AWS SNS Ruby SDK无法将端点订阅到应用程序

Question

Ruby SDK有点令人困惑，因为文档有两种订阅方法。现在我不相信其中一个here。

另一种是源代码中所说的预期方法： # To create a subscription, use the {Topic#subscribe} method. 但是在它指向的代码中，传入的选项会经过一个过滤过程，不允许我指定application协议。

def endpoint_opts（endpoint，opts = {}）

    case
    when endpoint.is_a?(SQS::Queue)

      # auto add a policy to the queue to allow the topic
      # to send the queue messages
      unless opts[:update_policy] == false
        policy = endpoint.policy || SQS::Policy.new
        policy.allow(
          :principal => :any,
          :actions => [:send_message],
          :resources => [endpoint]
        ).where(:source_arn).is(arn)
        endpoint.policy = policy
      end

      { :protocol => 'sqs', :endpoint => endpoint.arn }

    when endpoint =~ /^arn:/

      ################################################# 
      THIS IS WHAT FILTERS IT, I get this error
      ################################################# 
      raise ArgumentError, "expected a queue ARN" unless
        endpoint =~ /^arn:aws(.*?):sqs:/
      { :protocol => "sqs", :endpoint => endpoint }
    when endpoint.kind_of?(URI)
      { :protocol => endpoint.scheme,
        :endpoint => endpoint.to_s }
    when endpoint =~ /^(https?):/
      { :protocol => $1, :endpoint => endpoint }
    when endpoint.include?("@")
      { :protocol => opts[:json] ? "email-json" : "email",
        :endpoint => endpoint }
    when endpoint.gsub(/\D/,'') =~ /\d{11,15}/
      { :protocol => "sms", :endpoint => endpoint.gsub(/\D/,'') }
    else
      raise ArgumentError, "could not determine protocol for '#{endpoint}'"
    end
  end

and the documentation also doesn't list a way to do it, as it lists all protocols other than through an application.

所以...看起来application协议选项是故意过滤的，或者某人没有写出非常好的测试:) 有没有办法使用AWS SDK订阅从应用程序到主题的端点？我在这里错过了一些大事吗？请帮忙！
