Mys*_*dev 5 javascript vue-router vuejs3 pinia
我无法从商店访问我的路线。对此或许有一个很好的解释。我使用 Vuejs3 和 Pinia
我的商店:
import {defineStore} from 'pinia'
import {useRoute} from "vue-router";
type navigationState = {
selectedNavigationItem: INavigationItem | null,
selectedNavigationPage: INavigationPage | null,
}
export const useNavigationStore = defineStore('navigationStore', {
state: () => ({
/**
* when the user clicks on an element of the navbar we store the navigation item here
*/
selectedNavigationItem: null,
/**
* when the user clicks on an element of the sidebar we store the navigation page here
*/
selectedNavigationPage: null,
} as navigationState),
actions: {
/**
* Set Selected navigation page
* @param navigationPage
* @type INavigationPage
*/
setSelectedNavigationPage(navigationPage: INavigationPage | null) {
console.log(useRoute())
this.selectedNavigationPage = navigationPage
},
},
})

当我像 setSelectedNavigationPage 方法中那样执行控制台日志时
我有一个未定义的
刚刚发现我们有不同的方式来定义Store:Setup Stores
// src/stores/user.js
import { defineStore } from 'pinia'
import { useRoute, useRouter } from 'vue-router'
import api from './api.js'
export const useUserStore = defineStore('User', () => { // use function
const route = useRoute()
const router = useRouter()
const login = async () => {
await api.POST('login', {username, password})
router.replace({name: 'home'})
}
return { login } // IMPORTANT: need to return anything we need to expose
})

您可以将路由器添加为Pinia 插件
// src/main.js
import { createPinia } from 'pinia'
import { createApp, markRaw } from 'vue'
import { createRouter, createWebHistory } from 'vue-router'
import App from './App.vue'
import Home from './views/HomePage.vue'
import Api from './api.js' // my axios wrapper
const app = createApp(App)
// I usually put this in a separate file src/router.js and export the router
const routes = [
{ path: '/', component: HomePage },
]
const router = createRouter({
history: createWebHistory(),
routes,
})
const pinia = createPinia()
pinia.use(({ store }) => {
store.router = markRaw(router)
store.api = markRaw(Api)
})
app
.use(pinia)
.use(router)
.mount('#app')

然后router和api可用于this
// src/stores/user.js
import { defineStore } from 'pinia'
export const useUserStore = defineStore('User', {
state: () => ({}),
actions: {
async login() {
await this.api.POST('login', {username, password})
this.router.replace({name: 'home'})
}
}
})

请注意,您不能this.router使用箭头函数进行调用。
login: async () => {
this.router.replace({name: 'home'}) // error
}

this.router和的类型this.api:// src/global.d.ts
import { Router } from 'vue-router'
import Api from './api'
export { }
declare global {
}
declare module 'pinia' {
export interface PiniaCustomProperties {
router: Router,
api: typeof Api
}
}

我在 pinia github 上找到了这种方法。 https://github.com/vuejs/pinia/discussions/1092
但我还是不知道如何添加this.route到Pinia。
未来的读者,如果您知道该怎么做,请发表评论。
useRoute并且useRouter必须在 Vue 组件中使用,特别是setup方法或内部script setup。如果你想访问它router,你可以简单地导入它:
路由器文件
import { createRouter, createWebHistory } from 'vue-router'
export const router = createRouter({
history: createWebHistory(),
routes: [/* ... */]
})

然后在您的 pinia 商店中,您可以导入并使用该文件中的路由器:
import { defineStore } from 'pinia'
import router from './router'
export const myStore = defineStore('myStore', () => {
// router.push
// router.replace
})
