基于空项目模板创建使用Owin来host的WebApi项目
首先创建一个空的web项目，如下图所示：
项目创建成功以后，安装下面三个package.
Install-Package Microsoft.AspNet.WebApi -Version 5.2.2
Install-Package Microsoft.AspNet.WebApi.Owin -Version 5.2.2
Install-Package Microsoft.Owin.Host.SystemWeb -Version 3.0.0
创建Owin Startup 类
1 using System; 2 using System.Threading.Tasks; 3 using Microsoft.Owin; 4 using Owin; 5 using System.Web.Http; 6 7 [assembly: OwinStartup(typeof(FirstOwinWebApi.Startup))] 8 9 namespace FirstOwinWebApi 10 { 11 public class Startup 12 { 13 public void Configuration(IAppBuilder app) 14 { 15 HttpConfiguration config = new HttpConfiguration(); 16 17 // Web API routes 18 config.MapHttpAttributeRoutes(); 19 20 //WebApiConfig.Register(config); 21 22 app.UseWebApi(config); 23 } 24 } 25 }
创建API Controller.
1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Net; 5 using System.Net.Http; 6 using System.Web.Http; 7 8 namespace FirstOwinWebApi.Controllers 9 { 10 [RoutePrefix("api/HelloWorld")] 11 public class HelloWorldController : ApiController 12 { 13 [Route("")] 14 public IHttpActionResult Post() 15 { 16 17 return Ok<string>("Hello World"); 18 19 } 20 21 } 22 }
F5运行，使用Postman访问Api
其他一些Owin中间件包：
Install-Package Microsoft.AspNet.WebApi -Version 5.2.2
Install-Package Microsoft.AspNet.WebApi.Owin -Version 5.2.2
Install-Package Microsoft.Owin.Host.SystemWeb -Version 3.0.0
Install-Package Microsoft.Owin.Cors -Version 3.0.0
Install-Package Microsoft.Owin.Security.OAuth -Version 3.0.0
Install-Package Microsoft.Owin.Security.Jwt -Version 3.0.0
Install-Package System.IdentityModel.Tokens.Jwt -Version 4.0.0
Install-Package Thinktecture.IdentityModel.Core Version 1.2.0
Install-Package Microsoft.AspNet.Identity.Owin -Version 2.0.1
Install-Package Microsoft.AspNet.Identity.EntityFramework -Version 2.0.1
