新建一个self hosted Owin+ SignalR Project(1)

OWIN是Open Web Server Interface for .Net 的首字母缩写,他的定义如下:

OWIN在.NET Web Server 与Web Application之间定义了一套标准接口,OWIN的目标是用于解耦Web Server和Web Application.基于此标准,鼓励开发者开发简单,灵活的模块,从而推进.Net Web Development开源生态系统的发展.之前.net开发的所有webSite和Web Application不得不和IIS绑定到一起部署,对于部署,相当笨重.而OWIN正好是为了解决这个问题!

1.新建一个Console项目

2.添加Owin self host 引用,打开NuGet 程序包管理平台,输入如下代码:

>install-package Microsoft.Aspnet.WebApi.OwinSelfHost

3.新建一个名字为StartUp.cs的类,添加如下代码:

using Owin;

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using System.Web.Http;

namespace TestProgram

{

   public class Startup

    {

        public void Configuration(IAppBuilder app)

        {

            //模仿站点配置

            HttpConfiguration config = new HttpConfiguration();

            //添加站点路由

            config.Routes.MapHttpRoute(

                name: "DefaultApi",

                routeTemplate: "api/{controller}/{action}/{id}", //这里为了类MVC特别加入了{action}

                defaults: new { id = RouteParameter.Optional });

            app.UseWebApi(config);

        }

    }

}

4.添加Controller,新建文件夹Controller,添加IndexController.cs,添加如下代码:

using System;

using System.Collections.Generic;

using System.IO;

using System.Linq;

using System.Net.Http;

using System.Net.Http.Headers;

using System.Text;

using System.Threading.Tasks;

using System.Web.Http;

namespace TestProgram.Controller

{

  public  class IndexController:ApiController

    {

        public string Get(string name)

        {

            return name;

        }

     }

}

5.将Owin站点启动,修改Program.cs,如下:

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 TestProgram

{

    class Program

    {

        static void Main(string[] args)

        {

            //此入口是Owin站点的宿主

            string baseAddress = "http://localhost:9009/";//站点启动地址

            using (WebApp.Start<Startup>(baseAddress))

            {

                HttpClient client = new HttpClient();

                //var response = client.GetAsync(baseAddress + "api/index").Result;

                //Console.WriteLine(response);

                //Console.WriteLine(response.Content.ReadAsStreamAsync().Result);

                Console.ReadLine();//不让宿主程序结束

            }

        }

    }

}

6.运行程序,打开浏览器输入 http://localhost:9009/index/index?name="RemiHoston"

由于没有设置返回的数据类型,所以默认返回XMl格式,但是,只是返回字符串并不能满足要求;但是Owin self hosted 程序宿主于Console没有提供文件下载访问,所以我们要自己提供接口支持文件访问

7.添加静态文件访问的接口

修改IndexController.cs添加如下两个方法:

 [HttpGet]

        public HttpResponseMessage Index()

        {

            //构造文件路径,代码重构的时候可以把这一块代码封装成公用方法

            var currentRunPath = AppDomain.CurrentDomain.BaseDirectory;

            var substringBin = currentRunPath.IndexOf("bin");

            //返回Index.html文件

            var path = currentRunPath.Substring(, substringBin) + "Index.html";

            var httpResponseMessage = new HttpResponseMessage();

            httpResponseMessage.Content = new StringContent(File.ReadAllText(path), Encoding.UTF8);

            httpResponseMessage.Content.Headers.ContentType = new MediaTypeHeaderValue("text/html");

            //把文件内容读出来,以HttpResponseMessage的形式返回客户端

            return httpResponseMessage;

        }

        /// <summary>

        /// 获取静态文件,比如css,javascript

        /// </summary>

        /// <param name="fileName"></param>

        /// <returns></returns>

        [HttpGet]

        public HttpResponseMessage GetResource(string fileName)

        {

            //构造文件路径,代码重构的时候可以把这一块代码封装成公用方法

            var currentRunPath = AppDomain.CurrentDomain.BaseDirectory;

            var substringBin = currentRunPath.IndexOf("bin");

            var path = currentRunPath.Substring(, substringBin) + fileName;

            var httpResponseMessage = new HttpResponseMessage();

            if (!File.Exists(path))

            {

                httpResponseMessage.StatusCode = System.Net.HttpStatusCode.NotFound;

                return httpResponseMessage;

            }

            httpResponseMessage.Content = new StringContent(File.ReadAllText(path), Encoding.UTF8);

            httpResponseMessage.Content.Headers.ContentType = new MediaTypeHeaderValue("text/html");

            return httpResponseMessage;

        }

8.新建站点页面

站点根目录下新建Script文件夹,下载添加query-1.6.4.min.js,新建Index.html,添加如下代码:

<!DOCTYPE html>

<html lang="en" xmlns="http://www.w3.org/1999/xhtml">

<head>

    <meta charset="utf-8" />

    <title>Owin默认页</title>

    <!--通过站点接口,下载Jquery-->

    <script src="getresource?filename=scripts/jquery-1.6.4.min.js"></script>

    <script type="text/javascript">

        $(function () {$('body').append("<h1>Hello Owin!</h1>") })

    </script>

</head>

<body>

</body>

</html>

运行重新刷新,页面

至此,解决了Owin Self Hosted Console 程序加载页面的问题,下一篇将在此基础上新建SignalR程序!
