本文版本：通用预报接口/v2.2，当前稳定版本版本：v2.5，历史版本：v2.2，v2.3，和 v2.4。

授权与认证

请先至彩云开放平台注册，注册后可以获得 token 。

把您的 token 拼到 API 请求的 URL 中，如

https://api.caiyunapp.com/v2/TAkhjf8d1nlSlspN/121.6544,25.1552/weather.json

其中 TAkhjf8d1nlSlspN 就是一个共用测试 token 。不要把私有token 告诉任何人！

请求样例

示例1如下

https://api.caiyunapp.com/v2/TAkhjf8d1nlSlspN/121.6544,25.1552/weather.json
https://api.caiyunapp.com/v2/TAkhjf8d1nlSlspN/121.6544,25.1552/weather.jsonp?callback=MYCALLBACK
token：这里是测试 token ，即 TAkhjf8d1nlSlspN
经纬度：经度在前，纬度在后，中间用半角逗号隔开，这里是 121.6544,25.1552
返回格式：json 或者 jsonp，jsonp 需提供回调函数名

示例2如下

https://api.caiyunapp.com/v2/TAkhjf8d1nlSlspN/121.6544,25.1552/weather?lang=en_US
语言选项 lang：默认为简体中文（zh_CN）、繁体中文（zh_TW）、美式英语（en_US）、英式英语（en_GB）
单位制选项 unit：默认为公制（metric）、科学单位体系（SI） 、英制（imperial）
时区偏移秒数 tzshift：用户提供所需时区偏移秒，考虑欧美夏令时，默认东八（tzshift=28800）；例如，用户希望取得印度（东5.5区）习惯定义下的逐日天气，加参数&tzshift=19800（=3600*5.5），然后daily的计算都会做相应处理。
定制返回的起始时间戳 begin：默认为当前utc时间戳，可以用来返回两日内的历史数据
定制返回逐小时预报总小时数 hourlysteps：默认为48小时（包括当前时刻）
定制返回逐日预报总天数 dailysteps：默认为5天（包括今天）
返回周围预警: alert=true (注意小写)

返回结构和说明

realtime分字段含义，请移步：实况接口/v2.2
minutely分字段含义，请移步：逐分钟降水短临预报接口/v2.2
hourly分字段含义，请移步：逐小时预报接口/v2.2
daily分字段含义，请移步：逐日预报接口/v2.2
alert分字段含义，如下：

支持的单位制

1.目前支持的单位制包括：科学单位体系（SI，大写）、英制（imperial）、公制（不带参数&unit默认公制，公制还包括: metric:v1和metric:v2）:

单位制
要素
 SI（科学单位体系） imperial（英制） metric:v1（公制v1） metric:v2（公制v2） default metric(默认公制)
实况降水量 米/秒(meter/sec) 英寸/小时(in/hr) 雷达降水强度（0~1） 毫米/小时(mm/hr) 雷达降水强度（0~1）
逐分钟降水短临预报降水量 米/秒(meter/sec) 英寸/小时(in/hr) 雷达降水强度（0~1） 毫米/小时(mm/hr) 雷达降水强度（0~1）
逐小时预报降水量 米/秒(meter/sec) 英寸/小时(in/hr) 雷达降水强度（0~1） 毫米/小时(mm/hr) 毫米/小时(mm/hr)
逐日预报降水量 米/秒(meter/sec) 英寸/小时(in/hr) 雷达降水强度（0~1） 毫米/小时(mm/hr) 毫米/小时(mm/hr)

风向 从北顺时针(0~360°) 从北顺时针(0~360°) 从北顺时针(0~360°) 从北顺时针(0~360°) 从北顺时针(0~360°)
风速 米/秒（m/s） 英里/小时（mi/hr） 公里/小时（km/hr） 公里/小时（km/hr） 公里/小时（km/hr）
云量 0~1 0~1 0~1 0~1 0~1
能见度 米(m) 英里(mi) 公里(km) 公里(km) 公里(km)

unit=metric:v1时，所有类型中precipitation的单位都是：雷达降水强度（0~1）

unit=metric:v2时，所有类型中precipitation的单位都是：毫米/小时(mm/hr)

2.判断降水等级:

  • 带参数&unit=metric:v1，请求实况、分钟级、逐小时和逐日降水强度，单位都为雷达降水强度（0 ~ 1）；
  • 雷达降水强度（0 ~ 1）判断降水等级：0.03~0.25 小雨(雪)， 0.25~0.35 中雨(雪)， 0.35~0.48大雨(雪)， >0.48 暴雨(雪)；
  • v2.4版本中，本地存在降水时，可以根据skycon（存在于realtime、hourly、daily字段），和skycon_08h_20h和skycon_20h_32h（存在于daily字段），中的：LIGHT_RAIN, MODERATE_RAIN, HEAVY_RAIN, STORM_RAIN(LIGHT_SNOW, MODERATE_SNOW, HEAVY_SNOW，STORM_SNOW)直接获取降水等级
  • 大暴雨(雪)和特大暴雨(雪)，需要根据24小时累计公制降水量（mm/24hr）来判断，研发中...
