Question

我刚刚使用Firebase 3.2.0启动了一个新项目（Swift 2.2; iOS 9; Xcode 7.3.1），并在输入无效的电子邮件时发出了以下错误，作为我的授权/注册过程的一部分一个弱密码：

NSError

Error Domain=FIRAuthErrorDomain Code=17999 "An internal error has occurred, print and 
inspect the error details for more information." UserInfo={error_name=ERROR_INTERNAL_ERROR, 
NSUnderlyingError=0x7c0549a0 {Error Domain=FIRAuthInternalErrorDomain Code=3 "(null)"

entries =>

}

)}

<CFString 0x7c0543a0 [0x1a701f8]>{contents = "INVALID_EMAIL"}
}
}}, NSLocalizedDescription=An internal error has occurred, print and inspect the error 
details for more information.}

...我的代码如下......

AuthViewController.swift

if let email = emailField.text where email != "", let password = passwordField.text where 
  password != "" {FIRAuth.auth()?.signInWithEmail(email, password: password) { (user, error) in
    if let error = error {
            if let errorCode = FIRAuthErrorCode(rawValue: error.code) {
                switch errorCode {
                case .ErrorCodeNetworkError:
                    print("A network error occurred")
                case .ErrorCodeUserNotFound:
                    print("ATTEMPTING TO CREATE USER")
                    FIRAuth.auth()?.createUserWithEmail(email, password: password) { (user, error) in
                        if let error = error {
                            if let errCode = FIRAuthErrorCode(rawValue: error.code) {
                                switch errCode {
                                case .ErrorCodeInvalidEmail:
                                    print("invalid email")
                                case .ErrorCodeWeakPassword:
                                    self.insertErrorLabel("Password is considered weak (< 6 characters). Try again")
                                default:
                                    print("Create User Error: \(error)")
                                }
                            }
                        } else {
                            // create a user in the database...
                        }
                    }
                case .ErrorCodeUserTokenExpired:

                ....

执行命中signInWithEmail（）中的.ErrorCodeUserNotFound案例。然后它在createUserWithEmail（）中遇到默认情况。

从文档看来，似乎在createUserWithEmail（）函数中有一个INVALID_EMAIL错误键可用，但是，它似乎抛出了一个内部错误，而不是遇到InvalidEmail错误情况。

三个问题：

我是否有一个可接受的流程，其中signIn失败导致createUser？
错误的实际原因是什么？
我该如何解决？

提前致谢。

Answer 1

为了供将来参考，我针对上述错误提出了一个错误，Firebase / Google已确认将在下一版SDK中解决此问题。

Answer 2

我遇到了同样的问题，发现我甚至无法通过Firebase控制台添加用户。但奇怪的是，我启用了禁用谷歌登录，我能够手动添加用户。所以我尝试创建一个createUserWithEmail的用户，但它确实有效。

您可能想尝试启用和禁用使用电子邮件功能登录，这可能会以某种方式重置Firebase端的某些设置以解决问题。这种“解决方法”让我相信问题出在他们的服务器端，而不是SDK。
