boto3 s3 copy_object 与 ContentEncoding 参数

Question

I'm trying to copy s3 object with boto3 command like below我正在尝试使用如下所示的 boto3 命令复制 s3 对象

import boto3 
client = boto3.client('s3')
client.copy_object(Bucket=bucket_name, ContentEncoding='gzip', CopySource=copy_source, Key=new_key)

To copy the object succeeded, but ContentEncoding metadata was not added to the object.复制对象成功，但ContentEncoding元数据未添加到对象。

When I use the console to add Content-Encoding metadata, there was no problem.当我使用控制台添加 Content-Encoding 元数据时，没有问题。

But using python boto3 copy command, it cannot do that.但是使用 python boto3 copy 命令，它不能这样做。

Here's a document link about client.copy_object()这是关于client.copy_object()的文档链接

And the application versions are like this.应用程序版本是这样的。

python=2.7.16蟒蛇=2.7.16

boto3=1.0.28 boto3=1.0.28

botocore=1.13.50 botocore=1.13.50

Thank you in advance.先感谢您。

尝试将 MetadataDirective='REPLACE' 添加到您的 copy_object 调用

client.copy_object(Bucket=bucket_name, ContentEncoding='gzip', CopySource=copy_source, Key=new_key, MetadataDirective='REPLACE')
