Flutter：平台异常（sign_in_failed，com.google.android.gms.common.api.异常： 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，因为我想能够列出他们的电子邮件。当我按下我的LoginButton时，我会收到Gmail登录的提示，我输入了我的凭据，但随后它会返回到带有LoginButton的屏幕，我面临错误：

未处理的异常：平台异常（sign_in_failed，com.google.android.gms.common.api.异常：10：，空）

我尝试过：

• 向 /android/app添加了google-services.json，并向ios/Runner添加了GoogleService-Info.plist。
• 启用gmail进行Firebase身份验证。
• 将调试SHA1和SHA256添加到Firebase身份验证中。
• 填写OAuth同意书（在其他一切之后，我这样做了。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

只需连接SHA，问题就解决了https://developers.google.com/android/guides/client-auth

并替换分析依赖项：

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

Answer 2

我也面临着这个问题。。在我的例子中，我试图在我的一个已经处于生产水平的应用程序中实现GoogleSignIn。。

当我试着这么做的时候。。我也犯了同样的错误<代码>APIException:10。。看来你的案子也一样。。

我尝试了很多次...但是，最后，我妥协了，决定不包括GoogleSignIn在我的应用程序...

但是，再一次...我解决了它...通过向FireBase Project添加2个SHA1键...一个用于调试模式，另一个用于发布模式...

如果我只放debugSHA1键...它在释放模式下不工作，但在debug模式下工作正常，如果我只放释放SHA1键...它在debug中不工作模式，但在释放模式下工作正常。

不知道为什么会这样。。但它正在发生。。不知怎么的，它工作得很好。。

好的...现在...什么是debug和释放键...它们不一样吗...我怎么得到它们...？

在这里它是...

进入你的项目在命令提示符...然后cd android然后键入...

gradlew signingReport

它将给出SHA1键。。

有一个密钥由debug keystore生成，另一个由释放keystore生成。

将它们都添加到项目中。。而且它很有效（希望如此）。。就像对我一样。。

希望有帮助。。

注意：我正在使用Windows...不确定是否在Mac上生成密钥的过程是相同的...
