import boto3
import os

s3 = boto3.client('s3')

def read_s3_file(bucket_name, folder_name):
    response = s3.list_objects_v2(Bucket=bucket_name, Prefix=folder_name)
    for obj in response['Contents']:
        file_name = obj['Key']
        if file_name.endswith('.txt'):  # 可以根据需要修改文件类型
            obj = s3.get_object(Bucket=bucket_name, Key=file_name)
            content = obj['Body'].read().decode('utf-8')
            print(content)

bucket_name = 'your_bucket_name'
folder_name = 'your_folder_name'
