Я использую следующий код для своих сайтов MVC 2:
// The legacy route class that exposes a RedirectActionName
public class LegacyRoute : Route
{
public LegacyRoute(string url, string redirectActionName, IRouteHandler routeHandler)
: base(url, routeHandler)
{
RedirectActionName = redirectActionName;
Defaults = new RouteValueDictionary(new { controller = "Home", action = "Index"}); // is not actually called
}
public string RedirectActionName { get; set; }
}
// The legacy route handler, used for getting the HttpHandler for the request
public class LegacyRouteHandler : MvcRouteHandler
{
protected override IHttpHandler GetHttpHandler(RequestContext requestContext)
{
requestContext.HttpContext.Response.Write("success");
return new LegacyHandler(requestContext);
}
}
// The legacy HttpHandler that handles the request
public class LegacyHandler : MvcHandler
{
public LegacyHandler(RequestContext requestContext) : base(requestContext)
{
requestContext.HttpContext.Response.Write("success");
ProcessRequest(requestContext.HttpContext);
}
protected override void ProcessRequest(HttpContextBase httpContext)
{
string redirectActionName = ((LegacyRoute) RequestContext.RouteData.Route).RedirectActionName;
var route = new Route(redirectActionName, ((LegacyRoute)RequestContext.RouteData.Route).Defaults, new MvcRouteHandler());
// Copy all of the querystring parameters and put them within RouteContext.RouteData.Values
var values = new Dictionary<string, object>();
foreach (var s in RequestContext.RouteData.Values)
{
values.Add(s.Key, s.Value);
}
foreach (var s in httpContext.Request.QueryString.AllKeys)
{
values.Add(s, httpContext.Request.QueryString[s]);
}
var data = route.GetVirtualPath(RequestContext, new RouteValueDictionary(values));
httpContext.Response.Status = "301 Moved Permanently";
httpContext.Response.AppendHeader("Location", "/" + data.VirtualPath + "/");
httpContext.Response.End();
}
}
Затем я просто добавляю устаревшие маршруты в мою карту маршрутов:
routes.Insert(13, new LegacyRoute("search", "search/{query}", new LegacyRouteHandler()));
