如何在Alamofire中使用POST命令發送此JSON對象？

Question

我從我的iOS應用中的文本框中獲取兩個字段，並且想要將以下JSON對象發送回服務器（使用AlamoFire）當用戶輸入用戶名和密碼時，應將此數據作爲JSON對象發送回到服務器。 我應該如何編寫用於發送此特定JSON對象的POST方法？ 我的JSON如下：

{ "settings": 
     { 
      "username": "myUserName", 
      "password": "myPassword123" 
     } 
    } 

這是我在斯威夫特3類，

class logIN { 

    let username: String! = nil 
    let password: String! = nil 

init(ssid: String, password: String) { 

    let parameters: [String: String] = [ 
      "username": ssid as String, 
      "password": password as String 
     ] 

    var statusCode: Int = 0 
    Alamofire.request("URL_HERE", parameters: parameters) 
     .responseJSON { response in 
      statusCode = (response.response?.statusCode)! 
      print(String(statusCode)) 

     } 
    } 
} 

這是我完成按鈕，點擊它會發送POST請求時IBAction爲。

@IBAction func doneButton(_ sender: Any) { 
    let logInInstance = logIN(ssid : self.username.text!, password : self.password.text!) 

}

let loginParam: [String: String] = [ 
       "username": ssid as String, 
       "password": password as String 
      ] 

    var parameters = [String:Any]() 
    parameters["setting"] = loginParam 

    var statusCode: Int = 0 
    Alamofire.request("URL_HERE", parameters: parameters) 
     .responseJSON { response in 
      statusCode = (response.response?.statusCode)! 
      print(String(statusCode)) 

     } 
    }
