json - 使用 JQ 将所有 json 键转换为小写

Question

我希望将带有数组的 JSON 文件摄取到我的数据库中。带有数组项的 json 文件如下:-

   {
  "campaignId": "11067182",
  "campaignName": "11067182",
  "channelId": "%pxbid_universal_site_id=!;",
  "channelName": "%pxbid_universal_site_id=!;",
  "placementId": "%epid!",
  "placementName": "%epid!",
  "publisherId": "%esid!",
  "publisherName": "%esid!",
  "hitDate": "2017-03-23",
  "lowRiskImpressions": "61485",
  "lowRiskPct": "64.5295",
  "moderateRiskImpressions": "1887",
  "moderateRiskPct": "1.9804",
  "highRiskImpressions": "43",
  "highRiskPct": "0.0451",
  "veryHighRiskImpressions": "860",
  "veryHighRiskPct": "0.9026",
  "totalRated": "95274",
  "unrated": "8",
  "unratedPct": "0.0084",
  "visibleCount": "64283",
  "pctVisible": "67.4660",
  "invisibleCount": "30999",
  "totalImpressions": "95282"
}
{
  "campaignId": "11067182",
  "campaignName": "11067182",
  "channelId": "%pxbid_universal_site_id=!;",
  "channelName": "%pxbid_universal_site_id=!;",
  "placementId": "%epid!",
  "placementName": "%epid!",
  "publisherId": "%esid!",
  "publisherName": "%esid!",
  "hitDate": "2017-03-22",
  "lowRiskImpressions": "17929",
  "lowRiskPct": "52.9379",
  "moderateRiskImpressions": "1872",
  "moderateRiskPct": "5.5273",
  "highRiskImpressions": "9",
  "highRiskPct": "0.0266",
  "veryHighRiskImpressions": "139",
  "veryHighRiskPct": "0.4104",
  "totalRated": "33850",
  "unrated": "18",
  "unratedPct": "0.0531",

有没有办法重现相同的数组，但使用 jq 将键转换为小写字母?

Answer 1

简短的回答是肯定的，假设您指的是 ASCII 字符。

在您提到的特定情况下，您可以使用此过滤器:

with_entries( .key |= ascii_downcase )

但是，您提到了数组。如果您指的是 JSON 数组，则必须修改上述内容。

一种可能性是使用 walk/1 ，但你的 jq 可能没有。如果您想使用 walk/1 ，你可以通过谷歌搜索在 jq 中找到它的定义:jq def walk

以下是它的使用方法:

walk(if type=="object" then with_entries(.key|=ascii_downcase) else . end)
