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.",

我有什么方法可以仅标题和描述？我认为它可以提高我的Web应用程序的性能。

我看过partial response，但它似乎无法奏效。

我上午在URL查询参数中包含我的API密钥。

谢谢

Answer 1

我根据部分回复文档添加了参数。

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. 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."
   }
  }
 ]
}

Answer 2

maxResults

将此内容包括在您的查询中。 5只是一个整数。＆maxResults = 5

Google会通过名为try it的网站API来帮助您创建API。 https://developers.google.com/books/docs/v1/reference/volumes/list?apix=true#try-it

Answer 3

也许响应为时已晚，但是您需要在访问API之前先激活它。当您尝试访问它时，说要使用某些项目ID从控制台激活它。只需复制该网址，即可直接进入仪表板，在这里您可以找到激活按钮发布，可以访问具有所需属性的部分响应。
