當我嘗試運行到我的本地計算機時正常工作，但是當我進入Windows server 2021時，出現錯誤代碼

  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

什么是問題？ 憑據是 100% 正確的，因為正如我所說，它在我的本地計算機上工作。 我的意思是，當我在我的電腦上運行時，Windows 10 它工作正常，當我運行另一台電腦時，Windows 2012 服務器不工作

Answer 1

盡管您在代碼中提供了憑據，但您並沒有在任何地方使用它。

它在您的本地計算機上工作，因為您可能安裝了 AWS CLI 並配置了憑據，並且代碼會使用該配置的憑據

下面的代碼將在代碼中使用內聯憑據，但是建議您使用部署到 AWS 的 EC2 實例配置文件設置的憑據或使用 CLI 配置的憑據

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")
