Answers:
另一种选择是在发布时使用单个授权过滤器,但删除内部引号。
[Authorize(Roles="members,admin")]
如果要使用自定义角色,可以执行以下操作:
CustomRoles
类:
public static class CustomRoles
{
public const string Administrator = "Administrador";
public const string User = "Usuario";
}
用法
[Authorize(Roles = CustomRoles.Administrator +","+ CustomRoles.User)]
如果您的角色很少,也许可以将它们组合在一起(为清楚起见),如下所示:
public static class CustomRoles
{
public const string Administrator = "Administrador";
public const string User = "Usuario";
public const string AdministratorOrUser = Administrator + "," + User;
}
用法
[Authorize(Roles = CustomRoles.AdministratorOrUser)]
一种可能的简化方法是将其子类化AuthorizeAttribute
:
public class RolesAttribute : AuthorizeAttribute
{
public RolesAttribute(params string[] roles)
{
Roles = String.Join(",", roles);
}
}
用法:
[Roles("members", "admin")]
从语义上讲,它与吉姆·施密希尔(Jim Schmehil)的答案相同。
对于MVC4,请在角色中使用Enum
(UserRoles
),然后使用custom AuthorizeAttribute
。
根据我的控制动作,我会执行以下操作:
[CustomAuthorize(UserRoles.Admin, UserRoles.User)]
public ActionResult ChangePassword()
{
return View();
}
我使用这样的自定义AuthorizeAttribute
:
[AttributeUsage(AttributeTargets.Method | AttributeTargets.Class, Inherited = true, AllowMultiple = true)]
public class CustomAuthorize : AuthorizeAttribute
{
private string[] UserProfilesRequired { get; set; }
public CustomAuthorize(params object[] userProfilesRequired)
{
if (userProfilesRequired.Any(p => p.GetType().BaseType != typeof(Enum)))
throw new ArgumentException("userProfilesRequired");
this.UserProfilesRequired = userProfilesRequired.Select(p => Enum.GetName(p.GetType(), p)).ToArray();
}
public override void OnAuthorization(AuthorizationContext context)
{
bool authorized = false;
foreach (var role in this.UserProfilesRequired)
if (HttpContext.Current.User.IsInRole(role))
{
authorized = true;
break;
}
if (!authorized)
{
var url = new UrlHelper(context.RequestContext);
var logonUrl = url.Action("Http", "Error", new { Id = 401, Area = "" });
context.Result = new RedirectResult(logonUrl);
return;
}
}
}

另一个明确的解决方案是,您可以使用常量来保持约定并添加多个[Authorize]属性。看一下这个:
public static class RolesConvention
{
public const string Administrator = "Administrator";
public const string Guest = "Guest";
}
然后在控制器中:
[Authorize(Roles = RolesConvention.Administrator )]
[Authorize(Roles = RolesConvention.Guest)]
[Produces("application/json")]
[Route("api/[controller]")]
public class MyController : Controller
Authorize
属性采用AND语义,并且需要满足所有条件(即,用户必须同时具有管理员和来宾角色)。
如果您发现自己经常使用这两个角色,则可以将它们包装在自己的“授权”中。这实际上是已接受答案的扩展。
using System.Web.Mvc;
public class AuthorizeAdminOrMember : AuthorizeAttribute
{
public AuthorizeAdminOrMember()
{
Roles = "members, admin";
}
}
然后将您的新授权应用于该操作。我认为这看起来更干净并且易于阅读。
public class MyController : Controller
{
[AuthorizeAdminOrMember]
public ActionResult MyAction()
{
return null;
}
}
添加子类更好的代码 AuthorizeRole.cs
[AttributeUsage(AttributeTargets.Method | AttributeTargets.Class, Inherited = true, AllowMultiple = true)]
class AuthorizeRoleAttribute : AuthorizeAttribute
{
public AuthorizeRoleAttribute(params Rolenames[] roles)
{
this.Roles = string.Join(",", roles.Select(r => Enum.GetName(r.GetType(), r)));
}
protected override void HandleUnauthorizedRequest(System.Web.Mvc.AuthorizationContext filterContext)
{
if (filterContext.HttpContext.Request.IsAuthenticated)
{
filterContext.Result = new RedirectToRouteResult(
new RouteValueDictionary {
{ "action", "Unauthorized" },
{ "controller", "Home" },
{ "area", "" }
}
);
//base.HandleUnauthorizedRequest(filterContext);
}
else
{
filterContext.Result = new RedirectToRouteResult(
new RouteValueDictionary {
{ "action", "Login" },
{ "controller", "Account" },
{ "area", "" },
{ "returnUrl", HttpContext.Current.Request.Url }
}
);
}
}
}
如何使用
[AuthorizeRole(Rolenames.Admin,Rolenames.Member)]
public ActionResult Index()
{
return View();
}
使用AspNetCore 2.x,您必须走一些不同的方式:
[AttributeUsage(AttributeTargets.Method | AttributeTargets.Class, Inherited = true, AllowMultiple = true)]
public class AuthorizeRoleAttribute : AuthorizeAttribute
{
public AuthorizeRoleAttribute(params YourEnum[] roles)
{
Policy = string.Join(",", roles.Select(r => r.GetDescription()));
}
}
像这样使用它:
[Authorize(YourEnum.Role1, YourEnum.Role2)]
Intent promptInstall = new Intent(android.content.Intent.ACTION_VIEW);
promptInstall.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
promptInstall.setDataAndType(Uri.parse("http://10.0.2.2:8081/MyAPPStore/apk/Teflouki.apk"), "application/vnd.android.package-archive" );
startActivity(promptInstall);
