Python boto3 SNS 电子邮件格式(每个字符串换行)

Question

如何使用 AWS SNS 服务打印电子邮件中新行中的每个字符串。

如果我在 Python 输出中打印一条消息，所有字符串都在新行中:

Started copying.. snapshot_id: snap-000000aeaada0000 from: region_src to: region_dst with new snapshot_id: new_snapshot_id
Started copying.. snapshot_id: snap-000000aeaada0001 from: region_src to: region_dst with new snapshot_id: new_snapshot_id

但在一封电子邮件中，所有内容都在一行中:

Started copying.. snapshot_id: snap-05b3834aeaada5a02 from: region_src to: region_dst with new snapshot_id: new_snapshot_id Started copying.. snapshot_id: snap-012d3db747de08d1f from: region_src to: region_dst with new snapshot_id: new_snapshot_id

import boto3

region_src = 'us-east-1'
sns_arn = "arn:aws:sns:us-east-1:000000000099:AWS_LAMBDA_NOTIFICATIONS"

def copy_snapshot_src_to_dst(snapshot_id):
    message = ("Started copying.. snapshot_id: " + str(snapshot_id) + " from: " + "region_src" + " to: " + "region_dst" + " with new snapshot_id: " + "new_snapshot_id")
    #print(message)

    return message

def lambda_handler():
    snapshots_id = [('snap-000000aeaada0000', [{'Key': 'Backup_Type', 'Value': 'Demo'}, {'Key': 'Backup Initiator Rule', 'Value': 'Daily-6d-retention'}, {'Key': 'Disaster_Recovery', 'Value': 'Full'}, {'Key': 'aws:backup:source-resource', 'Value': 'FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF'}, {'Key': 'Name', 'Value': 'HOSTNAME'}]), ('snap-000000aeaada0001', [{'Key': 'Name', 'Value': 'HOSTNAME'}, {'Key': 'Backup Initiator Rule', 'Value': 'Daily-6d-retention'}, {'Key': 'Backup_Type', 'Value': 'Demo'}, {'Key': 'Disaster_Recovery', 'Value': 'Full'}, {'Key': 'aws:backup:source-resource', 'Value': 'FFFFFFFF-FFFF-FFFF-FFFF-FFFFFFFFFFFF'}])]
    message = ""

    for i in snapshots_id:
        snapshot_id = i[0]
        message += copy_snapshot_src_to_dst(snapshot_id) + '\n'
    print(message)
    send_sns(message)

def send_sns(message):
    if sns_arn:
        print("Sending SNS alert")
        sns = boto3.client("sns", region_name=region_src)
        response = sns.publish(
            TargetArn=sns_arn,
            Subject=("AWS LAMBDA NOTIFICATION"),
            Message=(message)
        )


lambda_handler()

将 '\n' 替换为 ".\n"，然后在电子邮件中 ​​- 每个字符串都在一个新行中。
