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

 

 1 using System;

 2 using System.Collections.Generic;

 3 using System.IO;

 4 using System.Linq;

 5 using System.Text;

 6 using System.Threading.Tasks;

 7 using System.Web;

 8 using System.Web.Mvc;

 9 using Newtonsoft.Json;

10 

11 namespace Ecomm.Common.Web.Result

12 {

13     /// <summary>

14     /// 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

15     /// </summary>

16     public class JsonNetResult : JsonResult

17     {

18         public JsonNetResult()

19         {

20             Settings = new JsonSerializerSettings

21             {

22                 ReferenceLoopHandling = ReferenceLoopHandling.Error

23             };

24         }

25 

26         public JsonSerializerSettings Settings { get; private set; }

27 

28         public override void ExecuteResult(ControllerContext context)

29         {

30             if (context == null)

31                 throw new ArgumentNullException("context");

32             if (this.JsonRequestBehavior == JsonRequestBehavior.DenyGet && string.Equals(context.HttpContext.Request.HttpMethod, "GET", StringComparison.OrdinalIgnoreCase))

33                 throw new InvalidOperationException("JSON GET is not allowed");

34 

35             HttpResponseBase response = context.HttpContext.Response;

36             response.ContentType = string.IsNullOrEmpty(this.ContentType) ? "application/json" : this.ContentType;

37 

38             if (this.ContentEncoding != null)

39                 response.ContentEncoding = this.ContentEncoding;

40             if (this.Data == null)

41                 return;

42 

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

44 

45             using (var sw = new StringWriter())

46             {

47                 scriptSerializer.Serialize(sw, this.Data);

48                 response.Write(sw.ToString());

49             }

50         }

51     }

可以在baseController中覆盖默认 序列化行为

 1 using System;

 2 using System.Collections.Generic;

 3 using System.IO;

 4 using System.Linq;

 5 using System.Text;

 6 using System.Web;

 7 using System.Web.Mvc;

 8 using System.Data;

 9 using Newtonsoft.Json;

10 

11 namespace Ecomm.Mvc.Web.Controllers

12 {

13     public  class BaseController:Controller

14     {

15         //

16         // GET: /Base/

17         // 项目都继承 Base 以后可以在这里扩展统一方法

18 

19         /// <summary>

20         /// 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 

21         /// 解决 日期格式等问题

22         /// </summary>

23         /// <param name="data"></param>

24         /// <param name="contentType"></param>

25         /// <param name="contentEncoding"></param>

26         /// <param name="behavior"></param>

27         /// <returns></returns>

28         protected override JsonResult Json(object data, string contentType,

29        Encoding contentEncoding, JsonRequestBehavior behavior)

30         {

31             return new JsonNetResult

32             {

33                 Data = data,

34                 ContentType = contentType,

35                 ContentEncoding = contentEncoding,

36                 JsonRequestBehavior = behavior

37             };

38         }

39         /// <summary>

40         /// controller action 执行之前执行

41         /// </summary>

42         /// <param name="filterContext"></param>

43         protected override void OnActionExecuting(ActionExecutingContext

44            filterContext)

45         {

46            //todo 在默认action 被执行前可以做的事情...

47 

48         }

49     }

50 }

也可以在JsonResult 中手动调用
