【问题描述】：
我在这个问题上被困了 2 天。我有来自 api 的以下列表，并希望从塔打印最终用户更易读的内容。它应该类似于一个开关列表（infraAccPortP.attributes.name），如果有一个子列表，那么一个带有 infraHPortS.attributes.name 键和值 infraPortBlk.attributes.fromPort 的字典 这是我第一次尝试使用 ansible 来检索数据并对其进行操作，我通常只是用它来构建东西……这似乎更容易

预期结果如下所示：
switch: 101
ports:
- srvName: test
port: 12
- srvName: test2
port:13
switch: 102
ports:
- srvName: test3
port: 12
- srvName: test4
port:13

Ansible 公开了一组过滤器来处理不同类型的数据——其中一个是
from_json过滤器：stackoverflow.com/questions/40844720/json-parsing-in-ansible -
I'm terribly stuck for 2 days on this [...] this is my first attempt at using ansible to retrieve data and manipulate it=> 请分享您尝试过的方法以及实现结果的确切问题。 -
有“孩子的孩子”。添加预期结果。

我尝试创建一个 jinja2 模板，然后使用 lookup('template') 函数打印到输出。然后我尝试使用一些 set_fact 和 map(attribute="")。这开始起作用，但它变得越来越复杂。当编写它们的人难以理解事情时，是时候寻找另一种方式了。哈哈。那是一个我以前没有使用过的新过滤器，所以我会尝试一下，然后与您一起返回结果。谢谢

预期结果不是有效的 YAML。它看起来像一个字典，但是 1) 缺少根键，2) 其他键不唯一，以及 3) 缩进错误。它应该是字典列表吗？使其成为有效的YAML！
