Ansible unicode对象没有属性值json解析

Ansible unicode object has no attribute value json parsing

我的任务是

  - name: task name
    shell: openstack floating ip create provider --format json
    register: result

输出将采用以下 json 格式

   {
  "router_id": null,
  "status": "DOWN",
  "description": "",
  "created_at": "2017-05-24T10:49:15Z",
  "updated_at": "2017-05-24T10:49:15Z",
  "floating_network_id": "923-cc77237b08e7",
  "headers": "",
  "fixed_ip_address": null,
  "floating_ip_address": "192.*.*.*",
  "revision_number": 1,
  "project_id": "2709ad381fcf41c5bce673c916fded10",
  "port_id": null,
  "id": "c5d187elg-d269-4eae-b6ae-7d258f04983"
}  

我想做的是,只获取 floating_ip_address 并将其存储到一个变量中,以便我可以在另一个任务中使用它。

我使用以下代码来执行此操作,

- set_fact:
     address: "{{ (result.stdout | from_json | selectattr('floating_ip_address') | list | first).floating_ip_address }}"

但是我得到一个错误

   "ERROR! 'unicode object' has no attribute 'floating_ip_address'"

仅获取 ip 地址的正确格式是什么?

如果floating_ip_address不是列表,而是您输入的简单键,例如:

- set_fact:
    address: "{{ (result.stdout | from_json)['floating_ip_address'] }}"
