dependency-injection - 来自 Autofac 模块的 Net Core : access to appsettings. json 值

Question

AspNet 核心应用

1)这样的Autofac模块

public class AutofacModule : Module
{
    protected override void Load(ContainerBuilder builder)
    {
      //Register my components. Need to access to appsettings.json values from here
    }
}

2) step№1中的模块注册到 Startup.cs

public void ConfigureContainer(ContainerBuilder builder)
    {
       builder.RegisterModule(new AutofacModule());
    }

如何访问 appsettings.json来自 AutofacModule 的值?我需要它来在 AutofacModule 中创建我的对象并将其用于DI。

Answer 1

需要更改第 2 步

        public void ConfigureContainer(ContainerBuilder builder)
    {
        //get settigns as object from config
        var someSettings= Configuration.GetSection(typeof(SomeSettings).Name).Get<SomeSettings>();                                                    
        //put settings into module constructor 
        builder.RegisterModule(new AutofacModule(someSettings));
    }

我不知道是否是“最佳实践”方式，但它有效。
