【中文标题】React Native - FirebaseError: Firebase: No Firebase App \'[DEFAULT]\' has been created【英文标题】:React Native - FirebaseError: Firebase: No Firebase App '[DEFAULT]' has been createdReact Native - FirebaseError: Firebase: No Firebase App '[DEFAULT]' has been created 【发布时间】:2021-12-16 19:26:56 【问题描述】:发生此问题时,我正在尝试进行电子邮件身份验证
FirebaseError:Firebase:没有创建 Firebase 应用“[DEFAULT]” - 调用 Firebase App.initializeApp() (app/no-app)。
从我读到的东西,人们说这个问题是关于时间问题,但我不确定我的应用程序中这个错误的原因是什么
import React from 'react';
import ScrollView, StyleSheet, Text, View from 'react-native';
import Button, Gap, Input from '../../components/atoms';
import Fire from '../../config';
import Header from '../../components/molecules';
import useForm from '../../utils';
import getAuth, createUserWithEmailAndPassword from 'firebase/auth';
export default function Register()
const [form, setForm] = useForm(
fullName: '',
bloodType: '',
email: '',
password: '',
);
const onContinue = () =>
console.log(form);
const auth = getAuth();
createUserWithEmailAndPassword(auth, form.email, form.password)
.then(success =>
// Signed in
console.log('register success: ', success);
// ...
)
.catch(error =>
const errorMessage = error.message;
console.log('error register: ', errorMessage);
// ..
);
;
return (
<View>
<Header title="Register User" />
<View style=styles.content>
<ScrollView showsVerticalScrollIndicator=false>
<Input
label="Full Name"
value=form.fullName
onChangeText=value => setForm('fullName', value)
/>
<Gap height=24 />
<Input
label="Golongan Darah"
value=form.bloodType
onChangeText=value => setForm('bloodType', value)
/>
<Gap height=24 />
<Input
label="Email"
value=form.email
onChangeText=value => setForm('email', value)
/>
<Gap height=24 />
<Input
label="Password"
value=form.password
onChangeText=value => setForm('password', value)
secureTextEntry
/>
<Gap height=40 />
<Button title="Register" onPress=onContinue />
</ScrollView>
</View>
</View>
);
我将我的配置(Fire)放在 getAuth 导入之前,所以我现在有什么遗漏吗?
【问题讨论】:
你能分享一下配置文件(从哪里导入 Fire)吗?我建议在同一个文件中初始化身份验证并从那里导出。 我把配置ss放在底部@Dharmaraj 【参考方案1】:我建议在配置中初始化和导出所需的 Firebase 服务,如下所示:
import initializeApp from 'firebase/app'
import getAuth from 'firebase/auth'
const Fire = initializeApp(...firebaseConfig)
const auth = getAuth(Fire);
export auth
您现在可以导入此auth
实例并将其与createUserWithEmailAndPassword
一起使用,而不是在每个组件中使用getAuth()
。
