## 需要的引用的dll类： ##

Newtonsoft.Json.dll、System.Net.Http.dll、System.Net.Http.Formatting.dll

# Web Api接口为GET形式： #

public static CstyleCmappListRespDTO GetCstyleCmappList(string cstylename, string cmappgname)
            {
                CstyleCmappListRespDTO RespDTO = new CstyleCmappListRespDTO();
                var url = string.Empty;
                try
                {
                    url = RequestUrl + "/dw/get_cstylecmappg_info_dw?id={0}&key={1}×tamp={2}&cstylename={3}&cmappgname={4}";
                    url = string.Format(url, id, key, DateTime.Now.ToString("yyyyMMddHHmmss"), cstylename, cmappgname);
                    var httpClient = new HttpClient();
                    HttpResponseMessage response = httpClient.GetAsync(new Uri(url)).Result;
                    RespDTO = response.Content.ReadAsAsync<CstyleCmappListRespDTO>().Result;
                }
                catch (Exception ex)
                {
                    
                }
                return RespDTO;
            }

# Web Api接口为POST形式： #

public static FlightsResponse QueryFlightPost(FlightQueryRequest ReqDTO)
            {
                FlightsResponse FlightsRespDTO = new FlightsResponse();
                try
                {
                    string requestDTO = JsonConvert.SerializeObject(ReqDTO);
                    MediaTypeFormatter jsonFormatter = new JsonMediaTypeFormatter();
                    HttpContent httpContent = new ObjectContent<FlightQueryRequest>(ReqDTO, jsonFormatter);
                    var url = RequestUrl + "/QueryFlight";
                    var httpClient = new HttpClient(new RequestHandler() { InnerHandler = new HttpClientHandler() });
                    httpClient.Timeout = TimeSpan.FromMinutes(3);
                    var responseJson = httpClient.PostAsync(url, httpContent).Result;
                    FlightsRespDTO = responseJson.Content.ReadAsAsync<FlightsResponse>().Result;
                    
                }
                catch (Exception)
                {
                    FlightsRespDTO = new FlightsResponse();
                }
                return FlightsRespDTO;
            }
