        }
      ]
    }
  ]
}

同样需要震动规范。还请建议任何好的教程都可以使用。需要以下信息。1.在列表中添加默认值2.根据其他字段的条件设置字段值3.String append函数可以在JOLT中使用吗？4.将对象转换为数组

能否请您推荐 JOLT 规范？

我正在从这个网站学习 - http://jolt-demo.appspot.com - 很少有非常有用的例子。
第二个来源是页面 https://github.com/bazaarvoice/jolt/issues 上的文档和查看问题
下面是规范，检查它是否是你所指的，下面是一些评论 - 我希望你能理解其余的:
