javascript - 尝试在 React Native 中使用 GoogleSignIn,然后可能出现未处理的 Promise Rejection(id:错误:DEVELOPER_ERROR
问题描述
我已经使用此链接https://rnfirebase.io/auth/social-auth在 Firebase 上启用了 Google登录 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,我得到了可能未处理的承诺拒绝(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

解决方案
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
- 然后通过这个重新生成它
keytool -genkey -v -keystore debug.keystore -alias androiddebugkey -storepass android -keypass android -keyalg RSA -validity 10000
- 然后
keytool -keystore debug.keystore -list -v
在给出位于android/App/build.gradle then signingConfigs there is store password
- 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
android/App
文件夹中添加最新的 JSON - 然后清理gradle
cd android && ./gradlew clean
- 卸载应用程序然后执行
npx react-native run-android
- 现在它的工作:)
