问题描述

想知道下面的AWS CLI的python boto3代码

Would like to know the python boto3 code for below AWS CLI

aws s3api list-objects-v2 \
--bucket myBucket \
--prefix path1/path2 \
--query 'reverse(sort_by(Contents,&LastModified))[0]'

我没有看到list_objects_v2的任何查询选项

i didnt see any query option for list_objects_v2

推荐答案

--query 功能="nofollow noreferrer"> AWS命令行界面(CLI)是CLI本身的功能，而不是在API调用期间执行.

The --query capability in the AWS Command-Line Interface (CLI) is a feature of the CLI itself, rather than being performed during an API call.

如果您使用的是boto3 list_object_v2()命令，则返回完整的结果.

If you are using the boto3 list_object_v2() command, a full set of results is returned.

然后您可以使用Python操作结果.

您似乎想列出存储桶/路径中的最新对象，因此可以使用以下内容:

It appears that you are wanting to list the most recent object in the bucket/path, so you could use something like:

import boto3

client = boto3.client('s3',region_name='ap-southeast-2')

response = client.list_objects_v2(Bucket='my-bucket')

print (sorted(response['Contents'], key=lambda item: item['LastModified'])[-1])
