Ansible'；何时'；条件不从数组返回结果

面对一个有着可解释的情况的问题。寄存器返回一个json数组列表，但“when”条件不起作用。我将解释我在这里面临的问题：

首先，我注册目录：

- name: check if log dir exists
  win_stat:
    path: some\path
  register: register_some_dir

这是寄存器输出：

"register_some_dir": {

    "changed": false,

使用json过滤器，我可以过滤如下路径：

- set_fact:
    log_paths: "{{ register_some_dir | json_query('results[*].stat.path') }}"
  when: register_some_dir.results[*].stat.exists == true

set_fact模块完全返回不带when条件的路径

但是“when”条件不接受[*]，它表示这是意外的。但它是数组所必需的

如果我将[*]从when条件中删除，它表示“stat”没有arrtibuut

---

如何将when条件设置为起作用

您必须循环检查结果并测试when条件中的每个元素

幸运的是，通过将过滤器集成到

json\u查询中的单个表达式中，您可以做您想做的事情

- set_fact:
    log_paths: "{{ register_some_dir | json_query('results[?stat.exists].stat.path') }}"
