Ansible中如何根据键值合并2JSON
How to merge 2 JSON based on the key value in Ansible
我有 2 个 JSON，如下所示。我想根据子网值比较 JSON1 和 JSON2，如果 subnet in JSON1 & localsubnet 在 JSON2 匹配中，然后我想从 JSON2 复制特定本地子网下的行（useVpn）并将其放在 JSON1 中的子网下。请找到预期的结果。

这里的人们通常期望您提供一个您已经尝试过的示例实现，如果您想在这里度过一些美好的时光，您应该认真考虑下一个问题（阅读 how to ask and creating an MCVE）。
同时，因为我也知道 ansible 中的数据操作很容易让初学者迷失方向，这里有可能得到你的结果，它会引入几个你需要经历一次或另一次的过滤器和模块。
我强烈建议您阅读以下文档章节以理解下面的示例：
以下剧本：
---
- hosts: localhost
gather_facts: false
vars:
json1: [ { "applianceIp": "1.1.1.3", "subnet": "1.1.1.1/28" } ]
json2: { "hubs": [ { "hubId": "abs", "useDefaultRoute": true } ], "mode": "spoke", "subnets": [ { "localSubnet": "1.1.1.1/28", "useVpn": true }, { "localSubnet": "0.0.0.0/0", "useVpn": false } ] }
tasks:
- name: Combine corresponding UseVpn value to each element in json1 inside the result variable
vars:
vpn_value: >-
{{
json2.subnets
| selectattr('localSubnet', '==', item.subnet)
| map(attribute='useVpn')
| first
| default(false, true)
}}
set_fact:
result: >-
{{
result | default([])
+
[item | combine({'useVpn': vpn_value})]
}}
loop: "{{ json1 }}"
- name: Show the result
debug:
var: result

这里的人们通常期望您提供一个您已经尝试过的示例实现，如果您想在这里度过一些美好的时光，您应该认真考虑下一个问题（阅读 how to ask and creating an MCVE）。
同时，因为我也知道 ansible 中的数据操作很容易让初学者迷失方向，这里有可能得到你的结果，它会引入几个你需要经历一次或另一次的过滤器和模块。
我强烈建议您阅读以下文档章节以理解下面的示例：
以下剧本：
---
- hosts: localhost
gather_facts: false
vars:
json1: [ { "applianceIp": "1.1.1.3", "subnet": "1.1.1.1/28" } ]
json2: { "hubs": [ { "hubId": "abs", "useDefaultRoute": true } ], "mode": "spoke", "subnets": [ { "localSubnet": "1.1.1.1/28", "useVpn": true }, { "localSubnet": "0.0.0.0/0", "useVpn": false } ] }
tasks:
- name: Combine corresponding UseVpn value to each element in json1 inside the result variable
vars:
vpn_value: >-
{{
json2.subnets
| selectattr('localSubnet', '==', item.subnet)
| map(attribute='useVpn')
| first
| default(false, true)
}}
set_fact:
result: >-
{{
result | default([])
+
[item | combine({'useVpn': vpn_value})]
}}
loop: "{{ json1 }}"
- name: Show the result
debug:
var: result
