[英]How to get cookies from HttpActionContext on AuthorizeAttribute custom class?
[英]How to get the name of the role from the Controller to the Custom AuthorizeAttribute class?
我正在开发MVC应用程序,并将ASP.NET身份用作用户角色。 我将AuthorizeAttribute类的3个功能重写为:
public class CustomAuthorizeAttribute : AuthorizeAttribute
{
private ApplicationDbContext context = new ApplicationDbContext();
private readonly string[] allowedroles;
public CustomAuthorizeAttribute(params string[] roles)
{ this.allowedroles = roles; }
protected override bool AuthorizeCore(HttpContextBase httpContext)
{
string usr = httpContext.User.Identity.Name;
var userId = context.Users.Where(item => item.UserName == usr).Single().Id;
var uroles = context.Roles.ToList();
bool authorize = false;
foreach (var role in uroles)
{
var user = context.Users.Where(u => u.Roles.Any(r => r.RoleId == role.Id)).ToList();
if (user.Count() > 0)
{ authorize = true; }
}
return authorize;
}
protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext)
{ filterContext.Result = new HttpUnauthorizedResult("Access is Denied!"); }
}
现在我的控制器授权为:
[CustomAuthorize(Roles="Delete COA")]
而且即使在dbo.AspNetRoles表中时,我的代码也可以为其授权当前用户,而我没有将角色分配给名称为“ Delete COA”的当前用户。 但是由于我的CustomeAuthorizeAttribute类没有从控制器获取角色属性的名称,所以我无法按照当前用户的角色进行过滤。
而是构造函数代码
this.allowedroles = roles;
获取字符串为:
roles = {string[0]}
但在这里我需要角色的名称。 怎么了
似乎您正在使用属性作为参数。 由于AuthorizeAttribute
已经具有Role
属性,因此您可以简单地使用它。
public class CustomAuthorizeAttribute : AuthorizeAttribute
{
private ApplicationDbContext context = new ApplicationDbContext();
// you don't need the constrictor and private roles field
protected override bool AuthorizeCore(HttpContextBase httpContext)
{
// spiting different roles by ','
var roles=this.Rols.Split(',');
// rest of your code
}
}
然后您可以申请采取任何行动:
[CustomAuthorize(Roles="Delete COA")]
public ActionResoult MyFancyAction(){}
或者,对于多个角色,您可以:
[CustomAuthorize(Roles="FirstRole,SecondRole,AndSoOn")]
public ActionResoult MyFancyAction(){}
