你好!要获取错误的详细信息,你可以使用类型断言来检查错误类型,并从中获取代码。在你的代码中,你可以这样处理错误:

fbUser, err := s.auth.CreateUser(ctx, fbUserParams)
if err != nil {
    if firebaseErr, ok := err.(*firebaseAuth.Error); ok {
        // 获取错误代码
        errorCode := firebaseErr.Code
        // 处理特定错误
        if errorCode == "email-already-exists" {
            // 处理已存在的电子邮件错误
        } else {
            // 处理其他错误
        }
    } else {
        // 处理非 firebaseAuth.Error 类型的错误
    }
}

通过将错误断言为 *firebaseAuth.Error 类型,你可以访问 Code 属性来获取错误代码。然后,你可以根据错误代码执行相应的处理逻辑。请确保导入正确的包并使用正确的类型。

希望这可以帮助到你!如果你有任何其他问题,请随时问。

New to Go and trying to understand how to access the error details. I've already created a user, and now I'm expecting to get a "email-already-exists" error:

    fbUser, err := s.auth.CreateUser(ctx, fbUserParams)
	if err != nil {
		return nil, errors.New("[email] already exists") // <- it could be any other error, and I want to be able to handle it
	}

Here's what I see in my debugger:

我认为你最好的选择是使用Errors.As函数。你可以在这里了解更多信息:https://pkg.go.dev/errors#As
Google Firebase返回的错误类型是FirebaseError,它包含两个属性:CodeString。你可以尝试使用以下代码片段:

fbUser, err := s.auth.CreateUser(ctx, fbUserParams)
if err != nil {
    var firebaseErr *FirebaseError
    if errors.As(err, &firebaseErr) {
        // 在这里你可以访问"Code"和"String"
    } else {
        return nil, errors.New("[email] already exists")
    }
}

通过这段代码,你应该能够处理你需要的内容。请注意正确导入提供FirebaseError类型的包。也许先阅读一些Firebase文档会有所帮助。
希望这可以帮到你!

I think that the best option you have is using the Errors.As function. You can learn more about it at here: https://pkg.go.dev/errors#As
The error returned by Google Firebase is of type FirebaseError that involves two properties: Code and String. You can try with the following code snippet:

fbUser, err := s.auth.CreateUser(ctx, fbUserParams)
if err != nil {
    var firebaseErr *FirebaseError
    if errors.As(err, &firebaseErr) {
        // here you can access "Code" and "String"
    } else {
        return nil, errors.New("[email] already exists")
    }
}

Thanks to this code you should be able to manage what you need. Pay attention to import correctly the package that provides the type FirebaseError. Maybe read something on the Firebase documentation first.
Hope this helps!
