Question

我的大学项目之一是使用Android Studio创建移动应用程序，并且该应用程序必须使用REST API，Google登录和身份验证。我的应用程序将访问用户的私有Google图书库。为此，我创建了一个Google登录以验证用户身份。

        Scope SCOPE_BOOKS =
            new Scope("https://www.googleapis.com/auth/books");

    GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestIdToken(getString(R.string.default_web_client_id))
            .requestEmail()
            .requestProfile()
            .requestScopes(SCOPE_BOOKS)
            .build();

    mGoogleApiClient = new GoogleApiClient.Builder(MainActivity.this)
            .enableAutoManage(this, this )
            .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
            .addScope(SCOPE_BOOKS)
            .build();

一切正常。我什至会收到一个对话框，要求用户允许我的应用程序访问其Google图书。从现在开始我要去哪里？如何获得访问令牌？等

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

    AuthCredential credential = GoogleAuthProvider.getCredential(acct.getIdToken(), null);
    firebaseAuth.signInWithCredential(credential)
            .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                @Override
                public void onComplete(@NonNull Task<AuthResult> task) {
                    if (task.isSuccessful()) {
                        // Sign in success, update UI with the signed-in user's information
                        Log.d(TAG, "signInWithCredential:success");
                        FirebaseUser user = firebaseAuth.getCurrentUser();
                        mStatusTextView.setText(getString(R.string.signed_in_fmt, user.getDisplayName()));
                        Glide.with(MainActivity.this).load(user.getPhotoUrl()).into(mBannerImageView);
                        AddToLocalStorage("userData", "DisplayName", user.getDisplayName());
                        AddToLocalStorage("userData", "Email", user.getEmail());
                        AddToLocalStorage("userData", "Avatar", user.getPhotoUrl().toString());
                        AddToLocalStorage("userData", "UserId", user.getUid());

                        Toast.makeText(MainActivity.this,
                                "Welcome, " + user.getDisplayName(), Toast.LENGTH_SHORT).show();

                        updateUI(true);
                    } else {
                        // If sign in fails, display a message to the user.
                        Log.w(TAG, "signInWithCredential:failure", task.getException());
                        //Toast.make(findViewById(R.id.main_layout), "Authentication Failed.", Snackbar.LENGTH_SHORT).show();
                        updateUI(false);
                    }
                    hideProgressDialog();
                }
            });
}

如何创建回调以授予访问令牌？我已经从一开始就知道Google的oAuth是一件麻烦事，尤其是尝试访问用户的私人数据时。有人可以挥舞魔杖来帮助同学吗？
