Luk*_*ter 5 javascript firebase react-native firebase-authentication expo
我有一个firebaseConfig.js看起来像这样的:
import { initializeApp } from "firebase/app";
import { initializeAuth } from "firebase/auth";
import { getReactNativePersistence } from "firebase/auth/react-native";
import { AsyncStorage } from "@react-native-async-storage/async-storage";
import { getFirestore } from "firebase/firestore";
const firebaseConfig = {...};
export const app = initializeApp(firebaseConfig);
const authState = initializeAuth(app, {
persistence: getReactNativePersistence(AsyncStorage)
});
export const auth = authState;
export const db = getFirestore(app);

然后,当我登录用户时,它看起来像这样:
import { auth } from "../../firebaseConfig";
...
signInWithEmailAndPassword(auth, email.trim(), password)
.then(() => {
// Handle success.
})

然后在 App.js 中,我有这个:
import { onAuthStateChanged } from "firebase/auth";
import { auth } from "./firebaseConfig";
...
onAuthStateChanged(auth, user => {
if (user) {
...
} else {
console.log("No user");
}
});

每次我刷新应用程序时,我都没有从onAuthStateChanged. 它在登录或注册后成功检测到用户,但在刷新应用程序后却无法检测到。
我究竟做错了什么?
