扩展路由类

public class CustomRoute : RouteBase
{
    /// <summary>
    /// 如果是Chrome/74.0.3729.169 版本，允许正常访问
    /// 否则 跳转提示页
    /// </summary>
    /// <param name="httpContext"></param>
    /// <returns></returns>
    public override RouteData GetRouteData(HttpContextBase httpContext)
    {
        //httpContext.Request.Url.AbsoluteUri
        if (httpContext.Request.UserAgent.Contains("Chrome/74.0.3729.169"))
        {
            return null;//继续后面的
        }
        else
        {
            RouteData routeData = new RouteData(this, new MvcRouteHandler());//还是走mvc流程
            routeData.Values.Add("controller", "pipe");
            routeData.Values.Add("action", "refuse");
            return routeData;//中断路由匹配
        }
    }
    public override VirtualPathData GetVirtualPath(RequestContext requestContext, RouteValueDictionary values)
    {
        return null;
    }
}

public class CustomMvcRouteHandler : MvcRouteHandler
{
    protected override IHttpHandler GetHttpHandler(RequestContext requestContext)
    {
        return new CustomHttpHandler();
    }
}

public class CustomHttpHandler : IHttpHandler
{
    public bool IsReusable => true;

    public void ProcessRequest(HttpContext context)
    {
        context.Response.ContentType = "text/html";
        context.Response.WriteFile(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "Web.config"));
        //看日志
    }
}

在全局路由配置添加如下代码

routes.Add("config", new Route("xt/{path}", new CustomMvcRouteHandler()));
