将变量（值）从 JSON 主体传递到 ansible 中的 URL

Question

我想将一个特定的值作为输入从 JSON 正文传递到 URI。但是我收到如下错误。请找到下面的代码，期望是将 netid = 12345 放在 netid 在 URL 中的位置为 {{ api_uri }}/networks/12345/appliance

错误：

fatal: [localhost]: FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: 'ansible.utils.unsafe_proxy.AnsibleUnsafeText object' has no attribute 'rules'\n\nThe error appears to be in '/***/firewallrules.yml': line 35, column 10, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n       - name: Firewall rule update\n         ^ here\n"}

URI 任务：

- name: Firewall rule update
         uri:
           method: PUT
           url: "{{ api_uri }}/networks/{{ netid(from firewall.json) }}/appliance"
           body: "{{ lookup('file', 'firewall.json') | from_json }}"
           body_format: json
         register: firewallresults
         ignore_errors: yes

防火墙（JSON 输入到 API）：

{
    "rules": [
                {
            "comment": "Test1.",
            "destCidr": "x.x.x.x/24",
            "srcCidr": "y.y.y.y/24",
            "netid":"12345"
        },
                        {
            "comment": "Test2",
            "destCidr": "a.a.a.a/24",
            "srcCidr": "b.b.b.b/24",
            "netid":"12345"
        }            ]
}

错误消息报告 AnsibleUnsafeText object' has no attribute 'rules' ... The error appears to be in '/***/firewallrules.yml' 但我在您的描述中找不到任何关于 .rules 或 firewallrules.yml 的信息。

关于最少的信息

I would like to pass a particular value as an input to the URI from the JSON body. ... need a solution to get the netid from my input JSON ... which will be used in the API URI

看来您的 URI 任务和 URL 参数构造有误。我创建了一个调试任务以更好地理解用例。

---
- hosts: localhost
  become: false
  gather_facts: false

  vars:

    BODY: "{{ lookup('file', 'firewall.json') | from_json }}"

  tasks:

  - name: Show BODY
    debug:
      msg: "{{ BODY }}"

  - name: Show first 'netid' for URL
    debug:
      var: BODY.rules[0].netid

  - name: Show all 'netid's for URL
    debug:
      msg: "{{ item.netid }}"
    loop: "{{ BODY.rules }}"

导致输出

TASK [Show first 'netid' for URL] ***
ok: [localhost] =>
  BODY.rules[0].netid: '12345'

TASK [Show all 'netid's for URL] ***
ok: [localhost] => (item={u'comment': u'Test1.', u'destCidr': u'x.x.x.x/24', u'netid': u'12345', u'srcCidr': u'y.y.y.y/24'}) =>
  msg: '12345'
ok: [localhost] => (item={u'comment': u'Test2', u'destCidr': u'a.a.a.a/24', u'netid': u'12345', u'srcCidr': u'b.b.b.b/24'}) =>
  msg: '12345'
