Question

我有一个Flutter应用程序，并且我试图允许用户登录其Gmail，因为我希望能够列出其电子邮件。当我按下LoginButton时，系统会提示您输入Gmail密码，然后输入凭据，但随后又返回LoginButton到屏幕，并且出现错误：

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

我尝试过的事情：

将google-services.json添加到/ android / app，并将GoogleService-Info.plist添加到ios / Runner。
启用gmail以进行Firebase身份验证。
将调试SHA1和SHA256添加到我的Firebase身份验证中。
填写OAuth同意书（我在其他所有步骤后都这样做了。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

我也遇到了这个问题。以我为例，我尝试在已经处于生产级别的其中一个应用中实现GoogleSignIn。

当我尝试执行此操作时..我也遇到了相同的错误.. APIException: 10 ..看起来您的情况也相同。.

我尝试了很多次。.但最终，我最终妥协了，并决定不在我的应用程序中包含GoogleSignIn。

但是，..我又通过在SHA1上添加2个FireBase Project键来解决了这个问题。.一个用于debug mode，另一个用于release mode .. < / p>

如果仅放置调试SHA1键，则它在release模式下不起作用，但在debug模式下工作良好，并且仅放置release SHA1键。 .it无法在debug模式下工作，但可以在release模式下工作。

不确定为什么会发生..但是它正在发生..并且以某种方式可以正常工作..

好吧..现在.. debug和release键是什么..它们不一样..我如何获得它们..？

是这里。

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

gradlew signingReport

它将提供SHA1键。.

debug keystore生成一个密钥，release keystore生成另一个密钥。

将它们都添加到项目中。并且它（希望如此）..就像对我一样。

希望有帮助。

注意：我使用的是Windows。不确定是否在Mac上生成密钥是否也是同一过程。

只需连接SHA并解决问题 https://developers.google.com/android/guides/client-auth

并替换以下分析依赖项：

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

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