斯威夫特4 - 我怎么能得到一个结果（字典和数据）typealias的完成处理程序帮助

Question

我在与typealias完成处理程序有点困惑

我创建了一个typealias具有结果，状态数据。这里是我正在创建它：

typealias Success = (_ result:Dictionary<String, Any>, _ Status:Bool,_ Data:Data) -> Void

我有一个方法与URL，帕拉姆，故障警报和完成handler.I有typealias传递到完成处理器。这里是方法

private func callApi(apiURL:ApiURL, param:[String: Any]?, failAlert:Bool, completionHandler: @escaping Success) {

        var url = "\(AppBaseUrl)\(apiURL.rawValue)"

        var params:[String:Any] = [:]
        var methods:HTTPMethod = .get
        if param != nil {
            params = param!
            methods = .post
            self.printParam(param: params)
        }
        self.apiCallKR(url: url, methods: methods, params: params, failAlert: failAlert, completionHandler: Success)
    }

我得到的错误是这样

无法将类型“Success.Type”的值（又名“（（词典，布尔，数据） - >（））类型”

如何通过completionHandler（KRResult.result，KRResult.Status，response.data！）成功Typealias

func apiCallKR(url:String, methods:HTTPMethod, params:[String:Any],  failAlert:Bool, completionHandler: @escaping Success) {
         let header = ["User-ID":Extensions.getUserID(),"Auth-Key":Extensions.getToken()]

        Alamofire.request(url, method: methods, parameters: params, encoding: URLEncoding.default, headers: header).responseJSON { (response) in
            KRLog("Response: \n\(response)")

            let statusCode = response.response?.statusCode
            switch response.result {
            case .success:
                if statusCode == 200, let json = response.result.value as? [String: Any] {
                   AppDetail.stopIndicator()
                    let KRResult =  self.jsonResponseValidation(sender: json, failAlert: failAlert)
                    completionHandler(KRResult.result, KRResult.Status,response.data!)

                }else {
                    completionHandler([:], false, response.data!)
                    AppDetail.stopIndicator()
                    AppDetail.showToast(toastText: AlertText(.textAlertJsonFormatMismatch), type: .fail, handler: nil)
                }
}
}
}

尝试

self.apiCallKR(url: url, methods: methods, params: params, failAlert: failAlert, completionHandler: completionHandler)
