[Ruby] aws-sdk v3.0.1 で S3 にファイルアップロード

Posted at

本題

aws-sdk を使ってS3にファイルアップロードする。
version 3.0 を使っている日本語記事が見つからなかったので書く。

install

Gemfileに以下を追加
gem 'aws-sdk'
bundle install
$ bundle install

How To Use

require 'aws-sdk'
class Caws
  def initialize
    @bucket_name = 'bucketname'

    Aws.config.update({
        region: 'ap-northeast-1',
        credentials: Aws::Credentials.new('ACCESS-KEY', 'SECRET-KEY')
    })

    s3 = Aws::S3::Resource.new
    @bucket = s3.bucket(@bucket_name)
  end

  def send(s3_path,upd_path,file_name)
    o = @bucket.object(s3_path + '/' + file_name)
    o.upload_file(upd_path + '/' + file_name)
  end
end

ACCESS-KEY とか SECRET-KEY はここで取得できた。

How to use send

  • s3_path : s3 の指定したbucket上のpath
  • upd_path : ローカルにあるファイルパス
  • file_name : ファイルネーム

Test

class CawsTest < Test::Unit::TestCase

  def setup
    @aws = Caws.new
  end

  def test_upd
    @aws.send("s3/file/path","/local/file/path", "file.txt")
  end
end
