如何从ansible的列表中过滤e过滤器字符串

如何解决如何从ansible的列表中过滤e过滤器字符串

这是我使用下面的 json_query 从嵌套的 json 中过滤出来的列表

请看tmpdata的内容

{
  "content_length": "4883","status": 200,"cookies": {},"changed": false,"strict_transport_security": "max-age=15768000","x_api_total_time": "0.234s","_ansible_item_result": true,"_ansible_no_log": false,"json": {

}

我正在使用下面的 json_query 来过滤来自临时数据的输出

   - name: "search for traget fw"
     set_fact:
       job_status2: "{{ tmpdata | json_query('[json.status,json.extra_vars]') }}"

请查看上述事实的输出，您可以在列表中看到 dict，我只想过滤下面提到的预期输出

电流输出：

ok: [localhost] => {
    "msg": [
        "successful","{\"domain\": \"abc-cn-1\",\"mgmt_password\": \"admxxxxxin123\",\"mgmt_server\": \"192.168.10.20\",\"targets\": [\"abc-cn-c1\"]}"
    ]
}

预期输出：

["successful",targets": ["abc-cn-c1"]]

如果可能的话，请帮我识别一下

解决方法

如果您想继续使用 json_query，您的问题有（至少）两个答案，一个完全避开了这个问题。我们将从后者开始，因为它对我来说打字更少:-)

- set_fact:
   job_status2: '{{ [ tmpdata.json.status,(tmpdata.json.extra_vars|from_json).targets] }}'

第二个是一个稍微的变化，因为某人需要将嵌入的 JSON 解析为 dict 并且（AFAIK）JMESPath 没有这种能力

- set_fact:
    job_status2: "{{ newdata | json_query('[json.status,json.extra_vars.targets]') }}"
  vars:
    newdata: >-
     {{ tmpdata
     | combine({"json":{"extra_vars",tmpdata.json.extra_vars|from_json}},recursive=True)
     }}

我提到这个主要是为了你用 json_query 做其他事情的情况，因此知道如何强制结构对 JMESPath 更友好

最后，你可以欺骗并使用 the JMESPath literal notation 将已经 JSON 化的字符串嵌入到查询中

- set_fact:
    job_status2: "{{ newdata | json_query('[json.status,`' + newdata.json.extra_vars + '`.targets]') }}"
