将两个嵌套的json文件合并为Json格式的单个文件

Question

我有两个json，想将一个附加到另一个json并将其保存在一个文件中。我已经完成了一个事实，可以读取值并将其放入变量中，方法如下：

- name: Set json combine to add new event
  set_fact:
     event_json_create: "{{ lookup('file', 'event_template.json') }}" 

- name: Set json combine to get the existing list of events
  set_fact:
     event_json_existing: "{{ lookup('file', 'notification.json') }}" 

现在我想将event_json_create附加到event_json_existing。

event_json_create看起来像这样：

"event_json_create": {
    "LambdaFunctionConfigurations": [{
        "Events": [
            "s3:ObjectCreated:*"
        ],
        "Filter": {
            "Key": {
                "FilterRules": [{
                    "Name": "prefix",
                    "Value": [
                        "keying_service/response/"
                    ]
                }]
            }
        },
        "LambdaFunctionArn": "arn:aws:lambda:us-east-1:*******:function:xyz"
    }]
}

event_json_existing看起来像这样：

"event_json_existing": {
           "LambdaFunctionConfigurations": [
               {
                   "Events": [
                       "s3:ObjectCreated:*"
                   ],
                   "Filter": {
                       "Key": {
                           "FilterRules": [
                               {
                                   "Name": "Prefix",
                                   "Value": "staging/inbound/Source_Contact/ac/input_fia/"
                               }
                           ]
                       }
                   },
                   "Id": "Eventtry",
                   "LambdaFunctionArn": "arn:aws:lambda:us-east-1:******:function:abc"
               }
           ]
       }

如何将两个json附加在ansible中，确保两个json都属于主要组：LambdaFunctionConfigurations，然后可以将其写入json文件。所以我期望输出：

{
    "LambdaFunctionConfigurations": [{
            "Events": [
                "s3:ObjectCreated:*"
            ],
            "Filter": {
                "Key": {
                    "FilterRules": [{
                        "Name": "prefix",
                        "Value": [
                            "keying_service/response/"
                        ]
                    }]
                }
            },
            "LambdaFunctionArn": "arn:aws:lambda:us-east-1:*******:function:xyz"
        },
        {
            "Events": [
                "s3:ObjectCreated:*"
            ],
            "Filter": {
                "Key": {
                    "FilterRules": [{
                        "Name": "Prefix",
                        "Value": "staging/inbound/Source_Contact/ac/input_fia/"
                    }]
                }
            },
            "Id": "Eventtry",
            "LambdaFunctionArn": "arn:aws:lambda:us-east-1:*******:function:abc"
        }
    ]
}

请帮助！

此模板

shell> cat events.json.j2
{{ events|to_nice_json }}

和以下任务

    - set_fact:
        events: "{{ {'LambdaFunctionConfigurations':
                     ([event_json_create.LambdaFunctionConfigurations.0] +
                      [event_json_existing.LambdaFunctionConfigurations.0])} }}"
    - template:
        src: events.json.j2
        dest: events.json

给予

shell> cat events.json 
{
    "LambdaFunctionConfigurations": [
        {
            "Events": [
                "s3:ObjectCreated:*"
            ],

                                "keying_service/response/"
                            ]
                        }
                    ]
                }
            },
            "LambdaFunctionArn": "arn:aws:lambda:us-east-1:*******:function:xyz"
        },
        {

                        }
                    ]
                }
            },
            "Id": "Eventtry",
            "LambdaFunctionArn": "arn:aws:lambda:us-east-1:******:function:abc"
        }
    ]
