【问题描述】：
我试图弄清楚如何从 F5 bigip_command_module 的标准输出结果中过滤掉池名称
bigip_command:
commands:
- "tmsh list ltm policy {{ item }}"
这是我得到的输出：
TASK [f5_maintenance : tmsh list policies] *************************************

这是我的任务。

【问题讨论】：
-
您能否提供您的任务的完整描述？尤其是你是怎么注册结果的，你是怎么得到
layer7_pools的？由于stdout_lines的内容看起来像JSON，如果你register: result并打印出"{{ result.json }}"，这样行吗？ -
是的，我只是想过滤返回值以仅获取池。我需要池信息来进一步查找池的成员及其状态。
-
经过一些研究，您似乎喜欢做JSON parsing in Ansible 和to get the values from Ansible JSON stdout。根据这个，您可以先检查
{{ layer7_pools.stdout | from_json}}的输出，看看它是否能让您更好地访问数据？ -
这是我在使用 {{ layer7_pools.stdout |从_json}}。 “在 ({{ layer7_pools.stdout | from_json}}) 上发生了意外的模板类型错误：预期的字符串或缓冲区”，“_ansible_no_log”：false
