json - Ansible 合并 2 个数组

Question

我正在尝试使用 Ansible 合并以下 2 个数组:

TASK [Show var1] ****************************************************************************
ok: [localhost] => {
    "var1": [
        {
            "id": "133"
        },
        {
            "id": "149"
        },
        {
            "id": "188"
        }
    ]
}

和

TASK [Show var2] ****************************************************************************
ok: [localhost] => {
    "var2": [
        {
            "name": "two"
        },
        {
            "name": "one"
        },
        {
            "name": "three"
        }
    ]
}

结果应该是:

    "var1": [
        {
            "id": "133",
            "name": "two"
        },
        {
            "id": "149",
            "name": "one"
        },
        {
            "id": "188",
            "name": "three"
        }
    ]

到目前为止，我为合并所做的努力……只返回了最后一对。我怎样才能合并整个数组？

Answer 1

这是一种可能的解决方案；我们使用 set_fact和 combine过滤器，循环遍历 var1|zip(var2) :

- hosts: localhost
  gather_facts: false
  vars:
    var1:
      - id: 133
      - id: 149
      - id: 188
    var2:
      - name: two
      - name: one
      - name: three

  tasks:
    - set_fact:
        var3: "{{ var3 + [item[0]|combine(item[1])] }}"
      vars:
        var3: []
      loop: "{{ var1|zip(var2)|list }}"

    - debug:
        msg: "{{ var3 }}"

(有关 set_fact 和 combine 的信息，请参阅文档)。

这将输出:

PLAY [localhost] *****************************************************************************************************************************************************************************

TASK [set_fact] ******************************************************************************************************************************************************************************
ok: [localhost] => (item=[{'id': 133}, {'name': 'two'}])
ok: [localhost] => (item=[{'id': 149}, {'name': 'one'}])
ok: [localhost] => (item=[{'id': 188}, {'name': 'three'}])

TASK [debug] *********************************************************************************************************************************************************************************
ok: [localhost] => {
    "msg": [
        {
            "id": 133,
            "name": "two"
        },
        {
            "id": 149,
            "name": "one"
        },
        {
            "id": 188,
            "name": "three"
        }
    ]
}

PLAY RECAP ***********************************************************************************************************************************************************************************
