每小时天气预报请求简介
如需请求每小时预报信息，请向以下网址发送 HTTP GET 请求：
https://weather.googleapis.com/v1/forecast/hours:lookup?key=YOUR_API_KEY&location.latitude=LATITUDE&location.longitude=LONGITUDE
在请求网址参数中添加相应位置的纬度和经度坐标。
每小时天气预报请求示例
默认情况下，forecast.hours 端点会返回 240 小时的数据（从当前小时开始）。您可以使用 hours 参数将请求范围限定为特定时间段。
以下示例请求加利福尼亚州山景城未来 3 小时的每小时预报信息：
curl -X GET "https://weather.googleapis.com/v1/forecast/hours:lookup?key=YOUR_API_KEY&location.latitude=37.4220 &location.longitude=-122.0841 &hours=3"
在响应中，interval 对象表示每个小时的信息：
