Boto3 中的异常 - botocore.exceptions.EndpointConnectionError

Question

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，然后在它停止工作时昨天发生在我身上的同样的事情同时发生，所以我假设这是一个网络配置问题。 这个问题是唯一一个与原始海报所述的解决方案相似的问题是取消我尝试过的 HTTP_PROXY 和 HTTPS_PROXY 的设置，但它没有用。

Answer 1

您错误地配置了 AWS env。 检查您的~/.aws/config文件。 您一定将其错误地配置为 us-east-5，这是一个无效区域。 将其更改为us-east-1 。 或者再次运行aws configure命令并指定正确的区域。

[default]
region = us-east-1

Answer 2

我们突然发现了这个问题（返回状态代码 500）。

经过一些研究，我们发现 AWS 上有一些基础设施更新导致服务关闭。

您可以在此处找到每个区域的当前停机\\停机服务以及即将到来的停机时间

Answer 3

得到相同的 boto3 错误。

在我的例子中， config.lock和credentials.lock是在幕后创建的：

删除它们解决了问题。
