如何按修改日期列出Amazon S3存储桶内容? [英] How list Amazon S3 bucket contents by modified date?
问题描述
在大多数情况下，由于我们很难在其中存储数据，因此我们将文件加载到一个普通的S3存储桶中.
Most of the time it happens that we load files in a common S3 bucket due to which it becomes hard to figure out data in it.
如何查看在特定日期上传的对象?
How can I view objects uploaded on a particular date?
推荐答案
一种解决方案可能是使用 s3api .如果您的对象少于1000个，那么它很容易工作，否则您需要进行分页.
One solution would probably to use the s3api. It works easily if you have less than 1000 objects, otherwise you need to work with pagination.
s3api可以列出所有对象，并且具有s3中导入的键的lastmodified属性的属性.然后可以对它进行排序，查找日期之后或之前的文件，匹配日期...
s3api can list all objects and has a property for the lastmodified attribute of keys imported in s3. It can then be sorted, find files after or before a date, matching a date ...
运行该选项的示例
-
给定日期的所有文件
all files for a given date
DATE=$(date +%Y-%m-%d)
aws s3api list-objects-v2 --bucket test-bucket-fh --query 'Contents[?contains(LastModified, `$DATE`)]'
特定日期之后的所有文件
all files after a certain date
export YESTERDAY=`date -v-1w +%F`
aws s3api list-objects-v2 --bucket test-bucket-fh --query 'Contents[?LastModified > `$YESTERDAY`]'
s3api将返回少量元数据，因此您可以过滤特定元素
s3api will return a few metadata so you can filter for specific elements
DATE=$(date +%Y-%m-%d)
aws s3api list-objects-v2 --bucket test-bucket-fh --query 'Contents[?contains(LastModified, `$DATE`)].Key'
