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

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）:
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) 距离 米(m) 英里(mi) 公里(km) 公里(km) 公里(km) 温度 开尔文(K) 华氏度(℉) 摄氏度(℃) 摄氏度(℃) 摄氏度(℃) 气压 帕(Pa) 帕(Pa) 帕(Pa) 帕(Pa) 帕(Pa) 相对湿度 0~1 0~1 0~1 0~1 0~1 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...
