webapi jsonp处理

jsonp只支持httpget请求。

        [HttpGet]
        public ResultObject SubmitOrderJsonp(string gameAccount, string callback)
        {
            T_DTO_CardOrder.AddOrderRequest sOrder = new T_DTO_CardOrder.AddOrderRequest();var a = SubmitOrder(sOrder);

            return a;
        }

Global文件处理：

            GlobalConfiguration.Configuration.AddJsonpFormatter(GlobalConfiguration.Configuration.Formatters.JsonForma‌​tter, "callback");
