URL提取程序类的方法

Question

我正在用Javascript开发一个类，该类将获取作为参数传递给构造函数的URL的HTML。我有点坚持要实现的各种方法。寻找建议。

class HttpConnection extends EventEmitter {
  /* HttpConnectionManager class creates an object and passes an URL that needs to be fetched as a parameter to the constructor */
  constructor (url, userAgent) {
  }

  /* fetch URL, send HTTP request and return its HTML body. TBD the return format */
  fetchUrl () {
  }

  /* Update statistics based on the result returned bu the HTTP request, as well as logging an error if one occurs */
  updateStats () {
  }

  /* close the connection and return true if connection is now closed */
  cleanUp (request) {
  }
}
module.exports = HttpConnection

到目前为止，这些是已经实现的方法。 fetchUrl（）方法有点长，所以我在考虑将其分成几种方法。
