Question

我已经搜索了以下问题的答案。我可以找到一些相关的答案，但不幸的是不能解决我的问题。

我从调试win_find任务中的寄存器中取出了这个json：

    - name: find docs older than 15 days
        win_find:
          paths: '{{ main_dir }}\{{ item }}\docs'
          age: 15d
        loop: '{{ all_folders}}'
        register: register_files

    - debug:
        var: register_files

这是调试输出（我已删除一些属性以使代码更短且更易于解释）：

    "register_files": {
    "changed": false, 
    "msg": "All items completed", 
    "results": [
        {
            "_ansible_item_label": "folder_1", 
            "changed": false, 
            "examined": 378, 
            "files": [
                {
                    "attributes": "Archive", 
                    "checksum": "0351d8fffad7a16a5c21136ac5a77b33931237ad", 
                    "creationtime": 1568633779.2339206, 
                }, 
                {
                    "attributes": "Archive", 
                    "checksum": "d25dd0915fe825790c8c3a27acdf6f5b34f6686b", 
                    "creationtime": 1568633767.7103796, 
            "item": folder_1", 
            "matched": 302
        }, 
            "_ansible_item_label": "folder_2", 
            "changed": false, 
            "examined": 266, 
            "files": [
                {
                    "attributes": "Archive", 
                    "checksum": "0351d8fffad7a16a5c21136ac5a77b33931237ad", 
                    "creationtime": 1568633779.2339206, 
                }, 
                {
                    "attributes": "Archive", 
                    "checksum": "d25dd0915fe825790c8c3a27acdf6f5b34f6686b", 
                    "creationtime": 1568633767.7103796, 
            "item": folder_2", 
            "matched": 125

因为代码查找两个不同的文件夹，所以我将结果作为两个不同的字典列表返回。我如何将它们组合为一个，以便获得结果：

            "files": [
                {
                    "attributes": "Archive", 
                    "checksum": "0351d8fffad7a16a5c21136ac5a77b33931237ad", 
                    "creationtime": 1568633779.2339206, 
                }, 
                {
                    "attributes": "Archive", 
                    "checksum": "d25dd0915fe825790c8c3a27acdf6f5b34f6686b", 
                    "creationtime": 1568633767.7103796, 
                {
                    "attributes": "Archive", 
                    "checksum": "0351d8fffad7a16a5c21136ac5a77b33931237ad", 
                    "creationtime": 1568633779.2339206, 
                }, 
                {
                    "attributes": "Archive", 
                    "checksum": "d25dd0915fe825790c8c3a27acdf6f5b34f6686b", 
                    "creationtime": 1568633767.7103796,

Answer 1

这是您要找的吗？

my_files: "{{ register_files.results|json_query('[].files')|flatten }}"

（未经测试）

Answer 2

获得所需结果的一种简单方法是将json_query filter与正确的jmespath表达式一起使用

.and()
.exceptionHandling()
.accessDeniedHandler(accessDeniedHandler())

这已针对您的示例中采用的以下数据结构进行了测试，并已修复为以正确的json结尾。

    - name: Get file info
      debug:
        msg: "{{ register_files | json_query('results[].files[]') | list }}"

请确保您在以后的问题中检查自己的MCVE。

结合json寄存器会导致ansible
