用google用create-react-native-app和firebase登錄（使用指數）

Question

通過這段代碼。

googleAuthenticate = (token) => { 
const provider = firebase.auth.GoogleAuthProvider(); 
const credential = provider.credential(token) 
return firebase.auth().signInWithCredential(credential) } 


gglogin = async() => { 
const LogInResult = await Google.logInAsync({ 
     androidClientId: '<my-androidClientId>', 
     iosClientId: '<my-IOSClientId>', 
     scopes: ['profile', 'email'] 
}); 

if(LogInResult.type === 'success'){ 
    Alert.alert(
     'Logged in!', 
     `Hi ${user.name}!`, 
    ); 
    this.googleAuthenticate(LogInResult.accessToken) 
} 

}

這是可以得到的用戶名警報，但不能發送令牌通過得到這個錯誤火力地堡。

Possible Unhandled Promise Rejection (id: 0): 
    TypeError: this.addScope is not a function. (In 
'this.addScope("profile")', 'this.addScope' is undefined)` 

請什麼是錯的

Answer 1

我注意到2個問題，證書是一個靜態方法，並且第一個參數是一個ID令牌和第二訪問令牌（你逝去的訪問令牌似乎）：

const credential = firebase.auth.GoogleAuthProvider.credential(null, token); 
return firebase.auth().signInWithCredential(credential); 

Answer 2

你有你的範圍添加到下面提供商：

var provider = new firebase.auth.GoogleAuthProvider(); 
provider.addScope('profile'); 
provider.addScope('email'); 
firebase.auth().signInWithRedirect(provider); 

請再次檢查這個文件： https://firebase.google.com/docs/reference/js/firebase.auth.GoogleAuthProvider

您需要更改代碼如下：

googleAuthenticate = (token) => { 
const provider = firebase.auth.GoogleAuthProvider(); 
provider.addScope('profile'); 
provider.addScope('email'); 
const credential = provider.credential(token) 
return firebase.auth().signInWithCredential(credential) }
