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 时LoginButton，我会收到 Gmail 登录提示，我输入了我的凭据，但随后它返回到带有 的屏幕，LoginButton我遇到了错误：

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

我尝试过的：

• 添加google-services.json到 /android/app 并添加GoogleService-Info.plist到 ios/Runner。
• 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GoogleSignIn在我的一个已经处于生产级别的应用程序中实现..

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

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

但是，again..I解决it..by加2个SHA1键将FireBase Project..one的debug mode和其他的release mode..

如果我只放置调试SHA1密钥..它不能在release模式下工作但在模式下工作正常debug，如果我只放置releaseSHA1 密钥..它不在debug模式下工作但在模式下工作正常release。

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..

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

gradlew signingReport

它会给SHA1钥匙..

一个密钥由 生成，debug keystore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..不确定它是否也是生成密钥的相同过程Mac..
