你怎么扔的Htt presponseException在ASP 5（vnext） [英] How do you throw HttpResponseException in ASP 5 (vnext)

问题描述

我写在ASP 5.我想返回错误请求code异常，如果传递给服务的参数不正确的API控制器。在的WebAPI的当前版本中，我会做：

I'm writing an api controller in ASP 5. I want to return a bad request code exception if the parameters passed to the service are incorrect. In the current version of webapi I would do:

throw new HttpResponseException(HttpStatusCode.BadRequest);

但的Htt presponseException 是的System.Web 的一部分，它已经从ASP 5删除，因此，我不能再实例化。

However HttpResponseException is part of System.Web, which has been removed from ASP 5 and thus I cannot instantiate it anymore.

什么是vNext这样做的正确方法？

What is the proper way to do this in vNext?

推荐答案

要回答你的问题，你可以使用的 WebApiCompatibilityShim 哪些端口的Htt presponseException （和许多其他功能）迈进MVC 6.（感谢DWright的链接<一个href=\"http://www.strathweb.com/2015/01/migrating-asp-net-web-api-mvc-6-exploring-web-api-compatibility-shim/\"相对=nofollow>这篇文章。）

To answer your question, you can use the WebApiCompatibilityShim which ports HttpResponseException (and many other features) forward into MVC 6. (thanks to DWright for the link to that article.)

好像要做到这一点是从你的方法返回一个IActionResponse，然后再调用MVC-6路 HttpBadRequest（）这是基本<$上的方法C $ C> Microsoft.AspNet.Mvc.Controller 类，它返回一个 BadRequestResult ，我相信是获得400进入状态的最佳方式响应

It seems like the MVC-6 way to do it is to return an IActionResponse from your method and then call HttpBadRequest() which is a method on the base Microsoft.AspNet.Mvc.Controller class that returns an BadRequestResult, which I believe is the best way to get a 400 status into the response.

的控制器类有其他响应codeS以及方法 - 包括 HttpNotFound（）方法这会导致404要返回。

The Controller class has methods for other response codes as well - including the HttpNotFound() method which causes a 404 to be returned.
