预测端点会提供最多 5 天的每日花粉信息。您可以控制向用户显示的以下信息：
- 预测天数
- 翻译字段的语言代码
- 响应页面大小
- 有关特定区域植物及其潜在过敏反应的详细信息
预测请求简介
如需使用预测端点请求每日花粉信息，请将 HTTP GET 请求发送到：
https://pollen.googleapis.com/v1/forecast:lookup?key=YOUR_API_KEY
在网址中添加参数。该请求包含您要获取花粉预报的地点、预报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地区代码以及所请求日期的每日天气预报信息。如果您请求超过一天的信息，响应正文还会包含一个令牌，用于在信息不符合所请求的页面大小时检索下一页。
响应正文还包含三个对象：
DayInfo 提供所代表的天气预报的日期，以及 PollenTypeInfo 和 PlantInfo。
PollenTypeInfo 可提供可用花粉类型（
GRASS、TREE和WEED）、花粉指数和相关健康建议（位于请求的坐标处）的季节性变化。PlantInfo 根据所请求的坐标提供植物名称和说明，包括季节性变化、外观和交叉反应。
