我正在嘗試編寫一個Flask應用程序以上傳到AWS S3存儲桶。當我在PyCharm中本地運行它時，它工作正常。但是，一旦我把它部署到AWS（部署在端口80上的瓶的應用程序），我現在得到一個錯誤......嘗試從Flask應用程序中的EC2實例將文件上傳到Amazon S3時出現ClientError（SignatureDoesNotMatch）
botocore.exceptions.ClientError: An error occurred (SignatureDoesNotMatch) when calling the ListBuckets operation: The request sture we calculated does not match the signature you provided. Check your key and signing method.
當鍵盤本地工作......但不要在AWS EC2實例工作。我的一些初步想法可能是端口問題或boto3問題。雖然我不確定，因爲它在本地工作，但不在AWS上。
任何幫助？這裏是我的代碼...與OFC
