升级firebase后OAuth2问题

Question

我有一个工作的Android应用程序(也许更好地说HAD).

该应用程序正在使用一些第三方库,包括:Google地图,Firebase,firebaseui.在转换应用程序以使用新的firebase后,我偶然发现了两个主要问题:

1. firebaseui登录屏幕已更改,现在看起来像这样(从登录对话框变为活动):

这当然与旧的完全不同,并且出于与调试构建变体不同的一些奇怪的原因.

2. 我无法使用google登录,并在logcat中显示以下错误:

com.google.firebase.FirebaseException:发生了内部错误.[找不到服务器配置中的OAuth2客户端ID.]

同样,这个问题在调试变体中没有发生.

为了清楚起见,调试版本变体使用相同的代码库,但使用不同的firebase数据库.

Answer 1

对于以下错误:

com.google.firebase.FirebaseException:发生了内部错误.[找不到服务器配置中的OAuth2客户端ID.]

1. 您必须首先访问凭据类别(https://console.developers.google.com/apis/credentials)中的Google开发人员控制台,然后找到名为"Web客户端(自动创建)"的自动生成的OAuth 2.0客户端ID Google服务)",保留与此客户端ID相关的数据.

2. 在"Auth"类别中转到Firebase控制台,然后转到"连接模式"选项卡,打开Goog​​le身份验证设置,最后展开Web SDK设置.现在粘贴以前找到的OAuth客户端ID及其密钥并保存设置.

更改的设置是关于Web设置,但它似乎由Firebase android组件使用.

通过 New Firebase，他们改变了很多代码和做事的方式。

现在，当您设置 Firebase 项目时，它们会为您提供输入 AuthId 的选项，您可以下载 JSON 并将其粘贴到您的应用程序中。

设置 ClientId 后，您可以添加此代码以使您的 Google 登录重新恢复工作。

 Button signInButton;
 //Google Variables
 private static final int RC_SIGN_IN = 9001;
 private GoogleApiClient mGoogleApiClient;

 //Firebase Variables
private FirebaseAuth mAuth;
private FirebaseAuth.AuthStateListener mAuthStateListener;

//Inside OnCreate();
//Google SignIn Methods
    // [START config_signin]
    // Configure Google Sign In
    GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestIdToken(getString(R.string.default_web_client_id))
            .requestEmail()
            .build();
    // [END config_signin]

    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .enableAutoManage(this /* FragmentActivity */, this /* OnConnectionFailedListener */)
            .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
            .build();


    mAuth = FirebaseAuth.getInstance();

    mAuthStateListener = new FirebaseAuth.AuthStateListener() {
        @Override
        public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
            FirebaseUser user = firebaseAuth.getCurrentUser();
            updateUI(user);
        }
    };

 @Override
protected void onStart() {
    super.onStart();
    mAuth.addAuthStateListener(mAuthStateListener);
    mGoogleApiClient.connect();
}


@Override
protected void onStop() {
    super.onStop();
    if(mAuthStateListener != null) {
        mAuth.removeAuthStateListener(mAuthStateListener);
    }
    mGoogleApiClient.disconnect();
}

// [START onactivityresult]
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == RC_SIGN_IN) {
        GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
        if (result.isSuccess()) {
            // Google Sign In was successful, authenticate with Firebase
            GoogleSignInAccount account = result.getSignInAccount();
            firebaseAuthWithGoogle(account);
        } else {
            // Google Sign In failed, update UI appropriately
            // [START_EXCLUDE]
            updateUI(null);
            // [END_EXCLUDE]
        }
    }

}
// [END onactivityresult]


private void firebaseAuthWithGoogle(GoogleSignInAccount acct) {
    AuthCredential credential = GoogleAuthProvider.getCredential(acct.getIdToken(), null);
    mAuth.signInWithCredential(credential)
            .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                @Override
                public void onComplete(@NonNull Task<AuthResult> task) {

                    // If sign in fails, display a message to the user. If sign in succeeds
                    // the auth state listener will be notified and logic to handle the
                    // signed in user can be handled in the listener.

                    if (!task.isSuccessful()) {
                        Toast.makeText(LoginActivity.this, "Authentication failed.",
                                Toast.LENGTH_SHORT).show();
                    }
                }
            });
}
// [END auth_with_google]

// [START signin]
private void signIn() {
    Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
    startActivityForResult(signInIntent, RC_SIGN_IN);
}
// [END signin]

   private void updateUI(FirebaseUser user) {
    if (user != null) {
      //write what you want to do after login here  
    }
}


@Override
public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {
    // An unresolvable error has occurred and Google APIs (including Sign-In) will not
    // be available.
    Toast.makeText(this, "Google Play Services error.", Toast.LENGTH_SHORT).show();
}

 public void GoogleSignIn(View v){
    signIn();
}


@Override
protected void onRestart() {
    super.onRestart();
    mGoogleApiClient.connect();
}

这对于在我的应用程序中使用 Firebase 进行 Google 身份验证完全正常
