Firebase身份验证的最新更改。 Google登录？ [英] Recent changes with Firebase Authentication via. Google Sign-In?

问题描述

我向使用Firebase Google登录身份验证的用户提出了一个问题：

I've a question to people who use Firebase Google Sign-In authentication:

我的应用已经使用了几个月，正在使用用于Firebase身份验证的Google登录和电子邮件/密码选项。然而大约一周前，我注意到Google登录已停止工作。没有代码被更改，电子邮件/密码选项也像往常一样工作。

My app, which has already been working for a couple of months, is using both Google Sign-In and e-mail/password options for Firebase Authentication. However about a week ago I've noticed that the Google Sign-In stopped working. No code was changed, also the e-mail/password option works just as usual.

我检查了文档（ https://firebase.google.com/docs/auth/android/google-signin ），它仍然是相同（我的应用程序从文档中复制身份验证方法）。

I've checked the documentation (https://firebase.google.com/docs/auth/android/google-signin), it's still the same (My app copies the authentication method from the documentation).

您是否也面临过类似的问题？如果是，请告诉我如何解决。

Did you face a similar problem too? If yes, please tell me how can I solve it.

以下是我在LoginActivity中与Google登录相关的代码：

Here is my code related to Google Sign-in inside my LoginActivity:

@Override
protected void onCreate(Bundle savedInstanceState) {
    ...
    ...   
    //--------Google Sign In
    GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestIdToken(getString(R.string.default_web_client_id))
            .requestEmail()
            .build();

    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .enableAutoManage(this, new GoogleApiClient.OnConnectionFailedListener() {
                @Override
                public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {
                    Toast.makeText(LoginActivity.this, "Connection failed!", Toast.LENGTH_SHORT).show();
                }
            })
            .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
            .build();

    mGoogleBttn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            SignIn();
        }
    });

}

private void SignIn() {
    Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
    startActivityForResult(signInIntent, RC_SIGN_IN);
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    mProgress.setMessage("Signing in with Google Account...");
    mProgress.show();
    // Result returned from launching the Intent from GoogleSignInApi.getSignInIntent(...);
    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
            // ...
            mProgress.dismiss();
            Toast.makeText(LoginActivity.this, "Google sign in failed!", Toast.LENGTH_SHORT).show();
        }
    }
}

private void firebaseAuthWithGoogle(GoogleSignInAccount acct) {
    Log.d(TAG, "firebaseAuthWithGoogle:" + acct.getId());

    AuthCredential credential = GoogleAuthProvider.getCredential(acct.getIdToken(), null);
    mAuth.signInWithCredential(credential)
            .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                @Override
                public void onComplete(@NonNull Task<AuthResult> task) {
                    Log.d(TAG, "signInWithCredential:onComplete:" + task.isSuccessful());

                    mProgress.dismiss();
                    checkUserExist();

                    // 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()) {
                        Log.w(TAG, "signInWithCredential", task.getException());
                        Toast.makeText(LoginActivity.this, "Authentication failed.",
                                Toast.LENGTH_SHORT).show();
                    }
                }
            });
}

private void checkUserExist() {
    final String user_id = mAuth.getCurrentUser().getUid();
    mDatabaseUsers.addValueEventListener(new ValueEventListener() {
        @Override
        public void onDataChange(DataSnapshot dataSnapshot) {
            if (dataSnapshot.hasChild(user_id)) {
                Intent mainIntent = new Intent(LoginActivity.this, MainActivity.class);
                mainIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                startActivity(mainIntent);
            } else {
                Intent setupIntent = new Intent(LoginActivity.this, SetupActivity.class);
                setupIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                startActivity(setupIntent);
            }
        }
        @Override
        public void onCancelled(DatabaseError databaseError) {
        }
    });
}

推荐答案

好的，我承认一件事 - 它与代码无关......我设法解决了这个问题，我将解释如何。

Okay, I'll admit one thing - it had nothing to do with the code... I managed to fix the issue, and I'll explain how.

我使用调试器调试了应用程序，因为我在评论中被好人推荐，结果发现在onActivityResult（）方法中，Auth.GoogleSignInApi.getSignInResultFromIntent（data）返回此错误结果代码：

I debugged the app with the debugger as I was recommended by good people inside the comments and it turned out that inside the onActivityResult() method the Auth.GoogleSignInApi.getSignInResultFromIntent(data) was returning this error result code:

状态{statusCode = DEVELOPER_ERROR，resolution = null}

Status{statusCode=DEVELOPER_ERROR, resolution=null}

这足以让我们了解在哪里挖掘。我查看了我的Firebase控制台 - >项目 - >项目设置 - > SHA-1指纹。

This was more than enough to understand where to dig. I looked up into my Firebase console -> Project -> Project settings -> SHA-1 fingerprints.

有趣的是 - 那里有指纹，我是指纹放在前面。无论如何，我决定检查它是否与我从Android Studio获得的相同 - > Gradle Projects - >在project / app / tasks / android /文件夹中有一个包含SHA-1的signingReport。令我惊讶的是，SHA-1指纹不匹配。无论如何，我从AS复制了它并在Firebase Console中添加了第二行。你猜怎么着？它现在有效...

What is interesting - there was a fingerprint there, the one I've put before. Anyways, I decided to check if it's the same with the one I get from Android Studio -> Gradle Projects -> inside the project/app/tasks/android/ folder there is a signingReport which contains SHA-1. To my surprise, the SHA-1 fingerprints did not match. Anyways, I copied it from the AS and added 2nd line inside Firebase Console. Guess what? It works now...

我仍然有很多关于为什么会发生这种情况的问题，因为它确实突然发生，正如我之前在我的问题中所解释的那样。

I still have a lot of questions about why this could happened, since it did happen all of a sudden as I explained previously in my question.

我希望这些信息可以帮助其他有类似问题的人。然而，问题已经解决了，但是因为有一个赏金集我将奖励给那个人，他会向我解释这个魔法......

I hope this info will help others who had a similar issue. Nevertheless, question solved, but since there is a bounty set I'll award it to the person, who'll explain me this magic...
