尝试使用JQ处理json数据：Elasticsearch批量索引api

Question

这个问题来自以下帖子：

Elasticsearch 散装 JSON 数据

jq -c -r ".[]" C:\setting-es.json | while read line; do echo '{"index":{}}'; echo $line; done > bulk.json

上面的 jq shell 命令抛出错误“Missing statement body in do loop”

我试图改变语法，但它仍然不起作用。 我正在尝试编写 shell 脚本来为 elasticsearch 的批量 api 转换以下数据：

[{
    "codeId": "111",
    "association": [{
        "associationId": 123,
        "businessUnitsAssociationId": 1,
        "financialBusinessUnits": "DCS",
        "businessApprovalLimit": [{
            "businessApprovalLimitApprovalLimitId": 1,
            "itemMinAmount": "0.00",
            "itemMaxAmount": "0.00"
        }, {
            "businessApprovalLimitApprovalLimitId": 2,
            "itemMinAmount": "0.00",
            "itemMaxAmount": "0.00"
        }, {
            "businessApprovalLimitApprovalLimitId": 3,
            "itemMinAmount": "0.00",
            "itemMaxAmount": "0.00"
        }]
    }]
}]

我正在尝试将其转换为以下内容：

{"index":{}}
[{"codeId":"111","association":[{"associationId":123,"businessUnitsAssociationId":1,"financialBusinessUnits":"DCS","businessApprovalLimit":[{"businessApprovalLimitApprovalLimitId":1,"itemMinAmount":"0.00","itemMaxAmount":"0.00",},{"businessApprovalLimitApprovalLimitId":2,"itemMinAmount":"0.00","itemMaxAmount":"0.00",},{"businessApprovalLimitApprovalLimitId":3,"itemMinAmount":"0.00","itemMaxAmount":"0.00",}]}]

Answer 1

这是修改后问题的答案，在更正无效的 JSON 之后（即，在删除两个多余的逗号之后）。

仍然不需要 shell 循环。

在 bash 或类似 bash 的提示下：

jq -c '.[] | ({"index":{}}, [.])'  input.json

在 Powershell 提示符下，将 jq 程序放入文件中并使用-f FILENAME选项调用 jq 可能更容易。

Answer 2

[此回复基于原始问题。]

不需要任何 shell 循环：

$ jq -c '{"index":{}},.' input.json
{"index":{}}
{"str field":"some string","int field":12345,"bool field":true}
{"index":{}}
{"str field":"another string","int field":42,"bool field":false}
{"index":{}}
{"str field":"random string","int field":3856452,"bool field":true}
{"index":{}}
{"str field":"string value","int field":11111,"bool field":false}
{"index":{}}
{"str field":"last string","int field":54321,"bool field":true}
