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);

使用AspNetCore 2。X，你必须走不同的路:

[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()));
    }
}

就像这样使用它:

[Authorize(YourEnum.Role1, YourEnum.Role2)]

另一种选择是使用一个单独的授权过滤器，但删除内部报价。

[Authorize(Roles="members,admin")]

您可以使用授权策略 在Startup.cs

    services.AddAuthorization(options =>
    {
        options.AddPolicy("admin", policy => policy.RequireRole("SuperAdmin","Admin"));
        options.AddPolicy("teacher", policy => policy.RequireRole("SuperAdmin", "Admin", "Teacher"));
    });

在控制器文件中:

 [Authorize(Policy = "teacher")]
 [HttpGet("stats/{id}")]
 public async Task<IActionResult> getStudentStats(int id)
 { ... }

“教师”政策接受3个角色。

对于MVC4，使用枚举(UserRoles)与我的角色，我使用自定义AuthorizeAttribute。

在我的控制行动中，我做到了:

[CustomAuthorize(UserRoles.Admin, UserRoles.User)]
public ActionResult ChangePassword()
{
    return View();
}

我使用一个自定义的AuthorizeAttribute，像这样:

[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;
        }
    }
}

[Authorize(Roles="admin")]
[Authorize(Roles="members")]

将在需要AND时工作(由问题询问)，而此答案显示OR版本。 详见https://learn.microsoft.com/en-us/aspnet/core/security/authorization/roles?view=aspnetcore-6.0#adding-role-checks
