//添加 json 文件路径
            var builder = new ConfigurationBuilder().SetBasePath(Directory.GetCurrentDirectory()).AddJsonFile("appsettings.json");

 

//创建配置根对象
var configurationRoot = builder1.Build();
//读取到ioc IOptions<SuperAppsettings> setting 依赖注入
services.Configure<SuperAppsettings>(configurationRoot.GetSection("super"));   // 依赖注入
