如何基于application_stop_time_output生成含item与整数型stdout的字典列表

需要从给定的application_stop_time_output输出结果中创建一个字典列表，每个字典仅包含item和stdout字段，且stdout需为整数类型。

执行的Ansible代码 #

- debug:
     msg: "{{ application_stop_time_output }}"

实际输出结果 #

期望输出结果 #

ok: [ebppdoxs10] => {
    "msg": {
          "results": [
            {
               "item": "[1/19/23 21:05:04:013 GMT+5:30] 0000 ApplicationMg A WSVR220I: Application stopped: ActivePackProdTest_war", 
               "stdout": 1674142504, 
            }, 
            {
              "item": "[1/19/23 20:04:04:013 GMT+5:30] 0000 ApplicationMg A WSVR220I: Application stopped: ActivePackProdTest_war", 
              "stdout": 1674138844, 
           }
        ]
    }
}

实现代码 #

使用Ansible的过滤器组合即可完成需求，示例代码如下：

- debug:
    msg:
      results: "{{ application_stop_time_output.results | map('combine', {'stdout': item.stdout | int}) | map('pick', 'item', 'stdout') | list }}"

代码说明 #

• map('pick', 'item', 'stdout')：从每个结果字典中仅提取item和stdout两个字段
• map('combine', {'stdout': item.stdout | int})：将原字典中的字符串类型stdout转为整数后，合并回原字典
