使用ansible解析json响应

Question

我需要使用ansible解析来自API请求的json响应，然后对响应中返回的项目采取措施。这是我的剧本的一部分-

```- name: Invoke Import API
  uri: 
    url: "{{ atl_bitbucket_dataset_url }}/rest/api/1.0/migration/imports"
    user: admin
    password: "{{ atl_bitbucket_admin_password }}"
    method: POST
    follow_redirects: yes
    force_basic_auth: yes
    creates: "{{ atl_product_home_shared }}/data/migration/import/lock.file"
    body: "{ \"archivePath\": \"{{ atl_bitbucket_dataset_url | basename }}\" }"
    body_format: json
    return_content: yes
  register: response
  until: response.status == 200
  retries: 6
  delay: 15
  failed_when: response.response.json.state != 'INITIALISING'

- name: get status of import
  debug: var=response```

这是我先前运行的json响应

```TASK [bitbucket_dataset_restore : get status of import] ************************

        "x_ausername": "admin",
        "x_content_type_options": "nosniff"
    }
}```

我想检索值"state": "INITIALISING"和"id": 1。我尝试了各种方法response.response.json.state或response['response']['json']['state']。而且它没有用。谁能帮我找回这些值，以便在以后的其他任务中使用？

Answer 1

我能够通过添加is defined来解决此问题。所以我的代码看起来像这样-failed_when: output is defined and output.json is defined and output.json.state != 'INITIALISING'
