        {
            app.UseErrorPage();

            var config = GetWebApiConfig();
            app.UseWebApi(config);

            app.UseFileServer(new FileServerOptions()
            {
                RequestPath = PathString.Empty,
                FileSystem = new PhysicalFileSystem(@".www")
            });

            app.UseWelcomePage("");
        }

        private HttpConfiguration GetWebApiConfig()
        {

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

            config.Routes.MapHttpRoute(
                name: "Request",
                routeTemplate: "api/crawler/request",
                defaults: new { controller = "CrawlerApi", action = "request" }
            );

            config.Routes.MapHttpRoute(
                name: "ServerInfo",
                routeTemplate: "api/crawler/server/info",
                defaults: new { controller = "CrawlerApi", action = "serverinfo" }
            );

            //config.Formatters.JsonFormatter.MediaTypeMappings.Add(new QueryStringMapping("datatype", "json", "application/json"));

            config.Formatters.Remove(config.Formatters.XmlFormatter);

            config.Formatters.JsonFormatter.SerializerSettings = new Newtonsoft.Json.JsonSerializerSettings()
            {
                NullValueHandling = Newtonsoft.Json.NullValueHandling.Ignore
            };

            return config;
        }
    }

在启动项目下添加www文件夹 并在其中建立 index.html 内容随意

将index.html 复制到输出目录属性设置为 如果较新则复制

调用如下代码启动Owin网站

WebApp.Start(baseUrl);
