jq:错误:无法添加数字和字符串 [英] jq: error: number and string cannot be added

问题描述

我想从jq输出下面打印成员和id的值:

I'd like to print the value of members and id from below jq output:

$ cat test_|jq -r '.[] | select(.name=="AAA") | .'
{
  "name": "AAA",
  "members": 10,
  "profiles": 0,
  "templates": 0,
  "ldapGroups": 0,
  "ldapMembers": 0,
  "id": "20"
}

不幸的是，它仅适用于其中之一:

Unfortunately it works for one of each only:

$ cat test_|jq -r '.[] | select(.name=="AAA") | .members'
10

带有+" +我收到错误:

with +" "+ I get error:

$ cat test_|jq -r '.[] | select(.name=="AAA") | .members+" "+.id'
jq: error: number and string cannot be added

推荐答案

我建议使用 字符串插值 .如有必要，它将自动将输入转换为字符串:

I recommend to use string interpolation. It will automatically cast input to a string if necessary:

jq -r '.[]|select(.name=="AAA")|"\(.members) \(.id)"' file.json
