我正在使用 S3 Select 从 S3 Bucket 读取 csv 文件并输出为 CSV。在输出中，我只看到行，但看不到标题。如何获得包含标题的输出。

import boto3

s3 = boto3.client('s3')

r = s3.select_object_content(
        Bucket='demo_bucket',
        Key='demo.csv',
        ExpressionType='SQL',
        Expression="select * from s3object s",
        InputSerialization={'CSV': {"FileHeaderInfo": "Use"}},
        OutputSerialization={'CSV': {}},
)

for event in r['Payload']:
    if 'Records' in event:
        records = event['Records']['Payload'].decode('utf-8')
        print(records)

CSV

Name, Age, Status
Rob, 25, Single
Sam, 26, Married

s3select 的输出

Rob, 25, Single
Sam, 26, Married
