Question

当我在Ansible中使用以下内容时，

 with_items:
        - "{{ result1.results }}"

这是结果

"stderr": "",
"stderr_lines": [],
"stdout": "Total Cases : 139, Total Success Cases : 137, Total Failure Cases : 2, Success Percent : 98.56%, ,",
"stdout_lines": ["Total Cases : 139, Total Success Cases : 137, Total Failure Cases : 2, Success Percent : 98.56%, ,"]

再次如何迭代"stdout_lines"

Answer 1

如果要迭代列表，请使用loop或with_items构造。

这是我创建的一个简单角色，用于显示ps

---
- name: Getting ps output
  shell: ps
  register: o
- name: Debug
  debug: var=o
- name: Display stdout of ps
  shell: echo "{{ item }}"
  loop: "{{ o.stdout_lines }}"
...

我使用剧本来扮演角色：

---
- hosts: localhost
  roles:
    - ps
...

以下是命令和输出：

ansible-playbook ./testps.yml

ansible文档提供了有关使用循环的更多信息。

希望这会有所帮助。
