json - 如何解决警告 :The value 4 (type int) in a string field was converted to u'4' (type string) in Ansible?

Question

我已经解码了 Ansible 剧本中的额外变量。我将额外的变量作为编码格式传递。我正在解码额外的变量并解析我代码中的键和值。代码是:

meta="{"hostname":"oracleserver","username":"root","password":"admin@123","new_disk":"/dev/sdb","vg_name":"ts","lv_name":"tsdev","mnt_point":"/dev/sdb1","lv_size":"3G"}"

我已将编码后的元变量作为 base64encode 传递，如下所示:

ansible-playbook init.yml -e meta=eyJob3N0bmFtZSI6Im9yYWNsZXNlcnZlciIsInVzZXJuYW1lIjoicm9vdCIsInBhc3N3b3JkIjoiYWRtaW5AMTIzIiwibmV3X2Rpc2siOiIvZGV2L3NkYiIsInZnX25hbWUiOiJ0cyIsImx2X25hbWUiOiJ0c2RldiIsIm1udF9wb2ludCI6Ii9kZXYvc2RiMSIsImx2X3NpemUiOiIzRyJ9

- name: creating the custom inventory at run time   
  hosts: localhost
  tasks:
    - name: Getting the meta json data
      set_fact:
        decoded_meta_data: "{{ meta | b64decode }}"
    - name: extracting the  hostname from meta data
      set_fact:
        hostname: "{{ decoded_meta_data.hostname }}"
    - debug: msg="{{ decoded_meta_data}} {{ decoded_meta_data.hostname}} {{ decoded_meta_data.lv_size }}"

解码值后，我得到输出和警告:

PLAY [creating the custom inventory at run time] ****************************************************************************************************

TASK [Gathering Facts] ******************************************************************************************************************************
ok: [localhost]

TASK [Getting the meta json data] *******************************************************************************************************************
ok: [localhost]

TASK [extracting the  hostname from meta data] ******************************************************************************************************
ok: [localhost]

TASK [debug] ****************************************************************************************************************************************
ok: [localhost] => {
    "msg": "{'username': u'root', 'mnt_point': u'/dev/sdb1', 'new_disk': u'/dev/sdb', 'lv_name': u'tsdev', 'hostname': u'oracleserver', 'vg_name': u'ts', 'lv_size': u'3G', 'password': u'admin@123'} oracleserver 3G"
}

[WARNING]: The value 4 (type int) in a string field was converted to u'4' (type string). If this does not look like what you expect, quote the entire value to ensure it does not change.

您可以在 ~/.ansible.cfg 的默认部分添加以下行

/etc/ansible/ansible.cfg
[defaults]
string_conversion_action = ignore
