以下输入的震动规格是什么？

Question

我有以下输入，并且需要使所有对象在输出中单独出现，如下所示：

我的输入：

{
  "factPanel": {
    "nutrition": {
      "columns": [
        {
          "name": "Per Serving",
          "nutrients": [
            {
              "name": "Calories",
              "valueOperator": "=",
              "value": 170,
              "uom": "kcal",
              "percentDvOperator": "=",
              "percentDv": 12
            },
            {
              "name": "Saturated Fat",
              "valueOperator": "=",
              "value": 0,
              "uom": "g",
              "percentDvOperator": "=",
              "percentDv": 0
            }
          ]
        },
        {
          "name": "Per Recommended Serving",
          "nutrients": [
            {
              "name": "Calories",
              "valueOperator": "=",
              "value": 210,
              "uom": "kcal",
              "percentDvOperator": "=",
              "percentDv": 13
            }
          ]
        }
      ]
    }
  }
}

所需的正确输出：

{
  "li_nutrients" : {
    "values" : [  {
      "nutrientPercentageDailyValue" : 12,
      "nutrientValue" : "170 kcal",
      "nutrientName" : "Calories"
    }, {
      "nutrientPercentageDailyValue" : 0,
      "nutrientValue" : "0 g",
      "nutrientName" : "Saturated Fat"
    },
      {
        "nutrientPercentageDailyValue" : 13,
        "nutrientValue" : "210 kcal",
        "nutrientName" : "Calories"
      }]
  }
}

但是无论我在规范中进行什么更改，我只能实现以下目标：

{
  "li_nutrients" : {
    "values" : [ {
      "nutrientPercentageDailyValue" : [ 12, 13 ],
      "nutrientValue" : [ 170, "kcal", 210, "kcal" ],
      "nutrientName" : [ "Calories", "Calories" ]
    }, {
      "nutrientPercentageDailyValue" : 0,
      "nutrientValue" : [ 0, "g" ],
      "nutrientName" : "Saturated Fat"
    } ]
  }
}

我写的规范：

[
  {
    "operation": "shift",
    "spec": {
      "factPanel": {
        "nutrition": {
          "columns": {
            "*": {
              "nutrients": {
                "*": {
                  "name": {
                    "*": {
                      "@(2,name)": "li_nutrients.values[&3].nutrientName",
                      "@(2,percentDvOperator)": {
                        "=": {
                          "@(4,percentDv)": "li_nutrients.values[&5].nutrientPercentageDailyValue"
                        },
                        "*": {
                          "@(4,percentDvOperator)|@(4,percentDv)": "li_nutrients.values[&5].nutrientPercentageDailyValue"
                        }
                      },
                      "@(2,valueOperator)": {
                        "=": {
                          "@(4,value)|@(4,uom)": "li_nutrients.values[&5].nutrientValue"
                        },
                        "*": {
                          "@(4,valueOperator)|@(4,value)|@(4,uom)": "li_nutrients.values[&5].nutrientValue"
                        }
                      }
                    }
                  }
                }
              }
            }
          }
        }
      }
    }
  }
]

有人可以解释一下我在这里做错了什么吗？上述颠簸规格需要进行哪些更改？预先感谢！

您应该添加两个分层分区以更精细地区分元素，例如：

[
  {//partition the stuff by the indexes of "nutrients" and "columns" arrays concurrently 
    "operation": "shift",
    "spec": {
      "*": {
        "*": {
          "*": {
            "*": {
              "nutrients": {
                "*": {
                  "percentDv": "li_&2_&3_&1.nutrientPercentageDailyValue",
                  "value|uom": "li_&2_&3_&1.nutrientValue",
                  "name": "li_&2_&3_&1.nutrientName"
                }
              }
            }
          }
        }
      }
    }
  },
  {//convert arrays to simple strings(in this case "nutrientValue" is considered) 
    "operation": "modify-overwrite-beta",
    "spec": {
      "*": {
        "*": "=join(' ',@(1,&))"
      }
    }
  },
  {//add object and aray wrappers
    "operation": "shift",
    "spec": {
      "*_*_*_*": {
        "*": "&(1,1)_&(1,2).values[#2].&"
      }
    }
  }
]
