Boto - AWS SNS如何提取主题的ARN号码

Question

创建AWS SNS主题时:

a = conn.create_topic(topicname)

或者已经创建了主题:

a = conn.get_all_topics()

结果是:

{u'CreateTopicResponse': {u'ResponseMetadata': {u'RequestId': u'42b46710-degf-52e6-7d86-2ahc8e1c738c'}, u'CreateTopicResult': {u'TopicArn': u'arn:aws:sns:eu-west-1:467741034465:exampletopic'}}}

问题是如何将主题的ARN作为字符串:arn:aws:sns:eu-west-1:467741034465:exampletopic？

Answer 1

import boto

def get_account_id():
    # suggested by https://groups.google.com/forum/#!topic/boto-users/QhASXlNBm40
    return boto.connect_iam().get_user().arn.split(':')[4]

def topic_arn_from_name(self, region, name):
    return ":".join(["arn", "aws", "sns", region, get_account_id(), name])
