获取当前天气状况

currentConditions 端点提供有关特定地点的当前天气状况的信息。API 会返回以下内容：

  • 对当前天气状况的说明，并附带相应的图标
  • 当前温度
  • 体感温度
  • 露点
  • 暑热指数
  • 风寒温度
  • 相对湿度传感器
  • 紫外线指数
  • 降水概率、百分比和类型
  • 雷暴概率
  • 海平面气压
  • 风向、风速和阵风
  • 能见度和云覆盖率
  • 过去 24 小时的历史数据，包括温度变化、最高温度和最低温度以及降水量

借助 API Explorer，您可以发出实时请求，以便熟悉 API 和 API 选项：

实时天气请求简介

如需请求当前天气状况，请向以下网址发送 HTTP GET 请求：

https://weather.googleapis.com/v1/currentConditions:lookup?key=YOUR_API_KEY&location.latitude=LATITUDE&location.longitude=LONGITUDE

在请求网址的参数中添加相应位置的纬度和经度坐标。

当前天气状况请求示例

以下示例请求加利福尼亚州山景城的当前天气状况信息：

curl -X GET "https://weather.googleapis.com/v1/currentConditions:lookup?key=YOUR_API_KEY&location.latitude=37.4220&location.longitude=-122.0841"

响应的格式如下：

指定单位制

默认情况下，Weather API 会以公制单位返回数据。如需使用英制单位请求天气数据，请在请求中指定 unitsSystem 参数。

以下示例请求以英制单位表示的加利福尼亚州山景城的天气数据：

curl -X GET "https://weather.googleapis.com/v1/currentConditions:lookup?key=YOUR_API_KEY&location.latitude=37.4220&location.longitude=-122.0841&unitsSystem=IMPERIAL"
