javascript - 如何在 Firebase Modular SDK V9 中使用 setPersistence？

Question

我尝试登录firebase 9版本持久性:

setPersistence(auth, firebaseApp.auth.Persistence.LOCAL).then( async() => {
  // login
}).catch((e) => {
  this.error = e.message
})

显示错误:

Uncaught TypeError: Cannot read property 'Persistence' of undefined

任何线索？

您需要以这种方式导入持久性状态:

import {
  getAuth,
  setPersistence,
  browserLocalPersistence,
  browserSessionPersistence,
  inMemoryPersistence
} from "firebase/auth";

const auth = getAuth()

await setPersistence(auth, browserLocalPersistence);

命名空间版本 V8
模块化版本 V9

firebase.auth.Auth.Persistence.LOCAL browserLocalPersistence firebase.auth.Auth.Persistence.SESSION browserSessionPersistence firebase.auth.Auth.Persistence.NONE inMemoryPersistence
