Question

我正在使用“按类别浏览热门地点” API，并且对于结果中的所有项目，它始终返回averageRating为0。

我使用各种类别（例如餐馆和景点博物馆）进行了此调用，但对于averageRating而言，它始终返回0。这里没有提供此详细信息吗？如果是，为什么在响应中返回它？

一些细节：

我正在拨打此网址：

https://places.ls.hereapi.com/places/v1/discover/explore?at=52.5159%2C13.3777&cat=sights-museums&apiKey={api_key}

，它返回如下内容：

这里不提供饭店或景点博物馆的平均价格吗？

Answer 1

在文档中，如果该地点未获得评分，则显示为0

注意：如果该地点（尚未）未评级，则平均值和计数值均为零。但是，如果无法对地点（例如街道）进行评级，则不会显示整个评级对象。

为什么averageRating始终为0？
