Question

我正在使用aws lambda来加载存储在s3中的csv文件，如何逐行读取响应的内容，就像从csv.reader()读取的那样。

reader = csv.reader(f)
for line in reader:
    #do something
    line[1] = line[1].lower()

Lambda函数：

import urllib
import boto3

print('Loading function')

s3 = boto3.client('s3')

def lambda_handler(event, context):
    bucket = event['Records'][0]['s3']['bucket']['name']
    key = urllib.unquote_plus(event['Records'][0]['s3']['object']['key'].encode('utf8'))

    response = s3.get_object(Bucket=bucket, Key=key)
    content = response['Body'].read()

    #read content line by line as a list

Answer 1

content.splitlines()会为你效力吗？

for line in content.splitlines():
    # do something with line

如何解析亚马逊lambda响应中的数据['Body']
