尝试使用 jq 搜索数组时，Array 和 String cannot have their containment checked error

Question

我有一个 json 文件，大致如下所示：

{
    "default": [
        {
            "name" : "Joe Bloggs",
            "email" : "joe.bloggs@business.org"
        }
    ],
    "groups": [
        {
            "recipients" : [
                {
                    "name" : "Jane Bloggs",
                    "email" : "jane.bloggs@business.org"
                }
            ],
            "orgs" : [  
                "Service A",
                "Service B",
                "Service C"
            ]
        },
        {
            "recipients" : [
                {
                    "name" : "Bill Gates",
                    "email" : "bill.gates@business.org"
                }
            ],
            "orgs" : [
                "Service D",
                "Service E"
            ]
        },
        {   
            "recipients" : [
                {
                    "name" : "Steve Jobs",
                    "email" : "steve.jobs@me.com"
                }
            ],
            "orgs" : [
                "Service F",
                "Service G"
            ]
        }
    ]
}

使用 jq 我希望能够使用其中一个组织进行搜索，例如 'Service A' 和 return 只有收件人信息

我可以使用 jq 轻松搜索收件人，例如：

cat /path/to/file.json | jq -r '.groups[] | .recipients[] | select(.name | contains("Jobs"))' )

到return

{
  "name": "Steve Jobs",
  "email": "steve.jobs@me.com"
}

但是，如果我尝试通过 orgs 数组进行搜索，则会出现错误：

cat /path/to/file.json | jq -r '.groups[] | select(.orgs | contains("Service A"))' )

jq: error (at <stdin>:46): array (["Service A...) and string ("Service A") cannot have their containment checked

是否可以用 jq 做我正在寻找的东西？

Answer 1

而不是 contains 你需要 index ^[docs] 来检查是否有一个值为 [=16 的索引=]:

.groups[] | select(.orgs | index("Service A"))

将输出：

{
  "recipients": [
    {
      "name": "Jane Bloggs",
      "email": "jane.bloggs@business.org"
    }
  ],
  "orgs": [
    "Service A",
    "Service B",
    "Service C"
  ]
}

我们可以将其扩展为仅输出 recipients，如下所示：

.groups[] | select(.orgs | index("Service A")) | .recipients | first

我们使用 first 来 select 来自 .recipients 数组的第一个对象。输出将是：

{
  "name": "Jane Bloggs",
  "email": "jane.bloggs@business.org"
}
