得到错误：类型为"Google.GoogleSignIn+SignInException"的开发人员错误异常--- unity、firebase、google login？

Question

我正在unity中开发一个应用程序。我使用firebase谷歌登录方法。基本上谷歌登录是有效的，用户登录后被列在谷歌firebase用户日志中。问题是，它抛出了一个错误。因此无法从消防仓库获取数据。即使没有firestore代码，该应用程序也显示错误

获取错误：类型为的DeveloperError异常"Google.GoogleSignIn+SignInException"被抛出

可能有什么问题。

下面是我的代码

public class GoogleSignInDemo : MonoBehaviour
{
public Text infoText;
private string webClientId = "xxxxxxaaaaaaabbbb.apps.googleusercontent.com";

private FirebaseAuth auth;
private GoogleSignInConfiguration configuration;

private void Awake()
{
configuration = new GoogleSignInConfiguration { WebClientId = webClientId, RequestEmail = true, RequestIdToken = true };
CheckFirebaseDependencies();
}

private void CheckFirebaseDependencies()
{
FirebaseApp.CheckAndFixDependenciesAsync().ContinueWith(task =>
{
if (task.IsCompleted)
{
if (task.Result == DependencyStatus.Available)
auth = FirebaseAuth.DefaultInstance;
else
AddToInformation("Could not resolve all Firebase dependencies: " + task.Result.ToString());
}
else
{
AddToInformation("Dependency check was not completed. Error : " + task.Exception.Message);
}
});
}

public void SignInWithGoogle() { OnSignIn(); }
public void SignOutFromGoogle() { OnSignOut(); }

private void OnSignIn()
{
GoogleSignIn.Configuration = configuration;
GoogleSignIn.Configuration.UseGameSignIn = false;
GoogleSignIn.Configuration.RequestIdToken = true;

GoogleSignIn.DefaultInstance.SignIn().ContinueWith(OnAuthenticationFinished);
}

private void OnSignOut()
{
AddToInformation("Calling SignOut");
GoogleSignIn.DefaultInstance.SignOut();
}

public void OnDisconnect()
{
AddToInformation("Calling Disconnect");
GoogleSignIn.DefaultInstance.Disconnect();
}

internal void OnAuthenticationFinished(Task<GoogleSignInUser> task)
{
if (task.IsFaulted)
{
using (IEnumerator<Exception> enumerator = task.Exception.InnerExceptions.GetEnumerator())
{
if (enumerator.MoveNext())
{
GoogleSignIn.SignInException error = (GoogleSignIn.SignInException)enumerator.Current;
AddToInformation("Got Error: " + error.Status + " " + error.Message);
}
else
{
AddToInformation("Got Unexpected Exception?!?" + task.Exception);
}
}
}
else if (task.IsCanceled)
{
AddToInformation("Canceled");
}
else
{
AddToInformation("Welcome: " + task.Result.DisplayName + "!");
AddToInformation("Email = " + task.Result.Email);
AddToInformation("Google ID Token = " + task.Result.IdToken);
AddToInformation("Email = " + task.Result.Email);
SignInWithGoogleOnFirebase(task.Result.IdToken);

SceneManager.LoadScene(1); //Savad - Load Welcome screen when Google Login
}
}

private void SignInWithGoogleOnFirebase(string idToken)
{

AddToInformation("nError code = " + inner.ErrorCode + " Message = " + inner.Message);

}

{
GoogleSignIn.Configuration = configuration;
GoogleSignIn.Configuration.UseGameSignIn = true;
GoogleSignIn.Configuration.RequestIdToken = false;

AddToInformation("Calling Games SignIn");

GoogleSignIn.DefaultInstance.SignIn().ContinueWith(OnAuthenticationFinished);

以下是带有Firebase身份验证和GoogleSignIn库的Google SignIn代码的工作示例：

private void SignInWithGoogle(bool linkWithCurrentAnonUser)
{
GoogleSignIn.Configuration = new GoogleSignInConfiguration
{
RequestIdToken = true,
// Copy this value from the google-service.json file.
// oauth_client with type == 3
WebClientId = "[YOUR API CLIENT ID HERE].apps.googleusercontent.com"
};

Task<GoogleSignInUser> signIn = GoogleSignIn.DefaultInstance.SignIn();

TaskCompletionSource<FirebaseUser> signInCompleted = new TaskCompletionSource<FirebaseUser>();
signIn.ContinueWith(task =>
{
if (task.IsCanceled)
{
signInCompleted.SetCanceled();
}
else if (task.IsFaulted)
{
signInCompleted.SetException(task.Exception);
}
else
{
Credential credential = Firebase.Auth.GoogleAuthProvider.GetCredential(((Task<GoogleSignInUser>)task).Result.IdToken, null);
if (linkWithCurrentAnonUser)
{
mAuth.CurrentUser.LinkWithCredentialAsync(credential).ContinueWith(HandleLoginResult);
}
else
{
SignInWithCredential(credential);
}
}
});
}

该参数用于登录，目的是将新的谷歌帐户与当前登录的匿名用户链接。如果需要，可以忽略该方法的这些部分。请注意，所有这些都是在正确初始化Firebase Auth库之后调用的。

自述文件页面包含为您的环境获取此设置的分步说明。在遵循这些并使用上面的代码之后，你应该可以在android和iOS上使用它。

以下是上面代码中使用的SignInWithCredential方法：

private void SignInWithCredential(Credential credential)
{
if (mAuth != null)
{
mAuth.SignInWithCredentialAsync(credential).ContinueWith(HandleLoginResult);
}
}
`mAuth` is a reference to FirebaseAuth:
mAuth = Firebase.Auth.FirebaseAuth.DefaultInstance;

Answer 2

对于从@DIGI Byte请求HandleLoginResult的人，以下是代码，出于调试目的，可以随意删除try/catch块：

private void HandleLoginResult(Task<FirebaseUser> task)
{
try
{
if (task.IsCanceled)
{
UnityEngine.Debug.LogError("SignInWithCredentialAsync was canceled.");
return;
}
if (task.IsFaulted)
{
UnityEngine.Debug.LogError("SignInWithCredentialAsync encountered an error: " + task.Exception.InnerException.Message);
return;
}
else
{
FirebaseUser newUser = task.Result;
UnityEngine.Debug.Log($"User signed in successfully: {newUser.DisplayName} ({newUser.UserId})");
}
}
catch (Exception e)
{
if (e != null)
{
UnityEngine.Debug.Log(e.InnerException.Message);
}
}
}

您有类似got error developer error exception of type 'google.googlesignin+signin exception' was thrown的错误？

APK和AAB文件具有不同的SHA1和SHA256。在Firebase中，最好为这两个应用程序添加SHA。

您可以在Google Play控制台->中从AAB文件检查SHA您的应用程序->配置->应用程序完整性->应用程序签名。我将这些SHA密钥添加到Firebase，问题就消失了。
