blocks|key|123036|text|我用这种方式简单而优雅。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|123037|public+ActionResult+Validate(User+user)

I use this way simple and elegant.

<pre><code>public ActionResult Validate(User user)
{
 return new HttpStatusCodeResult((HttpStatusCode)500, 
 "My custom internal server error.");
}
</code></pre>

Then angular controller.

<pre><code>function errorCallBack(response) { 
$scope.response = {
 code: response.status,
 text: response.statusText
}}); 
</code></pre>

Hope it helps you.

blocks|key|123062|text|另一个简化的例子：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|123063|public+class+MyController+:+ApiController
{
++++public+IHttpActionResult+Get()
++++{
++++++++HttpStatusCode+codeNotDefined+=+(HttpStatusCode)422;
++++++++return+Content(codeNotDefined,+"message+to+be+sent+in+response+body");
++++}
}|code-block|syntax|javascript|123064|Content是在抽象类ApiController中定义的虚拟方法，该类是控制器的基础。声明如下：|offset|length|style|CODE|123065|protected+internal+virtual+NegotiatedContentResult<T>+Content<T>(HttpStatusCode+statusCode,+T+value);|123066|entityMap^0|0|0|0|7|C|D|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|S|8|@$I|T|J|U|K|L]|$I|V|J|W|K|L]]|9|@]|A|$]]|$1|M|3|N|5|D|7|X|8|@]|9|@]|A|$E|F]]|$1|O|3|-4|5|6|7|Y|8|@]|9|@]|A|$]]]|P|$]]

Another simplified example:

<pre><code>public class MyController : ApiController
{
 public IHttpActionResult Get()
 {
 HttpStatusCode codeNotDefined = (HttpStatusCode)422;
 return Content(codeNotDefined, "message to be sent in response body");
 }
}
</code></pre>

<code>Content</code> is a virtual method defined in abstract class <code>ApiController</code>, the base of the controller. See the declaration as below:

<pre><code>protected internal virtual NegotiatedContentResult&lt;T&gt; Content&lt;T&gt;(HttpStatusCode statusCode, T value);
</code></pre>

blocks|key|4629150|text|我在我的控制器中使用了一个自定义过滤器，它可以捕获任何异常并返回自定义错误结果，因此我需要一种方法来根据异常消息返回自定义消息响应。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4629151|我使用JsonResult+(在Microsoft.AspNetCore.Mvc名称空间中找到)返回自定义状态代码和消息，如下所示：|offset|length|4629152|public+class+DomainViolationFilter+:+ExceptionFilterAttribute

I'm using a custom Filter in my controllers that catches any exceptions and returns custom error results so I needed a way to return a custom message response based on the exception message.

I'm using <a href="https://docs.microsoft.com/en-us/dotnet/api/microsoft.aspnetcore.mvc.jsonresult?view=aspnetcore-3.0" rel="nofollow noreferrer">JsonResult</a> (found in the Microsoft.AspNetCore.Mvc namespace) to return a custom status code and messagesas such:

<pre><code>public class DomainViolationFilter : ExceptionFilterAttribute
 {
 public override void OnException(ExceptionContext context)
 {
 switch (context.Exception)
 {
 case EntityNotFoundException e:
 JsonResult toReturn = new JsonResult(e);
 toReturn.StatusCode = 404;
 context.Result = toReturn;
 return;
 }
 }
 }
</code></pre>

In my case, I'm serializing directly the exception object (ex) for simplicity but you should be returning only the relevant (and safe) data, or whatever you need in your use case.

I'm working on a service in WebAPI 2, and the endpoint currently returns an <code>IHttpActionResult</code>. I'd like to return a status code <code>422</code>, but since it's not in the <code>HttpStatusCode</code> enumeration, I'm at a loss as to how it would be sent, since all of the constructors require a parameter of <code>HttpStatusCode</code>

As it stands now, I'm returning <code>BadResult(message)</code>, but returning a <code>422</code> + message would be more descriptive and useful for my clients. Any ideas?

Return Custom HTTP Status Code from WebAPI 2 endpoint

我正在处理WebAPI 2中的一个服务，端点当前返回一个IHttpActionResult。我想返回一个状态代码422，但是因为它不在HttpStatusCode枚举中，所以我不知道如何发送它，因为所有的构造函数都需要一个HttpStatusCode参数现在，我返回的是BadResult(message)，但是返回42...
