使用Ruby获取AWS区域名称

我正在为AWS开发Rails应用程序，并希望为区域名称创建下拉菜单，如“us-east-1”等

如果有人已经创建了gem来获取它们，我想使用它。有人知道这样一个gem或有用的API吗？

在我的例子中，我可以做到：

>> `ec2-describe-regions`.scan(/REGION\s+(\S+)/).flatten
=> ["eu-west-1", "sa-east-1", "us-east-1", "ap-northeast-1", "us-west-2", "us-west-1", "ap-southeast-1"]

我找到宝石了

AWS SDK for Ruby（AWS SDK gem）支持枚举区域名称：

require 'aws-sdk'

ec2 = AWS::EC2.new(:access_key_id => '...', :secret_access_key => '...')
ec2.regions.map(&:name)
=> ["eu-west-1", "sa-east-1", "us-east-1", "ap-northeast-1", "us-west-2", "us-west-1", "ap-southeast-1"] 

您还可以使用客户端接口来调用DescribeRegions：

ec2.client.describe_regions
=> { :region_info=>[
    {:region_name=>"eu-west-1", :region_endpoint=>"ec2.eu-west-1.amazonaws.com"}, 
    {:region_name=>"sa-east-1", :region_endpoint=>"ec2.sa-east-1.amazonaws.com"}, 
    {:region_name=>"us-east-1", :region_endpoint=>"ec2.us-east-1.amazonaws.com"}, 
    {:region_name=>"ap-northeast-1", :region_endpoint=>"ec2.ap-northeast-1.amazonaws.com"}, 
    {:region_name=>"us-west-2", :region_endpoint=>"ec2.us-west-2.amazonaws.com"}, 
    {:region_name=>"us-west-1", :region_endpoint=>"ec2.us-west-1.amazonaws.com"}, 
    {:region_name=>"ap-southeast-1", :region_endpoint=>"ec2.ap-southeast-1.amazonaws.com"}
  ], 
  :request_id=>"04458cac-bdf2-4847-bf1f-c7ea65813777"
}
