Необходимо создать ответ на сообщение в виде таблицы и опубликовать sh в SNS через python

/ 07 августа 2020

Привет, я новичок в python, и я пытаюсь сравнить две таблицы и получить отчет по cidr, и мне нужно отправить отчет по электронной почте, используя SNS topi c, ниже код, который я написал .

Я могу получить отчет, а при публикации sh сообщение Я получаю сообщение об ошибке проверки, любые предложения, как действовать дальше, и есть ли способ отправить сообщение в виде таблицы, как показано ниже.

код: 

import json
import boto3
from boto3.dynamodb.conditions import Key, Attr
client = boto3.client('sns')


dynamodb = boto3.resource("dynamodb")
table = dynamodb.Table('cidr')
cidr_atd = dynamodb.Table('cidr_allocated')


def lambda_handler(event, context):
    # TODO implement
    main_cdr = table.scan()
    sub_cdr = cidr_atd.scan()
    regions = {}
    
    for cdr in main_cdr['Items']:
        regions[cdr['region']] = {}
        regions[cdr['region']]['provider'] = cdr['provider']
        regions[cdr['region']]['subnet'] = cdr['subnet'].split('/')[1]
        regions[cdr['region']]['cidravaliable'] = [i for i in range(int(regions[cdr['region']]['subnet']), 33)]
    
    # for key, val in regions.items():
        # print(key, ' subnet_missing : ', val['subnet_missing'])
    
    for scdr in sub_cdr['Items']:
        regions[scdr['region']]['cidravaliable'].remove(int(scdr['subnet '].split('/')[1]))
    
    #print('-' * 110)
    #print('| Region' + ' ' * 17 + '| Provider' + ' ' * 5 + '| Remaining CIDRs' + ' ' * 52 + '|')
    #print('-' * 110)
    #for key, val in regions.items():
    #    del regions[key]['subnet']
    #    region = '| ' + key
    #    provider = '| ' + val['provider']
    #    subnet_missing = '| ' + ', '.join(list(map(str, val['subnet_missing'])))
    #    print(region + ' ' * (25 - len(region)) + provider + ' ' * (15 - len(provider)) + subnet_missing + ' ' * (69 - len(subnet_missing)) + '|')
    #print('-' * 110)
    
    
    def publishOntoSNSTopic(regions):

        client.publish(
            TargetArn='arn:aws:sns:eu-west-2:333333333:test',
            Message=regions,
            Subject='test'
        )
    
    publishOntoSNSTopic(regions)
    

    return {
        'statusCode': 200,
        'body': json.dumps(regions)
    }
