Net Core：从Autofac模块访问appsettings.json值 [英] Net Core: access to appsettings.json values from Autofac Module

问题描述

AspNet核心应用程序

AspNet core app

1）像这样的Autofac模块

1) Autofac module like that

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

2 ）步骤№1中的模块已注册到 Startup.cs

2) Module from step№1 registered into Startup.cs

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

如何访问 appsettings.json AutofacModule 的c $ c>值？我需要在 AutofacModule 中创建对象并将其用于DI。

How to access to appsettings.json values from AutofacModule? I need that for create my objects inside AutofacModule and using it for DI.

推荐答案

需要更改步骤№2

        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，但是有效。

I don't know is "best practise" way or not, but it works.
