Foursquare 有几个如何使用他们的 API 的示例,其中一个主要的示例我无法让它工作。但我的主要问题是如何在附近热门地点的地图上提取和显示列表而不是点?

https://developer.foursquare.com/overview/tutorial

我对此很陌生,不知道要使用什么方法或语言(json、jquery 等)。

任何人有任何方向或帮助让我开始如何从我可以通过 Foursquare 创建的 URL 中提取和列出数据,https://developer.foursquare.com/docs/venues/trending

这是他们用来在地图上调用和标记的代码,但我更喜欢一个列表:

场地/趋势 API 调用返回 JSON 格式的趋势场地数据。您可以访问https://developer.foursquare.com/docs/explore#req=venues/trending%3Fll%3D40.7,-74查看 API 返回的数据。您可以使用 Javascript(或其他语言)来操作 JSON 以获取热门场所列表。
