大约6个月前,我推出了一个网站,每个请求都需要通过https。当时我能找到的确保每个页面请求都是通过https的唯一方法是在页面加载事件中检查它。如果请求不是通过http,我会response.redirect("https://example.com")

有没有更好的方法,比如web。config中的一些设置?

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);
            }
        }
    }
}

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。

示例代码和文档https://github.com/saidout/saidout-aspnetcore-httpswithstricttransportsecurity#example-code

如果你不能在IIS中设置这个,我会做一个HTTP模块,为你重定向:

using System;
using System.Web;

namespace HttpsOnly
{
    /// <summary>
    /// Redirects the Request to HTTPS if it comes in on an insecure channel.
    /// </summary>
    public class HttpsOnlyModule : IHttpModule
    {
        public void Init(HttpApplication app)
        {
            // Note we cannot trust IsSecureConnection when 
            // in a webfarm, because usually only the load balancer 
            // will come in on a secure port the request will be then 
            // internally redirected to local machine on a specified port.

            // Move this to a config file, if your behind a farm, 
            // set this to the local port used internally.
            int specialPort = 443;

            if (!app.Context.Request.IsSecureConnection 
               || app.Context.Request.Url.Port != specialPort)
            {
               app.Context.Response.Redirect("https://" 
                  + app.Context.Request.ServerVariables["HTTP_HOST"] 
                  + app.Context.Request.RawUrl);    
            }
        }

        public void Dispose()
        {
            // Needed for IHttpModule
        }
    }
}

然后将其编译为DLL,将其作为项目的引用添加到web.config中:

 <httpModules>
      <add name="HttpsOnlyModule" type="HttpsOnly.HttpsOnlyModule, HttpsOnly" />
 </httpModules>

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);
            }
        }
    }
}

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>

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>
