适用于 AWS 的开发工具包是否适用于 Ruby

Question

我正在 docker 容器内的 ruby on rails 应用程序中设置一个 Web 客户端，我希望它使用 Amazon Personalize SDK。该文档是为 Python 和 AWS CLI 编写的。我正在使用 Net：：HTTP 库用 ruby 编写一个示例请求并遇到了问题。

目前我的请求返回 403 和 <InvalidSignatureException> <Message>Credential should be scoped to correct service: 'personalize'. </Message> 错误。我认为我的问题是我没有使用正确的host

但是，当我捆绑aws-sdk宝石时，我看到许多aws-sdk宝石被捆绑在一起，看起来像aws-sdk-#{name_of_aws_service}，但没有aws-sdk-personalize。所以我的问题是，这是为什么？我试图用 Ruby 做这件事是不是吠错了树？我需要学习Python吗？

host = # removed because SO
service = 'es'
region = '' #removed because SO
signer = Aws::Sigv4::Signer.new(
  service: service,
  region: region,
  access_key_id: ENV['AWS_ACCESS_KEY_ID'],
  secret_access_key: ENV['AWS_SECRET_ACCESS_KEY']
)
document = {
  # removed because SO
}
signature = signer.sign_request(
  http_method: 'PUT',
  url: host,
  body: document.to_json
)
uri = URI(host)
Net::HTTP.start(uri.host, uri.port, :use_ssl => true) do |http|
  request = Net::HTTP::Put.new uri
  request.body = document.to_json
  request['Host'] = signature.headers['host']
  request['X-Amz-Date'] = signature.headers['x-amz-date']
  request['X-Amz-Security-Token'] = signature.headers['x-amz-security-token']
  request['X-Amz-Content-Sha256']= signature.headers['x-amz-content-sha256']
  request['Authorization'] = signature.headers['authorization']
  request['Content-Type'] = 'application/json'
  response = http.request request
  puts response.code
  puts response.body
end

Answer 1

我仔细阅读文档得到的答案是否定的。无论如何，AWS Personalize 都不适用于常规版本。所以我要把它标记为已解决并继续前进。

Answer 2

另一种解决方案是使用此 gem，假设您有密钥 ID、密钥和会话令牌

https://github.com/winebarrel/faraday_middleware-aws-sigv4

conn = Faraday.new(url: API_BASE_URL) do |faraday|
    faraday.request :aws_signers_v4,
         credentials: Aws::Credentials.new(response["access_key_id"], response["secret_key"], response["session_token"]),
          service_name: 'execute-api',
          region: 'us-east-1'
  faraday.adapter Faraday.default_adapter
end
puts conn.headers
response = conn.post('/orders') do |req|
    req.headers['Content-Type'] = 'application/json'
end
puts response.body
