动态添加角色以授权ASP.NET 5中控制器的属性 [英] Dynamically add roles to authorize attribute for controller in ASP.NET 5

问题描述

我对此帖子有一个示例问题动态添加角色以进行授权的属性，但对于ASP.NET 5(vNext) 在ASP.NET 5中，如上面的帖子所述，我无法覆盖AuthorizeAttribute类.那么如何在ASP.NET 5(vNext)中动态添加角色控制器

I have a sample question with this post Dynamically add roles to authorize attribute for controller but for ASP.NET 5 (vNext) In ASP.NET 5, I can not overwrite AuthorizeAttribute class as above post said. So how can I add roles dynamically Controllers in ASP.NET 5 (vNext)

提前谢谢.

推荐答案

正如迈克所说，您需要策略.这是一个实现.

As mike mentioned, you need policies. Here is one implementation.

public class CustomRoleRequirement : AuthorizationHandler<CustomRoleRequirement>, IAuthorizationRequirement
{
    protected override void Handle(Microsoft.AspNet.Authorization.AuthorizationContext context, CustomRoleRequirement requirement)
    {
        var roles = new[] { "Admin", "Admin2", "Admin3" };  //Get From DB.
        var userIsInRole = roles.Any(role => context.User.IsInRole(role));
        if (!userIsInRole)
        {
            context.Fail();
            return;
        }

        context.Succeed(requirement);
    }
}

并在startup.cs中的ConfigureServices方法中

And in the ConfigureServices method in startup.cs

services.ConfigureAuthorization(options =>{
    options.AddPolicy("CustomRole", policy => policy.AddRequirements(new CustomRoleRequirement()));
});

并且您需要像这样在控制器中提供autorize属性.

And you need to provide the autorize attribute in the controller like this.

[Authorize(Policy = "CustomRole")]
