firebase - Flutter: PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 10: , null)

Question

我有一个 Flutter 应用程序，我试图允许用户登录他们的 Gmail，因为我希望能够列出他们的电子邮件。当我按下我的 LoginButton ，我收到 Gmail 登录提示，我输入了我的凭据，但随后它返回到带有 LoginButton 的屏幕。我面临错误:
Unhandled Exception: PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 10: , null)
我尝试过的:

已添加 google-services.json到/android/app 并添加 GoogleService-Info.plist到 ios/运行者。

为 Firebase 身份验证启用 Gmail。

将我的调试 SHA1 和 SHA256 添加到我的 firebase 身份验证中。

填写 OAuth 同意书(我在其他所有事情之后都这样做了。我不知道这是否会影响它。)

有任何想法吗？谢谢!

这是我的代码:

class AuthService {
  final GoogleSignIn _googleSignIn = GoogleSignIn();
  final FirebaseAuth _auth = FirebaseAuth.instance;
  final Firestore _db = Firestore.instance;

  Observable<FirebaseUser> user;
  Observable<Map<String, dynamic>> profile;
  PublishSubject loading = PublishSubject();

  AuthService() {
    user = Observable(_auth.onAuthStateChanged);

    profile = user.switchMap((FirebaseUser u) {
      if (u != null) {
        return _db
            .collection('users')
            .document(u.uid)
            .snapshots()
            .map((snap) => snap.data);
      } else {
        return Observable.just({});
      }
    });
  }

  Future<FirebaseUser> googleSignIn() async {
    loading.add(true);
    GoogleSignInAccount googleUser = await _googleSignIn.signIn();
    GoogleSignInAuthentication googleAuth = await googleUser.authentication;
    final AuthCredential credential = GoogleAuthProvider.getCredential(
      accessToken: googleAuth.accessToken,
      idToken: googleAuth.idToken,
    );
    FirebaseUser user = (await _auth.signInWithCredential(credential)).user;

    updateUserData(user);
    print("signed in " + user.displayName);

    loading.add(false);
    return user;
  }

  void updateUserData(FirebaseUser user) async {
    DocumentReference ref = _db.collection('user').document('user.uid');

    return ref.setData({
      'uid': user.uid,
      'email': user.email,
      'photoURL': user.photoUrl,
      'displayName': user.displayName,
      'lastSeen': DateTime.now()
    }, merge: true);
  }

  void signOut() {
    _auth.signOut();
  }
}

final AuthService authService = AuthService();

Answer 1

我也遇到了这个问题..就我而言，我尝试实现 GoogleSignIn在我已经处于生产级别的应用程序之一中..

当我尝试这样做时..我也遇到了同样的错误.. APIException: 10 .. 看起来你的也是一样的情况..

我尝试了很多次..但是，最后，我最终妥协并决定不包括 GoogleSignIn在我的应用程序中..

但是，再次..我解决了它..通过添加 2 SHA1 FireBase Project 的 key ..一个 debug mode和其他 release mode ..

如果我只放调试 SHA1关键..它在 release 中不起作用模式但在 debug 中工作正常模式，如果我只放 release SHA1 key ..它在 debug 中不起作用模式但在 release 中工作正常模式 。

不知道为什么会发生......但它正在发生......不知何故它工作正常......

好的...现在...什么是 debug和 release关键..它们不一样..我怎么得到它们..？

这里是..

转到您的项目 Command Prompt .. 然后 cd android然后输入..

gradlew signingReport

它会给 SHA1 key ..
debug keystore生成了一个 key 另一个由 release keystore ..

将它们都添加到项目中......它可以工作(希望如此)......就像它对我一样......

希望能帮助到你..

注意:我正在使用 Windows ..不确定在 Mac 上生成 key 是否是相同的过程还有..
