OWIN 自托管静态网站

我们知道，借助OWIN，WebApi,SignalR,WCF 都可以创建自托管（Self-Host）实例，完全不需要IIS，静态网站也可以。

最近做一个服务器监控小工具，用 SignalR 通信，监控端是一个静态网站（挂在IIS），服务端是一个 WinForm 程序（SignalR 服务寄宿），但是我想网站也寄宿到这个 WinForm 中，这样通过 WebApp.Start 开启主机时，网站也开启了，部署也方便

为了减少配置代码，我们用一个静态文件处理的中间件 Beginor.Owin.StaticFile

Install-Package Beginor.Owin.StaticFile

在 OWIN 启动类中配置

using Beginor.Owin.StaticFile;[assembly: OwinStartup(typeof(AisinGioro.Server.OwinStartup))]
namespace AisinGioro.Server
{
public class OwinStartup
{
public void Configuration(IAppBuilder app)
{
//静态文件托管
app.Map("/wwwroot", map =>
{
// 允许跨域
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托管
app.Map("/signalr", map =>
{
// 允许跨域
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);
}); //该值表示连接在超时之前保持打开状态的时间长度。
//默认为110秒
//GlobalHost.Configuration.ConnectionTimeout = TimeSpan.FromSeconds(110); //该值表示在连接停止之后引发断开连接事件之前要等待的时间长度。
//默认为30秒
GlobalHost.Configuration.DisconnectTimeout = TimeSpan.FromSeconds();
}
}
}

其中 RootDirectory 也可以配置相对目录，比如 ../app/wwwroot

MimeTypeProvider 属性设置 MIME 映射（Content-Type），如果不设置，Beginor.Owin.StaticFile 只能能判断普通的类型（比如 html,css,js），所以还是设置下比较好

创建Web服务监听，开启主机

private void DoWork()
{
try
{
//创建WEB服务器监听
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();
} 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));
}
}
