Google Books API 限制结果

Question

有没有办法限制 Google Books API 返回的结果？

例如以下网址：

https://www.googleapis.com/books/v1/volumes?q=isbn:0751538310

返回以下内容：

He arrives to find her brutally murdered body on the kitchen floor and a hitman lying in wait for him. It is then he realises his whole life has been a lie. His parents are not who he thought they were, his girlfriend is not who he thought she was, his entire existence an ingeniously constructed sham. And now that he knows it, he is in terrible danger. So he is catapulted into a violent world of mercenaries, spies and terrorists. Pursued by a ruthless band of killers who will stop at nothing to keep old secrets buried, Evan's only hope for survival is to discover the truth behind his past. An absolute page-turner, Panic has been acclaimed as one of the most exciting thrillers of recent years.",

有没有什么办法可以返回只在标题和描述？我认为它可以提高我的 Web 应用程序的性能。

我查看了部分响应，但似乎不起作用。

我感到，包括URL中的查询参数我的API密钥。

谢谢

我根据部分响应文档添加了参数。

请参阅以下链接中的参数：

https://www.googleapis.com/books/v1/volumes?q=isbn:0751538310&fields=items(volumeInfo/description,volumeInfo/title)

它将返回：

{
 "items": [
  {
   "volumeInfo": {
    "title": "Panic",
    "description": "Things are going well for young film-maker Evan Casher - until he receives an urgent phonecall from his mother, summoning him home.
