Answer 3

这是我使用的“ExitHttpsIfNotRequired”属性：

[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);
    }
}
