Window sevice +OWIN+webapi

webapi正常都托管在iis上，这里引入owin，将其托管在window服务上。

第一步：创建一个服务，这里就不多描述。

第二步：引入OWIN

2.1引入bll

 2.2加入api路由配置

    public class Startup
    {
        public void Configuration(IAppBuilder appBuilder)
        {
            HttpConfiguration config = new HttpConfiguration();

            config.MapHttpAttributeRoutes();

            config.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );

            //添加允许跨域
            var CorsConfig = new EnableCorsAttribute(origins: "*", headers: "*", methods: "*")
            {
                PreflightMaxAge = 1800,
                SupportsCredentials = true
            };
            config.EnableCors(CorsConfig);

            appBuilder.UseWebApi(config);

        }
    }

2.3监听ip和端口

        protected override void OnStart(string[] args)
        {
            _server = WebApp.Start<Startup>(url: "http://192.168.200.84:2000/");
            Console.WriteLine("Service start success...");
        }

第三步：加入webapi接口

namespace WebSocketService.Controllers
{
    public class HomeController : HomeControllerBase
    {
    }
}

基类：

namespace GameCommon.Controllers
{
    public class HomeControllerBase : ApiController
    {
        [HttpGet]
        public object Get()
        {
            return new { Age=12,Name="Holle world"};
        }

        [HttpPost]
        public object Post()
        {
            return new { Age = 12, Name = "Holle world" };
        }
    }
}

我这里将接口单独提取了一个DLL文件来处理。

项目结构：

另外这里再贴上webSocket的代码：

using GameCommon.Controllers;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace WebSocketService.Controllers
{
    public class ConnectController:ConnectControllerBase
    {
    }
}

基类：

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

namespace GameCommon.Controllers
{
    using WebSocketAccept = System.Action<System.Collections.Generic.IDictionary<string, object>,System.Func< 
        System.Collections.Generic.IDictionary<string, object>, System.Threading.Tasks.Task>>;
    public class ConnectControllerBase : ApiController
    {
        [HttpGet]
        public HttpResponseMessage Connect()
        {
            try
            {
                if (Request.Method != HttpMethod.Get)
                {
                    return new HttpResponseMessage(HttpStatusCode.NotFound);
                }

                IOwinContext owinContext = Request.GetOwinContext();
                WebSocketAccept acceptToken = owinContext.Get<WebSocketAccept>("websocket.Accept");
                if (acceptToken != null)
                {
                    acceptToken(null, ProcessSocketConnection);
                }
                else
                {
                    return new HttpResponseMessage(HttpStatusCode.BadRequest);
                }
                return new HttpResponseMessage(HttpStatusCode.SwitchingProtocols);
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
                return null;
            }
        }

        public async Task ProcessSocketConnection(IDictionary<string, object> wsEnv)
        {
            WebSocket wSocket = ((HttpListenerWebSocketContext)wsEnv["System.Net.WebSockets.WebSocketContext"]).WebSocket;

            while (true)
            {
                ArraySegment<byte> buffer = new ArraySegment<byte>(new byte[10240]);
                WebSocketReceiveResult receivedResult;

                receivedResult = await wSocket.ReceiveAsync(buffer, CancellationToken.None);

                if (receivedResult.MessageType == WebSocketMessageType.Close)
                {
                    await wSocket.CloseAsync(WebSocketCloseStatus.Empty, string.Empty, CancellationToken.None);
                    break;
                }

                if (wSocket.State == WebSocketState.Open)
                {
                    string receivedJson = Encoding.UTF8.GetString(buffer.Array, 0, receivedResult.Count);
                }
            }

        }
    }
}
