推荐答案

要使用boto3通过帐户B中存在的SQS订阅帐户A中存在的SNS主题，请执行以下步骤.

In order to subscribe a SNS topic present in Account A by an SQS present in Account B using boto3, following is the procedure.

在帐户A中，创建SNS主题并添加适当的权限. 例如，

In Account A, create SNS topic and add the proper permission. For example,

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.

Now to subscribe the created topic from Account B, execute the following code from account B.

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"
            )

现在您将看到帐户B订阅了帐户A的SNS主题.

Now you would see the SNS topic of account A been subscribed by account B.
