我正在尝试从下面的 json 输出中获取 cpucapacity/cpuused 值，Ansible 模块收到空白消息或错误
I am trying to get the cpucapacity/cpuused value from the below json output from Ansible module am getting blank msg or error

我正在使用下面的过滤器
注册：cluster_info
- 调试：msg="{{ cluster_info.json_query('clusters[].resource_summary.cpuCapacityMHz')}}"
您的查询无效，因为 cluster_info["clusters"] 是字典，而不是列表。要求 clusters[] 没有任何意义。试试这个：
- debug:
msg: "{{ cluster_info|json_query('clusters.*.resource_summary[].cpuCapacityMHz') }}"
您可以在 JMESPath 规范中阅读有关 wildcard expressions 的内容：
The * syntax (referred to as a hash wildcard expression) will return
a list of the hash element’s values. Any subsequent expression will
be evaluated against each individual element in the list (this is
also referred to as a projection).
我喜欢使用 jpterm 来试验 JMESPath 表达式。
