asp.net-mvc - MVC Routing中的ACTION参数可以重命名吗？

Question

我的 RouteConfig,cs 文件中有以下路由：

routes.MapRoute(
    name: "SectionHomePage",
    url: "{SectionType}/{SectionID}",
    constraints: new { SectionType = @"(Books|Cinema|Collections|Games)" },
    defaults: new { controller = "SectionHomePageController" }
    );

如果可能的话，我想做的是将action参数重命名为SectionType或以某种方式分配SectionType给action参数。（我知道我可以重命名SectionType为，action但为了便于阅读，我想保持命名）。

控制器：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace FFInfo.WebUI.Controllers
{
    public class SectionHomePageController : Controller
    {
        // GET: /SectionHomePage/
        public ActionResult Games()
        {
            //ViewBag.Head = RouteData.Values["id"];
            return View();
        }
    }
}

错误：

RouteData 必须包含一个名为 'action' 且具有非空字符串值的项目。

Answer 1

需要操作，但是您可以在路线中设置操作

routes.MapRoute(
    name: "SectionHomePage",
    url: "{SectionType}/{SectionID}",
    constraints: new { SectionType = @"(Books|Cinema|Collections|Games)" },
    defaults: new { controller = "SectionHomePageController", action="Section" }
);

这假设您有一个 SectionHomePageController ，其操作类似于此

public ActionResult Section(string sectionType, int sectionId) 
{
    // can use a switch...case instead
    if (sectionType == "Books")
       return Books(sectionId);
}
public ActionResult Books(int sectionId)
{
    var model = GetBooksModel(); // load stuff
    return View("Books", model); // Set view and provide model
}

或者，您可以

routes.MapRoute(
    name: "SectionHomePage",
    url: "{action}/{SectionID}",
    constraints: new { action = @"(Books|Cinema|Collections|Games)" },
    defaults: new { controller = "SectionHomePageController" }
);

与 actionResult 的

public ActionResult Books(int sectionId) 
{
    var model = GetBooksModel(); // load stuff
    return View("Books", model); // Set view and provide model
}

public ActionResult Cinema(int sectionId) 
{
    ...
}

无法重命名 ACTION 元素。
