    ]
  }
]

我想替换一些＆＃34;值＆＃34;的内容。带有来自mysql查询的数据的键，该值将前一个值作为参数。

例如，在这个对象的情况下

  {
    "item": {
      "name": "elementName",
      "type": "table",
      "displayName": "Element name",
      "operators": [
        "in",
        "not in",
        "=",
        "<>",
        "like"
      ],
      "values": []
    },
    "operator": "in",
    "value": [
      "NEHVN_3_NOIRSC3_1",
      "NGNHU_5_NGNHU_5_1",
      "NMVL381_NMDC381_1",
      "XGR_MA1_NMDC381_1"
    ],
    "conjunction": "or",
    "level": 2,
    "userFriendlyValue": [
      "NEHVN_3_NOIRSC3_1",
      "NGNHU_5_NGNHU_5_1",
      "NMVL381_NMDC381_1",
      "XGR_MA1_NMDC381_1"
    ]
  },

如果mysql查询返回

      183213,
      834924,
      986312,
      987312

对象将成为

  {
    "item": {
      "name": "elementName",
      "type": "table",
      "displayName": "Element name",
      "operators": [
        "in",
        "not in",
        "=",
        "<>",
        "like"
      ],
      "values": []
    },
    "operator": "in",
    "value": [
      183213,
      834924,
      986312,
      987312
    ],
    "conjunction": "or",
    "level": 2,
    "userFriendlyValue": [
      "NEHVN_3_NOIRSC3_1",
      "NGNHU_5_NGNHU_5_1",
      "NMVL381_NMDC381_1",
      "XGR_MA1_NMDC381_1"
    ]
  },

我打算用jq＆＃34;＃0;＆＃34;。[0]＆＃34;循环遍历第一个数组。 ＆＃34; [1]＆＃34;并在循环中连接生成的json。

是否有更聪明或更好的方式？我可以看到jq有循环，但我没有成功使用它们。

2 个答案:

答案 0 :(得分：0)

jq 解决方案：

假设新值以包含逗号分隔项的字符串形式出现。变量new_values将包含这些新值。

export new_values="736231,937213,297312,923723,913346,642354,844737,398301,943401,472312,483423,483324,432123,394610,473412,472311,956121,786052,879411,461223,123999,598111,865511,987917,576914,691044,765991,987152,979166,987111,283113,987999,112311,768123,687688,987123,212000,198623,897777,123111,387661,662111,190231,761900"

jq --arg new_vals "$new_values" '.[] | if(.item.name == "elementName" and .operator == "in")
                   then .value |= ($new_vals | split(",")) else empty end' input.json

输出：

以下是使用jq和--argfile选项的一般解决方案。首先创建一个替换表，但是你喜欢。 e.g。

[
  {
    "from": ["NEHVN_3_NOIRSC3_1","NGNHU_5_NGNHU_5_1","NMVL381_NMDC381_1","XGR_MA1_NMDC381_1"],
    "to":   [183213, 834924, 986312, 987312]
  }
]

如果此表位于repl.json文件中，则您的数据位于data.json，以下过滤器位于filter.jq

文件中 
  $replacements[] as $r
| map(if .value==$r.from then .value=$r.to else . end)

然后命令

$ jq -M --argfile replacements repl.json -f filter.jq data.json

将生成带有替换值的输出。
