aws-sdk-ruby を v1 から v2 にアップグレードする

More than 3 years have passed since last update.

本家

https://github.com/aws/aws-sdk-ruby/blob/master/MIGRATING.md

に書いています。

が、

結構書いていないことが多かったので、書いておきます。
SQSとS3にフォーカスします。

本家にも書いていること

s3 = AWS::S3::Client.new # version 1
s3 = Aws::S3::Client.new # version 2

# version 1
s3 = AWS::S3.new

# version 2
s3 = Aws::S3::Resource.new

# version 1
s3.buckets['bucket-name'].objects['key'].delete

# version 2
s3.bucket('bucket-name').object('key').delete

設定系も変わっています。

# version 1
AWS.config({
  access_key_id: 'xxxxx',
  secret_access_key: 'xxxxxxx',
  region: 'ap-northeast-1'
})

# version 2
# config は hash になった
Aws.config.update({
  access_key_id: 'xxxxx',
  secret_access_key: 'xxxxxxx',
  region: 'ap-northeast-1'
})

書いていないこと(S3)

#--------------------------
# version 1
#--------------------------
bucket = AWS::S3.new.buckets['bucket-name']

s3object = bucket.objects['key']

# download
File.open('output', 'wb') do |f|
  s3object.read do |chunk|
    f.write(chunk)
  end
end

# data
data = s3object.read

# url
p bucket.url # "https://bucket-name.s3-ap-northeast-1.amazonaws.com"

# prefix 指定の一括削除
bucket.objects.with_prefix("prefix").delete_all

#--------------------------
# version 2
#--------------------------
bucket = Aws::S3::Resource.new.bucket('bucket-name') # Resouce ついて、bucket は単数形、[] => ()

s3object = bucket.object('key') # object は単数形、[] => ()

# download
File.open('output', 'wb') do |f|
  s3object.get do |chunk|
    f.write(chunk)
  end
end

# data
data = s3object.get.body.read

# url
p bucket.url # "http://bucket-name.s3.amazonaws.com/" 末尾にslashがつく

# prefix 指定の一括削除
bucket.objects({prefix: "prefix"}).batch_delete!

書いていないこと(SQS)

#--------------------------
# version 1
#--------------------------
sqs_queue = AWS::SQS.new.queues.named('queue_name')
sqs_queue.poll do |msg|
  # polling
  p msg.id
end


#--------------------------
# version 2
#--------------------------
client = Aws::SQS::Client.new
result = client.get_queue_url({ queue_name: 'queue_name' })
poller = Aws::SQS::QueuePoller.new(result.queue_url)

poller.poll do |msg|
  # polling
  p msg.message_id
end

もっといいやりかたがあるのかも。
