好吧,我最终选择了我原始帖子评论中描述的解决方案,这被证明是最轻松的方法。
总结一下(代码的所有功劳归功于Luke Sampsons,我只是在这里重新发布以供快速参考)这基本上是代码:
public class ExitHttpsIfNotRequiredAttribute : FilterAttribute, IAuthorizationFilter
{
public void OnAuthorization(AuthorizationContext filterContext)
{
// abort if it's not a secure connection
if (!filterContext.HttpContext.Request.IsSecureConnection) return;
// abort if a [RequireHttps] attribute is applied to controller or action
if (filterContext.ActionDescriptor.ControllerDescriptor.GetCustomAttributes(typeof(RequireHttpsAttribute), true).Length > 0) return;
if (filterContext.ActionDescriptor.GetCustomAttributes(typeof(RequireHttpsAttribute), true).Length > 0) return;
// abort if a [RetainHttps] attribute is applied to controller or action
if (filterContext.ActionDescriptor.ControllerDescriptor.GetCustomAttributes(typeof(RetainHttpsAttribute), true).Length > 0) return;
if (filterContext.ActionDescriptor.GetCustomAttributes(typeof(RetainHttpsAttribute), true).Length > 0) return;
// abort if it's not a GET request - we don't want to be redirecting on a form post
if (!String.Equals(filterContext.HttpContext.Request.HttpMethod, "GET", StringComparison.OrdinalIgnoreCase)) return;
// redirect to HTTP
string url = "http://" + filterContext.HttpContext.Request.Url.Host + filterContext.HttpContext.Request.RawUrl;
filterContext.Result = new RedirectResult(url);
}
}
public class RetainHttpsAttribute:FilterAttribute{}
该ExitHttpsIfNotRequired
属性可用于装饰用于派生 Web 应用程序中所有控制器的基本控制器类。
