产品概念

使用我们的 OpenWeather One Call API 3.0可以轻松获取基本天气数据、短期和长期预报以及汇总天气数据。该产品旨在确保轻松从 Dark Sky API 迁移。

One Call API 3.0 包含 4 个端点并提供对各种数据的访问：

当前天气和预报：
- 1 小时的分钟预报
- 48 小时每小时预报
- 8 天每日预报
以及政府天气警报
任何时间戳的天气数据，45 年历史存档和未来 4 天的预报
每日汇总45 年的天气数据存档和 1.5 年后的预报
利用 OpenWeather AI 技术，提供今天和明天天气预报的人性化天气概览

One Call API 3.0 基于专有的OpenWeather 模型，每 10 分钟更新一次。因此，为了接收最准确、最新的天气数据，我们建议您每 10 分钟请求一次 One Call API 3.0。

请注意，One Call API 3.0仅包含在“One Call by Call”订阅中。此单独订阅包括每天 1,000 次免费呼叫，并且您只需为对此产品进行的 API 调用次数付费。请注意，您无需订阅任何其他 OpenWeather 订阅计划即可访问 One Call API 3.0。请在定价页面和常见问题解答中查找更多详细信息。

如何开始

如果您还没有获得OpenWeather API 密钥，请注册OpenWeather 服务。
关注定价页面来了解价格详情。

One Call API 3.0 仅包含在单独订阅中，您只需为对此产品进行的 API 调用次数付费。请在定价页面上查找更多详细信息。

如何进行 API 调用

API 调用

https://api.openweathermap.org/data/3.0/onecall?lat={lat}&lon={lon}&exclude={part}&appid={API key}

参数
`lat`	必需的	纬度，十进制（-90；90）。如果您需要地理编码器自动将城市名称和邮政编码转换为地理坐标，反之亦然，请使用我们的地理编码 API
`lon`	必需的	经度，十进制（-180；180）。如果您需要地理编码器自动将城市名称和邮政编码转换为地理坐标，反之亦然，请使用我们的地理编码 API
`appid`	必需的	您的唯一 API 密钥（您始终可以在帐户页面的“API 密钥”选项卡下找到它）
`exclude`	选修的	通过使用此参数，您可以从 API 响应中排除部分天气数据。它应该是逗号分隔的列表（不带空格）。可用值： `current` `minutely` `hourly` `daily` `alerts`
`units`	选修的	测量单位。`standard`和`metric`单位`imperial` 可用。如果不使用`units`参数， `standard`将默认应用单位。了解详情
`lang`	选修的	您可以使用`lang`参数来获取您语言的输出。了解更多

API 调用示例

在进行 API 调用之前，请注意，One Call 3.0仅包含在“One Call by Call”订阅中。了解详情

If you you want to exclude some parts of the weather data from the API response please add exclude parameter to the API call like in the example below:

https://api.openweathermap.org/data/3.0/onecall?lat=33.44&lon=-94.04&exclude=hourly,daily&appid={API key}

If you do not need to exclude any of the weather data from the API response please use API call like in the example below:

https://api.openweathermap.org/data/3.0/onecall?lat=33.44&lon=-94.04&appid={API key}
