自定义AuthorizationHandler HandleRequirementAsync未调用

Question

我无法弄清楚为什么我的授权不会成功。

我在研究潜在原因时发现了这一点：

https://github.com/aspnet/Security/issues/1103

似乎OP有类似的问题，尽管我的问题甚至与基于资源的授权无关。

这是我的代码：

AuthorizationHandler：

public class DebugOrDeveloperRequirementHandler : AuthorizationHandler<DebugOrDeveloperRequirement>
{
    private readonly IHostingEnvironment _environment;

    public DebugOrDeveloperRequirementHandler(IHostingEnvironment environment)
    {
        // breakpoint here - does get hit
        _environment = environment;
    }

    /// <inheritdoc />
    protected override Task HandleRequirementAsync(AuthorizationHandlerContext context, DebugOrDeveloperRequirement requirement)
    {
        // breakpoint here but never hit
        if (_environment.IsDevelopment() || _environment.IsIntegrationTest() || context.User.IsInRole(Constants.RoleNames.Developer))
            context.Succeed(requirement);

        return Task.CompletedTask;
    }
}

需求：

public class DebugOrDeveloperRequirement : IAuthorizationRequirement
{

}

Startup.cs代码：

        services.AddAuthorization(config =>
        {
            config.AddPolicy(ApplicationPolicyNames.Contractor, builder =>
            {
                builder.AddAuthenticationSchemes(JwtBearerDefaults.AuthenticationScheme)
                    .RequireAuthenticatedUser()
                    .RequireRole(DataLayer.Setup.Constants.RoleNames.Contractor, DataLayer.Setup.Constants.RoleNames.Developer, DataLayer.Setup.Constants.RoleNames.Admin);
            });

            config.AddPolicy(ApplicationPolicyNames.Customer, builder =>
            {
                builder.AddAuthenticationSchemes(JwtBearerDefaults.AuthenticationScheme)
                    .RequireAuthenticatedUser()
                    .RequireRole(DataLayer.Setup.Constants.RoleNames.Customer, DataLayer.Setup.Constants.RoleNames.Developer, DataLayer.Setup.Constants.RoleNames.Admin);
            });

            config.AddPolicy(ApplicationPolicyNames.Administrator, builder =>
            {
                builder.AddAuthenticationSchemes(JwtBearerDefaults.AuthenticationScheme)
                    .RequireAuthenticatedUser()
                    .RequireRole(DataLayer.Setup.Constants.RoleNames.Developer, DataLayer.Setup.Constants.RoleNames.Admin);
            });

            config.AddPolicy(ApplicationPolicyNames.Developer, builder =>
            {
                builder.AddAuthenticationSchemes(JwtBearerDefaults.AuthenticationScheme)
                    .RequireAuthenticatedUser()
                    .RequireRole(DataLayer.Setup.Constants.RoleNames.Developer);
            });

            config.AddPolicy(ApplicationPolicyNames.DeveloperOrDebug, builder =>
            {
                builder.AddAuthenticationSchemes(JwtBearerDefaults.AuthenticationScheme)
                    .Requirements.Add(new DebugOrDeveloperRequirement());
            });
        });
services.AddSingleton<IAuthorizationHandler, DebugOrDeveloperRequirementHandler>();

我的代码与文档看起来并没有什么不同。因此，我无法真正理解为什么不调用AuthorizationHandler。

那么现在我觉得很傻 - 我认为动作授权属性覆盖控制器属性 - 他们没有。

我的控制器有一个开发人员策略 - 在该处理程序执行转向之前使操作失败。
