              "*": "ResultSets.&1.@(3,fields[&].name)"
            }

        }
      }
    }

请帮忙。

谢谢，哈里

你几乎是对的。下面是产生预期输出的规范：

json prettyprint-override">[
  {
    "operation": "shift",
    "spec": {
      "ResultSets": {
        "*": {
          "rows": {
            "*": {
              "*": "ResultSets.&3[&1].@(3,fields[&].name)"
            }
          }
        }
      }
    }
  }
]

说明：

• &1-引用数组中对象的索引
• 相反，我们希望将它放在相同的索引下，但由向上三个级别的对象包装。这就是为什么我们使用&3[&1]
而不是 &1的原因
