在項目中經常會用到各種通訊方式，現介紹一下WinForm實現WebApi接口服務，不依賴IIS宿主；編碼道路雖然枯燥，只要我們堅定信念；時光會看見你的成長，也終將不負你的努力。↖(^ω^)↗
NuGet安裝Microsoft.AspNet.WebApi.OwinSelfHost
請求路由Startup.cs
using Owin;using System;using System.Net.Http.Headers;using System.Web.Http;
namespace FilterDemo{ class Startup { public void Configuration(IAppBuilder appBuilder) { try { HttpConfiguration config = new HttpConfiguration(); config.Routes.MapHttpRoute( name: "DefaultApi", routeTemplate: "api/{controller}/{id}", defaults: new { id = RouteParameter.Optional } ); appBuilder.UseWebApi(config); } catch (Exception ex) { throw ex; } } }}
接口方法HomeController.cs
using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;using System.Web.Http;
namespace FilterDemo{ public class HomeController : ApiController { [HttpGet] public IHttpActionResult Get(int address) { string str = "123466"; return Json(str); } [HttpPost] public IHttpActionResult Post([FromBody] List<string> values) { Dictionary<string, object> dic = new Dictionary<string, object>(); try { FormMain.TriggerEvent.Message = values; FormMain.TriggerEvent.OnMessage();
dic.Add("flag", true); dic.Add("msg", "成功"); } catch(Exception ex) { dic.Add("flag", false); dic.Add("msg", ex.Message); } return Json(dic); } [HttpPut] public IHttpActionResult Put(int id, string value) { string str = "123466"; return Json(str); } [HttpDelete] public IHttpActionResult Delete(int id) { string str = "123466"; return Json(str); } }}
啟動WebApi接口服務
#region WebApi接口服務public static OWINTriggerEvent TriggerEvent { get; set; }private IDisposable _webApp;private string BaseUrl = "http://192.168.200.84:2000";
private void StartServer(){string serverIp = ConfigurationManager.AppSettings["ServerIP"];string serverPort = ConfigurationManager.AppSettings["ServerPort"]; BaseUrl = $"http://{serverIp}:{serverPort}";
_webApp = WebApp.Start<Startup>(BaseUrl); AppendLog($"服務已啟動: {BaseUrl}");
var triggerEvent = new OWINTriggerEvent(); TriggerEvent = triggerEvent; TriggerEvent.infoEvent += TriggerEvent_infoEvent;}
private void TriggerEvent_infoEvent(object sender, EventArgs e){try { List<string> msgList = TriggerEvent.Message; AppendLog("接收到信息："+ JsonConvert.SerializeObject(msgList));foreach (var item in msgList) { loadPcdToImage(item); AppendLog("處理點云文件：" + item); } }catch (Exception ex) {throw; }}
private void StopServer(){ _webApp?.Dispose(); AppendLog("服務已停止");}
private void AppendLog(string message){ DateTime d = DateTime.Now;string dateStr = d.ToString("yyyy-MM-dd HH:mm:ss:fff");
if (rtbLog.InvokeRequired) rtbLog.BeginInvoke(new Action(() => rtbLog.AppendText(dateStr + " " + message + "\r\n")));else rtbLog.AppendText(dateStr + " " + message + "\r\n");}#endregion
Microsoft.AspNet.WebApi.OwinSelfHost是一個用于在非IIS環境下自托管ASP.NET Web API的NuGet包，它基于OWIN(Open Web Interface for .NET)規范實現?。
以下是其主要特點和用法：
- 允許Web API脫離IIS運行，可在控制臺應用、Windows服務等環境中托管?
- 使用HttpListener作為底層HTTP服務器?
- 支持完整的Web API功能，包括路由、控制器、過濾器等?
- ?安裝方式?
通過NuGet包管理器控制臺執行命令：
Install-Package Microsoft.AspNet.WebApi.OwinSelfHost
這會自動安裝相關依賴包，包括Microsoft.Owin.Host.HttpListener和Microsoft.AspNet.WebApi.Owin?。
- 創建控制臺應用程序項目(.NET Framework 4.0+) ?
- 比HttpSelfHost更靈活(支持中間件管道)
