Boto3 中的异常 - botocore.exceptions.EndpointConnectionError

Question

尝试使用此 python 代码连接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，然后停止工作昨天同一时间发生在我身上的同样的事情所以我假设这是一个网络配置问题。是唯一一个与原始发帖者所说的同时取消设置 HTTP_PROXY 和 HTTPS_PROXY 的解决方案相似的解决方案，我尝试过但没有成功。

Answer 1

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

[default]
region = us-east-1

Answer 2

我们突然遇到了这个问题（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中断。

Answer 3

遇到相同的 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。
