我创建了这两个类来下载附近的地方并获取有关它们的详细信息（如姓名，距离，类型等）。

我唯一的问题是我无法下载网站和价格水平的地方，所以查看谷歌地方的文档，我发现我的问题是由于searhAPI（https://developers.google.com/places/web-service/search）不会检索这些信息关于地方，所以我必须使用https://developers.google.com/places/web-service/details获取地方的网站和价格水平，但我需要帮助，因为我不知道该怎么做或我如何修改我的课程，以使所有这些工作和能够我的Class QPlace也获得了地方的网站和价格水平。
