颤振: PlatformException(sign_in_failed，sign_in_failed 10：，null)

Question

我有一个颤栗的应用程序，我试图让用户登录他们的Gmail，因为我想能够列出他们的电子邮件。当我按下我的LoginButton时，它会提示我使用Gmail登录，然后输入我的凭据，但是它会返回到屏幕上，然后我将面临错误：

Unhandled Exception: PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 10: , null)

我试过的是：

ios/Runner.

• Enabling

• 将google-services.json添加到/android/app中，并将GoogleService-Info.plist添加到用于Firebase的gmail、authentication.

• Adding、my debug SHA1和SHA256到firebase authentication.

• Filling out OAuth consent表单中(我完成了其他所有操作之后)。我不知道这是否会影响它。)

。

有什么想法吗？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

我也面临着这个issue..In的问题，我试着在我的一个已经处于生产水平的应用程序中实现GoogleSignIn。

当我试图这么做的时候.我也犯了同样的错误..APIException: 10..看来你的案子也是一样的。

我尝试了许多times..but，最后，我最终妥协，并决定不包括GoogleSignIn在我的应用程序。

但是，我再次解决了it..by问题，在FireBase Project..one中为debug mode添加了2个SHA1密钥，为release mode添加了其他密钥。

如果只进行调试，SHA1 key..it不是在release模式下工作，而是在debug模式下工作，如果只在debug模式下工作，那么release SHA1 key..it不是在debug模式下工作，而是在release模式下工作。

不知道为什么是happening..but，它是happening..and，不知怎么的，它工作得很好。

Ok..now..what是debug和release键。他们不是same..how，我能得到他们吗..？

在这里..。

去Command Prompt的项目..。然后cd android，然后键入..。

gradlew signingReport

它会给SHA1密钥..。

有一个键由debug keystore生成，另一个键由release keystore生成。

将它们添加到project..and中--它(希望是)它为我做的..as。

希望能帮上忙..。

注意:我使用的是Windows..not，确定它是否也是在Mac上生成密钥的相同过程。

只需连接SHA和问题解决的https://developers.google.com/android/guides/client-auth

并将分析依赖项替换为：

implementation 'com.google.firebase:firebase-core:16.0.6'
