如何在 HandleUnauthorizedRequest 中输出默认的 404 页面

发布于 2024-10-14 11:10:49 字数 644 浏览 5 评论 0原文

我编写了一个自定义 AuthorizeAttribute，它覆盖了 HandleUnauthorizedRequest。此覆盖有条件地将响应状态代码设置为 404：

var response = filterContext.HttpContext.Response;
response.StatusCode = 404;
response.ContentType = null;
response.End();

问题是完整响应是：

HTTP/1.1 404 Not Found
Server: ASP.NET Development Server/10.0.0.0
Date: Mon, 24 Jan 2011 16:43:08 GMT
X-AspNet-Version: 4.0.30319
X-AspNetMvc-Version: 2.0
Cache-Control: private
Connection: Close

当我想发回默认 404 页面时。例如：

我该怎么做？

原文

I have written a custom AuthorizeAttribute having an override of HandleUnauthorizedRequest. This override conditionally sets the response status code to 404 with:

var response = filterContext.HttpContext.Response;
response.StatusCode = 404;
response.ContentType = null;
response.End();

The problem is that the full response is:

HTTP/1.1 404 Not Found
Server: ASP.NET Development Server/10.0.0.0
Date: Mon, 24 Jan 2011 16:43:08 GMT
X-AspNet-Version: 4.0.30319
X-AspNetMvc-Version: 2.0
Cache-Control: private
Connection: Close

when I would like to send back the default 404 page. Something like:

How do I do that?

怎么样：
在 Web.config 中创建自定义 404 处理程序，如下所示：

<customErrors mode="On">
<error statusCode="404" redirect="My404ErrorPage.aspx" />
</customErrors>

现在所有 404 错误都转到 My404ErrorPage.aspx（或您选择的任何名称）
你的错误页面），你也可以随意重定向到它。

也许“Response.WriteError(404);

What about:
Create a custom 404 handler in Web.config as follows:

<customErrors mode="On">
<error statusCode="404" redirect="My404ErrorPage.aspx" />
</customErrors>

Now all 404 errors go to My404ErrorPage.aspx (or whatever you choose to name
your error page) and you can also redirect to it at will.

Maybe "Response.WriteError(404);

我最终做的是设置 过滤器上下文的 Result 属性如下所示：

var response = filterContext.HttpContext.Response;
response.StatusCode = 404;
var viewData = new ViewDataDictionary();
viewData["Id"] = filterContext.HttpContext.Request.RequestContext.RouteData.Values["id"];
filterContext.Result = new ViewResult { ViewName = "NotFound", ViewData = viewData };
return;

其中“NotFound”是控制器的一个操作，其中包含用我的自定义 AuthorizeAttribute 标记的不同操作。

What I ended up doing is setting the Result property of the filter context like this:

var response = filterContext.HttpContext.Response;
response.StatusCode = 404;
var viewData = new ViewDataDictionary();
viewData["Id"] = filterContext.HttpContext.Request.RequestContext.RouteData.Values["id"];
filterContext.Result = new ViewResult { ViewName = "NotFound", ViewData = viewData };
return;

where "NotFound" is an action of the controller containing a different action that was marked with my custom AuthorizeAttribute.
