您还可以通过向浏览器返回“Strict-Transport-Security”报头来使用HSTS。浏览器必须支持这一点(目前主要是Chrome和Firefox支持)，但这意味着一旦设置好，浏览器将不会通过HTTP向站点发出请求，而是在发出请求之前将它们转换为HTTPS请求。尝试结合从HTTP重定向:

protected void Application_BeginRequest(Object sender, EventArgs e)
{
  switch (Request.Url.Scheme)
  {
    case "https":
      Response.AddHeader("Strict-Transport-Security", "max-age=300");
      break;
    case "http":
      var path = "https://" + Request.Url.Host + Request.Url.PathAndQuery;
      Response.Status = "301 Moved Permanently";
      Response.AddHeader("Location", path);
      break;
  }
}

不了解HSTS的浏览器将忽略头文件，但仍然会被switch语句捕获并发送到HTTPS。

如果您正在使用ASP。你可以试试这个包:赛达。aspnetcore . httpwithstricttransport security。

然后你只需要加

app.UseHttpsWithHsts(HttpsMode.AllowedRedirectForGet, configureRoutes: routeAction);

这也会将HTTP StrictTransportSecurity头添加到所有使用https方案的请求中。

这是基于@特洛伊·亨特的更全面的回答。将这个函数添加到Global.asax.cs中的WebApplication类中:

    protected void Application_BeginRequest(Object sender, EventArgs e)
    {
        // Allow https pages in debugging
        if (Request.IsLocal)
        {
            if (Request.Url.Scheme == "http")
            {
                int localSslPort = 44362; // Your local IIS port for HTTPS

                var path = "https://" + Request.Url.Host + ":" + localSslPort + Request.Url.PathAndQuery;

                Response.Status = "301 Moved Permanently";
                Response.AddHeader("Location", path);
            }
        }
        else
        {
            switch (Request.Url.Scheme)
            {
                case "https":
                    Response.AddHeader("Strict-Transport-Security", "max-age=31536000");
                    break;
                case "http":
                    var path = "https://" + Request.Url.Host + Request.Url.PathAndQuery;
                    Response.Status = "301 Moved Permanently";
                    Response.AddHeader("Location", path);
                    break;
            }
        }
    }

(要在本地构建中启用SSL，请在项目的Properties dock中启用它)

你需要做的是:

1)在web中添加一个键。配置，取决于生产或阶段服务器如下所示

<add key="HttpsServer" value="stage"/>
             or
<add key="HttpsServer" value="prod"/>

2)在Global内部。Asax文件添加如下方法。

void Application_BeginRequest(Object sender, EventArgs e)
{
    //if (ConfigurationManager.AppSettings["HttpsServer"].ToString() == "prod")
    if (ConfigurationManager.AppSettings["HttpsServer"].ToString() == "stage")
    {
        if (!HttpContext.Current.Request.IsSecureConnection)
        {
            if (!Request.Url.GetLeftPart(UriPartial.Authority).Contains("www"))
            {
                HttpContext.Current.Response.Redirect(
                    Request.Url.GetLeftPart(UriPartial.Authority).Replace("http://", "https://www."), true);
            }
            else
            {
                HttpContext.Current.Response.Redirect(
                    Request.Url.GetLeftPart(UriPartial.Authority).Replace("http://", "https://"), true);
            }
        }
    }
}

简单地在公共类HomeController: Controller的顶部添加[RequireHttps]。

->并添加GlobalFilters.Filters。添加(新RequireHttpsAttribute ());在Global.asax.cs文件中的'protected void Application_Start()'方法中。

强制整个应用程序使用HTTPS。

这也取决于你的平衡器的品牌，对于web mux，你需要寻找http头x- webmux - ssl - terminate: true来计算传入的流量是ssl。详情:http://www.cainetworks.com/support/redirect2ssl.html
