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?

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>

对于上面的@Joe,“这是给我一个重定向循环。在我添加代码之前,它工作得很好。有什么建议吗?——乔11月8日11月4点13分

这种情况也发生在我身上,我认为发生的情况是有一个负载均衡器在Web服务器前终止SSL请求。因此,我的Web站点总是认为请求是“http”,即使原始浏览器要求它是“https”。

I admit this is a bit hacky, but what worked for me was to implement a "JustRedirected" property that I could leverage to figure out the person was already redirected once. So, I test for specific conditions that warrant the redirect and, if they are met, I set this property (value stored in session) prior to the redirection. Even if the http/https conditions for redirection are met the second time, I bypass the redirection logic and reset the "JustRedirected" session value to false. You'll need your own conditional test logic, but here's a simple implementation of the property:

    public bool JustRedirected
    {
        get
        {
            if (Session[RosadaConst.JUSTREDIRECTED] == null)
                return false;

            return (bool)Session[RosadaConst.JUSTREDIRECTED];
        }
        set
        {
            Session[RosadaConst.JUSTREDIRECTED] = value;
        }
    }

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。

using System;

namespace HttpsOnly
{
    /// <summary>
    /// Redirects the Request to HTTPS if it comes in on an insecure channel.

    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

            // 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>

如果SSL支持在您的站点中不可配置(例如。应该能够打开/关闭https) -你可以在任何你希望保护的控制器/控制器动作上使用[RequireHttps]属性。
