IIS7模块将允许您重定向。

    <rewrite>
        <rules>
            <rule name="Redirect HTTP to HTTPS" stopProcessing="true">
                <match url="(.*)"/>
                <conditions>
                    <add input="{HTTPS}" pattern="^OFF$"/>
                </conditions>
                <action type="Redirect" url="https://{HTTP_HOST}/{R:1}" redirectType="SeeOther"/>
            </rule>
        </rules>
    </rewrite>

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。

我花了一些时间寻找有意义的最佳实践，发现下面的方法非常适合我。我希望这能帮你节省时间。

使用配置文件(例如asp.net网站) https://blogs.msdn.microsoft.com/kaushal/2013/05/22/http-to-https-redirects-on-iis-7-x-and-higher/

或者在你自己的服务器上 https://www.sslshopper.com/iis7-redirect-http-to-https.html

(简答) 下面的代码放在里面

<system.webServer> 
 <rewrite>
     <rules>
       <rule name="HTTP/S to HTTPS Redirect" enabled="true" 
           stopProcessing="true">
       <match url="(.*)" />
        <conditions logicalGrouping="MatchAny">
        <add input="{SERVER_PORT_SECURE}" pattern="^0$" />
       </conditions>
       <action type="Redirect" url="https://{HTTP_HOST}{REQUEST_URI}" 
        redirectType="Permanent" />
        </rule>
       </rules>
 </rewrite>

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)

请使用HSTS (HTTP严格传输安全)

从http://www.hanselman.com/blog/HowToEnableHTTPStrictTransportSecurityHSTSInIIS7.aspx

原答案(2015年12月4日取代)

基本上

protected void Application_BeginRequest(Object sender, EventArgs e)
{
   if (HttpContext.Current.Request.IsSecureConnection.Equals(false) && HttpContext.Current.Request.IsLocal.Equals(false))
   {
    Response.Redirect("https://" + Request.ServerVariables["HTTP_HOST"]
+   HttpContext.Current.Request.RawUrl);
   }
}

它会被放到global。asax。cs(或global。asax。vb)

我不知道如何在web.config中指定它

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。
