 GlobalConfiguration.Configuration.Formatters.Remove(new XmlMediaTypeFormatter());
            // 解決json序列化時的循環引用問題
            GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings.ReferenceLoopHandling =
                Newtonsoft.Json.ReferenceLoopHandling.Ignore;
            // 對 JSON 數據使用混合大小寫。駝峯式,可是是javascript 首字母小寫形式.
            GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings.ContractResolver =
                new CamelCasePropertyNamesContractResolver();
            //對日期格式進行統一處理
            GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings.Converters.Add(
                new IsoDateTimeConverter()
                {
                    DateTimeFormat = "yyyy-MM-dd HH:mm:ss.fff"
                });
