You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: dbconnectionpool.rb
    path of file: ./repos/metasploit-framework/lib/msf/core/exploit/remote/http/nifi
    
    the code of the file until where you have to start completion: # -*- coding: binary -*-

module Msf::Exploit::Remote::HTTP::Nifi::Dbconnectionpool
  include Msf::Exploit::Remote::HttpClient

  class 
    
  def stop_dbconnectionpool(token, db_con_pool)
    vprint_status("Attempting to stop DB Connection Pool: #{db_con_pool}")
    body = {
      'disconnectedNodeAcknowledged' => false,
      'state' => 'DISABLED',
      'uiOnly' => true,
      'revision' => {
        'clientId' => 'x',
        'version' => 0
      }
    }
    opts = {
      'method' => 'PUT',
      'uri' => normalize_uri(target_uri.path, 'nifi-api', 'controller-services', db_con_pool, 'run-status'),
      'ctype' => 'application/json',
      'data' => body.to_json
    }
    opts['headers'] = { 'Authorization' => "Bearer #{token}" } if token
    res = send_request_cgi(opts)
    raise DBConnectionPoolError if res.nil?

    unless res.code == 200
      print_bad("Unexpected response code: #{res.code}")
      raise DBConnectionPoolError
