模块初始化错误名称“事件”未定义

Question

I am trying to copy file from one bucket to another through AWS Lamda Function. My AWS S3 Trigger Setting Here is the code --->

from __future__ import print_function

    import boto3
    import json
    import time
    import urllib

    print("loadig function")
    s3 = boto3.client('s3')

    def lambda_handler(event, context):
        source_bucket = event['Records'][0]['s3']['bucket']['name']


    key = urllib.unquote_plus(event['Records'][0]['s3']['object']['key'])
    target_bucket = 'destinationstage'
    copy_source = {'Bucket': source_bucket, 'Key': key}
    try:
        print("waiting for the file persist in the source bucket")
        waiter = s3.get_waiter('object_exists')
        waiter.wait(Bucket=source_bucket, key=key)
        print(
            "copying the object from the source s3 bucket to destination s3 bucket"
        )
        s3.copy_object(Bucket=target_bucket, Key=key, CopySource=copy_source)

    except Exception as e:
        print(e)
        print(
            "Error getting object {} from bucket {}. Make sure tehy exists in the bucket"
        )
        raise e

Here is the error message I keep receiving --->

Answer 1

it's just an indentation problem. Change to:

import boto3
import json
import time
import urllib

print("loadig function")
s3 = boto3.client('s3')

def lambda_handler(event, context):
    source_bucket = event['Records'][0]['s3']['bucket']['name']


    key = urllib.unquote_plus(event['Records'][0]['s3']['object']['key'])
    ...
