如何在路径中检索站点范围的URL参数,而不会使用参数混乱每个控制器操作？我的问题类似于
this question,但我想避免使用ModelBinder的混乱. IE浏览器.在Global.asax.cs中：
- routes.MapRoute(
- "Default",// Route name
- "{sitename}/{controller}/{action}/{id}",new { sitename = "",controller = "SomeController",action = "Index",id = "" } );
所以,而不是SomeController类中的以下内容：
- public ActionResult Index(string sitename)
- {
- SiteClass site = GetSite(sitename);
- ...
- return View(site.Getviewmodel());
- }
我宁愿拥有以下内容：
- public ActionResult Index()
- {
- SiteClass site = CurrentSite; // where CurrentSite has already retrieved data based on unique URL sitename parameter.
- ...
- return View(site.Getviewmodel());
- }
也许这可以通过控制器范围的动作过滤器来实现？ OnActionExecuting？
解决方法
首先添加一个到Global.aspx.cs的路由来传递{sitename}参数：
- routes.MapRoute(
- "Sites",// URL with parameters
- new { sitename = "",controller = "Home",id = "" } // Parameter defaults
- );
- public class BaseController: Controller
- {
- public string SiteName = "";
- protected override void OnActionExecuting(ActionExecutingContext filterContext)
- {
- HttpRequestBase req = filterContext.HttpContext.Request;
- SiteName = filterContext.RouteData.Values["sitename"] as string;
- base.OnActionExecuting(filterContext);
- }
- }
并在派生控制器中使用：
- public class HomeController: BaseController
- {
- public ActionResult Index()
- {
- ViewData["SiteName"] = SiteName;
- return View();
- }
- }
