MVC3 Route 總結

1. 指定Controller、Action

Routes.MapRoute("","{controller}/{action}");

匹配：http://www.xxx.com/home/Index.

2.帶預設參數指定

Routes.MapRoute("","{controller}/{action}",new {controller="Home",action="Index"});

匹配：http://www.xxx.com/home/Index.

http://www.xxx.com/home/

http://www.xxx.com/

3.靜態參數和變數混用

Routes.MapRoute("","X{controller}/{action}");

匹配:http://www.xxx.com/Xhome/Index;

Routes.MapRoute("","X/{controller}/{action}");

匹配：http://www.xxx.com/X/home/Index.

4.不帶controller

Routes.MapRoute("","X/{action}",new{controller="Home"});

匹配：http://www.xxx.com/X/Index.

5.自訂路由變數

Routes.MapRoute("","{controller}/{action}/{id}",new {controller="Home",action="Index",id="defaultId"});

自訂變數不能使用controller、action和area作為變數名。

6.訪問路由變數的值

RouteData.Value[""]的值。

例如：ViewBag.V=RouteData.Value["action"];

另外一種方法就是把自訂變數當作Action的值傳入到Action方法裡面,如：

public ViewResult CustomVariable(string id) {
ViewBag.CustomVariable = index;
return View();
}

7.定義選擇性URL變數

routes.MapRoute("MyRoute", "{controller}/{action}/{id}",
new { controller = "Home", action = "Index", id = UrlParameter.Optional });
}

這樣，URL裡包含和不包含id變數的值都能通過編譯。

8.通過C#選擇性參數指定變數的預設值

public ViewResult CustomVariable(string id = "DefaultId") {
ViewBag.CustomVariable = id;
return View();
}

9.定義可變長度的路由變數

public static void RegisterRoutes(RouteCollection routes) {
routes.MapRoute("MyRoute", "{controller}/{action}/{id}/{*catchall}",
new { controller = "Home", action = "Index", id = UrlParameter.Optional });
}

 

匹配：mydomain.com/Customer/List/All/Delete //catcall=Delete

mydomain.com/Customer/List/All/Delete/Perm //catcall=Delete/Perm

10. 包含多個相同名稱的Controller

routes.MapRoute("MyRoute", "{controller}/{action}/{id}/{*catchall}",
new { controller = "Home", action = "Index", id = UrlParameter.Optional },
new[] { "URLsAndRoutes.Controllers"});

 

通過指定controller的命名空間來區別兩個名稱相同的controller

可以通過指定告訴MVC Framework只在某一命名空間中尋找對應的Controller

Route myRoute = routes.MapRoute("AddContollerRoute", "Home/{action}/{id}/{*catchall}",
new { controller = "Home", action = "Index", id = UrlParameter.Optional },
new[] { "AdditionalControllers" });
myRoute.DataTokens["UseNamespaceFallback"] = false;
}

 

11.通過Regex限制路由

例如：

routes.MapRoute("MyRoute", "{controller}/{action}/{id}/{*catchall}",
new { controller = "Home", action = "Index", id = UrlParameter.Optional },
new { controller = "^H.*"},
new[] { "URLsAndRoutes.Controllers"});

就限制了controller必須是以H字母開頭的

 

限制路由為特定的值：

routes.MapRoute("MyRoute", "{controller}/{action}/{id}/{*catchall}",
new { controller = "Home", action = "Index", id = UrlParameter.Optional },
new { controller = "^H.*", action = "^Index$|^About$"},
new[] { "URLsAndRoutes.Controllers"});

限制了路由為Index或About方法

 

限制路由的Http方法：

routes.MapRoute("MyRoute", "{controller}/{action}/{id}/{*catchall}",
new { controller = "Home", action = "Index", id = UrlParameter.Optional },
new { controller = "^H.*", action = "Index|About",
httpMethod = new HttpMethodConstraint("GET") },
new[] { "URLsAndRoutes.Controllers" });

12.從路由資料中構造URL

@Html.RouteLink("Routed Link",new{controller="Home",action="About",id="MyID"}); //效果同Action

@Url.RouteUrl(new{controller="Home",action="About",id="MyID"});//只產生URL，不帶Action

13.在Action方法中產生URL

public ViewResult MyActionMethod() {
string myActionUrl = Url.Action("Index", new { id = "MyID" });
string myRouteUrl = Url.RouteUrl(new { controller = "Home", action = "Index" });
... do something with URLs...
}

 

14.重新導向ActionResult

方法一：

public ActionResult MyActionMethod() {
return RedirectToAction("Index");
}

方法二：

public ActionResult MyOtherActionMethod() {
return RedirectToRoute(new { controller = "Home", action = "Index", id = "MyID" });
}

15.從特定路由中擷取串連

routes.MapRoute("MyRoute", "{controller}/{action}");
routes.MapRoute("MyOtherRoute", "App/{action}", new { controller = "Home" });
