Question

我正在尝试设置我的依赖注入，我需要从ASP.NET身份注入IAuthenticationManager到OwinContext。

为此，我来自Global.asax -> ServiceConfig.Configure()正在运行：

 container.Register(() => HttpContext.Current.GetOwinContext().Authentication);

但是当我运行我的应用程序时，我收到了这条消息：

在上下文中找不到owin.Environment项目

为什么Global.asax无法使用此HttpContext.Current.GetOwinContext（）？

Startup.cs

[assembly: OwinStartupAttribute(typeof(MyApp.Web.Startup))]
namespace Speedop.Web
{
    public partial class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            ConfigureAuth(app);
        }
    }
}

Startup.Auth.cs

public partial class Startup
{
    public void ConfigureAuth(IAppBuilder app)
    {
        app.UseCookieAuthentication(new CookieAuthenticationOptions
        {
            AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
            LoginPath = new PathString("/Account/Login"),
            Provider = new CookieAuthenticationProvider
            {
                OnValidateIdentity = SecurityStampValidator.OnValidateIdentity<UserManager<User, int>, User, int>(
                    validateInterval: TimeSpan.FromMinutes(30),
                    regenerateIdentityCallback: (manager, user) => manager.CreateIdentityAsync(user, DefaultAuthenticationTypes.ApplicationCookie),
                    getUserIdCallback: (id) => (Int32.Parse(id.GetUserId()))
                    )
            }
        });

        app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);
    }
}

我用以下内容解决了这个问题：

container.RegisterPerWebRequest(() =>
{
    if (HttpContext.Current != null && HttpContext.Current.Items["owin.Environment"] == null && container.IsVerifying())
    {
        return new OwinContext().Authentication;
    }
    return HttpContext.Current.GetOwinContext().Authentication;

});

似乎启动时不存在OwnContext，所以我等待它并在其存在时注入它。请注意，container.IsVerifying()

中存在SimpleInjector.Advanced

如何从Global.asax获取OwinContext？
