注意：这是我第一次在这里发帖，不知道如何正确地逐行修复...我只想访问 out.host 'centos' 并将其保存在 csv 文件中，当然我需要做更多，但这是我需要做的第一件事，请帮忙！谢谢。

---

- name: Save remote port   
  shell: echo {{ item.changed }} > /tmp/x_output.csv

  args:
    executable: /bin/bash

  with_items: "{{ out.results }}"

这是我唯一可以参考的，item.changed 为“False”，但其他的我都不能。

为什么？

答案1

正如您在发布的调试中所看到的，与键不同，列表元素中changed没有键。hostresults

字典里有一个invocation，因此：

shell: echo "{{ item.invocation.module_args.host }}" > /tmp/x_output.csv

虽然它是你自己定义的值，而不是返回值。
