jq：无法使用字符串“id”索引数组

Question

我的backup.json 看起来像这样：

{
  "andres": [
    [
      {
        "id": 1,
        "email": "password",
        "username": test1,
        "password": "email@email.com",
        "name": "Dummy Account",
        "address": "123 st road",,
        "ip_address": "0.0.0.0",
        "phone": "123-123-1234",
      },
      {
        "id": 2,
        "email": "email2@email.com",
        "username": test2,
        "password": "password",
        "name": "Dummy Account",
        "address": "123 st road",,
        "ip_address": "0.0.0.0",
        "phone": "123-123-1234"
      }
    ],
  ]
}

我正在使用命令：

jq -r '.andres[] | .id, .email, .username, .password, .name, .address, .ip_address, .phone' < backup.json > backup.csv

但它给出了错误：

Cannot index array with string "id"

我希望它看起来像这样：

1,email@email.com,test1,password,Dummy Account,123 st road,0.0.0.0,123-123-1234
2,email@email.com,test2,password,Dummy Account,123 st road,0.0.0.0,123-123-1234

我是使用 JQ 的新手。有人可以修复我的命令并告诉我哪里出错了吗？

谢谢！

Answer 1

jq 是一个有趣的野兽。我发现这需要大量的尝试和错误。

修复 JSON 后

$ jq -r '.andres[][] | map(values) | @csv' file.json
1,"password","test1","email@email.com","Dummy Account","123 st road","0.0.0.0","123-123-1234"
2,"email2@email.com","test2","password","Dummy Account","123 st road","0.0.0.0","123-123-1234"

请注意，对于 id=1，您已切换密码和电子邮件值。

另见the jq manual中的“格式化字符串和转义”

Answer 2

您的 json 中 andres 的值是一个数组数组，但您正在访问它，就好像它是一个对象数组一样。您必须先展平数组（或索引）才能访问对象。然后从这些对象中，您需要将所需的值映射为 csv 值数组。

$ jq -r '
.andres[][] | [.id, .email, .username, .password, .name, .address, .ip_address, .phone] | @csv
' < backup.json > backup.csv

注意.andres[][]中的第二组[]。

您可能还想在输出中添加一些标题。

$ jq -r '
["id", "email", "username", "password", "name", "address", "ip_address", "phone"] as $headers
    | $headers, (.andres[][] | [.[$headers[]]]) | @csv
' < backup.json > backup.csv

除了这不是有效的 json（"phone": "123-123-1234", 处还有额外的,），但在删除它之后，我能够在此处获得有效的 json。
您的 json 文件中还有更多数组 [ { .. } ]，您需要通过 [][][] 考虑到这一点。
以下json：

{
  "Emails": [
    {
      "email@email.com": [
        {
          "andres": [
            [
              {
                "id": 1,
                "email": "email@email.com",
                "username": "test1",
                "password": "password",
                "name": "Dummy Account",
                "address": "123 st road",
                "ip_address": "0.0.0.0",
                "phone": "123-123-1234"
              },
              {
                "id": 2,
                "email": "email@email.com",
                "username": "test2",
                "password": "password",
                "name": "Dummy Account",
                "address": "123 st road",
                "ip_address": "0.0.0.0",
                "phone": "123-123-1234"
              }
            ],
            true
          ]
        }
      ]
    }
  ]
}

使用以下过滤器：

 .Emails[][][].andres[][] | .id, .email, .username, .password, .name, .address, .ip_address, .phone

给我：

jq: error (at <stdin>:34): Cannot iterate over boolean (true)
1
"email@email.com"
"test1"
"password"
"Dummy Account"
"123 st road"
"0.0.0.0"
"123-123-1234"
2
"email@email.com"
"test2"
"password"
"Dummy Account"
"123 st road"
"0.0.0.0"
"123-123-1234"
exit status 5

在jqplay。我不知道怎么处理json中的那个true，它是无效的，它应该是一个数组成员，比如{ "true" }。
