将 GuardDuty 中的 JSON 数据解析为 Slack

问题描述

您好，我正在尝试格式化消息以向我的空闲频道发送警卫值班警报。但是无法解析数据以将其打印出来。这是我的代码 当前错误涉及 ['accountID'] 不存在。

错误：

Response
{
  "errorMessage": "'accountId'","errorType": "KeyError","stackTrace": [
    "  File \"/var/task/lambda_function.py\",line 37,in lambda_handler\n    'value': event['accountId'],\n"
  ]
}

代码：

import JSON
import requests


webhook = 'https://hooks.slack.com/services/YOUR/KEY'


def send_to_slack(event):
    # Using POST from request library messgae using Webhook from
    #   Slack API which dumps event from JSON to Python String
    #   This line allows us to post new messages to your slack channel 
    #   everytime logs are collected. It prepares and indents the messages
    #   as a string 
    try:
        r = requests.post(webhook,json.dumps(event,default=str,indent=4),headers={'Content-type': 'application/json'})
        r.raise_for_status()
    except requests.exception.ConnectionError as errc:
        raise Exception(errc)
    except requests.exceptions.HTTPError as errh:
        raise Exception(errh)
    except requests.exception.Timeout as errt:
        raise Exception(errt)
    except requests.exception.RequestException as err:
        raise Exception(err)


def lambda_handler(event,context):
    # Print logs from CloudWatch
    print(json.dumps(event))

    data = {
        'attachments' : [
            {
                'fields': [
                    {
                        'title': 'Account ID','value': event['detail']['accountId'],'short': True
                    }
                    ]
            }
            ]

         } 

    send_to_slack(data)
    
    
    return {
        'statusCode': 200,'body': json.dumps('Hello from Lambda!')
    }
