我在这里读到:
https://router.vuejs.org/en/essentials/dynamic-matching.html
但它似乎没有让我匹配说:
/mycoolapp?someid=123
是的,我能做到
/mycoolapp/123
但这不是问题
问题是:我可以使用get query参数动态匹配路由吗?
答案 0 :(得分:5)
您可以通过someid
在示例$route.query.someid
中访问查询参数。 From $route
docs:
<强>
$route.query
强>输入:
Object
包含查询字符串的键/值对的对象。对于 例如,对于路径
/foo?user=1
,我们得到$route.query.user == 1
。如果 没有查询该值将是一个空对象。
演示如下:
const UserList = {
template: '#users',
data() { return { users: [] } },
created() {
axios.get('https://jsonplaceholder.typicode.com/users').then(r => this.users = r.data);
}
};
const User = {
props: ['uid', 'user'],
template: '#user'
}
var router = new VueRouter({
routes: [{
path: '/',
component: UserList
},
{
path: '/user/:uid',
component: User,
name: 'user',
props: true
}]
});
var app = new Vue({
el: '#app',
router: router,
template: '<router-view></router-view>'
});
<script src="https://unpkg.com/vue"></script>
<script src="https://unpkg.com/vue-router"></script>
<script src="https://unpkg.com/axios/dist/axios.min.js"></script>
<template id="users" functional>
<div>
<ul>
<li v-for="user in users">
<div>
{{ user.name }} -
<router-link :to="{name: 'user', params: {uid: user.id, user: user}, query: {field: 'email'}}">(email)</router-link> -
<router-link :to="{name: 'user', params: {uid: user.id, user: user}, query: {field: 'website'}}">(website)</router-link>
</div>
</li>
</ul>
</div>
</template>
<template id="user" functional>
<div class="row">
<b>{{ user.name }}</b><br>
{{ $route.query.field }}: {{ user[$route.query.field] }}<br>
<router-link :to="{path: '/'}">back</router-link>
</div>
</template>
<div id="app">
<p>{{ message }}</p>
</div>
另一方面,如果要根据查询参数重定向到特定组件,可以使用navigation guards。例如,beforeEach
:
router.beforeEach((to, from, next) => {
if (to.query.field === 'email') {
next({path: '/email'}); // some hypothetical path
} else {
next();
}
});
