Question

所以我找到了[RequiresHttps]属性，但是一旦你在https中你的那种卡在那里，那么试着能够对一个网址（和方案）进行操作我发现我已经结束了必须创建我自己的ExtendedController以恢复为不使用[RequireHttps]的动作的http。

只是想知道我在做什么是好的还是有更好的方法？

public class ExtendedController : Controller
{
    protected virtual void HandleHttpRequest(AuthorizationContext filterContext)
    {
        if (!string.Equals(filterContext.HttpContext.Request.HttpMethod, "GET", StringComparison.OrdinalIgnoreCase))
        {
            throw new InvalidOperationException("Cannot post between https and http.");
        }
        string url = "http://" + filterContext.HttpContext.Request.Url.Host + filterContext.HttpContext.Request.RawUrl;
        filterContext.Result = new RedirectResult(url);
    }

    protected override void OnAuthorization(AuthorizationContext filterContext)
    {
        base.OnAuthorization(filterContext);
        object[] attributes = filterContext.ActionDescriptor.GetCustomAttributes(true);
        if (!attributes.Any(a => a is RequireHttpsAttribute))
        {
            if (filterContext == null)
            {
                throw new ArgumentNullException("filterContext");
            }
            if (filterContext.HttpContext.Request.IsSecureConnection)
            {
                this.HandleHttpRequest(filterContext);
            }
        }
    }
}

你所拥有的是语法上正确的，但是建议创建一个新的Action过滤器，它继承自默认的RequireHttpsAttribute，并使用一个参数在http和https之间切换。

public class RequireHttpsAttribute : System.Web.Mvc.RequireHttpsAttribute
{
    public bool RequireSecure = false;

    public override void OnAuthorization(System.Web.Mvc.AuthorizationContext filterContext)

    {
        if (RequireSecure)
        {
            base.OnAuthorization(filterContext);
        }
        else
        {
            // non secure requested
            if (filterContext.HttpContext.Request.IsSecureConnection)
            {
                HandleNonHttpRequest(filterContext);
            }
        }
    }

    protected virtual void HandleNonHttpRequest(AuthorizationContext filterContext)
    {
        if (String.Equals(filterContext.HttpContext.Request.HttpMethod, "GET", StringComparison.OrdinalIgnoreCase))
        {
            // redirect to HTTP version of page
            string url = "http://" + filterContext.HttpContext.Request.Url.Host + filterContext.HttpContext.Request.RawUrl;
            filterContext.Result = new RedirectResult(url);
        }
    } 
}

然后，在您的操作方法或控制器上，您将使用：

[RequireHttps (RequireSecure = true)]

...

或

[RequireHttps (RequireSecure = false)]

使其更易于管理。此解决方案假设您的大多数Web应用程序使用 HTTP 方案。

创建新的操作过滤器RequiresHttp（如果NeedSsl属性未明确应用于操作或控制器，则使用HTTP），

public override void OnActionExecuting(ActionExecutingContext filterContext)
{
    HttpRequestBase req = filterContext.HttpContext.Request;
    HttpResponseBase res = filterContext.HttpContext.Response;

    bool needSsl = filterContext.ActionDescriptor.IsDefined(typeof(NeedSslAttribute), true)
                    || filterContext.ActionDescriptor.ControllerDescriptor.IsDefined(typeof(NeedSslAttribute), true);


    if (needSsl && !req.IsSecureConnection) //https: secure
    {
        var builder = new UriBuilder(req.Url)
        {
            Scheme = Uri.UriSchemeHttps,
            Port = 444
        };
        res.Redirect(builder.Uri.ToString());
    }
    else if (!needSsl && req.IsSecureConnection) //http: non secure
    {
        var builder = new UriBuilder(req.Url)
        {
            Scheme = Uri.UriSchemeHttp,
            Port = 8081
        };
        res.Redirect(builder.Uri.ToString());
    }
    base.OnActionExecuting(filterContext);
}

新的空白属性NeedSSL（用于指示）

[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = false, Inherited = true)]
public sealed class NeedSslAttribute : Attribute { }

在Global.aspx.cs中将RequiresHttp应用为全局操作过滤器

public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{
    filters.Add(new RequiresHttp());
}

现在在控制器和操作上应用NeedSslAttribute，你想在哪里使用HTTPS方案
```
[NeedSsl]
[AllowAnonymous]
public ActionResult LogOn()
```

此代码并不完美，因为操作过滤器RequiresHttp会执行多个作业，即检查NeedSsl属性并应用HTTP或HTTPS方案。如果我们可以使用两个操作过滤器RequiresHTTP和RequiresHTTPS，那会更好。

现在，如果RequiresHTTP设置为全局过滤器，并且RequiresHTTPS过滤器已应用于特定操作，则特定RequiresHTTPS过滤器会优先使用。
