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:v2.2v2.3,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&hourlysteps=2&daylysteps=2&getplacename=True
经纬度附近地址中英文名称 getplacename:True
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:默认为东八区,tzshift=28800;例如:印度东5.5区,tzshift=3600*5.5==19800,v2.3之后版本,返回时区信息,使用秒是为了支持像尼泊尔这样的差 5 小时 45 分钟的地区,它们有非整齐的偏移量
定制返回逐小时预报总小时数 hourlysteps:默认为120小时
定制返回逐日预报总日数 daylysteps:默认为5天
定制返回变量列表 fields:tmp,vis 默认返回所有变量,【'ast', 'rad', 'prc', 'tmp', 'wnd', 'hmd', 'cld', 'aqi', 'pm25', 'pm25w', 'sky', 'skyh', 'lfi', 'alr', 'pres', 'vis', 'dswrf'】
定制是否返回气象预警信息(中国气象局预警中心)alert:true (注意不要大写)
定制返回数据的起始时刻 begin:begin=1543072172 utc时间戳整数(可以返回最近的历史两天数据)
