WEBAPI上实现序列化为JSON，camel驼峰，及格式化日期

在webapiConfig.cs

加上以下代码作为配置：

            //实现序列化为JSON

            GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings.Converters.Add(new IsoDateTimeConverter {

                DateTimeFormat = "yyyy'-'MM'-'dd' 'HH':'mm':'ss"

            });

            GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings.ContractResolver =

                new CamelCasePropertyNamesContractResolver();

Controller调用：

                return Json<dynamic>(new {

                    success = true,

                    msg = "OK",

                    profits = mypf

                }, GlobalConfiguration.Configuration.Formatters.JsonFormatter.SerializerSettings);
