简单的注入器和 Cookie

Question

如何使用 cookie 的数据作为参数为每个请求的生命范围创建实例？

例如：

container.Register<ISampleRepository>(() => 
    new SampleRepository(
        container.GetInstance<ApplicationDbContext>(), 
        request.Cookie["Token"]));

Answer 1

正如 NightOwl888 在他的评论中所说：

Cookies are runtime data that are user specific (and already tied to the request). Dependency Injection is something that happens 1 time at application startup for all users in the composition root. It makes absolutely no sense to have a user's cookie as an input to your application configuration. Perhaps it would be better if you describe what it is you are trying to achieve with your cookie.
