我看过一些帖子，并且配置文件存在端点连接问题，但似乎我的配置文件没问题，仍然面临问题我的 .aws/config 文件

[default]
aws_access_key_id=XXX
aws_secret_access_key=XXX
region=ap-south-1
output = text


>>> import boto3
>>> translate = boto3.client(service_name='translate',region_name='ap-south-1', use_ssl=True)
>>> result = translate.translate_text(Text="Hello, World", 
            SourceLanguageCode="en", TargetLanguageCode="de")

我使用 AdministratorAccess 创建了 IAM 用户

【问题讨论】：

配置文件存放在哪个文件夹？

【解决方案1】：

Amazon Translate 在 ap-south-1（孟买）区域不可用。这就是 boto3 无法连接到端点的原因。您需要选择支持的区域。

请参阅此链接以获取当前支持的地区列表： Amazon Translate Supported Regions

【解决方案2】：

当我的连接中断时，我遇到了同样的错误 - botocore.exceptions.EndpointConnectionError：无法连接到端点 URL：“https://ec2.us-east-2.amazonaws.com/”

连接恢复后，它可以正常工作。此错误的可能原因可能是

连接错误区域无法满足您的请求，因为每个请求都会到达 AWS 上的端点（更多详细信息可以在 https://docs.aws.amazon.com/general/latest/gr/rande.html#billing-pricing 上找到）似乎 Boto3 已经成熟到足以抛出异常，因为更恰当的原因是无法准确知道发生了什么。

此外，如果您有任何与您的配置相关的问题，那么它们中的大多数都被封装了 ClientError 异常。
