设置Context.Response.StatusCode似乎不起作用

http-status-codes http .net c#

我有一个HttpHandler,代码如下:

using System;
using System.Web;
using Company.Cms;
using Company.Web.Handlers.Console;


namespace Company.Web.Handlers
{
    /// <summary>
    /// Summary description for AdminHandler
    /// </summary>
    public class AdminHandler : IHttpHandler
    {
        public bool IsReusable
        {
            get
            {
                return false;
            }
        }

        public void ProcessRequest(HttpContext context)
        {
            HttpRequest request = context.Request;
            HttpResponse response = context.Response;
            string action = request.QueryString["action"];

            if (!HttpContext.Current.User.CanAdminister())
            {
                response.StatusCode = 403;
                response.Status = "403 Access Denied";
                response.End();
                return;
            }

            if (String.IsNullOrEmpty(action))
            {
                response.StatusCode = 404;
                response.Status = "404 Not Found";
                response.End();
                return;
            }

            IHttpHandler handler = null;
            switch (action)
            {
                case "menu":
                    handler = new MenuHandler();
                    break;
                case "tree":
                    handler = new TreeHandler();
                    break;
                case "grid":
                    handler = new GridHandler();
                    break;
                case "list":
                    handler = new ListHandler();
                    break;
                case "drop":
                    handler = new DropHandler();
                    break;
                case "edit":
                    handler = new EditHandler();
                    break;
                case "new":
                    handler = new InsertHandler();
                    break;
            }
            if (handler == null)
            {
                response.StatusCode = 404;
                response.Status = "404 Not Found";
                response.End();
            }
            else
            {
                handler.ProcessRequest(context);
            }
        }
    }
}

不幸的是,当我故意指定一个无效的操作时,浏览器只显示一个空白页。在Firefox和IE中都会显示非浏览器错误消息。

我会做错什么?

Firebug显示正确的状态。做这意味着如果我想要浏览器要显示消息,我必须渲染是我自己吗?

当然了。浏览器根据收到的错误代码执行的操作取决于浏览器。但是您仍然可以提供HTML来支持404。举个例子。。。看一看 Stack Overflow's 404 page . 这个错误消息完全是手工制作的。

先试试这个:

protected void Page_Load(object sender, EventArgs e)
{
    Response.StatusCode = 404;
    Response.SuppressContent = true;
    HttpContext.Current.ApplicationInstance.CompleteRequest();
}

Response.TrySkipIisCustomErrors = true;

301重定向使用 Response.RedirectPermanent() .

对于302重定向,请使用 Response.Redirect()

        if (isPermanentRedirect)
        {
            // 301 Redirect
            args.HttpContext.Response.RedirectPermanent(targetUrl);
        }
        else
        {
            // 302 Redirect
            args.HttpContext.Response.Redirect(targetUrl);
        }
