mvc 使用json.net 替换JsonResult 默认序列化

默认mvc json序列化 机制处理日期等字段时 格式并不是我们想要的格式

我们可以使用json.net 覆盖mvc默认的序列化行为

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Web;
using System.Web.Mvc;
using Newtonsoft.Json;

namespace Ecomm.Common.Web.Result
{
    /// <summary>
    /// 覆盖默认  JsonResult 中JavascriptSerializer 序列化json 改用 json.net 序列化对象。处理日期问题
    /// </summary>
    public class JsonNetResult : JsonResult
    {
        public JsonNetResult()
        {
            Settings = new JsonSerializerSettings
            {
                ReferenceLoopHandling = ReferenceLoopHandling.Error
            };
        }

        public JsonSerializerSettings Settings { get; private set; }

        public override void ExecuteResult(ControllerContext context)
        {
            if (context == null)
                throw new ArgumentNullException("context");
            if (this.JsonRequestBehavior == JsonRequestBehavior.DenyGet && string.Equals(context.HttpContext.Request.HttpMethod, "GET", StringComparison.OrdinalIgnoreCase))
                throw new InvalidOperationException("JSON GET is not allowed");

            HttpResponseBase response = context.HttpContext.Response;
            response.ContentType = string.IsNullOrEmpty(this.ContentType) ? "application/json" : this.ContentType;

            if (this.ContentEncoding != null)
                response.ContentEncoding = this.ContentEncoding;
            if (this.Data == null)
                return;

            var scriptSerializer = JsonSerializer.Create(this.Settings);

            using (var sw = new StringWriter())
            {
                scriptSerializer.Serialize(sw, this.Data);
                response.Write(sw.ToString());
            }
        }
    }
}

可以在baseController中覆盖默认 序列化行为

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
using System.Web;
using System.Web.Mvc;
using System.Data;
using Newtonsoft.Json;

namespace Ecomm.Mvc.Web.Controllers
{
    public  class BaseController:Controller
    {
        //
        // GET: /Base/
        // 项目都继承 Base 以后可以在这里扩展统一方法

        /// <summary>
        /// 覆盖重载默认的 JsonResult 序列化json 逻辑 改用json.net 引擎序列化对象 
        /// 解决 日期格式等问题
        /// </summary>
        /// <param name="data"></param>
        /// <param name="contentType"></param>
        /// <param name="contentEncoding"></param>
        /// <param name="behavior"></param>
        /// <returns></returns>
        protected override JsonResult Json(object data, string contentType,
       Encoding contentEncoding, JsonRequestBehavior behavior)
        {
            return new JsonNetResult
            {
                Data = data,
                ContentType = contentType,
                ContentEncoding = contentEncoding,
                JsonRequestBehavior = behavior
            };
        }
        /// <summary>
        /// controller action 执行之前执行
        /// </summary>
        /// <param name="filterContext"></param>
        protected override void OnActionExecuting(ActionExecutingContext
           filterContext)
        {
           //todo 在默认action 被执行前可以做的事情...

        }
    }
}

也可以在JsonResult 中手动调用
