Question

我将我的Firebase 2代码库转换为Firebase 3并遇到了一些麻烦。

所以基本上我试图找出如何在Firebase数据库的特定位置创建新用户。

目标 - 我想保存所有新用户@ var _USER_REF = FIRDatabaseReference().child("\(BASE_URL)/users")

到目前为止，这是代码。

class  DataService {

    static let dataService = DataService()

    let BASE_URL = "https://project-1321.firebaseio.com"
    var _BASE_REF = FIRDatabaseReference().child(BASE_URL)
    var _USER_REF = FIRDatabaseReference().child("\(BASE_URL)/users")
    var _NEWS_REF = FIRDatabaseReference().child("\(BASE_URL)/news")
    var _MARKET_STATS = FIRDatabaseReference().child("\(BASE_URL)/market")

    var CURRENT_USER_REF: FIRDatabaseReference {

        let userID = NSUserDefaults.standardUserDefaults().valueForKey("uid") as! String
        let currentUser = FIRDatabaseReference().child("\(_BASE_REF)").child("users").child(userID)
        //let currentUser = Firebase(url: "\(BASE_REF)").childByAppendingPath("users").childByAppendingPath(userID)
        return currentUser

    }



    func createNewAccount(uid: String, user: Dictionary<String, String>) {
        _USER_REF.child(uid).setValue(user)
    }



}

View Controller

@IBAction func registerAccount(sender: AnyObject) {

        guard let email = self.emailRegField.text where !self.emailRegField.text!.isEmpty else {
            return
        }

        guard let username = self.usernameRegField.text where !self.usernameRegField.text!.isEmpty else {
            return
        }

        guard let password = self.passwordRegField.text where !self.passwordRegField.text!.isEmpty else {
            return
        }

        FIRAuth.auth()?.createUserWithEmail(email, password: password) {
         (user, error) in

            if error != nil {
                print(error)
                self.signUpErrorAlert("Alert", message: "There was a problem signing up!")
            } else {

                let user = ["provider": user?.providerID, "email": email, "username": username]

                DataService.createNewAccount(user) // Doesnt Work

                }



                //Store UID in NSDefaults so if user reopen app they automatically log in if UID exsisits.
                NSUserDefaults.standardUserDefaults().setValue(result ["uid"], forKey: "uid")

                // Segue New User

                self.performSegueWithIdentifier("newUserSegue", sender: nil)

        }

//已经将UID保存到NSDefaults的用户中的登录

当用户登录或登记时，我打算保存他们的＆＃34; UID＆＃34;到NSDefaults。

然后检查：

override func viewDidAppear(animated: Bool) {
        super.viewDidAppear(animated)

        if NSUserDefaults.standardUserDefaults().valueForKey("uid") != nil {
            self.performSegueWithIdentifier("newUserSegue", sender: nil)
        } else {
            print("User is not registered or has their UID saved to NSDefaults")
        }

    }

这是一种安全的方法吗？

我不认为有必要使用新的Firebase，在显示板中查看，您的所有用户都应位于“验证”标签下，

此新行在新Firebase中没有任何意义，您查询的URL位于您下载的.plist中。

let BASE_URL = "https://project-1321.firebaseio.com" //remove this line

并使用类似

的内容

let firebaseRef = FIRDatabase.database().reference()
let newsRef = firebaseRef.child("news")

您可以在https://firebase.google.com/docs/auth/ios/password-auth#sign_in_a_user_with_an_email_address_and_password

找到许多有用的信息

@brkr在回复上述评论时，您仍然可以使用UID向Firebase数据库添加唯一身份用户。

例如，这是您的用户ref（在DataService类中）： char

现在，在Firebase 3.0中创建一个用户：

let REF_USERS = FIRDatabase.database().referenceFromURL("\(URL_BASE)/users")

创建帐户方法的代码：

FIRAuth.auth()!.createUserWithEmail(email, password: pwd, completion: { authData, error  in
            if error == nil {    
                // Log user in
                FIRAuth.auth()?.signInWithEmail(email, password: pwd) { authData, error in
                    // Save user information to Firebase data
                    let user = // your user Dictionary 
                    DataService.createNewAccount(authData!.uid, user: user)
                }
            } else {
                // Handle login error here
            }
        })

如何在特定的数据库引用中使用FIRApp.createUserWithEmail？
