ASP.Net WebForms路由多个目标的单个路由 [英] ASP.Net WebForms Routing Single Route for Multiple Destinations

问题描述

我正在考虑为我计划创建的新网站设置数据库路由。我一直在关注以下有关利用数据库中的friendlyUrl的教程：

I am looking into setting database routing up for a new website I plan to create. I have been looking at the following tutorial with regards to utilising friendlyUrls from a database:

http://www.asp.net/web-forms/tutorials/aspnet-45 / getting-started-with-aspnet-45-web-forms / url-routing

但是，我想将相同的路由结构用于多个实体。含义：

However, I would like to use the same route structure for multiple entities. Meaning:

mysite.com/ {PlayerName}进入player.aspx
mysite.com/{TeamName}进入team.aspx
……等等……

mysite.com/{PlayerName} goes to player.aspx mysite.com/{TeamName} goes to team.aspx … and so on …

有人可以指出使用asp.net实现此目标的正确方向。可以使用内置的路由引擎，还是应该为此编写自己的HTTPModule？

Could somebody point in the right direction of achieving this with asp.net. Is it possible using the built in routing engine, or should I be looking to code my own HTTPModule for this?

推荐答案

写两个约束，它会返回布尔值，无论该段是否是团队/是否是球员/是否是球员。

Write two constraints which return boolean whether segment is a team or not / a player or not.

public class IsTeamConstraint : IRouteConstraint
{
    public bool Match
        (
            HttpContextBase httpContext, 
            Route route, 
            string parameterName, 
            RouteValueDictionary values, 
            RouteDirection routeDirection
        )
    {
        return SomeService.IsTeam(values["teamName"]);
    }
}

public class IsPlayerConstraint : IRouteConstraint
{
    public bool Match
        (
            HttpContextBase httpContext, 
            Route route, 
            string parameterName, 
            RouteValueDictionary values, 
            RouteDirection routeDirection
        )
    {
        return SomeService.IsPlayer(values["playerName"]);
    }
}

在页面路由中设置约束。

Set constraint in page route.

void RegisterCustomRoutes(RouteCollection routes)
{
    routes.MapPageRoute(
        "Team",
        "{teamName}",
        "~/Team.aspx",
        false,
        null,
        new RouteValueDictionary { { "isTeam", new IsTeamConstraint() } }
    );
    routes.MapPageRoute(
        "Player",
        "{playerName}",
        "~/Player.aspx",
        false,
        null,
        new RouteValueDictionary { { "isPlayer", new IsPlayerConstraint() } }
    );
}

现在，当请求页面时，已注册的页面路由将使用约束条件来检查

Now when a page is requested registered page routes will use constraint to check that the route is valid and execute page if it is.

我没有在ASP.Net Forms中尝试过此操作，但是我运行的应用程序在ASP.Net MVC中开发了约束。两种类型的应用程序（窗体和MVC）都共享通用的路由逻辑。

I haven't tried this in ASP.Net Forms but I've applications running with constraints developed in ASP.Net MVC. Both type of application (Forms and MVC) shared common routing logic.
