在 bash 中使用 jq 进行嵌套 Json 解析

Question

我需要解析一个 json 文件，我将 bash 脚本与 jq 绑定在一起，但没有得到预期的输出。

Json 文件：

[
  {
    "fqdn": "my-created-lb",
    "status": "Active",
    "members": {
      "10.45.78.9:80": {
        "dc": "NA",
        "state": "enabled",
        "port": 80
      },
      "10.45.78.10:80": {
        "dc": "NA",
        "state": "enabled",
        "port": 80
      },
      "10.45.78.11:80": {
        "dc": "NA",
        "state": "enabled",
        "port": 80
      },
      "10.45.78.12:80": {
        "dc": "NA",
        "state": "enabled",
        "port": 80
      }
    }
  }
]

我需要输出为：

"my-created-lb"
"10.45.78.9:80","enabled"
"10.45.78.10:80","enabled"
"10.45.78.11:80","enabled"
"10.45.78.12:80","enabled"

我在 jq 以下尝试过，但没有得到预期的输出：

jq '.[] | .fqdn,.members,.members[].state'

但我的输出低于 :

"my-created-lb"
{
  "10.45.78.9:80": {
    "dc": "NA",
    "state": "enabled",
    "port": 80
  },
  "10.45.78.10:80": {
    "dc": "NA",
    "state": "enabled",
    "port": 80
  },
  "10.45.78.11:80": {
    "dc": "NA",
    "state": "enabled",
    "port": 80
  },
  "10.45.78.12:80": {
    "dc": "NA",
    "state": "enabled",
    "port": 80
  }
}
"enabled"
"enabled"
"enabled"
"enabled"

Answer 1

因为你想要密钥的名称，你可以像这样使用 to_entries：

jq -r '.[] | .fqdn, ( .members | to_entries | .[] | [ .key, .value.state ] | @tsv )'

输出：

my-created-lb
10.45.78.9:80   enabled
10.45.78.10:80  enabled
10.45.78.11:80  enabled
10.45.78.12:80  enabled

要获得原始 post 中列出的确切输出，请将 jq 脚本修改为：

jq -r '.[] | [.fqdn], ( .members | to_entries | .[] | [ .key, .value.state ] ) | @csv'

输出：

"my-created-lb"
"10.45.78.9:80","enabled"
"10.45.78.10:80","enabled"
"10.45.78.11:80","enabled"
"10.45.78.12:80","enabled"

Answer 2

要准确获得您想要的输出：

jq -r '.[] | ([.fqdn]|@csv), (.members | keys[] as $k | [$k, .[$k].state] | @csv)' file.json

"my-created-lb"
"10.45.78.10:80","enabled"
"10.45.78.11:80","enabled"
"10.45.78.12:80","enabled"
"10.45.78.9:80","enabled"
