Question

我正在使用以下代码创建一个存储桶。做任何事情的时候一定要写 lambda_function(event,context) 吗？

代码如下

import json
import boto3

BUCKET_NAME = 'ly_2020_s3'
def s3_client():
    s3 = boto3.client('s3')
    return s3

def create_bucket(bucket_name):
    return s3_client().create_bucket(
        Bucket=bucket_name,CreateBucketConfiguration={'LocationConstraint':'eu-central-1'})

if __name__=='__main__':
    create_bucket(BUCKET_NAME)

Answer 1

需要一个 lambda 处理函数：

• AWS Lambda function handler in Python

例如：

import json
import boto3

BUCKET_NAME = 'lilly_2020_s3'

def s3_client():

    s3 = boto3.client('s3')
    return s3

def create_bucket(bucket_name):

    return s3_client().create_bucket(
        Bucket=bucket_name,
        CreateBucketConfiguration={'LocationConstrain':'eu-central-1'})

def lambda_handler(event, context):

    bucket_name = 'some-backet-name'
    create_bucket(bucket_name)
