vue-router（2）

1. 动态路由匹配

• /home/123456 ---> resFul ---> params
• /home?room_id=123456 ---> query

(1) resFul

(1.1) 通过$route.params获取id

• <div>房间号：{{$route.params.id}}</div>
• <div>成员Id：{{$route.params.mum_id}}</div>

routes: [{
            path:'/home/:id/number/:mum_id',
            name:'home',
            component: Home
        }]

(1.2) 监听

    watch: {
        $route(to,from) {
            console.log(to)
            console.log(from)
        }
    }

（2）query

• 通过$route.query获取query信息
• http://localhost:8080/#/home?room_id=123
• http://localhost:8080/#/home?room_id=123&mum_id=567
• 房间Id：{{$route.query.room_id}}

2. 重定向

    {
        path:'*',
        redirect:'/home'
    }
    {
        path:'*',
        redirect:{name:'home'}
    }
    {
        path:'*',
        redirect(to) {
            if(to.path === '/') {
                return '/home'
            }else {
                return {path:'/err'}
            }
        }
    }

    export default new VueRouter({
        routes: [
            {
                path:'/home/:id?',
                name:'home',
                component: Home
            }
        ],
    
    })
    <template>
        <div>
            <div>我是{{title}}</div>
            <div>房间号：{{$route.params}}</div>
        </div>
    </template>
    <script>
    import Home from '../components/home'
    export default {
        data() {
            return {
                title: 'HOME'
            }
        }
    }
    </script>
