使用ansib时如何从dict获取值返回

Question

我最近打算用ansible调用vraapi。我可以使用uri模式从API获取json结果返回。但是，在将请求发布到API之前，如何获取id的“Reboot a machine.”值（“07831a32-0bc7-4f7d-8372-164ea69d61af”）。你知道吗

这里的逻辑是先循环content项，然后保存id值（“07831a32-0bc7-4f7d-8372-164ea69d61af”）在匹配关键字时注册（重新启动计算机）

但是代码并没有像我期望的那样工作。你知道吗

有人能帮我提些建议吗。如何处理这个问题。你知道吗

- name: get actions list
  uri: xxxxxxx
      ......
  register: actions


- name: var_aaa
  when: actions.json.content[{{ item }}]['description'] == "Delete a snapshot of this machine."
  with_sequence: start=0 end={{ (actions.json.content|count) -1 }}
  register: actions.json.content[{{ item }}]['id']

这里是示例json

我使用任务的“block”来获取“id”的值，所以在block下创建一个任务，这样就可以在块内的所有任务中使用id的值。你知道吗

tasks:
 - name: Getting actions list
   block: 
    - name: get actions list
      uri: xxxxxxx
      ......
      register: actions

    - name: Saving the id value in the variable id
      set_fact:
        id={{ item.id }}
      when: "'Power off a machine' in item.description"
      with_items:
       "{{ actions.json.content }}"
    - name: Printing the Value of id
      debug: var=id
