我运行一项任务，捕获多个设备的接口(interface)状态，在某些情况下捕获多个接口(interface)的状态，但我一次只能检索一个 stdout_lines，但我需要检索它运行的主机的所有 stdout_lines命令打开。我有任务代码来访问列表中各自的 stdout_lines，但不是全部。
- name: Execute IOS command to check port state up/down before configuration
ios_command:
commands:
- "show ip int brief | in {{item}}"
loop: "{{ports}}"
register: PortUpDown
- name: print port state up/down
debug:
#msg: "{{item.0 | to_nice_yaml}}"
#msg: "{{item.1 | to_nice_yaml}}"
msg: "{{item}}"
loop:
#- "{{PortUpDown.results.0.stdout_lines}}"
#- "{{PortUpDown.results.1.stdout_lines}}"
- "{{PortUpDown.results}}"
register: PortUpDown
- name: print var that capture port state up/down
debug:
var: PortUpDown
正如您所看到的，我已经评论了我在测试期间访问的项目。我最终想要的是能够访问 0,1,2,3 等而无需声明它，因为在脚本开始时我不知道它是否只是列表中的一个接口(interface)或多个接口(interface)我将获取端口状态。
输出是这样的。

最佳答案
您可以使用过滤器 map 的组合提取列表中所有元素的 stdout_lines ，然后 flatten列表的结果列表，以便执行此操作。
鉴于剧本:
- hosts: all
gather_facts: no
tasks:
- command: "echo {{ item }}"
loop:
- "Ethernet2/1 unassigned YES NVRAM administratively down down"
- "Ethernet1/1 unassigned YES NVRAM up up"
register: PortUpDown
- debug:
msg: "{{ item }}"
loop: "{{ PortUpDown.results | map(attribute='stdout_lines') | list | flatten }}"
