如何在ConfigureServices中访问ISecretKeyReader

public interface ISecretKeyReader
{
    string GetSecretKey();
}

public class SecretKeyReader : ISecretKeyReader
{
    public string GetSecretKey()
    {
        // 在这里读取秘钥或敏感信息的逻辑
        // 返回秘钥或敏感信息
        return "your_secret_key";
    }
}

public void ConfigureServices(IServiceCollection services)
{
    // 注册ISecretKeyReader接口的实现类
    services.AddSingleton<ISecretKeyReader, SecretKeyReader>();

    // 其他服务的注册
    // ...
}

public class MyController : Controller
{
    private readonly ISecretKeyReader _secretKeyReader;

    public MyController(ISecretKeyReader secretKeyReader)
    {
        _secretKeyReader = secretKeyReader;
    }

    public IActionResult Index()
    {
        string secretKey = _secretKeyReader.GetSecretKey();
        // 使用秘钥进行相关操作

        return View();
    }
}
