1,具体的实现方法代码如下
public class CustomAuthorizeAttribute : FilterAttribute, IAuthorizationFilter{/// <summary>/// 如果需要验证权限的时候,就执行进来/// </summary>/// <param name="filterContext"></param>public void OnAuthorization(AuthorizationContext filterContext){//1.验证是否登录过object ouser = filterContext.HttpContext.Session[CacheConstant.CacheCurrentUser()];if (ouser == null || (ouser is CurrentUser) == false) //取到session或者取到的session不是CurrentUser---没有登录{ResponseResult(filterContext);}else{//就要取出当前用户的信息,通过用户信息判断,当前这个用户是否能够访问当前要访问的功能 CurrentUser currentUser = (CurrentUser)ouser;List<Tuple<string, string, string>> tupMen = currentUser.TupMenue;List<string> currentUserUrlList = tupMen.Select(c => c.Item3).Where(c => !string.IsNullOrWhiteSpace(c)).Select(c => c.ToUpper()).ToList();object ObjectControllerName = filterContext.HttpContext.Request.RequestContext.RouteData.Values["controller"];string controllerName = ObjectControllerName.ToString().ToUpper();int count = currentUserUrlList.Count(c => c.Contains(controllerName));if (count <= 0){if (filterContext.HttpContext.Request.IsAjaxRequest()) //Ajax请求{filterContext.Result = new JsonResult(){Data = new AjaxResult(){Success = false,Message = "对不起,当前功能你没有权限访问"}};}else //非Ajax请求{filterContext.Result = new RedirectResult("/Home/UnAuthorize");}}}}/// <summary>/// 没有Session的响应/// </summary>/// <param name="filterContext"></param>private static void ResponseResult(AuthorizationContext filterContext){if (filterContext.HttpContext.Request.IsAjaxRequest()) //Ajax请求{filterContext.Result = new JsonResult(){Data = new AjaxResult(){Success = false,Message = "没有登录,无法获取数据"}};}else //非Ajax请求{filterContext.Result = new RedirectResult("Account/Login");}}
2,具体在控制器引用权限认证方法
