比较2json个文件，并根据第2个文件(file2.yml)将其差异复制到另一个文件中(file2.yml) |可靠的

Question

我正在尝试比较 2 个 json 文件并通过 ansible 将其差异打印到另一个文件，但无法这样做。

我试过 Copy 和 ansible.utils.fact_diff 模块，但没有成功

file1.yml

  "from": "abc@gmail.com",
  "is_enabled": "true",
  "is_local": "true",
  "is_data": "true",
  "isin_subject": "false",

file2.yml

  "from": "xyz@gmail.com",
  "is_enabled": "false",
  "is_local": "true",
  "is_data": "true",
  "isin_subject": "false",

输出：file3.yml

  "from": "xyz@gmail.com",
  "is_enabled": "false",

Answer 1

只需循环字典并比较：

source0.json:

{
"from": "abc@gmail.com",
"is_enabled": "true",
"is_local": "true",
"is_data": "true",
"isin_subject": "false"
}

source1.json:

{
    "from": "xyz@gmail.com",
    "is_enabled": "false",
    "is_local": "true",
    "is_data": "true",
    "isin_subject": "false"
}

玩书：

- hosts: localhost
  gather_facts: false
  vars:
    json0: "{{ lookup('file', 'source0.json') | from_json }}"
    json1: "{{ lookup('file', 'source1.json') | from_json }}"
  tasks:
    - name: diff
      set_fact: 
        diff: "{{ diff | d({}) | combine({item.key: item.value}) }}"
      loop: "{{ json1 | dict2items }}"
      when: item.value != json0[item.key]

    - name: display diff
      debug:
        msg: "{{ diff }}"

结果：

ok: [localhost] => {
    "msg": {
        "from": "xyz@gmail.com",
        "is_enabled": "false"
    }
}

Compare 2 json file and copy the difference of it to another file based on 2nd file(file2.yml) | ansible
