如何在.net核心中添加索赔配置文件？

{
  "Claims": {
    "Claim1": "Value1",
    "Claim2": "Value2"
  }
}

public class Startup
{
    public IConfiguration Configuration { get; }

    public Startup(IConfiguration configuration)
    {
        Configuration = configuration;
    }

    public void ConfigureServices(IServiceCollection services)
    {
        // 读取索赔配置信息
        var claimsConfig = Configuration.GetSection("Claims").Get<ClaimsConfig>();

        // 注册索赔配置信息
        services.Configure<ClaimsConfig>(Configuration.GetSection("Claims"));

        // 在其他地方使用索赔配置信息
        services.AddSingleton(claimsConfig);
    }
}

public class ClaimsConfig
{
    public string Claim1 { get; set; }
    public string Claim2 { get; set; }
}

public class MyService
{
    private readonly ClaimsConfig _claimsConfig;

    public MyService(ClaimsConfig claimsConfig)
    {
        _claimsConfig = claimsConfig;
    }

    public void DoSomething()
    {
        // 使用索赔配置信息
        var claim1Value = _claimsConfig.Claim1;
        var claim2Value = _claimsConfig.Claim2;

        // 其他操作
    }
}
