将认证数据保存到firebase React native

Question

我有一个react native应用程序它有一个注册与谷歌按钮当我点击登录我在控制台。日志中获取数据我想保存数据在firebase我想知道如何做到这一点

const googleLogin = async () => {
try {
await GoogleSignin.hasPlayServices();
const userInfo = await GoogleSignin.signIn();
console.log(userInfo);// i am getting user data here

} catch (error) {
if (error.code === statusCodes.SIGN_IN_CANCELLED) {
// user cancelled the login flow
} else if (error.code === statusCodes.IN_PROGRESS) {
// operation (e.g. sign in) is in progress already
} else if (error.code === statusCodes.PLAY_SERVICES_NOT_AVAILABLE) {
// play services not available or outdated
} else {
// some other error happened
}
}
};

你可以参考这个链接来获取google social authentication，这就是你要寻找的将认证数据保存到firebase的内容:

import auth from '@react-native-firebase/auth';
import { GoogleSignin } from '@react-native-google-signin/google-signin';
async function onGoogleButtonPress() {
// Check if your device supports Google Play
await GoogleSignin.hasPlayServices({ showPlayServicesUpdateDialog: true });
// 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);
}

这很有帮助。请确保您已经集成了用于firebase身份验证的所有库。

import {
GoogleSignin,
statusCodes,
} from '@react-native-google-signin/google-signin';
import auth, {FirebaseAuthTypes} from '@react-native-firebase/auth';
// This function will be call on tapping sign in with google button
const signInWithGoogle = async () => {
try {
// This will check whether there is Google play service or not
await GoogleSignin.hasPlayServices();
//This will give you userInformation
const userInfo = await GoogleSignin.signIn();
// This will create new credential which can help to signIn in firebase
const credential = auth.GoogleAuthProvider.credential(userInfo.idToken);

//Here we are trying to return promise so when we call function we can have promise object

return new Promise((resolve, reject) => {
auth()
.signInWithCredential(credential)
.then(response => {
console.log('response in', response);
resolve(response);
})
.catch(error => {
console.log('error in', error);
reject(error);
});
});
} catch (error) {
if (error.code === statusCodes.SIGN_IN_CANCELLED) {
// user cancelled the login flow
} else if (error.code === statusCodes.IN_PROGRESS) {
// operation (e.g. sign in) is in progress already
alert(JSON.stringify(error));
} else if (error.code === statusCodes.PLAY_SERVICES_NOT_AVAILABLE) {
// play services not available or outdated
alert(JSON.stringify(error));
} else {
alert(error);
}
}
};

现在当你在google button on press上调用这个函数时，它会给你promise对象，你可以像下面这样做。

onPress={() => {
SignInMethods.signInWithGoogle()
.then(response => {
console.log('user information from firebase authentication', response.user);
})
.catch(error => {
console.log('error in google sign in :', error);
});
}}
