ASP.NET MVC [RequireHttps] - 返回HTTP

Question

一旦你放在一個動作和用戶開關[RequireHttps]從HTTP到HTTPS，所有後續鏈接將留HTTPS ...

有沒有辦法切換回HTTP？

Answer 1

技術上相當詳細的描述，你可以做到這一點

你可以look at the source的RequireHttpsAttribute並將其逆轉。

在實踐中，你可能不應該

如果會話還活着，it is generally inadvisable to return to HTTP。這可以是foundation for a variety of attacks，例如session hijacking。

這裏的 'ExitHttpsIfNotRequired' 屬性使用：

[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method)] 
public class RetainHttpsAttribute : Attribute 
{ 
} 

public class ExitHttpsIfNotRequiredAttribute : FilterAttribute, IAuthorizationFilter 
{ 
    public void OnAuthorization(AuthorizationContext filterContext) 
    { 
     // Abort if it's not a secure connection 
     if (!filterContext.HttpContext.Request.IsSecureConnection) return; 

     if (filterContext.ActionDescriptor.ControllerDescriptor.ControllerName == "sdsd") return; 

     // Abort if it's a child controller 
     if (filterContext.IsChildAction) 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; 

     // Abort if the error controller is being called - we may wish to display the error within a https page 
     if (filterContext.ActionDescriptor.ControllerDescriptor.ControllerName == "Error") return; 

     // No problems - redirect to HTTP 
     string url = "http://" + filterContext.HttpContext.Request.Url.Host + filterContext.HttpContext.Request.RawUrl; 
     filterContext.Result = new RedirectResult(url); 
    } 
}
