ASP.Net WebForms 路由多个目的地的单一路由 [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.我一直在查看以下有关使用数据库中的friendlyUrls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，我想为多个实体使用相同的路由结构.含义:

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

mysite.com/{PlayerName} 转到 player.aspxmysite.com/{TeamName} 转到 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 实现这一目标的正确方向吗?是否可以使用内置的路由引擎，或者我应该为此编写自己的 HTTPModule 代码?

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?

谢谢大卫

推荐答案

写两个constraints 返回布尔值是否段是一个团队/一个球员与否.

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，注册页面路由将使用约束来检查路由是否有效，如果有效则执行页面.

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.

我还没有在 ASP.Net Forms 中尝试过这个，但我的应用程序在 ASP.Net MVC 中开发的约束条件下运行.两种类型的应用程序(Forms 和 MVC)共享公共路由逻辑.

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.
