（初识MVC Core）四、设置MVC

1.注册MVC服务到Ioc容器（services.AddMvc();）

2.在ASP.NET Core管道里使用并配置MVC中间件

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using CoreModelTwo.Services;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Http;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;

namespace CoreModelTwo
{
    public class Startup
    {
        // This method gets called by the runtime. Use this method to add services to the container.
        // For more information on how to configure your application, visit https://go.microsoft.com/fwlink/?LinkID=398940
        public void ConfigureServices(IServiceCollection services)
        {
            //注册MVC所需要的相关服务到IoC容器里
            services.AddMvc();

            //使用Singleton进行IoC依赖注入（每当有请求IMovieService都会返回MovieService实例）
            services.AddSingleton<IMovieService,MovieService>();
            services.AddSingleton<ICinemaService, CinemaService>();
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IHostingEnvironment env,ILogger<Startup> logger)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }

            #region 配置路由

            //将错误显示在页面
            app.UseStatusCodePages();
            //跳转到指定错误位置
            //app.UseStatusCodePagesWithRedirects("/Error");         

            //加载wwwroot里头的文件（使用此可以加载出来）
            app.UseStaticFiles();

            //配置路由
            app.UseMvc(routes=> {
                routes.MapRoute(
                    name:"default",
                    template:"{controller=Home}/{action=Index}/{id?}");
            });

            #endregion

        }
    }
}
