在Ansible中将对象列表(字符串，字符串)转换为字典(字符串，list< string>) [英] Convert list of objects (string, string) into Dictionary (string, list<string>) in Ansible

问题描述

我有一个对象列表(每个对象包含两个类型为string的属性)，我需要将其转换为Dictionary.该对象的第一个属性将成为键，该对象的第二个属性将必须组合成字符串列表.

I have a list of objects (each object contains two attributes of type string) which I need to convert into Dictionary. The first attribute of the object will become a key, the second attribute of the object would have to be combined into a list of strings.

我经历了几种解决方案，但找不到确切的需求.

I went through several solutions but couldn't find exactly what I need.

输入示例:

[
    {
        "name": "AAA",
        "value": "111"
    },
    {
        "name": "AAA",
        "value": "222"
    },
    {
        "name": "BBB",
        "value": "333"
    },
    {
        "name": "BBB",
        "value": "444"
    },
    {
        "name": "CCC",
        "value": "555"
    }
]

所需的输出(两者均可行):

[
    {
        "name": "AAA",
        "value": [ "111", "222" ]
    },
    {
        "name": "BBB",
        "value": [ "333", "444" ]
    },
    {
        "name": "CCC",
        "value": [ "555" ]
    }
]

[
    "AAA": [ "111", "222" ],
    "BBB": [ "333", "444" ],
    "CCC": [ "555" ]
]

推荐答案

以下任务

- set_fact:
    my_list: "{{ my_list|default([]) +
                 [{item.0: item.1|json_query('[].value')}] }}"
  loop: "{{ input|groupby('name') }}"
- debug:
    var: my_list

给予

"my_list": [
    {
        "AAA": [
            "111", 
            "222"
        ]
    }, 
    {
        "BBB": [
            "333", 
            "444"
        ]
    }, 
    {
        "CCC": [
            "555"
        ]
    }
]
