目前氣象

currentConditions 端點會提供目前每小時的空氣品質資訊。您可以控制系統傳回哪些空氣品質指標和相關資訊 (例如污染物濃度和健康建議)。

您可以使用 currentConditions 端點，透過 HTTP POST 要求傳送目前每小時的空氣品質，方法是傳送 HTTP POST 要求至：

https://airquality.googleapis.com/v1/currentConditions:lookup?key=YOUR_API_KEY

在 JSON 要求內文中加入要求選項。要求主體包含您想取得空氣品質目前狀況的位置，以及各種選項，用於控制回應中包含的空氣品質資訊。

您可以透過 APIs Explorer 提出即時要求，熟悉 API 和 API 選項：

基本要求範例

基本要求主體

以下程式碼說明如何為 currentConditions 要求建構基本要求主體。在這個範例中，您只需設定位置。

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'
