我正在尝试创建一个权限属性以在我的控制器的每个操作中进行配置,因此这个自定义属性应该从用户那里获取 sessionId。我的代码是这样的:
public class PermissionChecker: ActionFilterAttribute
{
private int _permissionId { get; set; }
private IUserSelectorService _userService { get; set; }
public PermissionChecker(int permissionId)
{
_permissionId = permissionId;
_userService = new UserSelectorService();
}
public PermissionChecker(int permissionId, IUserSelectorService userService)
{
_permissionId = permissionId;
_userService = userService;
}
public override void OnActionExecuting(HttpActionContext actionContext)
{
if (_userService.HasPermission(_permissionId, /* here I must pass the session["Id"]*/)){
base.OnActionExecuting(actionContext);
return;
}
throw new HttpException(401, "Unauthorized");
}
}
