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/hourly.json

https://api.caiyunapp.com/v2/TAkhjf8d1nlSlspN/121.6544,25.1552/hourly.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.json?lang=en_US&unit=metric&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））、（降水单位：mm/h）

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'】）

返回结构和说明
