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",
"visibleCount": "19967",

}
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?
最佳答案
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)
关于json - 使用 JQ 将所有 json 键转换为小写，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/43038453/
