添加Startup.cs

public class Startup
{
public void Configuration(IAppBuilder app)
{
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<Startup>(baseUrl);
