Ansible解析json并将结果读入不同的变量

我已经设置了一个任务，它查询github api元端点并返回以下内容

{
  "verifiable_password_authentication": true,
  "github_services_sha": "f9e3a6b98d76d9964a6613d581164039b8d54d89",
  "hooks": [
    "192.30.252.0/22",
    "185.199.108.0/22",
    "140.82.112.0/20"
  ],
  "git": [
    "192.30.252.0/22",
    "185.199.108.0/22",
    "140.82.112.0/20",
    "13.229.188.59/32",
    "13.250.177.223/32",
    "18.194.104.89/32",
    "18.195.85.27/32",
    "35.159.8.160/32",
    "52.74.223.119/32"
  ],
  "pages": [
    "192.30.252.153/32",
    "192.30.252.154/32",
    "185.199.108.153/32",
    "185.199.109.153/32",
    "185.199.110.153/32",
    "185.199.111.153/32"
  ],
  "importer": [
    "54.87.5.173",
    "54.166.52.62",
    "23.20.92.3"
  ]
}

我需要做的是获取3个钩子IP，并将它们分别读入各自的变量中

我已经尝试了一些我找到的解决方案，但似乎没有什么对我有效

---

我已经深入研究了json，所以只返回了3个IP，但是如何将它们分别取出并放入变量？

我在变量名部分使用了j2语法，并且-TIL-看起来在该部分也允许使用jinja2语法

请参阅剧本以处理

挂钩

列出变量并分配给变量

变量_1

、

变量_2

、

变量_3

等：

- hosts: localhost
  gather_facts: false
  vars:
    counter: 1
    hooks:
    - 192.30.252.0/22
    - 185.199.108.0/22
    - 140.82.112.0/20

  tasks:
    - name: populate vars
      set_fact:
        variable_{{counter}}: "{{ item }}"
        counter: "{{ counter | int + 1 }}"
      with_items:
        - "{{ hooks }}"

    - name: print vars
      debug:
        msg: "variable_1: {{variable_1}}, variable_2: {{variable_2}}, variable_3: {{variable_3}}"

以及输出：

[root@optima-ansible ILIAS]# ansible-playbook 50257063.yml 

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

TASK [populate vars] *******************************************************************************************************************************************************************************************************************

ok: [localhost] => (item=185.199.108.0/22)
ok: [localhost] => (item=140.82.112.0/20)

TASK [print vars] **********************************************************************************************************************************************************************************************************************
ok: [localhost] => {
    "msg": "variable_1: 192.30.252.0/22, variable_2: 185.199.108.0/22, variable_3: 140.82.112.0/20"
}

PLAY RECAP *****************************************************************************************************************************************************************************************************************************
localhost                  : ok=2    changed=0    unreachable=0    failed=0   

[root@optima-ansible ILIAS]# 

希望能有帮助

更新：

我注意到一件奇怪的事——也是直到——就是如果你把线颠倒过来：

variable_{{counter}}: "{{ item }}"
counter: "{{ counter | int + 1 }}"

致：

您仍然会得到相同的变量名，_1到_3，而我希望得到_2到_4

我猜ansible循环的行为与其他编程语言不同。

在循环中使用GitHub Webhook IP

- name: Query Github Meta API and get Hook Ips
  hosts: local
  connection: local
  vars:
    counter: 1
  tasks:

    - name: Query API
      uri:
        url: https://api.github.com/meta
        return_content: yes
      register: response

    - name: Populate Hook Variables
      set_fact:
        webhook_ip_{{counter}}: "{{ item }}"
        counter: "{{ counter | int + 1 }}"
      with_items:
        - "{{ response['json']['hooks'] }}"

    - name: print vars
      debug:
        msg: "Variable_1: {{ webhook_ip_1 }}, Variable_2: {{ webhook_ip_2 }}, Variable_3: {{ webhook_ip_3 }}"

非常感谢你的帮助。我基于这个答案的解决方案如下。很高兴它有帮助！如果有兴趣，请查看我添加的更新部分，了解我注意到的一件奇怪的事情
