Question

我从服务器收到一个JSON响应，如下所示：

{
    "rules": [
        {
            "id": "1234",
            "disabled": false,
            "condition": [
                "or",
                [
                    "contains",
                    [
                        "path",
                        "payload",
                        "custom_details",
                        "resolved"
                    ],
                    "Platform"
                ],
                [
                    "contains",
                    [
                        "path",
                        "payload",
                        "custom_details",
                        "firing"
                    ],
                    "Platform"
                ]
            ],
            "catch_all": false,
            "advanced_condition": [],
            "actions": [
                [
                    "route",
                    "XYZ123"
                ],
                [
                    "extract",
                    "^\\[.*\\] *([^ ]*)",
                    [
                        "path",
                        "payload",
                        "summary"
                    ],
                    "description"
                ]
            ]
        },
        {
            "id": "9876",
            "disabled": false,
            "condition": [
                "or",
                [
                    "contains",
                    [
                        "path",
                        "payload",
                        "custom_details",
                        "resolved"
                    ],
                    "Sidewalk"
                ],
                [
                    "contains",
                    [
                        "path",
                        "payload",
                        "custom_details",
                        "firing"
                    ],
                    "Sidewalk"
                ]
            ],
            "catch_all": false,
            "advanced_condition": [],
            "actions": [
                [
                    "route",
                    "QWERT1"
                ],
                [
                    "extract",
                    "^\\[.*\\] *([^ ]*)",
                    [
                        "path",
                        "payload",
                        "summary"
                    ],
                    "description"
                ]
            ]
        }
    ]

我想对此进行循环并匹配字符串Sidewalk。如果存在匹配项，则获取匹配项的id的值。

我尝试过

---
- name: API call - GET Event Rule ID
  uri:
   url: "{{ api_event_rules }}"
    method: GET
    status_code: 200
    headers:
      Content-Type: "application/json"
      Accept: "application/vnd.ap+json;version=2"
      Authorization: "Token token={{ api_token }}"
  register: json_response

我尝试了这个JMESPath

rules[*].condition[*][2]

但这给出了类似的内容：

[
[
  "Platform",
  "Platform"
],
[
  "Sidewalk",
  "Sidewalk"
],

我无法通过这条路，这对ansible来说是很新的。非常感谢您的帮助。

Q：“匹配字符串Sidewalk。如果存在匹配项，则获取匹配项的id的值。”

A：不清楚我们要寻找哪个“人行道”。让我们来第一个。下面的任务创建一个 id 字典和相应条件

- set_fact:
    ids: "{{ rules|
            json_query('[*].{key: condition[1][2], value: id}')|
            items2dict
            }}"
- debug:
    var: ids['Sidewalk']

调试给出

"ids['Sidewalk']": "9876"

如果这是有条件的任务，请在下面进行调试

- debug:
    msg: "Sidewalk found with id: {{ ids['Sidewalk'] }}"
  when: "'Sidewalk' in ids.keys()"

给予

"msg": "Sidewalk found with id: 9876"
