【问题描述】：

我有一个带有 JQ 的脚本 bash，但不知道如何执行查询以获得以下结果：

conversationId(1),participantId(1),participantName(1),sessionId(1) conversationId(1),participantId(2),participantName(2),sessionId(2) conversationId(1),participantId(3),participantName(3),sessionId(3) conversationId(2),participantId(4),participantName(4),sessionId(4) . . . conversationId(n),participantId(n),participantName(n),sessionId(n)

我的文件：data.json

                        } ]
                } ]
        } ]
}

我的查询 jq：

jq 。 '{conversationId: .conversations[].conversationId, 参与者ID： .conversations[].participants[].participantId,participantName: .conversations[].participants[].participantName} |加入（“，”）'

但是conversationId 和participantName 字段会重复多次...

【问题讨论】：

部分参与者没有姓名。
抱歉，显然它没有格式化，我应该已经更正了，希望您能指导我
jq 具有内置 CSV 支持；见@csv。如果您尝试使用 join 来模拟它，那么极端情况（围绕引号、带有文字逗号或引号的字段等）将是错误的。
@CharlesDuffy 感谢您的观察

【解决方案1】：

根据您的输入，以下过滤器：

.conversations[]
| [.conversationId]
  + (.participants[] | [.participantId, .participantName])

产生：

[
  "cxx-cccc-4444-9999-b11111111",
  "2aaaa-1555-4590-99aa-4yyyyyyy",
  null
]
[
  "cxx-cccc-4444-9999-b11111111",
  "e9e9e9-d777-4a4a-8989-aeaeaeaeae",
  "Namek, Sayayin"
]
[
  "09090909-6b60-8888-xxxx-9yyyyyyyy",
  "xxxc-cccc1-4123-7777-343434343e",
  null
]

变体

请注意，上述过滤器不使用任何 jq 变量。有时介绍它们会有所帮助，因此可能会感兴趣以下变体：

.conversations[]
| (.participants | range(0;length)) as $j
| [.conversationId]
  + (.participants[$j] | [.participantId, .participantName])

在jq手册的帮助下，你应该可以从这里拿到它。

附录

ParticipantId(1),sessionId(1),mediaType(1),sessionId(1),ani(1),dnis(1)

我不太清楚你为什么要sessionsId 两次，但以下对应于你的第二个请求：

.conversations[].participants[]
| [.participantId] +
   (.sessions[] | [.sessionId, .mediaType, .sessionId, .ani, .dnis])

【讨论】：

嗨@peak 一个问题，如果我想进入“会话”并将“participantId”保留为初始字段....例如：ParticipantId(1),sessionId(1),mediaType(1 ),sessionId(1),ani(1),dnis(1) ..... 我欠你一条命.....
