C# Owin快速搭建网站(免IIS),一个.exe文件即是一个服务器

界面： 

 

结构：

一、新建winform工程

NuGet安装以下几个包:

(1):Microsoft.AspNet.WebApi.OwinSelfHost

 

(2):Microsoft.AspNet.SignalR

(3)静态文件处理的中间件:Beginor.Owin.StaticFile

(4)Microsoft.Owin.Cors

 

(5) 将其他dll打包成一个exe:Costura.Fody

 

 二、代码

启动类：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using System.Windows.Forms;
using OwinTest2.model;
using OwinTest2.view;

namespace OwinTest2
{
    static class Program
    {
        /// 

        /// 应用程序的主入口点。
        /// 
        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Application.Run(GlobalData.GetForm1());
        }
    }
}

 

Form1 类：

using System;
using System.Net;
using System.Threading;
using System.Windows.Forms;
using Microsoft.Owin.Hosting;
using OwinTest2.server;
using OwinTest2.model;

namespace OwinTest2.view
{
    public partial class Form1 : Form
    {
        //Owin服务实例对象
        private IDisposable disposeable;

        public Form1()
        {
            InitializeComponent();
            Init();
        }

        private void Init()
        {
            //非主线程亦可操作界面
            CheckForIllegalCrossThreadCalls = false;
            log_textBox.Text = "日志:\r\n";
            SetLog("开始获取本机IP...");
            //获取本机IP
            IPHostEntry here = Dns.GetHostEntry(Dns.GetHostName());
            foreach (IPAddress _ip in here.AddressList)
            {
                if (_ip.AddressFamily.ToString().ToUpper() == "INTERNETWORK")
                {
                    GlobalData.ServerIp = _ip.ToString();
                    //GlobalData.Port = (9000 + new Random().Next(1000)).ToString();
                    new Thread(() =>
                    {
                        //本地Http服务器
                        string baseAddress = "http://" + GlobalData.ServerIp + ":" + GlobalData.Port;
                        disposeable = WebApp.Start(url: baseAddress);
                    })
                    { Name = "获取日志线程" }.Start();
                    break;
                }
            }
            this.Text = this.Text + "  " + GlobalData.ServerIp + ":" + GlobalData.Port;
            SetLog("本机IP端口:" + GlobalData.ServerIp + ":" + GlobalData.Port);
        }

        public void SetLog(string log)
        {
            log_textBox.AppendText(log + "\r\n");
        }

        private void Form1_FormClosing(object sender, FormClosingEventArgs e)
        {
            DialogResult result = MessageBox.Show("确认退出吗?", "提示", MessageBoxButtons.OKCancel, MessageBoxIcon.Information);
            if (result == DialogResult.OK)
            {
                disposeable.Dispose();
                //Dispose();
                //Application.Exit();
                System.Environment.Exit(0);
            }
            else
            {
                e.Cancel = true;
            }
        }
    }
}

LoginController 控制类(可用来处理异步请求)：

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Net.Http.Headers;
using System.Text;
using System.Threading.Tasks;
using System.Web;
using System.Web.Http;

namespace OwinTest2.controllers

    public class LoginController:ApiController

        [HttpPost]
        public HttpResponseMessage login([FromBody]Obj obj)
        {
            StringBuilder msg = new StringBuilder();
            if (obj == null)
            {
                msg.Append("参数不能为空");
            }
            else

            //设置Cookie
            var cookie = new CookieHeaderValue("u_id", obj.u_id);
            cookie.Expires = DateTimeOffset.Now.AddDays(1);
            cookie.Domain = Request.RequestUri.Host;
            cookie.Path = "/";
            httpResponseMessage.Headers.AddCookies(new CookieHeaderValue[] { cookie });
            //返回index.html页面
            httpResponseMessage.Content = new StringContent(File.ReadAllText(@".\page\index.html"), Encoding.UTF8);
            //指定返回什么类型的数据
            httpResponseMessage.Content.Headers.ContentType = new MediaTypeHeaderValue("text/html");
            
            return httpResponseMessage;
        }

        public class Obj
        {
            public string u_id { get; set; }
            public string u_pwd { get; set; }
        }
    }
}
