你好开发者社区，

我正在使用 AWS Cloudsearch（API 版本：2011-02-01）并尝试从位于 heroku 上的应用程序上传和搜索，这意味着我需要一个具有静态 IP 的代理，以便我可以将其列入白名单，但我是有问题...

我正在使用一个名为 Proximo 的 Heroku 插件。这是 Heroku 使用 RestClient 设置它的代码示例：

require "rest-client"

RestClient.proxy = ENV["PROXIMO_URL"] if ENV["PROXIMO_URL"]

res = RestClient.get("http://api.someservice.com/endpoint")

puts "status code", res.code
puts "headers", res.headers

我正在使用使用法拉第发出请求的aws_cloud_search gem，并且我正在努力通过我的补丁从 CloudSearch 获得正确的响应

 # aws_cloud_search.rb

 def self.create_connection(url, aws_access_key_id=nil, aws_secret_access_key=nil)

    options = ENV['PROXIMO_URL'] ? { proxy: ENV['PROXIMO_URL'] } : {}

    connection = Faraday.new url, options do |builder|
      builder.use AWSCloudSearch::HttpCodeResponseMiddleware
      builder.use FaradayMiddleware::EncodeJson
      builder.use FaradayMiddleware::ParseJson
      builder.adapter Faraday.default_adapter  
      builder.proxy ENV['PROXIMO_URL'] if ENV['PROXIMO_URL']
    end
    connection.headers['User-Agent'] = "AWSCloudSearch-Ruby-Client/#{VERSION}"
    connection
  end

我尝试了许多在这里（以及其他地方）看到的补丁工作组合，但无济于事。当我使用 Proximo 提供的带有端口 80 的 IP 地址设置代理时（如他们所建议的那样），我得到以下信息：

Faraday::Error::ParsingError: 757: unexpected token at 'invalid'

=>"http://nn.nnn.nn.nn:80" (i've obscured my ip address)

我认为这意味着被解析的实际密钥是“无效的”，我在搜索和文档中得到了这个（我没有使用 ssl）。（我在没有代理的情况下获得带有 403 Forbidden 的 html）。我试图打印出响应正文，但我认为错误发生在我什至可以打印出来之前（与 403 一样）。

有什么明显的我没有尝试过的或者我的方法有问题吗？

谢谢

gem现在aws-sdk-core支持 CloudSearch 域 API（搜索、建议、上传文档）。您应该能够安装 gem 并使用代理配置客户端：

require 'aws-sdk-core'

client = Aws::CloudSearchDomain::Client.new(
  endpoint:'http://...',
  http_proxy: 'http://...')

可以在此处找到客户端 API 参考：http: //docs.aws.amazon.com/sdkforruby/api/Aws/CloudSearchDomain/Client.html
