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: orientdb_exec.rb
    path of file: ./repos/metasploit-framework/modules/exploits/multi/http
    
    the code of the file until where you have to start completion: ##
# This module requires Metasploit: https://metasploit.com/download
# Current source: h
    
  def execute_command(cmd, opts = {})
    vprint_status("Attempting to execute: #{cmd}")
    @uri = target_uri
    @uri.path = normalize_uri(@uri.path)
    res = send_request_raw({'uri' => "#{@uri.path}listDatabases"})
    if res && res.code == 200 && res.body.length > 0
      begin
        json_body = JSON.parse(res.body)["databases"]
      rescue JSON::ParserError
        print_error("Unable to parse JSON")
        return
      end
