Nancy异步用法

个人笔记，记录Nancy异步用法

基类，所有请求都将首先执行该类，并执行Before事件

namespace CxyAdvert.Base
{
    public class BaseNancyModel : Nancy.NancyModule
    {
        public BaseNancyModel()
        {
            Get["/"] = param =>
            {
                return "ADVERT SYSTEM";
            };
        }
        public BaseNancyModel(string path)
            : base(path)
        {
            Before += async (context, token) =>
            {
                return await VerifyAuth(context);
            };

            //After += async (context, token) =>
            //{
            //    await VerifyAuth(context);
            //};
        }

　　　　　/// <summary>
        /// Before执行的函数,返回null将继续执行路由指定接口，返回Response将结束并返回
        /// </summary>
        /// <param name="nancyContext"></param>
        /// <returns></returns>
        private async Task<Response> VerifyAuth(Nancy.NancyContext nancyContext)
        {
            try
            {
                var httpMethod = nancyContext.Request.Method;
                if (httpMethod.ToUpper() == "POST")
                {
                    var requestParms = HttpHelper.GetPostValue(nancyContext.Request.Body);
                    if (requestParms == "")
                    {
                        return Response.AsJson(new ResultMsg() { code = -2, errormsg = "参数值不能为空" });
                    }
                    else
                    {
                       
                    }
                }
                return null;
            }
            catch (Exception error)
            {
                Logger.Error("BaseNancyModel ERROR：" + error);
                return Response.AsJson(new ResultMsg() { code = -2, errormsg = error.Message });
            }
        }

　　　　　public object GetEncryptValue(object msg)
        {
            var strJson = JsonConvert.SerializeObject(msg, StringFormat.jsonSerializerSettings);
            return strJson ;
        }
    }
}

接口类，所有接口类继承基类BaseNancyModel，GetEncryptValue函数实现于基类BaseNancyModel中

namespace CxyAdvert
{
    public class AdvertSericeApi : BaseNancyModel
    {
        public AdvertSericeApi() :
            base("/cxy/api/advert/")
        {
            IAdvertSerice service = new AdvertSerice();

            Post["getshowadverts", true] = async (param, token) =>
            {
                return GetEncryptValue(await service.GetShowAdverts(BaseInputParam, ThridUser));
            };

            Post["getadverts", true] = async (param, token) =>
            {
                return GetEncryptValue(await service.GetAdverts(BaseInputParam, ThridUser));
            };
        }
    }
}
