Question

我自学了一年多以前如何在线编码。我在自己的应用程序上取得了很小的进步。在尝试创建新用户时，我不断收到相同的错误代码。＆＃34; updateChildValues：at / failed：permission_denied＆＃34;下面我将发布我的代码副本，请帮帮我。

@IBAction func btnLogin(_ sender: Any) {
}
@IBOutlet weak var btnLogin: UIButton!
@IBOutlet weak var txtPassword: UITextField!
@IBOutlet weak var txtUserName: UITextField!
@IBAction func Signup(_ sender: UIButton) {
}

if txtUserName.text != "" && txtPassword.text != ""
    {

    }
    Auth.auth().signIn(withEmail: txtUserName.text!, password: txtPassword.text!) { (user, error) in
        if user != nil
        {
            //Sign in successful
            self.performSegue(withIdentifier: "segue", sender: self)
        }
        else
        {

        }

       if let myError = error?.localizedDescription
       {
        print(myError)
        }
       else{
        print("Error")
        }
    }

    let ref =  Database.database().reference(fromURL: "https://odd-jobs-llc.firebaseio.com/")
    observeKeyboardNotifications()

    ref.updateChildValues(["Customers": 123123])
}

请帮我克服这堵砖墙。我真的很感激。谢谢你有一个美好的夜晚扎克

试试这个

@IBOutlet weak var btnLogin: UIButton!
@IBOutlet weak var txtPassword: UITextField!
@IBOutlet weak var txtUserName: UITextField!



// Assuming this is the button you want to tap to signup the user
@IBAction func Signup(_ sender: UIButton) {

    if txtUserName.text != "" && txtPassword.text != "" {
      Auth.auth().createUser(withEmail: txtUserName.text!, password: txtPassword.text!) { (user, error) in
          if user != nil {
              print("Registration success! Now I can do whatever I want in this block")
          } else {
             // telling you what went wrong
             print(error?.localizedDescription)
          }
      }
    } else {
      print("One of your field is empty")
    }

@IBAction func btnLogin(_ sender: Any) {

    if txtUserName.text != "" && txtPassword.text != "" {
       Auth.auth().signIn(withEmail: txtUserName.text!, password: txtPassword.text!) { (user, error) in

        if user != nil {
            //Sign in successful
            let ref =  Database.database().reference(fromURL: "https://odd-jobs-llc.firebaseio.com/")
            observeKeyboardNotifications()
            ref.updateChildValues(["Customers": 123123])
            self.performSegue(withIdentifier: "segue", sender: self)

        } else {

           if let myError = error?.localizedDescription {
               print(myError)
           } else{
               print("Error")
           }
        }


    }

   }
}

请参阅Firebase quickstart

默认情况下，数据库只能由经过身份验证的用户读取/写入。您必须允许对数据库进行未经身份验证的访问。

无法使用firebase创建新用户。我一直收到错误消息＆＃34; updateChildValues：at / failed：permission_denied＆＃34;
