ios - 如何在 Swift 中将注册用户写入数据库？

Question

当我选择 register.. 数据被发送到 Firebase 身份验证但不存储在数据库中？谁能告诉我哪里出错了？

func handleRegister(){
        // Validation
        guard let email = emailTextField.text, let password = PassTextField.text, let name = nameTextField.text
        else{
            print("Please provide an Email and Password")
            return
        }

        FIRAuth.auth()?.createUser(withEmail: email, password: password, completion: { (user: FIRUser?, error) in

            if error != nil {
                print(error!)
                return
            }
            // Successfully authenticated user
            // Saving Data to the Database
            let ref = FIRDatabase.database().reference(fromURL: "https://chat-47e5b.firebaseio.com/")
            let values = ["name": name, "email": email]
            ref.updateChildValues(values, withCompletionBlock: { (err,ref)
                in

                if err != nil {
                    print(err!)
                    return
                }

                print("Saved user successfully into Firebase")
            })
       })
}

你做的不对，你应该首先获得对数据库的引用:

self.ref = FIRDatabase.database().reference()

然后:

let values = ["name": name, "email": email]
self.ref.child("users").child(user.uid).setValue(values)

作为旁注，将其转换为:

if error != nil {
   print(error!)
   return
}

对此:

guard let error = error else {
   print(error)
   return
}
