示例

本部分介绍了向 Places Insights API 发出的一系列示例请求。

返回圆形内的位置

返回伦敦特拉法加广场方圆 200 米范围内的所有餐厅。

  • 搜索区域是一个以特定纬度和经度为中心的圆形。此圆形的半径为 200 米，这决定了搜索区域的大小。
  • 请求的地点类型为餐厅，此值会使用 typeFilters 中的 includedTypes 传递。
  • 系统使用 INSIGHTS_COUNT 请求计数，并使用 INSIGHTS_PLACES 请求地点 ID。

排除地点类型

您可以从统计范围中排除地点类型。

以下请求与第一个示例相同，但会向 typeFilters 添加 excludedTypes。您可以为 includedTypes 和 excludedTypes 使用字符串或字符串数组。

在此示例中，系统会从 restaurant 计数中排除两种地点类型：cafe 和 bakery。

自定义多边形

此示例演示了如何使用自定义多边形来定义搜索区域。请注意，指定 INSIGHTS_PLACES 会将搜索范围限制在足够小且最多可返回 100 个地点 ID 的区域。对于较大的区域，请使用 INSIGHTS_COUNT 来绕过此限制，以便该服务无需返回各个地点 ID。

与之前一样，使用的地点类型为 restaurant。此示例还介绍了另外三种过滤器：

  • operatingStatus：此示例仅统计运营中的位置。
  • priceLevel：此示例仅统计价格低廉和价格适中的地点。
  • ratingFilter：此示例仅统计评分介于 4.0 到 5.0 之间的地点。

地理区域

此示例使用地理区域地点 ID 设置搜索区域。这些地点 ID 包含地点（例如镇或城市）的几何图形。此处使用的地点 ID 为 ChIJiQHsW0m3j4ARm69rRkrUF3w，对应于加利福尼亚州山景城。

将地点 ID 传递给 Places Insights API 会将搜索区域设置为相应地理区域的边界。地点 ID 使用 place 传递，格式为 places/place_ID。

您可以通过以下任一方式获取地理区域地点 ID：
