forecast 端点最多可提供 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
- 已翻译字段的语言代码
- 响应页面大小
- 有关特定区域的植物及其过敏潜力的详细信息
借助 API Explorer，您可以发出实时请求，以便熟悉 API 和 API 选项：
预测请求简介
如需使用预报端点请求每日花粉信息，请向以下网址发送 HTTP GET 请求：
https://pollen.googleapis.com/v1/forecast:lookup?key=YOUR_API_KEY
在网址中添加参数。该请求包含您想要获取花粉预报的位置、预报天数以及要包含在响应中的花粉信息。
预测响应简介
响应正文会提供所请求坐标的区域代码，以及所请求的每一天的每日预报信息。如果您请求的信息超过一天，则响应正文还会包含一个令牌，以便在信息不符合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 提供所代表预报的日期，以及 PollenTypeInfo 和 PlantInfo。
PollenTypeInfo 提供请求坐标处可用花粉类型（
GRASS、TREE和WEED）的季节性变化、花粉指数以及相关健康建议。PlantInfo 会提供请求坐标处的植物名称和说明，包括季节性、外观和交叉反应。
