json - HERE Maps API：如何搜索 100 多个地点
问题描述
这里的地图提供了一个 API 来搜索地图中的地点。如果没有提供阈值，默认情况下，它会返回一个包含 20 个结果的 json。然而，在 json 中，还提供了结果下一页的 url 。但是，尽管如此，我总共无法获得超过 100 个结果。
- q = 搜索关键字
- in = 地理坐标
- r = 区域半径

}我正在尝试提取整个区域中某家商店的所有特许经营权（大约 3000 家），但不知何故我无法获得超过 100 个结果。
有什么解决方案吗？
解决方案
Places API 是从最终用户客户的角度设计的，并且只为给定类别提供有限数量的结果。对于任何给定的类别，您仍然可以获得100 results(maximum). 您必须将 size 参数设置为size=100一次获得最大（100）个结果。
