我正在使用 Okta 设置一个基本的 Vue 身份验证应用程序,基于以下内容:https://github.com/okta/okta-vue。我正在尝试将处理路由和登录重定向的逻辑从选项 API 转换为组合 API。换句话说,App.vue 中的登录/注销功能,目前是这样写的:
async login () {
await this.$auth.signInWithRedirect()
this.$router.push('/protected')
},
async logout () {
await this.$auth.signOut()
}
https://github.com/okta/okta-vue#show-login-and-logout-buttons
在 Composition API 中可能看起来像这样(我认为):
setup() {
const router = useRouter()
const login = () => {
this.$auth.signInWithRedirect()
}
const logout = () => {
this.$auth.signOut()
}
return {login, logout, router}
}
但是,我不确定如何更改
this.$auth.signInWithRedirect()
和 this.$auth.signOut()
以使用 Composition API,因为 $auth 似乎不是可接受的属性。如何设置 Okta 方法 signInWithRedirect()
和 signOut()
来使用组合 API?我对 Typescript 中的 Composition API 和 Vue 很陌生。感谢反馈!
下面是其余代码:
应用程序.vue
<template>
<div id="app">
<button v-if='authState && authState.isAuthenticated' @click='logout' id='logout-button'> Logout </button>
<button v-else @click='login' id='login-button'> Login </button>
<router-view/>
</div>
</template>
<script lang="ts">
import { defineComponent } from 'vue'
import { useRouter } from 'vue-router'
export default defineComponent({
name: 'app',
setup() {
const router = useRouter()
const login = () => {
this.$auth.signInWithRedirect()
router.push('/protected')
}
const logout = () => {
this.$auth.signOut()
}
return {login, logout, router}
}
})
</script>
main.ts
import { createApp } from 'vue'
import App from './App.vue'
import router from './router'
import { OktaAuth } from '@okta/okta-auth-js'
import OktaVue from '@okta/okta-vue'
const oktaAuth = new OktaAuth({
issuer: 'https://{dev-id}.okta.com/oauth2/default',
clientId: '{clientId}',
redirectUri: 'http://localhost:8080/login/callback',
scopes: ['openid', 'profile', 'email']
})
const app = createApp(App)
app.use(OktaVue, { oktaAuth })
app.use(router)
app.mount('#app')
路由器/index.ts
import { createRouter, createWebHistory, RouteRecordRaw } from 'vue-router'
import { LoginCallback } from '@okta/okta-vue'
import { navigationGuard } from '@okta/okta-vue'
import Protected from '../views/Protected.vue'
const routes: Array<RouteRecordRaw> = [
{
path: '/login/callback',
component: LoginCallback
},
{
path: '/protected',
name: 'Protected',
component: Protected,
meta: {
requiresAuth: true
}
}
]
const router = createRouter({
history: createWebHistory(process.env.BASE_URL),
routes
})
router.beforeEach(navigationGuard)
export default router
okta-vue
插件配置了一个名为$auth
的全局属性(它允许在选项API中使用
this.$auth
)。该属性的 值实际上与通过 oktaAuth
传递到插件 的 app.use(OktaVue, { oktaAuth })
实例相同(即,this.$auth
设置为 oktaAuth
)。
在 Composition API 中,您可以通过
getCurrentInstance()
访问应用程序的全局属性:
// MyComponent.vue
<script lang="ts">
import { getCurrentInstance } from 'vue'
import type { OktaAuth } from '@okta/okta-auth-js'
export default {
setup() {
const oktaAuth = getCurrentInstance()!!.appContext.app.config.globalProperties.$auth as OktaAuth
const login = () => oktaAuth.signInWithRedirect()
const logout = () => oktaAuth.signOut()
⋮
}
}
</script>
另一种方法是将
oktaAuth
实例移动到可以在需要时导入的共享文件中,因为 oktaAuth
与 $auth
全局属性相同:
// auth.ts
import { OktaAuth } from '@okta/okta-auth-js'
export const oktaAuth = new OktaAuth({
issuer: `https://${process.env.VUE_APP_OKTA_DOMAIN}/oauth2/default`,
clientId: `${process.env.VUE_APP_OKTA_CLIENT_ID}`,
redirectUri: window.location.origin + '/login/callback',
scopes: ['openid', 'profile', 'email'],
pkce: true,
})
// main.ts
import OktaVue from '@okta/okta-vue'
import { oktaAuth } from './auth' 👈
const app = createApp(App)
app.use(OktaVue, { oktaAuth })
⋮
// MyComponent.vue
<script lang="ts">
import { oktaAuth } from './auth' 👈
export default {
setup() {
const login = () => oktaAuth.signInWithRedirect()
const logout = () => oktaAuth.signOut()
⋮
}
}
</script>
最新版本的
okta-vue
导出可组合的 useAuth
,您可以在组件中使用它。 https://github.com/okta/okta-vue?tab=readme-ov-file#auth
import { useAuth } from '@okta/okta-vue';
const $auth = useAuth();
