如何将触发器s3存储桶动态添加到lambda函数（python boto3 API）

Question

如何使用boto3将触发器s3存储桶添加到lambda函数中，然后我想将该lambda函数附加到使用编程方式（boto3）动态创建的s3存储桶中

Answer 1

我遵循的三个步骤1）使用boto3使用add_permission API连接到aws lambda 2）还应用了get_policy 3）使用boto资源连接到S3以配置BucketNotification API，输入LambdaFunctionConfigurations

Answer 2

This worked for me:

client = boto3.client(
                    's3',
                    aws_access_key_id=AWSAccessKeyID,
                    aws_secret_access_key=AWSSecretAccessKey)

response = client.put_bucket_notification_configuration(
Bucket=bucketName,
NotificationConfiguration= {'LambdaFunctionConfigurations':[{'LambdaFunctionArn': '<MyLambdaFunctionARN>', 'Events': ['s3:ObjectCreated:*']}]})

Answer 3

The complete answer for this question with the source code is:

Functions to initiate at lambda client:

response1 = lambda1.add_permission(FunctionName='put*your*lambda*arn*here',
                               StatementId='response2-id-2',
                               Action='lambda:InvokeFunction',
                               Principal='s3.amazonaws.com',
                               SourceArn='put*your*s3*bucket*arn*here'
                              )
response2 = lambda1.get_policy(FunctionName='put*your*lambda*arn*here')

Function to initiate at the s3 bucket:

response3 = s3.put_bucket_notification_configuration(
                            Bucket='put*your*bucket-name*here',
                            NotificationConfiguration= {'LambdaFunctionConfigurations':[{'LambdaFunctionArn': 'put*your*lambda*arn*here', 'Events': ['s3:ObjectCreated:*']}]})

Your s3 trigger will be attached to you lambda.
