python - 调用CopyObject操作时NoSuchBucket

Question

我尝试从 s3 中的旧文件恢复文件，前提是该文件不存在。我当前的代码是这样的:

import botocore
import os

s3 = boto3.resource('s3')

def checkFile(filename, buckett="selfmarkett"):
    try:
        s3.Object(buckett, filename).load()
    except botocore.exceptions.ClientError as e:
        if e.response['Error']['Code'] == "404":
            try:
                _filename, _extension = os.path.splitext(filename)
                oldFilename = _filename + ".p_up" + _extension
                s3.Object(buckett, filename).copy_from(CopySource=oldFilename)
            except Exception as error:
                print("Error2:", error)

我的问题是，当脚本尝试使用函数 copy_from 时，返回此错误:

NoSuchBucket: An error occurred (NoSuchBucket) when calling the CopyObject operation: The specified bucket does not exist

存储桶已在对象中指定，我该如何修复此错误？

我遇到了同样的问题，我通过在 CopySource 的路径中添加存储桶名称来修复它，如下所示:

s3.Object(bucket, "new_folder/new_file").copy_from(CopySource="<bucket>/old_folder/old_file")
