如何从ISO格式MVC4控制器返回JSON日期 [英] How to return json date from MVC4 controller in ISO format

问题描述

我使用Json.Net从ASP.NET MVC4控制器试图TRO归期ISO格式

I tried tro return date in ISO format using Json.Net from ASP.NET MVC4 controller

public JsonResult Sales() {
  var saleList = new List<Sale>();

  ... 
        var str = JsonConvert.SerializeObject(saleList);
        return Json(str, JsonRequestBehavior.AllowGet);
        }

public class Sale
{
    public DateTime saledate { get; set; }
    ...
}

但它返回整个对象JSON对象作为单个字符串。

But it returns whole object json notation as single string.

推荐答案

您可以用 ServiceStack做JSON序列化，但首先你必须将它集成到ASP.NET MVC。

You can do it with ServiceStack JSON serializer but first you have to integrate it to ASP.NET MVC.

安装包后，在应用程序启动配置日期时间序列化：

After installing the package, configure DateTime serialization in application start:

JsConfig.DateHandler = JsonDateHandler.ISO8601;

有关内容的JSON创建一个ActionResult类型：

Create an ActionResult type for JSON content:

public class CustomJsonResult : ActionResult
{
    private readonly object _data;
    private readonly string _content;
    private readonly Encoding _encoding;

    public CustomJsonResult(object data) : this(data, null, null) { }

    public CustomJsonResult(object data, string content) : this(data, content, null) { }

    public CustomJsonResult(object data, Encoding encoding) : this(data, null, encoding) { }

    public CustomJsonResult(object data, string content, Encoding encoding)
    {
        _data = data;
        _content = content;
        _encoding = encoding;
    }

    public override void ExecuteResult(ControllerContext context)
    {
        if (context == null)
        {
            throw new ArgumentNullException("context");
        }
        HttpResponseBase response = context.HttpContext.Response;
        response.ContentType = string.IsNullOrEmpty(_content) ? "application/json" : _content;

        if (_encoding != null)
        {
            response.ContentEncoding = _encoding;
        }

        response.Write(JsonSerializer.SerializeToString(_data));
    }
}

然后你可以将这些方法添加到主控制器：

Then you can add these methods to a base controller:

protected CustomJsonResult CustomJson(object data)
{
    return new CustomJsonResult(data);
}

protected CustomJsonResult CustomJson(object data, string content)
{
    return new CustomJsonResult(data, content);
}

protected CustomJsonResult CustomJson(object data, Encoding encoding)
{
    return new CustomJsonResult(data, encoding);
}

protected CustomJsonResult CustomJson(object data, string content, Encoding encoding)
{
    return new CustomJsonResult(data, content, encoding);
}

最后，你可以返回这样的结果：

At last you can return the result like this:

return CustomJson(saleList);
