使用AWS Lambda fn订阅亚马逊SNS主题，即SNS.Subscribe()

Question

我想向主题发送SNS订阅请求以进行电子邮件订阅，由于我是Lambda的新手，你能告诉我需要导入哪些库以及需要触发哪些函数吗。

提前谢谢。

Answer 1

1. 导入Boto3包

2. 创建对SNS Boto 的引用

3. 创建SNS主题

4. 为该SNS主题创建一个电子邮件发件人。(确保你遵循python中的缩进。这是一个正在运行的代码(

   import boto3
   snsClient =  boto3.client('sns')
   def lambda_handler(event, context):
   topicName = "myFirstTopic"
   emailId= "[e-mail]"
   #creating Topic and if it already created with the specified name, that topic's ARN is returned without creating a new topic..
   snsArn = createSNSTopic(topicName)   
   #crearting a subscriber for the specified SNS Toic
   snsEndpointSusbcribe(snsArn,emailId)
   
   #Function to create SNS Topic 
   def createSNSTopic(topicName):
   try:
   response = snsClient.create_topic(
   Name=topicName
   )
   print(response['TopicArn'])
   return response['TopicArn']
   except Exception as ex:
   print(ex)
   #Function to create SNS Subscriber for that Topic
   def snsEndpointSusbcribe(snsArn,emailId):
   response = snsClient.subscribe(
   #
   TopicArn=snsArn,
   Protocol='email',
   Endpoint=emailId,
   )
