使用MVC中的过滤器进行用户输入验证（OnAuthorization和OnActionExecuting过滤器方法） [英] User Input validation using filter in MVC ( OnAuthorization and OnActionExecuting filter methods)

问题描述

大家好，



在MVC中，我们如何访问过滤器中的用户条目（OnAuthorization和OnActionExecuting）方法



。我的要求是



1.需要在我的自定义授权过滤器中验证凭证（表单身份验证）

2.需要做某种对OnActionExecuting过滤器中输入值的验证



谢谢

解决方案

< blockquote>

  public   sealed   class  CustomCheckAttribute：ActionFilterAttribute 
 {
  public   override   void  OnActionExecuting（ActionExecutingContext filterContext）
 {
  var  request = filterContext.HttpContext.Request; 
  var  response = filterContext.HttpContext.Response; 
  //  验证在这里 
  if （请求[  LoginId]！=  null ）
 {
 ... 
} 
} 
} 

和授权试用此 http：// stackoverflow。 com / questions / 9366085 / why-is-onauthorization-execution-before-authentication [ ^ ]

以上解决方案在OnAuthorization上也能正常工作......



公共类CustomAuthorizationAttribute：FilterAttribute，IAuthorizationFilter

{

无效IAuthorizationFilter.OnAuthorization（AuthorizationContext filterContext）

{

var request = filterContext.HttpContext.Request;

string userName = request [txtName];



filterContext.Controller.ViewBag.OnAuthorization =IAuthorizationFilter.OnAuthorization filter called;

}

}

Hi All,

In MVC , how do we access user entry in the filters(OnAuthorization and OnActionExecuting) methods

. My requirements are

1. Need to validate credential(form authentication) in my Custom Authorization filter
2. Need to do some kind of validation on the input values in OnActionExecuting filter

Thanks
Naufal.

解决方案

public sealed class CustomCheckAttribute : ActionFilterAttribute
    {
        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            var request = filterContext.HttpContext.Request;
            var response = filterContext.HttpContext.Response;
            //validation goes here
            if (request["LoginId"] != null)
            { 
                ...
            }
        }
    }

and for Authorization try this http://stackoverflow.com/questions/9366085/why-is-onauthorization-executing-before-authentication[^]

Above solution works fine on OnAuthorization too...

public class CustomAuthorizationAttribute : FilterAttribute, IAuthorizationFilter
{
void IAuthorizationFilter.OnAuthorization(AuthorizationContext filterContext)
{
var request = filterContext.HttpContext.Request;
string userName = request["txtName"];

filterContext.Controller.ViewBag.OnAuthorization = "IAuthorizationFilter.OnAuthorization filter called";
}
}
