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();
}
}
