在webapi2中使用OWIN 自寄宿模式

OWIN  自寄宿模式说的直白一点就是不需要IIS了，直接通过路由访问cs模式的服务

敲了一遍官方的例子，首先安装Microsoft.AspNet.WebApi.OwinSelfHost，注意不要安装错了

建一个控制台的解决方案OwinSelfhostSample，目录结构如下图所示：

创建启动类Startup

代码如下所示：

using System;
using System.Threading.Tasks;
using Microsoft.Owin;
using Owin;
using System.Web.Http;

[assembly: OwinStartup(typeof(OwinSelfhostSample.Startup))]

namespace OwinSelfhostSample
{
    public class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            // 有关如何配置应用程序的详细信息，请访问 http://go.microsoft.com/fwlink/?LinkID=316888
            HttpConfiguration config = new HttpConfiguration();
            config.Routes.MapHttpRoute(name: "DefaultApi",
                routeTemplate: "api/{Controller}/{id}",
                defaults: new
            {
                id = RouteParameter.Optional
            });

            app.UseWebApi(config);
        }
    }
}

新建一个ApiController 类

using System;
using System.Threading.Tasks;
using Microsoft.Owin;
using Owin;
using System.Web.Http;
using System.Collections.Generic;

namespace OwinSelfhostSample
{
    public class ValuesController : ApiController
    {
        public IEnumerable<string> Get()
        {
            return new string[] { "value1", "value2" };
        }

        public string Get(int id)
        {
            return "value";
        }

        public void Post([FromBody]string value)
        {

        }

        public void Put(int id, [FromBody]string value)
        {

        }

        public void Delete(int id)
        {

        }
    }
}

Program 类的中的main方法

using Microsoft.Owin.Hosting;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.Http;
using System.Text;
using System.Threading.Tasks;

namespace OwinSelfhostSample
{
    class Program
    {
        static void Main(string[] args)
        {
            string baseAddress = "http://localhost:9000/";
            using (WebApp.Start<Startup>(url: baseAddress))
            {
                HttpClient client = new HttpClient();
                var response = client.GetAsync(baseAddress + "api/values").Result;
                Console.WriteLine(response);
                Console.WriteLine(response.Content.ReadAsStringAsync().Result);
            }
        }
    }
}
