我找到了另一个解决方案
s3 = boto3.resource('s3')
s3.Object('my_bucket','new_file_key').copy_from(CopySource='my_bucket/old_file_key')
s3.Object('my_bucket','old_file_key').delete()

You cannot rename objects in S3, so as you indicated, you need to copy it to a new name and then deleted the old one:
您不能在 S3 中重命名对象，因此正如您所指出的，您需要将其复制到一个新名称，然后删除旧名称：
client.copy_object(Bucket="BucketName", CopySource="BucketName/OriginalName", Key="NewName")
client.delete_object(Bucket="BucketName", Key="OriginalName")

Following examples from updated Boto3 documentation for the copy()method, which also works with copy_object() and appears to be the required syntax now:
以下示例来自更新的 Boto3 文档中的copy()方法，该方法也适用于 copy_object() 并且现在似乎是必需的语法：
copy_source = {'Bucket': 'source__bucket', 'Key': 'my_folder/my_file'}
s3.copy_object(CopySource = copy_source, Bucket = 'dest_bucket', Key = 'new_folder/my_file')
s3.delete_object(Bucket = 'source_bucket', Key = 'my_folder/my_file')
Note from documentation linked above:
上面链接的文档中的注释：
CopySource (dict) -- The name of the source bucket, key name of the source object, and optional version ID of the source object. The dictionary format is: {'Bucket': 'bucket', 'Key': 'key', 'VersionId': 'id'}. Note that the VersionId key is optional and may be omitted.
CopySource (dict) -- 源桶的名称，源对象的键名，源对象的可选版本ID。字典格式为：{'Bucket': 'bucket', 'Key': 'key', 'VersionId': 'id'}。请注意，VersionId 键是可选的，可以省略。
