使用Ruby获取AWS区域名称(Get AWS region names with Ruby)

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，例如“us-east-1”等。

如果有人已经创建了gem来获取它们，我想使用它。有谁知道这样的宝石或有用的API？

I am developing a Rails application for AWS and would like to create drop down menu for region names, like "us-east-1" etc.

If someone already created gem to get them, I want to use it. Does anyone know such a gem or useful API?

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DescribeRegions调用的客户端界面：

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" }

您可以在此处查看gem文档： http ： //docs.amazonwebservices.com/AWSRubySDK/latest/frames.html

The AWS SDK for Ruby (aws-sdk gem) supports enumerating region names:

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"]

You can also use a client interface to the DescribeRegions call:

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" }
