问题描述
我有一个需要添加 Favicon.ico 的网站.该站点是使用带有路由的 ASP.NET 3.5 Web 窗体编写的.问题是 Favicon 链接总是返回一个找不到页面的错误.这是因为路由不知道 Favicon.ico 的链接应该去哪里，所以它返回 Not Found 页面.
I have a website where I need to add a Favicon.ico. The site is written using ASP.NET 3.5 Web Forms with Routing. The issue is that the Favicon link always returns a page not found error. This is because the Routing does not know where the link for Favicon.ico should go to so it returns the Not Found page.
我尝试为网站图标添加 StopRoutingHandler，但它们似乎都不起作用.以下是我迄今为止尝试过的:
I have tried to add a StopRoutingHandler for the the favicon but none of them seem to work. Below are the ones I have tried so far:
routes.Add(new Route("MasterPages/{favicon}.ico", new StopRoutingHandler()));
routes.Add(new Route("{favicon}.ico", new StopRoutingHandler()));
routes.Add(new Route("favicon.ico", new StopRoutingHandler()));
routes.Add(new Route("favicon.ico/{*pathInfo}", new StopRoutingHandler()));
有人知道我应该使用什么吗?我尝试过的 favicon.ico 链接如下所示:
Does anyone know what I should be using? My favicon.ico links I have tried look like this:
<link rel="shortcut icon" href="/favicon.ico" type="image/x-icon" />
<link rel="icon" href="/favicon.ico" type="image/x-icon" />
它们在我的 <html><head> 标签内.
And they are inside of my <html><head> tags.
另外，作为最后一点，我没有使用 MVC，因为如果我可以使用它:
Also, as one final note, I am not using MVC because if I was I could use this:
routes.IgnoreRoute("{*favicon}", new {favicon=@"(.*/)?favicon.ico(/.*)?"});
很遗憾，IgnoreRoute 不适用于路由 Web 表单，因为它不是 MVC 应用程序.
Unfortunately, IgnoreRoute does not work for Routing Web Forms though because it is not an MVC application.
推荐答案
我用过，效果不错:
routes.Add(new Route("favicon.ico", new StaticFileRouteHandler("~/favicon.ico")));
public class StaticFileRouteHandler : IRouteHandler
{
public string VirtualPath { get; set; }
public StaticFileRouteHandler(string virtualPath)
{
VirtualPath = virtualPath;
}
public System.Web.IHttpHandler GetHttpHandler(RequestContext requestContext)
{
HttpContext.Current.RewritePath(VirtualPath);
return new DefaultHttpHandler();
}
}
显然这也有效:
routes.Add(new Route("favicon.ico", new StopRoutingHandler()));
我只需要关闭 Firefox，清除我的历史记录，然后重试.
I just needed to close Firefox, clear my history and try again.
