无法使用 Jolt 转换转换为以下格式 json

Question

无法使用 jolt 实现上述输出格式并经历了多个 SO 问题，但找不到类似的问题。尝试在 jolt spec 数组中添加索引，但没有成功。在此先感谢并在下面找到输入、输出和震动规格

输入：

{
  "test1": "Student",
  "School": {
    "Syllabus": {
      "Midterm": {
        "inclusions": {
          "includedSubjectsList": {
            "Subjects": [
              {
                "subjectName": "MH1"
              },
              {
                "subjectName": "MH2"
              },
              {
                "subjectName": "MH3"
              },
              {
                "subjectName": "MH4"
              }
            ]
          }
        }
      }
    }
  }
}

颠簸规格：

[
  {
    "operation": "shift",
    "spec": {
      "School": {
        "Syllabus": {
          "Midterm": {
            "inclusions": {
              "includedSubjectsList": {
                "Subjects": {
                  "*": {
                    "subjectName": "Academy[].books[]"
                  }
                }
              }
            }
          }
        }
      }
    }
  }
]

当前输出：

{
  "Academy": [
    {
      "books": [
        "MH1"
      ]
    },
    {
      "books": [
        "MH2"
      ]
    },
    {
      "books": [
        "MH3"
      ]
    },
    {
      "books": [
        "MH4"
      ]
    }
  ]
}

预期输出：

{
  "Academy": [
    {
      "books": [
        "MH1",
        "MH2",
        "MH3",
        "MH4"
      ]
    }
  ]
}

Answer 1

你几乎是对的。替换

"subjectName": "Academy[].books[]"

和

"subjectName": "Academy[0].books[]"
