OWIN 自託管靜態網站

咱們知道，藉助OWIN，WebApi,SignalR,WCF 均可以建立自託管（Self-Host）實例，徹底不須要IIS，靜態網站也能夠。javascript

最近作一個服務器監控小工具，用 SignalR 通訊，監控端是一個靜態網站（掛在IIS），服務端是一個 WinForm 程序（SignalR 服務寄宿），可是我想網站也寄宿到這個 WinForm 中，這樣經過 WebApp.Start 開啓主機時，網站也開啓了，部署也方便css

爲了減小配置代碼，咱們用一個靜態文件處理的中間件 Beginor.Owin.StaticFilehtml

Install-Package Beginor.Owin.StaticFile

在 OWIN 啓動類中配置java

using Beginor.Owin.StaticFile;

[assembly: OwinStartup(typeof(AisinGioro.Server.OwinStartup))]
namespace AisinGioro.Server
{
    public class OwinStartup
    {
        public void Configuration(IAppBuilder app)
        {
            //靜態文件託管
            app.Map("/wwwroot", map =>
            {
                // 容許跨域
                map.UseCors(CorsOptions.AllowAll);
                map.UseStaticFile(new StaticFileMiddlewareOptions
                {
                    RootDirectory = @"D:\P22\Felix\AisinGioro\AisinGioro.WebPortal",
                    DefaultFile = "index.html",
                    EnableETag = true,
                    EnableHtml5LocationMode = true,
                    MimeTypeProvider = new MimeTypeProvider(new Dictionary<string, string>
                    {
                        { ".html", "text/html" },
                        { ".htm", "text/html" },
                        { ".dtd", "text/xml" },
                        { ".xml", "text/xml" },
                        { ".ico", "image/x-icon" },
                        { ".css", "text/css" },
                        { ".js", "application/javascript" },
                        { ".json", "application/json" },
                        { ".jpg", "image/jpeg" },
                        { ".png", "image/png" },
                        { ".gif", "image/gif" },
                        { ".config", "text/xml" },
                        { ".woff2", "application/font-woff2"},
                        { ".eot", "application/vnd.ms-fontobject" },
                        { ".svg", "image/svg+xml" },
                        { ".woff", "font/x-woff" },
                        { ".txt", "text/plain" },
                        { ".map", "text/plain" }
                    })
                });
            });

            //SignalR託管
            app.Map("/signalr", map =>
            {
                // 容許跨域
                map.UseCors(CorsOptions.AllowAll);

                var hubConfiguration = new HubConfiguration
                {
                    //Resolver = **,
                    // You can enable JSONP by uncommenting line below.
                    // JSONP requests are insecure but some older browsers (and some
                    // versions of IE) require JSONP to work cross domain
                    EnableJSONP = true,
                    EnableDetailedErrors = true
                };                

                // Run the SignalR pipeline. We're not using MapSignalR
                // since this branch is already runs under the "/signalr"
                // path.
                map.RunSignalR(hubConfiguration);
            });

            //該值表示鏈接在超時以前保持打開狀態的時間長度。
            //默認爲110秒
            //GlobalHost.Configuration.ConnectionTimeout = TimeSpan.FromSeconds(110);

            //該值表示在鏈接中止以後引起斷開鏈接事件以前要等待的時間長度。
            //默認爲30秒
            GlobalHost.Configuration.DisconnectTimeout = TimeSpan.FromSeconds(60);
        }
    }
}

其中 RootDirectory 也能夠配置相對目錄，好比 ../app/wwwrootjson

MimeTypeProvider 屬性設置 MIME 映射（Content-Type），若是不設置，Beginor.Owin.StaticFile 只能能判斷普通的類型（好比 html,css,js），因此仍是設置下比較好跨域

建立Web服務監聽，開啓主機服務器

private void DoWork()
        {
            try
            {
                //建立WEB服務器監聽
                using (WebApp.Start<OwinStartup>(_hostUrl))
                {
                    if (this.OnStartSucceed != null)
                        this.OnStartSucceed(this, EventArgs.Empty);

                    LogHelper.Trace("Server started! {0}", _hostUrl);

                    while (!cancelTokenSource.IsCancellationRequested)
                        Thread.Sleep(10);
                }

                LogHelper.Trace("Server stopped!");

                if (this.OnStopSucceed != null)
                    this.OnStopSucceed(this, EventArgs.Empty);  //Server stopped!
            }
            catch (Exception ex)
            {
                ex = ex.GetBaseException();
                LogHelper.Error(ex.Message + " " + _hostUrl);

                if (this.OnFailed != null)
                    this.OnFailed(this, new ErrorOccuredEventArgs(ex));
            }
        }
