Boto3中的异常 - botocore.exceptions.EndpointConnectionError

尝试使用此python代码连接到数据库以测试连接时.

import boto3
s3 = boto3.resource('s3')

for b in s3.buckets.all():
   print b.name

我收到了这个错误.

Traceback (most recent call last):

奇怪的是,连接在当天早些时候工作,然后在它停止工作同样的事情发生在我昨天同时所以我假设这是一个网络配置问题.这个问题是唯一与原始海报所说的解决方案类似的解决方案,即取消设置HTTP_PROXY和HTTPS_PROXY但我没有尝试.

您已正确配置AWS env.检查你的~/.aws/config文件.您必须将其错误地配置为us-east-5,这是一个无效区域.将其更改为us-east-1.或者aws configure再次运行命令并指定正确的区域.

[default]
region = us-east-1

@ vishal.k最有可能的是Boto3正在从其他地方进入该地区。检查是否在环境变量`AWS_DEFAULT_REGION`中配置了区域（如果已设置），请取消设置该区域，然后重试。请参阅：http://boto3.readthedocs.io/en/latest/guide/configuration.html
