Question

Hello开发者社区，

我正在使用AWS Cloudsearch（API版本：2011-02-01）并尝试从生活在heroku上的应用程序上传和搜索，这意味着我需要一个带有静态IP的代理，以便我可以将其列入白名单，但是我遇到了问题...

我正在使用名为Proximo的Heroku插件。这是Heroku使用RestClient进行设置的代码示例：

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Faraday发出请求的aws_cloud_search gem，并且我很难通过我的补丁从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

我尝试了许多补丁工作的组合here（以及其他地方）无济于事。当我使用端口80（正如他们建议的那样）设置具有Proximo提供的IP地址的代理时，我得到以下内容：

我认为这意味着被解析的实际密钥是'无效'，我在搜索和文档上得到这个（我不使用ssl）。（我在没有代理的情况下获得带有403 Forbidden的html）。我试图打印出响应体，但我认为错误发生在我甚至可以将其打印出来之前（与403一样）。

我没有尝试过任何明显的问题或者我的方法有问题吗？

aws-sdk-core gem现在支持CloudSearch域API（Search，Suggest，UploadDocuments）。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://...')

客户端API参考可以在这里找到： http://docs.aws.amazon.com/sdkforruby/api/Aws/CloudSearchDomain/Client.html

在代理后面发出请求时解析错误
