Question

我得到的错误：

ERROR:boto:Unable to read instance data, giving up
Traceback (most recent call last):

File "<ipython-input-62-476f799f9e0f>", line 2, in <module>

此错误消息在与aws S3Connection建立连接时即将发生。

我想与AWS S3建立连接并读取CSV文件。请帮帮我我正在使用Python 2.7.12

现在我正在使用以下代码：

import boto
import time

from boto.s3.connection import S3Connection
conn = S3Connection('<aws access key>','<aws secret key>')
print conn


from boto.s3.connection import Location
print '\n'.join(i for i in dir(Location) if i[0].isupper())

conn.create_bucket('egp-shared-prod/egp-prod-c2c1/',
    location=Location.DEFAULT)

并且，它显示错误：

 File "<ipython-input-69-4b49d719d4ca>", line 15, in <module>
conn.create_bucket('egp-shared-prod/egp-prod-c2c1/', location=Location.DEFAULT)

Answer 1

我尝试了您的代码，我的测试发现该错误与egp-shared-prod/egp-prod-c2c1/的存储桶名称有关。

Bucket Restrictions and Limitations文档说：

存储桶名称可以包含小写字母，数字和连字符。

不允许使用斜杠。此外，他们似乎正在扰乱boto代码。

Answer 2

您正在使用的Boto（官方AWS Python绑定）希望您将AWS_ACCESS_KEY_id和AWS_SECRET_ACCESS_KEY保存在环境变量中，如下所示：

export AWS_ACCESS_KEY_ID='AK123' export AWS_SECRET_ACCESS_KEY='abc123'

使用AWS S3时在Python中的凭据问题
