如何使用boto3通过另一个帐户的SQS订阅一个帐户的SNS主题?

在帐户A中,创建SNS主题并添加适当的权限。 例如

import boto3
sns_client = boto3.clien('sns')
topics = sns_client.create_topic(Name='SNS topic name')
sns_client.add_permission(
                TopicArn=str(topics['TopicArn']),
                Label=label,
                AWSAccountId=[
                    "AccountB_Id",
                ],
                ActionName=[
                    "GetTopicAttributes",
                    "SetTopicAttributes",
                    "AddPermission",
                    "RemovePermission",
                    "DeleteTopic",
                    "Subscribe",
                    "ListSubscriptionsByTopic",
                    "Publish",
                    "Receive"
                ]
            )

现在,要从帐户B订阅创建的主题,请从帐户B执行以下代码。

import boto3
subscription_client = boto3.client('sns')
subscription_client.subscribe(
                TopicArn="ARN of the topic created",
                Protocol="sqs",
                Endpoint="ARN of the SQS present in Account B"
            )

现在你会看到A账户的SNS主题已经被B账户订阅了。
