预测端点每天最多提供 5 天的花粉信息。您可以控制向用户显示的以下信息：
- 预测天数
- 已翻译字段的语言代码
- 响应页面大小
- 有关指定区域的植物及其过敏性潜在危害的详细信息
关于预测请求
如需使用预测端点请求每日花粉信息，请向以下 URI 发送 HTTP GET 请求：
https://pollen.googleapis.com/v1/forecast:lookup?key=YOUR_API_KEY
在网址中添加您的参数。请求包含您要获取花粉量预测的位置、预测天数以及要在响应中包含的花粉信息。
预测响应简介
响应正文会提供所请求坐标的区域代码和所请求日期的每日预报信息。如果您请求信息不止一天，响应正文中还会包含一个令牌，当信息不适合所请求的页面大小时，可用于检索下一页。
响应正文还包含三个对象：
DayInfo 提供代表的预测的日期，以及 PollenTypeInfo 和 PlantInfo。
PollenTypeInfo 根据请求坐标提供可用花粉类型（
GRASS、TREE和WEED）的季节性、花粉指数以及相关的健康建议。PlantInfo 会在请求的坐标上提供植物名称和说明，包括季节性、外观和交叉反应。
