route.query.id
$route.query.title

6. 命名路由

  • 作用：可以简化路由的跳转。

6.1 如何使用命名路由

  1. 给路由命名：
{path:'/demo',component:Demo,children:[{path:'test',component:Test,children:[{name:'hello' //给路由命名path:'welcome',component:Hello,}]}]
}
  1. 简化跳转
<!--简化前，需要写完整的路径 -->
<router-link to="/demo/test/welcome">跳转</router-link><!--简化后，直接通过名字跳转 -->
<router-link :to="{name:'hello'}">跳转</router-link><!--简化写法配合传递参数 -->
<router-link :to="{name:'hello',query:{id:666,title:'你好'}}"
>跳转</router-link>

7. 路由的 params 参数

  1. 配置路由，声明接收 params 参数
{path:'/home',component:Home,children:[{path:'news',component:News},{component:Message,children:[{name:'xiangqing',path:'detail/:id/:title', //使用占位符声明接收params参数component:Detail}]}]
}
  1. 传递参数
<!-- 跳转并携带params参数，to的字符串写法 -->
<router-link :to="/home/message/detail/666/你好">跳转</router-link><!-- 跳转并携带params参数，to的对象写法 -->
<router-link :to="{name:'xiangqing',params:{id:666,title:'你好'}}"
>跳转</router-link>

特别注意：路由携带params参数时，若使用to的对象写法，则不能使用path配置项，必须使用name配置！

  1. 接收参数
$route.params.id
$route.params.title

8. 路由的 props 配置

  • 作用：让路由组件更方便的收到参数
{name:'xiangqing',path:'detail/:id',component:Detail,//第一种写法：props值为对象，该对象中所有的key-value的组合最终都会通过props传给Detail组件// props:{a:900}//第二种写法：props值为布尔值，布尔值为true，则把路由收到的所有params参数通过props传给Detail组件// props:true//第三种写法：props值为函数，该函数返回的对象中每一组key-value都会通过props传给Detail组件props(route){return {id:route.query.id,title:route.query.title}}
}

9. <router-link>的 replace 属性

  1. 作用：控制路由跳转时操作浏览器历史记录的模式
  2. 浏览器的历史记录有两种写入方式：分别为push和replace，push是追加历史记录，replace是替换当前记录。路由跳转时候默认为push
  3. 如何开启replace模式：<router-link replace .......>News</router-link>
  4. push 类似与数据结构里面的栈结构，先进后出，replace 是直接替换

10. 编程式路由导航

  • 作用：不借助<router-link> 实现路由跳转，让路由跳转更加灵活
  • 具体编码：
//$router的两个API
this.$router.push({name:'xiangqing',params:{id:xxx,title:xxx}
})this.$router.replace({name:'xiangqing',params:{id:xxx,title:xxx}
})
this.$router.forward() //前进
this.$router.back() //后退
this.$router.go() //可前进也可后退

11. 缓存路由组件

  • 作用：让不展示的路由组件保持挂载，不被销毁。
  • 具体编码：
<keep-alive include="News"> <router-view></router-view>
</keep-alive>

12. 两个新的生命周期钩子

  1. 作用：路由组件所独有的两个钩子，用于捕获路由组件的激活状态。
  2. 具体名字：
    1. activated路由组件被激活时触发。
    2. deactivated路由组件失活时触发。
  • nextTick 是第11个钩子

13. 路由守卫

  • 作用：对路由进行权限控制
  • 分类：全局守卫、独享守卫、组件内守卫

13.1 全局守卫

//全局前置守卫：初始化时执行、每次路由切换前执行
router.beforeEach((to,from,next)=>{console.log('beforeEach',to,from)if(to.meta.isAuth){ //判断当前路由是否需要进行权限控制if(localStorage.getItem('school') === 'atguigu'){ //权限控制的具体规则next() //放行}else{alert('暂无权限查看')// next({name:'guanyu'})}}else{next() //放行}
})//全局后置守卫：初始化时执行、每次路由切换后执行
router.afterEach((to,from)=>{console.log('afterEach',to,from)if(to.meta.title){ document.title = to.meta.title //修改网页的title}else{document.title = 'vue_test'}
})

13.2 独享守卫

beforeEnter(to,from,next){console.log('beforeEnter',to,from)if(to.meta.isAuth){ //判断当前路由是否需要进行权限控制if(localStorage.getItem('school') === 'atguigu'){next()}else{alert('暂无权限查看')// next({name:'guanyu'})}}else{next()}
}

12.3 组件内守卫

//进入守卫：通过路由规则，进入该组件时被调用
beforeRouteEnter (to, from, next) {
},
//离开守卫：通过路由规则，离开该组件时被调用
beforeRouteLeave (to, from, next) {
}

13. 路由器的两种工作模式

  1. 对于一个url来说，什么是hash值？—— #及其后面的内容就是hash值。
  2. hash值不会包含在 HTTP 请求中，即：hash值不会带给服务器。

13.1 hash模式：

  1. 地址中永远带着#号，不美观 。
  2. 若以后将地址通过第三方手机app分享，若app校验严格，则地址会被标记为不合法。
  3. 兼容性较好。

13.2 history模式：

  1. 地址干净，美观 。
  2. 兼容性和hash模式相比略差。
  3. 应用部署上线时需要后端人员支持，解决刷新页面服务端404的问题。
