MVC3 Route 总结 Kevin

1. 指定Controller、Action

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

匹配：http://www.xxx.com/home/Index.

2.带默认参数指定

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.静态参数和变量混用

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.不带controller

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

匹配：http://www.xxx.com/X/Index.

5.自定义路由变量

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

自定义变量不能使用controller、action和area作为变量名。

6.访问路由变量的值

RouteData.Value[""]的值。

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

另外一种方法就是把自定义变量当作Action的值传入到Action方法里面,如：

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

7.定义选择性URL变量

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

这样，URL里包含和不包含id变量的值都能通过编译。

8.通过C#选择性参数指定变量的默认值

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

9.定义可变长度的路由变量

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. 包含多个相同名称的Controller

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

通过指定controller的命名空间来区别两个名称相同的controller

可以通过指定告诉MVC Framework只在某一命名空间中寻找对应的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.通过正则表达式限制路由

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必须是以H字母开头的

限制路由为特定的值：

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

限制了路由为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.从路由数据中构造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"});//只产生URL，不带Action

13.在Action方法中产生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.重定向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.从特定路由中获取连接

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