javascript - 尝试在 React Native 中使用 GoogleSignIn，然后可能出现未处理的 Promise Rejection(id : Error: DEVELOPER_ERROR

Question

我已使用此链接在 Firebase 上启用 Google 登录 https://rnfirebase.io/auth/social-auth我的应用程序编译得很好，但是当我按下登录按钮并选择一个 Google 帐户进行登录时，我得到了可能的未处理 promise 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是上面，第二个是 An OAuth2 client already exists for this package name and SHA-1 in another project.第二个问题是在 Firebase 中，同时在项目中添加 SHA1。
我解决了这个问题

删除 debug.keystore

然后通过这个 keytool -genkey -v -keystore debug.keystore -alias androiddebugkey -storepass android -keypass android -keyalg RSA -validity 10000 重新生成它

然后通过这个命令得到 SHA1 和 SHA256 keytool -keystore debug.keystore -list -v在给出位于 android/App/build.gradle then signingConfigs there is store password 中的密码后

在 Firebase 我的项目中添加了 SHA1 和 SHA256

下载最新的 JSON 文件在我的项目中添加最新的 JSON android/App文件夹

然后通过 cd android && ./gradlew clean 清理 gradle

卸载应用程序然后执行npx react-native run-android

现在它的工作:)
