currentConditions 端点提供当前每小时的空气质量信息。您可以控制系统返回哪些 AQI 和相关信息（例如污染物浓度水平和健康建议）。
您可以使用 currentConditions 端点请求当前每小时空气质量，方法是向以下网址发送 HTTP POST 请求：
https://airquality.googleapis.com/v1/currentConditions:lookup?key=YOUR_API_KEY
在 JSON 请求正文中包含您的请求选项。请求正文包含您想要获取空气质量当前状况的位置，以及用于控制响应中包含哪些空气质量信息的各种选项。
借助 API Explorer，您可以发出实时请求，以便熟悉 API 和 API 选项：
