基于vue-cli的vue项目之路由6--重定向3-----method返回重定向路径

设置重定向，肯定是不能写死的，那么应该怎么写“活的”？

1.hello.vue子界面：用来显示的子界面
<template>
	<div class="hello">
		<h1>这个是hello.vue页面</h1>
		<h2></h2>
	</div>
</template>
<script>
	export default {
		name: "hello",
	}
</script>

2.router/index.js：路由配置文件,关键在于第二十七到第三十四行
import Vue from "vue"
import VueRouter from "vue-router"
Vue.use(VueRouter)
const router = new VueRouter({
	routes: [{
			path: "/hello",
			component: require("../components/Hello.vue"),
		},
		{
			path: "/foo",
		component: require("../components/foo.vue"),
		},
		{
			path: "*",
			redirect: to => {
				const {hash,params,query} = to
				if(1) {	return {path: "/foo",}}
				else {return "/hello"}
			}
		}
	]
})
export default router;

3.app.vue:主界面
<template>
	<div id="app">
		<!-- <hello></hello> -->
		<div class="nav">
			<ul>
				<li>
					<router-link to="/hello">hello页面</router-link>
				</li>
				<li>
					<router-link to="/foo">foo页面</router-link>
				</li>
			</ul>
		</div>
		<div class="main">
			<router-view></router-view>
		</div>
	</div>
</template>
<script>
	export default {
		name: "app",
		components: {},
	}
</script>
<style>
	body {background-color: #f8f8ff;font-family: "Avenir", Helvetica, Arial, sans-serif;color: #2c3e50;}
	.nav {position: fixed;width: 108px;left: 40px;}
	.nav ul {list-style: none;margin: 0;padding: 0;}
	.nav ul li {width: 108px;height: 48px;line-height: 48px;border: 1px solid #dadada;text-align: center;	}
	.nav ul li a {display: block;position: relative;text-decoration: none;}
	.nav ul li img {position: absolute;	left: 0;top: 0;	width: 100px;height: 30px;}
	.main {	height: 400px;margin-left: 180px;margin-right: 25px;}
</style>

main.js:配置路由路径
import Vue from "vue"
import App from "./App"
import VueRouter from "vue-router"
import router from "./router"
Vue.use(VueRouter);
new Vue({
	el: "#app",
	router,
	render: h => h(App)
})

效果如下：
