currentConditions 端点提供当前每小时空气质量信息。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 请求正文中添加请求选项。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：
基本请求示例
基本请求正文
以下代码展示了如何为 currentConditions 请求构建基本请求正文。在此示例中，您只需设置位置。
curl -X POST -d '{
"location": {
"latitude": 37.419734,
"longitude": -122.0827784
}
}' \
-H 'Content-Type: application/json' \
'https://airquality.googleapis.com/v1/currentConditions:lookup?key=YOUR_API_KEY'
基本请求响应
上述调用会生成以下 JSON 响应。如需详细了解响应数据，请参阅响应数据。
