Mvc4 WepApi空响应时，非200 [英] Mvc4 WepApi Empty Response when non 200

问题描述

当一个Action被调用并抛出一个特定的异常，我使用ExceptionFilterAttribute的错误转化为作为的HTTPStatus code.BadRequest不同的反应。这已在本地工作，但我们把它推到一台服务器，现在当我得到的错误请求我不明白的效应初探任何信息。我缺少什么？

When an Action is called and throws a specific exception, I use an ExceptionFilterAttribute that translate the error into a different response as HttpStatusCode.BadRequest. This has been working locally, but we pushed it to a server and now when I get the BadRequest I do not get any information in the reponse. What am I missing?

    public override void OnException(HttpActionExecutedContext actionExecutedContext)
    {
        MyException ex = actionExecutedContext.Exception as MyException;
        if (ex == null)
        {
            base.OnException(actionExecutedContext);
            return;
        }

        IEnumerable<InfoItem> items = ex.Items.Select(i => new InfoItem
                                                                       {
                                                                           Property = i.PropertyName,
                                                                       Message = i.ToString()
                                                                   });

    actionExecutedContext.Result = new HttpResponseMessage<IEnumerable<InfoItem>>(items, HttpStatusCode.BadRequest);
  }

编辑：当我打的本地服务体是包括在内。看来问题是从远程机器打的服务时。

When I hit the service locally the body is included. It seems the problem is when hitting the service from a remote machine.

推荐答案

试试这个：

GlobalConfiguration.Configuration.IncludeErrorDetailPolicy = 
            IncludeErrorDetailPolicy.Always
