在AWS S3中,有一个名为my-bucket
,使用AWS Ruby SDK ,可以通过ruby代码列出my-bucket
下的所有项目:
require 'aws-sdk'
s3 = Aws::S3::Resource.new(region: 'us-west-2')
bucket = s3.bucket('my-bucket')
# Show only the first 50 items
bucket.objects.limit(50).each do |item|
puts "Name: #{item.key}"
puts "URL: #{item.presigned_url(:get)}"
end
这可以。 但是在my-bucket
我在S3中有以下文件结构:
my-bucket/
customers/
products/
- data1.txt
- data2.txt
...
我的问题是:
Q1。 使用AWS Ruby SDK ,如何列出my-bucket/customers/products/
下的所有项目?
Q2。 如何检查例如my-bucket/customers/products/data3.txt
存在?
In AWS S3, I have a bucket named my-bucket
, with AWS Ruby SDK, I can list all the items under my-bucket
by ruby code:
require 'aws-sdk'
s3 = Aws::S3::Resource.new(region: 'us-west-2')
bucket = s3.bucket('my-bucket')
# Show only the first 50 items
bucket.objects.limit(50).each do |item|
puts "Name: #{item.key}"
puts "URL: #{item.presigned_url(:get)}"
end
This is fine. But under my-bucket
I have the following file structure in S3:
my-bucket/
customers/
products/
- data1.txt
- data2.txt
...
My questions are:
Q1. With AWS Ruby SDK, how can I list all the items under my-bucket/customers/products/
?
Q2. How can I check e.g. my-bucket/customers/products/data3.txt
exists?
