python - Boto3 中的异常 - botocore.exceptions.EndpointConnectionError

Question

当尝试使用此 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):

    for b in s3.buckets.all():

奇怪的是，连接在当天早些时候工作，然后停止工作，昨天同一时间我也发生了同样的事情，所以我假设这是网络配置问题。 This question是唯一一个类似于原始发帖者所说的解决方案是取消设置 HTTP_PROXY 和 HTTPS_PROXY 的解决方案，我尝试过但没有用。

您没有正确配置 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。或者再次运行 aws configure 命令并指定正确的区域。

[default]
region = us-east-1
