Question

我已经使用此链接在 Firebase 上启用了 Google SignIn https://rnfirebase.io/auth/social-auth我的应用程序编译正常，但是当我按下登录按钮并选择 Google 帐户进行登录时，我得到了可能的未处理承诺拒绝（id：0）：错误：DEVELOPER_ERROR https://rnfirebase.io/auth/social-auth 我有 Windows 10 和

react-native-cli: 2.0.1
react-native: 0.63.4
Node : v12.16.0

这是App.js

    import React , {useState , useEffect} from 'react';
    import { Text TextInput, View } from 'react-native';
    import {ButtonTemplate} from '../assets/ButtonTemplate'
    import auth from '@react-native-firebase/auth';
    import { GoogleSignin } from '@react-native-community/google-signin';

    const App = () => {

    useEffect(()=> {
        GoogleSignin.configure({
            webClientId: 'xxxxxxxxxxxxxx.apps.googleusercontent.com',
        });
        })

    async function onGoogleButtonPress() {
            // Get the users ID token
            const { idToken } = await GoogleSignin.signIn();
        
            // Create a Google credential with the token
            const googleCredential = auth.GoogleAuthProvider.credential(idToken);
        
            // Sign-in the user with the credential
            return auth().signInWithCredential(googleCredential);
        }
    const googleLogin=()=>{
            console.log('Google SignIn');
            onGoogleButtonPress().then(() => console.log('Signed in with Google!'))
            }

    return (
    <ButtonTemplate 
                text={"Continue With Google"} 
                backgroundColor={'#5384ed'}
                fontSize={16}
                marginTop= {'3%'}
                iconText={'G'}
                justifyContent={'flex-start'}
                onPress={googleLogin}
                />
    )
    };

    export default App;

这是错误

Answer 1

我有两个问题，第一个问题是上面的，第二个An OAuth2 client already exists for this package name and SHA-1 in another project.问题是在 Firebase 中添加 SHA1 到项目中时的第二个问题。我解决了这个问题

1. 删除debug.keystore
2. 然后通过这个重新生成它keytool -genkey -v -keystore debug.keystore -alias androiddebugkey -storepass android -keypass android -keyalg RSA -validity 10000
3. keytool -keystore debug.keystore -list -v然后在给出位于的密码后通过此命令获取 SHA1 和 SHA256android/App/build.gradle then signingConfigs there is store password
4. 在 Firebase 我的项目中添加了 SHA1 和 SHA256
5. 下载最新的 JSON 文件并将最新的 JSON 添加到我的项目android/App文件夹中
6. 然后清理 gradlecd android && ./gradlew clean
7. 卸载应用程序然后执行npx react-native run-android
8. 现在它可以工作了:)
