使用boto for AWS S3 Buckets for Signature V4

Question

我在区域法兰克福使用Python-Boto SDK for S3 Buckets时遇到问题.据亚马逊链接,该地区仅支持V4.本文档介绍了如何为Boto SDK添加V4支持.我添加了一个新的部分:

if not boto.config.get('s3', 'use-sigv4'):
    boto.config.add_section('s3')
    boto.config.set('s3', 'use-sigv4', 'True')

然后我创建了新连接并获得了所有桶:

connection = S3Connection(accesskey, secretkey, host=S3Connection.DefaultHost)
buckets = connection.get_all_buckets()

它工作正常,但后来我试图获取我的桶的所有键:

for bucket in buckets:
    bucket.get_all_keys()

我得到以下内容:

S3ResponseError: 400 Bad Request
<?xml version="1.0" encoding="UTF-8"?>
<Error><Code>AuthorizationHeaderMalformed</Code><Message>The authorization header is malformed; the region 'us-east-1' is wrong; expecting 'eu-central-1'</Message><Region>eu-central-1</Region>

它为什么会发生？之后我连接到该地区并获得所有需要的数据:

region_con = boto.s3.connect_to_region('eu-central-1', aws_access_key_id=accesskey, aws_secret_access_key=secretkey)
bucket = region_con.get_bucket(bucket.name)
bucket.get_all_keys()

我该如何正确修理？

Answer 1

我使用Boto时遇到了同样的问题.该地区是法兰克福,错误地区出错.我的解决方案只是将主机(从此页面http://docs.aws.amazon.com/general/latest/gr/rande.html获取的URI )指向's3.eu-central-1.amazonaws .com'而不是默认's3.amazonaws.com'

s3 = boto.s3.connect_to_region('eu-central-1',
                               aws_access_key_id=accesskey,
                               aws_secret_access_key=secretkey,
                               host='s3.eu-central-1.amazonaws.com')
