无法连接到OpenTok

Question

我创建了一个聊天室，像这样使用Opentok：

在room.rb模型中

 require 'opentok'

 def config_opentok
    @opentok ||= OpenTok::OpenTok.new Rails.application.secrets.open_tok_api_key, Rails.application.secrets.open_tok_secret
 end

  def set_opentok_params
    session = config_opentok.create_session
    self.session_id = session.session_id
    self.opentok_token = session.generate_token({
      expire_time: Time.now.to_i + 30.days
      })
  end

它工作得很好，但有时我会收到这样的错误：

OpenTok::OpenTokError: Failed to connect to OpenTok. Response code: execution expired

我怎么才能修复它？

谢谢。

Answer 1

def config_opentok
        tries = 3
        begin
          @opentok = OpenTok::OpenTok.new api_key, api_secret
          logger.debug "opentok connected."
         rescue Errno::ETIMEDOUT => e
          log.error e 
          tries -= 1
            if tries > 0
              logger.debug "retrying opentok.new..."
            retry 
            else
              logger.debug "opentok.new timed out..."
              puts "ERROR: #{e.message}" 
            end
          end
        end
