最近项目中前台页面使用EasyUI的jQuery插件开发中遇到,EasyUI Form中的Datebox组件绑定ASP.NET MVC返回的DateTime类型的数据错误,因为ASP.NET MVC返回的DateTime类型的JsonResult的结果中的值是"\/Date(277630788015)\/",于是EasyUI显示的就是返回的值,没有将日期转换,直接显示在DateBox组件中,解决这个问题其实有两种办法:
首先看下ASP.NET MVC中的Controller的 Json方法的源码:
protected internal JsonResult Json(object data) {
return Json(data, null /* contentType */);
}
protected internal JsonResult Json(object data, string contentType) {
return Json(data, contentType, null /* contentEncoding */);
}
protected internal virtual JsonResult Json(object data, string contentType, Encoding contentEncoding) {
return new JsonResult {
Data = data,
ContentType = contentType,
ContentEncoding = contentEncoding
};
}
可以看出关键还是在JsonResult这个结果类中,JsonResult类的源码如下:
[AspNetHostingPermission(System.Security.Permissions.SecurityAction.LinkDemand, Level = AspNetHostingPermissionLevel.Minimal)]
[AspNetHostingPermission(System.Security.Permissions.SecurityAction.InheritanceDemand, Level = AspNetHostingPermissionLevel.Minimal)]
public class JsonResult : ActionResult {
public Encoding ContentEncoding {
get;
set;
}
public string ContentType {
get;
set;
}
public object Data {
get;
set;
}
public override void ExecuteResult(ControllerContext context) {
if (context == null) {
throw new ArgumentNullException("context");
}
HttpResponseBase response = context.HttpContext.Response;
if (!String.IsNullOrEmpty(ContentType)) {
response.ContentType = ContentType;
}
else {
response.ContentType = "application/json";
}
if (ContentEncoding != null) {
response.ContentEncoding = ContentEncoding;
}
if (Data != null) {
#pragma warning disable 0618
JavaScriptSerializer serializer = new JavaScriptSerializer();
response.Write(serializer.Serialize(Data));
#pragma warning restore 0618
}
}
}
}
看到这里大家应该明确我们的修改目标了,对,就是ExecuteResult这个方法,这个方法是序列化Data对象为Json格式的,可见ASP.NET MVC 使用的是System.Web.Script.Serialization.JavaScriptSerializer类
既然明确了目标,那么就开始动手吧。
1. 扩展JsonResult类自定义个CustomJsonResult类,重写ExecuteResult方法代码如下:
public class CustomJsonResult:JsonResult
{
public override void ExecuteResult(ControllerContext context)
{
if (context == null)
{
throw new ArgumentNullException("context");
}
HttpResponseBase response = context.HttpContext.Response;
if (!String.IsNullOrEmpty(ContentType))
{
response.ContentType = ContentType;
}
else
{
response.ContentType = "application/json";
}
if (ContentEncoding != null)
{
response.ContentEncoding = ContentEncoding;
}
if (Data != null)
{
#pragma warning disable 0618
response.Write(JsonConvert.SerializeObject(Data));
#pragma warning restore 0618
}
}
public class BaseController:Controller
{
protected override JsonResult Json(object data, string contentType, Encoding contentEncoding)
{
return new CustomJsonResult
{
Data = data,
ContentType = contentType,
ContentEncoding = contentEncoding
};
}
}
下面就是我们实际使用方法了,因为Newtonsoft.Json.JsonConvert类DateTime类型可以指定序列化日期的类型为: [JsonConverter(typeof(IsoDateTimeConverter))], [JsonConverter(typeof(JavaScriptDateTimeConverter))]
[JsonConverter(typeof(IsoDateTimeConverter))]序列化后的格式为:1981-03-16T00:20:12.1875+08:00
[JsonConverter(typeof(JavaScriptDateTimeConverter))]序列化后的格式为:new Date(-277630787812)
于是我们指定实体类的DateTime属性为IsoDateTimeConverter,代码如下:
[Field("P_Date", "更新日期")]
[JsonConverter(typeof(IsoDateTimeConverter))]
public DateTime P_Date { get; set; }
控制器继承自BaseController,Action的返回结果还是JsonResult格式,代码如下:
public class GoodsController:BaseController
{
public JsonResult List(string page, string rows)
{
Page thepage = new Page() { PageSize = 20, CurrentPage = 1 };
if (!String.IsNullOrEmpty(rows))
{
thepage.PageSize = Convert.ToInt32(rows);
}
if (!String.IsNullOrEmpty(page))
{
thepage.CurrentPage = Convert.ToInt32(page);
}
Dictionary<string, object> result = new Dictionary<string, object>();
result.Add("rows", new BusinessLogic().SelectByPage<GoodsList>(ref thepage));
result.Add("total", thepage.SumCount);
return Json(result);
}
}
