如何从onException的方法来发送自定义对象？ [英] How to send a custom object from OnException method?

问题描述

public override void OnException(
         System.Web.Http.Filters.HttpActionExecutedContext actionExecutedContext)
    {
        if (actionExecutedContext.Exception != null)
            Elmah.ErrorSignal.FromCurrentContext().Raise(actionExecutedContext.Exception);
        base.OnException(actionExecutedContext);


        throw new HttpResponseException(new HttpResponseMessage(HttpStatusCode.InternalServerError)
        {
            Content = new StringContent(actionExecutedContext.Exception.Message),
            ReasonPhrase = "Deadly Exception",
        });
    }

这是我的模型筛选器传递给任何asp.net网站的API。

This is my filter for Model passed to any asp.net web api.

它的工作原理就像一个魅力！

It works like a charm!

但在我的情况，我要的是返回的自定义对象（奇怪的需要）回用户，如：

But in my case, what I want is to return custom object (strange need) back to user like:

public class ErrorModel
{
   public int StatusCode {get;set;}
   public string ErrorMsg {get;set;}
}

我想要做的是（如果可能的话）：

What I want to do is (if it is possible):

 public override void OnException(
         System.Web.Http.Filters.HttpActionExecutedContext actionExecutedContext)
    {



        ErrorModel er = new ErrorModel(); //////////// object of class


        if (actionExecutedContext.Exception != null)

         er.StatusCode =200
         er.ErrorMsg="My Custom Msg" 

        // return er object 

    }

我想将对象从这个功能，但这种方法的返回类型为无效。

我知道的Htt presponseMessage 对象可后仰，但我想这样做定制的方式...

I know HttpResponseMessage object can be thrown back, but I want to do it customized way...

我该怎么办呢？

推荐答案

我猜你想返回该类作为JSON。

I guess you want to return that class as JSON.

你可以做的仍然是使用的StringContent 的构造函数，但是传递一个JSON序列化的字符串。你可以使用Newtonsoft.Json作为系列化。

What you could do is still use the StringContent constructor, but pass in a JSON serialized string. You could use Newtonsoft.Json as serialized.

throw new HttpResponseException(new HttpResponseMessage(HttpStatusCode.InternalServerError)
{
    Content = new StringContent(JsonConvert.SerializeObject(yourObject))
});
