目前氣象

currentConditions 端點 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

將要求選項納入 JSON 要求主體。 要求主體包含希望空氣的目標地點 空氣品質即時路況，以及控制空氣品質的各種選項 要在回應中加入的資訊

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'

基本要求回應

上述呼叫會產生下列 JSON 回應。如要進一步瞭解回應資料，請參閱「回應資料」。

注意：根據預設，回應會包含通用空氣品質指標 (AQI) 和基本空氣品質指標資訊。只要設定 對應的參數
