MVC自定义路由01-为什么需要自定义路由

本篇体验自定义路由以及了解为什么需要自定义路由。

准备

□ View Models

using System.Collections.Generic;

namespace MvcApplication2.Models

    //单位

    public class Unit

        public int ID { get; set; }

        public RentalProperty RentalProperty { get; set; }

        public string Name { get; set; }

    //属性

    public class RentalProperty

        public int ID { get; set; }

        public string Name { get; set; }

    public class RentalPropertyTestData

        public int ID { get; set; }

        public List<RentalProperty> RentalProperties { get; set; }

        public List<Unit>  Units { get; set; }

□ 模拟一个数据层服务类

using MvcApplication2.Models;

using System.Collections.Generic;

namespace MvcApplication2.Service

    public class RentalService

        public  RentalPropertyTestData GetData()

            List<RentalProperty> rps = new List<RentalProperty>();

            RentalProperty rp1 = new RentalProperty() { ID = 1, Name = "长度" };

            RentalProperty rp2 = new RentalProperty() { ID = 2, Name = "重量" };

            rps.Add(rp1);

            rps.Add(rp2);

            List<Unit> units = new List<Unit>();

            Unit unit1 = new Unit() { ID = 1, Name = "米", RentalProperty = rp1 };

            Unit unit2 = new Unit() { ID = 2, Name = "公斤", RentalProperty = rp2 };

            units.Add(unit1);

            units.Add(unit2);

            return new RentalPropertyTestData()

                ID = 1,

                RentalProperties = rps,

                Units = units

};

RentalPropertiesController

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.Mvc;

using Microsoft.Ajax.Utilities;

using MvcApplication2.Models;

using MvcApplication2.Service;

namespace MvcApplication2.Controllers

    public class RentalPropertiesController : Controller

        RentalPropertyTestData _data = new RentalPropertyTestData();

        public RentalPropertiesController()

            RentalService s = new RentalService();

            _data = s.GetData();

        public ActionResult All()

            return View(_data);

        public ActionResult RentalProperty(string rentalPropertyName)

            var rentalProperty = _data.RentalProperties.Where(a => a.Name == rentalPropertyName).FirstOrDefault();

            return View(rentalProperty);

        public ActionResult Unit(string rentalPropertyName, string unitName)

            var unit = _data.Units.Find(u => u.Name == unitName && u.RentalProperty.Name == rentalPropertyName);

            return View(unit);

视图

□ All.csthml

@model MvcApplication2.Models.RentalProperty

@{
    Layout = null;
}

<!DOCTYPE html>

<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>RentalProperty</title>
</head>
<body>
    <div>
        所选择的属性名称：@Model.Name
    </div>
</body>
</html>

□ RentalProperty.cshtml

@model MvcApplication2.Models.RentalProperty

@{
    Layout = null;
}

<!DOCTYPE html>

<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>RentalProperty</title>
</head>
<body>
    <div>
        所选择的属性名称：@Model.Name
    </div>
</body>
</html>

□ Unit.cshtml

@model MvcApplication2.Models.Unit

@{
    Layout = null;
}

<!DOCTYPE html>

<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>Unit</title>
</head>
<body>
    <div>
        所选选择的属性名称：@Model.RentalProperty.Name
        <br/>
        所选择的单位名称：@Model.Name
    </div>
</body>
</html>

效果

All.csthml

RentalProperty.cshtml

Unit.cshtml

路由改进目标

■ http://localhost:1368/RentalProperties/All 改进为 ~/rentalproperties/
■ http://localhost:1368/RentalProperties/RentalProperty?rentalPropertyName=长度改进为 ~/rentalproperties/rentalPropertyName/
■ http://localhost:1368/RentalProperties/Unit?rentalPropertyName=长度&unitName=米改进为 ~/rentalproperties/rentalPropertyNam/units/unitName

添加自定义路由规则

using System.Web.Mvc;
using System.Web.Routing;

namespace MvcApplication2
{
    public class RouteConfig
    {
        public static void RegisterRoutes(RouteCollection routes)
        {
            routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
            //对应~/rentalproperties/rentalPropertyNam/units/unitName
            routes.MapRoute(
                name:"RentalPropertyUnit",
                url: "RentalProperties/{rentalPropertyName}/Units/{unitName}",
                defaults:new
                {
                    controller = "RentalProperties",
                    action = "Unit"
                }
            );

            //对应~/rentalproperties/rentalPropertyName/
            routes.MapRoute(
                name: "RentalProperty",
                url: "RentalProperties/{rentalPropertyName}",
                defaults: new
                {
                    controller = "RentalProperties",
                    action = "RentalProperty"
                }
            );

            //对应~/rentalproperties/
            routes.MapRoute(
                name: "Rental",
                url: "RentalProperties",
                defaults: new
                {
                    controller = "RentalProperties",
                    action = "All"
                }
            );

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

□ 效果

http://localhost:1368/RentalProperties

http://localhost:1368/RentalProperties/长度

http://localhost:1368/RentalProperties/长度/Units/米
