在OwinSelfHost專案中，獲取客戶端的IP地址可以透過以下方法獲得：

  • base.Request.GetOwinContext().Request.RemoteIpAddress

建立一個OwinSelfHost專案的大概過程：

  • 建立名稱為OwinSelfHostSample的Windows窗體應用(.NET Framework)專案；
  • 重新命名Form1為MainForm；
  • 在NuGet包管理器中新增中新增Microsoft.AspNet.WebApi.OwinSelfHost；
  • 新增Startup類；
  • 新增控制器類MainController。

各個類的程式碼如下：

  • Program
 1 using System;
 2 using System.Windows.Forms;
 3 
 4 namespace OwinSelfHostSample
 5 {
 6     internal static class Program
 7     {
 8         [STAThread]
 9         static void Main()
10         {
11             Application.EnableVisualStyles();
12             Application.SetCompatibleTextRenderingDefault(false);
13             Application.Run(new MainForm());
14         }
15     }
16 }
  • Startup
 1 using Owin;
 2 using System.Net.Http.Headers;
 3 using System.Web.Http;
 4 
 5 namespace OwinSelfHostSample
 6 {
 7     internal class Startup
 8     {
 9         public void Configuration(IAppBuilder appBuilder)
10         {
11             var config = new HttpConfiguration();
12             config.Routes.MapHttpRoute("DefaultApi", "api/{controller}/{action}/{id}", new { id = RouteParameter.Optional });
13 
14             appBuilder.UseWebApi(config);
15         }
16     }
17 }
  • MainController
 1 using System.Net.Http;
 2 using System.Web.Http;
 3 
 4 namespace OwinSelfHostSample
 5 {
 6     public class MainController : ApiController
 7     {
 8         [HttpGet, HttpPost]
 9         public IHttpActionResult GetClientIp()
10         {
11             var result = base.Request.GetOwinContext().Request.RemoteIpAddress;
12             return Ok(result);
13         }
14     }
15 }
  • MainForm
 1 using Microsoft.Owin.Hosting;
 2 using System;
 3 using System.Windows.Forms;
 4 
 5 namespace OwinSelfHostSample
 6 {
 7     internal partial class MainForm : Form
 8     {
 9         public MainForm()
10         {
11             this.InitializeComponent();
12         }
13 
14         private void button1_Click(object sender, EventArgs e)
15         {
16             WebApp.Start<Startup>("http://127.0.0.1:8090");
17             this.button1.Enabled = false;
18         }
19     }
20 }
