获取方式

1. Configuration["ConnectionString"]

2. Configuration.GetValue<string>("IsClusterEnv")

3. Configuration["Vault:Name"] //此方法未找到实例

4. Configuration.GetSection("Logging")

5. services.Configure<AppSettings>(Configuration);//实体类如下

　　　　publicclassAppSettings

    {

        publicstring MvcClient { get; set; }

        publicbool UseCustomizationData { get; set; }

 

    }
