c# - ASP.NET MVC 6 (ASP.NET 5) 中的 Application_PreSendRequestHeaders 和 Application_BeginRequest

Question

如何在 ASP.NET 5 (MVC6) 中使用这些方法。在 MVC5 中，我在 Global.asax 中使用了它……现在呢？也许是创业类？

protected void Application_PreSendRequestHeaders(object sender, EventArgs e)
        {
            HttpApplication app = sender as HttpApplication;
            app?.Context?.Response.Headers.Remove("Server");
        }

        protected void Application_BeginRequest(object sender, EventArgs e)
        {
            if (this.Request.Url.Host.StartsWith("www") || this.Request.Url.IsLoopback) return;
            var url = new UriBuilder(this.Request.Url) { Host = "www." + this.Request.Url.Host };
            this.Response.RedirectPermanent(url.ToString(), endResponse: true);
        }

谢谢!

中间件!

public void Configure(IApplicationBuilder app, ILoggerFactory loggerfactory)
{
    app.Use(next => async context =>
    {
        context.Response.Headers.Remove("Server");
        await next.Invoke(context);
    });

    app.Use(next => async context => {
        if (context.Request.Path.ToString().StartsWith("www"))
            await next.Invoke(context);
        else
            context.Response.Redirect("www" + context.Request.Path.ToString());
    });
}

这是一个很好的tutorial .
