，并希望仅使用其选择器从中提取某些对象（使用jq）。
说，仅返回 .fields.user_id ==“ abc”
的记录或者，仅返回 .fields.session_id ==“ 1e2d3f”
的记录 select似乎是实现此目的的方法，但是鉴于上述JSON结构，我不确定如何用它来表达以上内容。
以下内容将产生空结果，但应返回该session_id的记录：
curl -X GET 'http://localhost:8090/xxx/api/v1/results?dr=last5days' -H 'Cache-Control: no-cache' -H 'Postman-Token: f6b819d0-f4f6-4def-bccb-3967366779c7' -H 'secret: 5a04bfef-39eb-435a-a0d0-b274592790bb' | jq '.[] | select(.fields.session_id=="1v69yiptamgse1niap51zr2o9x154169081480766b2d6b7-d3ce-4166-9292-c4669a3dfc14")'

$
尝试用jq的entries函数进行不同的组合，但效果不佳：
curl -X GET 'http://localhost:8080/xxx/api/v1/results?dr=last5days' -H 'Cache-Control: no-cache' -H 'Postman-Token: f6b819d0-f4f6-4def-bccb-3967366779c7' -H 'secret: 5a04bf34ef-39eb-435a-a0d0-b278765790bb' | jq 'with_entries(select(.value.pk==98))'
% Total % Received % Xferd Average Speed Time Time Time Current

jq: error (at <stdin>:274): Cannot use number (9) as object key
有人可以帮我创建正确的jq查询吗？ TIA。

试图实施评论中提出的建议：
此jq表达式：
map(select(.fields.user_id=="amzn1.ask.account.AHMFB2H7ZXMSCB5TLPYWCPBJGWGHFYQZ6OPPMEPQ7CT2LZXNPAFJMJELXXCCTEZ2JUE5PXRSBJHJTO3AVXT3C63AOEZLIEP3D3HIFBT5M23G4ORENFRT54AAK7I4X2HCORXJAB2UGQAHPE2TC75F2GWWZWSPO2CWEAZJJN7LJYFWEYHEJDLNQ6FSUD5LQWKBUC347K3IF32IV3I")) | length
似乎可以在JQ Playground工作（返回正确的计数 3 ）：
但在命令行上使用时，它返回错误的结果（长度为 0 的空数组）：
$ curl -X GET 'http://localhost:8080/xxx/api/v1/results?dr=last5days' -H 'Cache-Control: no-cache' -H 'Postman-Token: f6b819d0-f4f6-4def-bccb-3967366779c7' -H 'secret: 5a04bfef-39eb-435a-a0d0-b271392790bb' | jq 'map(select(.fields.user_id=="amzn1.ask.account.AHMFB2H7ZXMSCB5TLPYWCPBJGWGHFYQZ6OPPMEPQ7CT2LZXNPAFJMJELXXCCTEZ2JUE5PXRSBJHJTO3AVXT3C63AOEZLIEP3D3HIFBT5M23G4ORENFRT54AAK7I4X2HCORXJAB2UGQAHPE2TC75F2GWWZWSPO2CWEAZJJN7LJYFWEYHEJDLNQ6FSUD5LQWKBUC347K3IF32IV3I")) | length'

我还是在做错什么？
======
根据注释中的建议，以下带有debug的查询返回JSON，但仍无法产生正确的计数：
$ curl -X GET 'http://localhost:8080/xxx/api/v1/results?dr=last5days' -H 'Cache-Control: no-cache' -H 'Postman-Token: f6b819d0-f4f6-4def-bccb-3967366779c7' -H 'secret: 5a04bfef-39eb-435a-a0d0-b271392790bb' | jq ' debug | map(select(.fields.session_id=="1v69yiptamgse1niap51zr2o9x154169081480766b2d6b7-d3ce-4166-9292-c4669a3dfc14")) | length'

答案 0 :(得分：0)
-
使用jq版本1.6、1.5和1.4，我已经使用数据的JSON版本测试了jq程序，并且一切正常（在Mac上）。
-
请阅读http://stackoverflow.com/help/mcve-如果您遵循这些准则，则对于所有相关人员来说，调试，通信和/或寿命通常将大大简化。
-
我建议至少在调试时将jq程序放入文件中并使用-f命令行选项。
