问题描述

        Auth.auth().signIn(withEmail: emailTextField.text!, password: passwordTextField.text!)
    { (user, error) in

        if error != nil {
            print(error!)
            self.warningLabel.isHidden = false;
            self.passwordTextField.text = "";
        } else {
            print("Log in succesful")
            self.performSegue(withIdentifier: "welcomeSeg", sender: self)
        }
    }

每当我登录或注册用户时,我只会打印通用警告标签,而不是实际问题.我打印了我收到的错误,它太冗长而无法显示给用户.

Whenever I sign in or sign up a user I just print a generic warning label instead of the actual issue. I print the error I receive and it's too verbose to show to the user.

错误域= FIRAuthErrorDomain代码= 17008电子邮件地址格式错误." UserInfo = {NSLocalizedDescription =电子邮件地址格式错误.,error_name = ERROR_INVALID_EMAIL}

Error Domain=FIRAuthErrorDomain Code=17008 "The email address is badly formatted." UserInfo={NSLocalizedDescription=The email address is badly formatted., error_name=ERROR_INVALID_EMAIL}

有什么方法可以获取错误代码,以便我可以更详细地了解错误消息吗?我仔细阅读了文档,但未提出任何建议.

Is there any way to fetch the error code so I can be more specific with my error messages? I've looked through the documentation but have been unsuccessful in coming up with anything.

推荐答案

我建议根据收到的错误创建一个AuthErrorCode对象(由Firebase SDK提供),并根据需要使用它.如果我没记错的话,AuthErrorCode是一个枚举,其中包含.wrongPassword.invalidEmail等情况.

I would recommend creating an AuthErrorCode object (provided by the Firebase SDK) from the error you receive and using that as you see fit. If I remember correctly, AuthErrorCode is an enum with cases like .wrongPassword, .invalidEmail, etc.

一个简单的伪代码示例:

A simple pseudocode example:

if error != nil {
    if let error = AuthErrorCode(rawValue: error?.code) {
        switch error {
        case .wrongPassword:
            // do some stuff with the error code
        }
}

我也感到你的痛苦.我发现在进行更改时,Swift SDK文档会滞后很多.

Also, I feel your pain. I've found that the Swift SDK documentation lags quite a bit when changes come along.
