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     }
52 }

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>

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 }
