Asp.NetCore 从控制台到WebApi

一、新建一个.NetCore控制台程序

二、添加依赖项

三、添加Startup.cs文件

using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Http;
using System;
using System.Collections.Generic;
using System.Text;
 
namespace ConsoleWeb
{
    public class Startup
    {
 
        public void Configure(IApplicationBuilder app)
        {
            app.Run(context =>
            {
                return context.Response.WriteAsync("Hello world");
            });
        }
    }
}

四、Program.cs文件添加 Microsoft.AspNetCore.Hosting 引用，创建WebHost对象

using Microsoft.AspNetCore.Hosting;
using System;
using System.IO;
 
namespace myFirstConsoleDemo
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Hello World!");
 
            var host = new WebHostBuilder()
            .UseKestrel()
            .UseContentRoot(Directory.GetCurrentDirectory())
            .UseStartup<Startup>()
            .Build();
 
            host.Run();
        }
    }
}

五、运行

浏览器输入localhost；5000

六、加入WebApi

项目根目录下添加一个Api文件夹用来放Api，在Api中新建一个TestApi.cs 继承自ControllerBase

using Microsoft.AspNetCore.Mvc;
using System;
using System.Collections.Generic;
using System.Text;
 
namespace ConsoleWeb.Api
{
    public class TestApi:ControllerBase
    {
        [Route("test/index")]
        public string Index()
        {
            return "hello api";
        }
    }
}

Startup.cs中加入ConfigureServices方法

using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Http;
using Microsoft.Extensions.DependencyInjection;
using System;
using System.Collections.Generic;
using System.Text;
 
namespace ConsoleWeb
{
    public class Startup
    {
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddMvc();
        }
 
        public void Configure(IApplicationBuilder app)
        {
            app.UseMvc(s=> {
                s.MapRoute("default", "{controller}/{action}/{id?}", "test/index");
            });
            app.Run(context =>
            {
                return context.Response.WriteAsync("Hello world");
            });
        }
    }
}

运行程序、在浏览器地址栏中输入localhost:5000/test/index

七、添加页面，搭建webMVC application

编辑    .csproj文件

到HomeController.cs文件中 选中要添加视图的Action

添加成功后会自动引入以下几个NuGet包

现在运行 就可以看到页面了
