必要に応じて、コンテンツの保存と分類を行います。
currentConditions エンドポイントは、特定の場所の現在の気象状況に関する情報を提供します。API は次の値を返します。
- 現在の天気の説明と対応するアイコン
- 現在の気温
- 体感温度
- 露点温度
- 暑さ指数
- 風冷指数
- 相対湿度
- UV 指数
- 降水確率、降水量の割合、降水の種類
- 雷雨の確率
- 海面気圧
- 風の向き、風速、突風
- 視程と雲量
- 過去 24 時間の気温の変化、最高気温と最低気温、降水量などの履歴データ
API Explorer を使用すると、ライブ リクエストを行って、API と API オプションを理解できます。
現在の状況のリクエストについて
現在の状況をリクエストするには、次の URL に HTTP GET リクエストを送信します。
https://weather.googleapis.com/v1/currentConditions:lookup?key=YOUR_API_KEY&location.latitude=LATITUDE&location.longitude=LONGITUDE
リクエスト URL のパラメータに、位置情報の緯度と経度の座標を含めます。
現在の状況のリクエストの例
次の例は、カリフォルニア州マウンテンビューの現在の状況に関する情報をリクエストしています。
curl -X GET "https://weather.googleapis.com/v1/currentConditions:lookup?key=YOUR_API_KEY&location.latitude=37.4220&location.longitude=-122.0841"

単位系を指定する
デフォルトでは、Weather API はメートル法の単位でデータを返します。ヤード・ポンド法を使用して天気データをリクエストするには、リクエストで unitsSystem
パラメータを指定します。
次の例では、カリフォルニア州マウンテンビューの天気データをヤード・ポンド法でリクエストしています。
