[英]Obtaining accessToken for google sign-in (Android)
I'm using Google sign-in in my application我在我的应用程序中使用 Google 登录
the problem is that I want to obtain accessToken
to send it to the back end server, but the GoogleSignInAccount
dosen't have it问题是我想获取
accessToken
以将其发送到后端服务器,但GoogleSignInAccount
没有它
private fun handleGoogleSignInResult(task: Task<GoogleSignInAccount>) {
task.addOnSuccessListener { googleSignInAccount ->
// TODO: Obtaining accessToken
}
task.addOnFailureListener { e ->
Timber.e(e)
showToast(R.string.something_went_wrong_try_again_later)
}
}
I suspect you might have to cast the AuthCredential
to OAuthCredential
to get the accessToken
.我怀疑您可能必须将
AuthCredential
为OAuthCredential
才能获取accessToken
。 Try the below.试试下面的。 Note, I did not run this code to verify.
注意,我没有运行这段代码来验证。 Some additional information here: Firebase Docs
这里有一些附加信息: Firebase 文档
private fun firebaseAuthWithGoogle(idToken: String) {
val credential = GoogleAuthProvider.getCredential(idToken, null)
val auth = Firebase.auth
auth.signInWithCredential(credential)
.addOnCompleteListener(this) { task ->
if (task.isSuccessful) {
// Sign in success, update UI with the signed-in user's information
val user = auth.currentUser
val oAuthCredential = credential as OAuthCredential
val token = oAuthCredential.accessToken
} else {
// If sign in fails, display a message to the user.
}
}
}
UPDATE The above fails as casting fails.更新以上失败,因为铸造失败。
Seems like the Android SDK does not provide an easy way to get the access code.似乎 Android SDK 没有提供获取访问代码的简单方法。
Have a look at this link for another option: GoogleAuthUtil Beware of some of the info mentioned in the link like running this async etc. You might be able to get the access token so:查看此链接以获取另一个选项: GoogleAuthUtil请注意链接中提到的一些信息,例如运行此异步等。您可能可以获得访问令牌,因此:
val scope = "oauth2:" + Scopes.EMAIL + " " + Scopes.PROFILE;
val account = GoogleSignIn.getLastSignedInAccount(this)
val token = GoogleAuthUtil.getToken(this, account?.account, scope)
