当我尝试进入我的本地计算机时正常工作，但是当我进入Windows server 2021 这是错误代码

  File "C:\Users\loc\AppData\Local\Programs\Python\Python39\lib\site-packages\botocore\auth.py", line 357, in add_auth
    raise NoCredentialsError
botocore.exceptions.NoCredentialsError: Unable to locate credentials

什么是问题？凭据是 100% 正确的，因为正如我所说，它在我的本地计算机上工作。 我的意思是，当我在我的计算机上运行时，Windows 10 运行正常，当我运行另一台计算机时，Windows 2012 服务器无法运行

Answer 1

尽管您在代码中提供了凭据，但您并没有在任何地方使用它。

它可以在您的本地计算机上运行，​​因为您可能已经安装并配置了 AWS CLI 凭证，并且代码将使用该配置的凭证

以下代码将在代码中使用内联凭据，但建议您使用使用部署到 AWS 的 EC2 实例配置文件设置的凭据或使用 CLI 配置的凭据

import boto3
session = boto3.Session(
    aws_access_key_id=access_key,
    aws_secret_access_key=access_secret
)

 s3_resource = session.resource("s3", region_name="eu-west-2")
