Asp.net MVC學習日記五（自訂RouteHandler）

1、Global.asax中添加

routes.MapRoute("DbContent", "{*path}",new { controller = "Home" }).RouteHandler = new CatalogRouteHandler();

2、在Controller檔案夾下，添加CatalogRouteHandler類，讓其繼承自IRouteHandler

public class CatalogRouteHandler : IRouteHandler
    {
        public IHttpHandler GetHttpHandler(RequestContext requestContext)
        {
            string path = requestContext.RouteData.Values["path"] as string;

            if (path == null)
            {
                requestContext.RouteData.Values["action"] = "Index";
                //add the path minus the command back in
                //requestContext.RouteData.Values["path"] = path;
            }
            else
            {

                //remove trailing slash if there is one
                if (path.EndsWith("/"))
                    path = path.Substring(0, path.Length - 1);
                if (path != null && path.Contains("/")) //valid path parameter
                {
                    int lastIndex = path.LastIndexOf('/');
                    if (lastIndex >= 0)
                    {
                        string commandName = path.Substring(lastIndex + 1);

                        switch (commandName.ToUpper())
                        {
                            case "GET": //get the catalog item
                                requestContext.RouteData.Values["action"] = "Get";
                                //add the path minus the command back in
                                requestContext.RouteData.Values["path"] = path.Substring(0, lastIndex);
                                break;
                            case "DELETE": //delete catalog item
                                requestContext.RouteData.Values["action"] = "Delete";
                                //add the path minus the command back in
                                requestContext.RouteData.Values["path"] = path.Substring(0, lastIndex);
                                break;
                            case "EDIT": //edit catalog item
                                requestContext.RouteData.Values["action"] = "Edit";
                                //add the path minus the command back in
                                requestContext.RouteData.Values["path"] = path.Substring(0, lastIndex);
                                break;
                            case "POST": //save catalog item (insert/update)
                                requestContext.RouteData.Values["action"] = "Post";
                                //add the path minus the command back in
                                requestContext.RouteData.Values["path"] = path.Substring(0, lastIndex);
                                break;
                            default: //we will allow nothing to act as a GET
                                requestContext.RouteData.Values["action"] = "Get";
                                //add the path minus the command back in
                                requestContext.RouteData.Values["path"] = path;
                                break;
                        }

                    }
                }
            }

            return new MvcHandler(requestContext);
        }
    }

 

3、在HomeHandler.cs分別添加Get，Delete，Edit，Post的Action。並添加其對應視圖

        public ActionResult Get(string path)
        {
            return View();
        }
        public ActionResult Delete(string path)
        {
            return View();
        }
        public ActionResult Post(string path)
        {
            return View();
        }
        public ActionResult Edit(string path)
        {
            return View();
        }

訪問的時候加上Home，如http://loaclhost:1124/Home/Edit

ok.
