Answer 1

感謝您的答覆，但最終的解決方案

class HttpRequest<Request, Response> 
{ 
    private var serviceBase:String = "http://192.168.1.1/api"; 
    func request(path:String, model: Request, success: @escaping((_ response: [Response]?) ->()), failure: @escaping ((_ error:String) ->()) { 
     // code here.. 
    } 
} 

Answer 2

你可以只通過關閉（功能）作爲參數

swift 
func request(requestPath:String, requestParams:Any, callback:((Result) -> Void)) { 
    ... 
} 

其中Result將是您回覆的類型。
