使用 JOLT 传输 Json 输出时出现问题

Question

我遇到了以下问题：我得到了一个 JSON 输入，例如

{
 "Vorname":"Vorname1 Vorname2",
 "Name":"Nachname
}

输出应该是：

{ "such":"NachnameVorname1Vorname2" }

我的 JOLT 规格是：

 [{
    "operation": "modify-default-beta",
    "spec": {
        "FullName": "=concat(@(1,Vorname),' ' ,@(1,Name))",
        "RFullName": "=concat(@(1,Name),@(1,Vorname))"
    }
}, {
    "operation": "shift",
    "spec": {
        "PersNr": "ymitarb",
        "Austrittsdatum": "ymaust",
        "RFullName": "such",
        "FullName": "name"

    }
}, {
    "operation": "default",
    "spec": {
        "name": "${fname}",
        "such":"$(rfname)",
        "ymitarb": "${nummer}"
    }
}]

我得到的输出是：

{
    "such": "NachnameVorname1 Vorname2",
    "name": "Vorname1 Vorname2 Nachname",
    "ymitarb": ""
}

虽然应该是 {"such":"NachnameVorname1Vorname2"}

我的第二个想法是将 Vorname 拆分为 Vorname_x

[{
    "operation": "modify-default-beta",
    "spec": {
        "FullName": "=concat(@(1,Vorname),' ' ,@(1,Name))",
        "RFullName": "=concat(@(1,Name),@(1,Vorname))"
    }
}, {
    "operation": "shift",
    "spec": {
         "Vorname": {
        "* * *": {
          "$(0,1)": "Vorname_1",
          "$(0,2)": "Vorname_2",
          "$(0,3)": "Vorname_3"
        },
           "* *": {"$(0,1)": "Vorname_1",
          "$(0,2)": "Vorname_2"}


      },
        "PersNr": "ymitarb",
        "Austrittsdatum": "ymaust",
        "RFullName": "such",
        "FullName": "name"

    }
}, {
    "operation": "default",
    "spec": {
        "name": "${fname}",
        "such":"$(rfname)",
        "ymitarb": "${nummer}"
    }
}]

这里的输出是：

{
    "Vorname_1": "Vorname1",
    "Vorname_2": "Vorname2",
    "such": "NachnameVorname1 Vorname2",
    "name": "Vorname1 Vorname2 Nachname",
    "ymitarb": ""
}

我无法在 concat 中使用 Vorname_1 和 Vorname_2 的值...... 因为我找不到任何解决方案

规格

[
  {
    "operation": "shift",
    "spec": {
      // split Vorname by a space
      "Vorname": {
        "* *": {
          "$(0,1)": "vorFront",
          "$(0,2)": "vorBack"
        }
      },
      // pass Name thru
      "Name": "Name"
    }
  },
  {
    "operation": "modify-default-beta",
    "spec": {
      // concat the names now that the space is gone
      "such": "=concat(@(1,Name),@(1,vorFront),@(1,vorBack))"
    }
  }
]
