MVC Hangfire 授权 Ninject

Question

我想将我的自定义服务注入到 Hangfire AuthorizationFilter 中并用它做一些事情，但我遇到了问题，我的服务始终为空。

Owin 启动 class :

 public class Startup
{

    public void Configuration(IAppBuilder app )
    {
        GlobalConfiguration.Configuration
            .UseSqlServerStorage("SomeContext")
            .UseNinjectActivator(new Bootstrapper().Kernel);

        app.UseHangfireDashboard("/hangfire", new DashboardOptions { AuthorizationFilters = new[] { new RestrictiveAuthorizationFilter() } });
        app.UseHangfireServer();
    }
}

自定义过滤器：

public class RestrictiveAuthorizationFilter : IAuthorizationFilter
{

    [Inject]
    public IUserService _userService { get; set; }

    public bool Authorize(IDictionary<string, object> owinEnvironment)
    {

      //do something with _userService but it is always null

      return true;
    }
}

Ninject 内核：

 private static void RegisterServices(IKernel kernel)
    {
        kernel.Bind(x => { x.From(typeof(BookService).Assembly).SelectAllClasses().EndingWith("Service").BindDefaultInterface(); });
        kernel.Bind<LibraryDBContext>().ToSelf().InRequestScope();
        kernel.Bind<IBackgroundJobClient>().To<BackgroundJobClient>();
    }

我没有看到我的错误，你能帮我吗？

您可以将内核作为参数传递给 RestrictiveAuthorizationFilter 构造函数并请求 IUserService。

public class RestrictiveAuthorizationFilter : IAuthorizationFilter 
{   
    public IUserService _userService { get; set; }

    public RestrictiveAuthorizationFilter(IKernel kernel)
    {
        _userService = kernel.Get<IUserService>()
    }

    public bool Authorize(IDictionary<string, object> owinEnvironment)
    {

      //do something with _userService but it is always null

      return true;
    }
}
