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)]

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)]

[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

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。

如果你想使用自定义角色，你可以这样做:

CustomRoles类:

public static class CustomRoles
{
    public const string Administrator = "Administrador";
    public const string User = "Usuario";
}

使用

[Authorize(Roles = CustomRoles.Administrator +","+ CustomRoles.User)]

如果你的角色很少，也许你可以把它们结合起来(为了清晰起见):

public static class CustomRoles
{
     public const string Administrator = "Administrador";
     public const string User = "Usuario";
     public const string AdministratorOrUser = Administrator + "," + User;  
}

使用

[Authorize(Roles = CustomRoles.AdministratorOrUser)]
