Google 书籍 API 限制结果

Question

有什么方法可以限制 return 由 Google 书籍 API 编辑的结果吗？

例如下面的URL:

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

Returns 以下:

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.",

有什么办法可以return只标题和描述？我认为它可以提高我的网络应用程序的性能。

我查看了 partial response 但它似乎不起作用。

我 am 在 URL 查询参数中包含我的 API 键。

谢谢

Answer 1

我根据部分响应文档添加了参数。

查看下面的参数link:

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

它将 return:

{
 "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.

可能来不及回复，但您需要先激活 API 才能访问它。当您尝试访问它时，它说要使用某个项目 ID 从控制台激活它。只需复制 url 即可直接进入仪表板，您可以在其中找到激活按钮 post，您可以通过该按钮访问具有所需属性的部分响应。

最大结果

将其包含在您的查询中。 5只是一个整数。 &maxResults=5

Google 将帮助您使用这个网站 API 创建您的 API 试试看。 https://developers.google.com/books/docs/v1/reference/volumes/list?apix=true#try-it
