forecast 端点
每小时提供长达 96 小时（4 天）的空气
指定地理位置的质量预报信息每份预报都包含每小时的空气质量指数以及其他信息：
- 预测的具体时间和日期或时间段
- 翻译字段的语言代码
- 本地或自定义空气质量指数 (AQI)
- 健康建议
- 主要污染物
- 污染物浓度
- 有关污染物的更多信息
- 响应页面大小
- 调色板
借助 API Explorer，您可以发出实时请求 API 和 API 选项：
预测请求简介
您可以使用预报端点请求每小时空气质量预报信息，方法是向以下网址发送 HTTP POST 请求：
https://airquality.googleapis.com/v1/forecast:lookup?key=YOUR_API_KEY
在请求正文中添加参数。请求正文包含您要处理的位置 比如获取每小时空气质量预报信息以及 控制要在响应中包含哪些其他信息。
预测响应简介
响应正文会提供用于显示空气质量预报信息、空气质量指数和其他自定义信息的世界协调时间 (UTC) 日期和时间。如果信息不符合请求的页面大小，响应正文还包含用于检索下一页的令牌。
基本请求示例
以下代码展示了如何构建预测请求。在此示例中 由您指定地点、日期和时间（从下一个小时到 96 小时），以显示每小时空气质量预报信息。
curl -X POST -d '{
