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",

有没有办法重现相同的数组，但使用jq将键转换为小写？

Answer 1

简短的回答是肯定的，假设您指的是ASCII字符。

在您提及的特定情况下，您可以使用此过滤器：

with_entries( .key |= ascii_downcase )

但是，你提到了数组。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可能没有它。如果你想使用walk/1，你可以通过google搜索在jq中找到它的定义：jq def walk

以下是如何使用它的：

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

使用jq将所有json键转换为小写
