Rip*_*ppo 4 c# dependency-injection simple-injector
我只是在检查我的理智。这是我使用 simpleinjector 3.3.2 的代码
Container.RegisterPerWebRequest<HttpContextBase>(() =>
{
var context = HttpContext.Current;
if (context == null && Container.IsVerifying) return new FakeHttpContext();
return new HttpContextWrapper(context);
});
Container.Verify();

...
public class FakeHttpContext : HttpContextBase { }

然而,RegisterPerWebRequest 现在被标记为已过时,我不能 100% 确定这是否是更改代码以反映新代码库的正确方法。
Container.Options.DefaultScopedLifestyle = new WebRequestLifestyle();
//So we can inject HttpContextBase into any class
Container.Register<HttpContextBase>( () =>
{
var context = HttpContext.Current;
if (context == null && Container.IsVerifying)
return new FakeHttpContext();
return new HttpContextWrapper(context);
}, Lifestyle.Scoped);

所以我的问题是“我应该使用Lifestyle.Scoped替换RegisterPerWebRequest吗?我仍然可以按原样使用代码吗?
您显示的代码是正确的。Container.Register<T>(Func<T>, Lifestyle.Scoped)取代Container.RegisterPerWebRequest<T>(Func<T>).
