我正在尝试使用Nancy来获取我的自托管服务,以便在未捕获的异常时返回json格式的错误.但是,我总是得到答复:

{"readyState":4,"status":404,"statusText":"error"}

(以下是整个网络中几个例子的合并).

我的引导程序包含以下内容:

        pipelines.OnError.AddItemToEndOfPipeline((ctx, exc) =>
        {
            if (exc is Exception)
            {
                // this is always executed upon failure to handle an exception.

                Log.Error("Unhandled error on request: " + context.Request.Url + " : " + exc.Message, exc);

                JsonResponse response = new JsonResponse(string.Format("{0}:{1}", exc, exc.Message), new DefaultJsonSerializer());
                response.StatusCode = HttpStatusCode.InternalServerError;

                return response;
            }

            return HttpStatusCode.InternalServerError;
        });

我有一个StatusCodeHandler:

public class JsonErrorStatusCodeHandler : IStatusCodeHandler
{
    public bool HandlesStatusCode(HttpStatusCode statusCode, NancyContext context)
    {
        return statusCode == HttpStatusCode.InternalServerError;
    }


    public void Handle(HttpStatusCode statusCode, NancyContext …
