如何根据参数在MVC中为不同的控制器设置路由 [英] How do I set up routing in MVC for different controllers based on parameters

问题描述

在ASP.Net MVC5中需要帮助才能知道这是否可行



我想设置路由，以便



1。 www.myWebsite.com 指向主页/索引和

2。 www.myWebsite.com/2/3 指向章节/索引



我有一个带无参数索引动作的HomeController （使用默认路由配置工作正常）和

我有一个带有2个参数的ChapterController，其值必须从URL输入（例如：上面示例URL中的2& 3） />


我目前的路由如下

Hi,

Need help to know if this is possible in ASP.Net MVC5

I want to set up routing such that

1. www.myWebsite.com points to Home/Index and
2. www.myWebsite.com/2/3 points to Chapter/Index

I have a HomeController with a parameterless Index action (which works fine with the default route config) and
I have a ChapterController with 2 parameters whose values must be fed in from the URL (e.g.: 2 & 3 from the sample URL above)

My current routing is as below

routes.MapRoute(
                name: "Default",
                url: "{controller}/{action}/{id}",
                defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
            );

我的章节控制器如下

My chapter controller is as below

public class ChapterController : Controller
{
        public ActionResult Index(short? chapterID, short? verseNumber)
        {

            ViewModel vm = new ViewModel();
            vm.message = $"chapter: {chapterID} & verse: {verseNumber}";
            return View(vm);
        }
}

我的尝试：



试图添加一个MapRoute条目如下，但它不起作用:(

What I have tried:

tried to add a MapRoute entry as below but it doesnt work :(

routes.MapRoute(
    name: "Chapter",
    url: "{chapterID}/{verseNumber}",
    defaults: new { controller = "Chapter", action = "Index", verseNumber = UrlParameter.Optional }
);

推荐答案

章节：{chapterID}& verse：{verseNumber};
返回查看（vm）;
}
}

"chapter: {chapterID} & verse: {verseNumber}"; return View(vm); } }

尝试为参数添加约束：

Try adding constraints to your parameters:

routes.MapRoute(
    name: "Chapter",
    url: "{chapterID}/{verseNumber}",
    defaults: new { controller = "Chapter", action = "Index", verseNumber = UrlParameter.Optional },
    constraints: new { chapterID = @"\d+", verseNumber = @"\d*" }
);

确保它出现在默认路线之前。

Make sure this appears before the default route.
