小编Lew*_*ers的帖子

我知道这里还有其他关于此问题的帖子，但我仍在努力寻找正确的解决方案。我正在尝试使用以下 python 脚本下载 S3 存储桶（我有权访问）中的一组特定对象。运行脚本时，第一个对象成功下载，但随后抛出此错误 (403)：

botocore.exceptions.ClientError: An error occurred (403) when calling the HeadObject operation: Forbidden

请参阅下面我的代码：

import csv
import boto3
import re
import logging
from botocore.exceptions import ClientError

prod_number_array_bq = []
prod_number_array_s3 = []
with open('bq-results-20191218-151637-rshujisvqrri.csv') as csv_file:
    csv_reader = csv.reader(csv_file,delimiter=',')
    line_count = 0
    for row in csv_reader:
        sliced = re.sub("[^0-9]", "", str(row))
        prod_number_array_bq.append(sliced)

s3 = boto3.resource('s3')
bucket = s3.Bucket('********')

for key in bucket.objects.all():
    sliced = re.sub("[^0-9]", "", str(key.key))
    if((set(sliced) & set(prod_number_array_bq))!=""):
            bucket.download_file(key.key,sliced + '.txt')

如有帮助，将不胜感激:)

谢谢

有人可以告诉我为什么我SMTPServerDisconnected("Connection unexpectedly closed")从以下代码中收到错误吗？
