当前天气状况

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，方法是将 HTTP POST 请求发送到：

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 API 和 API 选项：

试试看！

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，您仅设置了位置。

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内容 JSON 响应。 如需详细了解响应数据，请参阅响应数据。

注意 ：默认情况下，响应中包含通用 AQI 和基本 AQI 信息。您可以通过设置相应的参数来移除 AQI 或将其替换为其他 AQI。
