vue-router 提供了两种形式的传参风格：
传统风格(?k0=v0&k1=v1)、Restful风格(/:key)
传统风格的参数存放再query中，Restful风格的参数存放再params中
传统风格
示例URL：http://127.0.0.1:5173/user?userid=123&username=张三
使用传统风格，src/router/index.js无需调整，内容如下：
import {
createRouter, createWebHashHistory } from 'vue-router'
import Main from '../views/Main.vue'
import User from '../views/User.vue'
import NotFound from '../views/NotFound.vue'
const routes = [
{
path: '/',
name: 'Main',
component: Main
},
{
path: '/user',
name: 'User',
component: User,
},
{
path: '/:path(.*)', component: NotFound },
]
const router = createRouter({
history: createWebHashHistory(),
routes
})
export default router
配置路由参数
// App.vue
<template>
<router-link to="/user?userid=123&username=张三">go User Page</router-link>
<router-link :to="{path:'/user', query:{username:'张三', userid:123}}">go User Page</router-link>
// 推荐
<router-link :to="{name:'User', query:{username:'张三', userid:123}}">go User Page</router-link>
<router-view></router-view>
</template>
在User.vue中获取参数
// 组合式
<script setup>
import {
useRoute } from 'vue-router'
const route = useRoute()
const userid = route.query.userid
const username = route.query.username
</script>
// 选项式
<script>
export default {
data() {
return {
userid: '',
username: ''
}
},
mounted() {
this.userid = this.$route.query.userid
this.username = this.$route.query.username
},
}
</script>
Restful 风格传参
示例URL：http://127.0.0.1:5173/user/123/张三
修改src/router/index.js，如下：
import {
createRouter, createWebHashHistory } from 'vue-router'
import Main from '../views/Main.vue'
import User from '../views/User.vue'
import NotFound from '../views/NotFound.vue'
const routes = [
{
path: '/',
name: 'Main',
component: Main
},
{
path: '/user/:userid/:username',
name: 'User',
component: User,
},
{
path: '/:path(.*)', component: NotFound },
]
const router = createRouter({
history: createWebHashHistory(),
routes
})
export default router
配置路由参数
// App.vue
<template>
<router-link to="/user/123/张三">go User Page</router-link>
// 下面的方式不可用
// [Vue Router warn]: Path "/user" was passed with params but they will be ignored. Use a named route alongside
// params instead.
<router-link :to="{path:'/user', params:{username:'张三', userid:123}}">go User Page</router-link>
// 推荐
<router-link :to="{name:'User', params:{username:'张三', userid:123}}">go User Page</router-link>
<router-view></router-view>
</template>
在User.vue中获取参数
// 组合式
<script setup>
import {
useRoute } from 'vue-router'
const route = useRoute()
const userid = route.params.userid
const username = route.params.username
</script>
// 选项式
<script>
export default {
data() {
return {
userid: '',
username: ''
}
},
mounted() {
this.userid = this.$route.params.userid
this.username = this.$route.params.username
},
}
</script>
以上两种传参方式，学会以后基本可以完成项目
拓展
通过映射的方式将传参映射成props,默认只映射params中的参数，实现如下：
修改src/router/index.js
const routes = [
{
path: '/',
name: 'Main',
component: Main
},
{
path: '/user/:userid/:username',
name: 'User',
component: User,
// 添加
props: ture
},
{
path: '/:path(.*)', component: NotFound },
]
开启映射开关后，同时需要在跳转页面中的props中进行接收
// 组合式
<script setup>
import {
useRoute } from 'vue-router'
defineProps({
userid: String,
username: String
})
</script>
//选项式
<script>
export default {
props: {
userid: String,
username: String
}
}
</script>
也可以将query中的参数进行映射，稍微麻烦点，如下：
// src/router/index.js
const routes = [
{
path: '/',
name: 'Main',
component: Main
},
{
path: '/user',
name: 'User',
component: User,
// 添加
// props: ture
// 这里我是直接将query 给映射过去了，当然如果你只有一个参数的话，你也可以
// props: route => ({ userid: route.query.userid })
props: route => ({
query: route.query })
},
{
path: '/:path(.*)', component: NotFound },
取值如下:
// User.vue
<template>
<h2>User Page</h2>
<div>{
{ query.userid }}</div>
<div>{
{ query.username }}</div>
</template>
// 组合式
<script setup>
defineProps({
query: {
type: Object,
default() {
return {
}
}
}
})
</script>
// 选项式
<script>
export default {
props: {
query: {
type: Object,
default() {
return {
};
}
}
}
}
</script>
除了上述的传参方式，还可以使用共享全局变量、Cookie、localStorage的方式，有兴趣的小伙伴可以试试
