最近项目中使用到了获取天气相关信息，这里我使用了和风天气接口来实现此功能
和风天气接口API：API开发文档 | 和风天气开发平台
一：获取实时天气
1：接口地址
商业版：/v7/weather/now?
开发版：/v7/weather/now?
2：请求参数
key：用户认证key
location：需要查询地区的经纬度(经度,纬度)
3：返回数据
// 北京实况天气 // 商业版 /v7/weather/now?location=101010100&key=你的KEY// 开发版 /v7/weather/now?location=101010100&key=你的KEY{"code": "200","updateTime": "-06-30T22:00+08:00","fxLink": "http://hfx.link/2ax1","now": {"obsTime": "-06-30T21:40+08:00","temp": "24","feelsLike": "26","icon": "101","text": "多云","wind360": "123","windDir": "东南风","windScale": "1","windSpeed": "3","humidity": "72","precip": "0.0","pressure": "1003","vis": "16","cloud": "10","dew": "21"},"refer": {"sources": ["Weather China"],"license": ["commercial license"]}}
二：获取未来七天天气
1：接口地址
商业版：/v7/weather/7d?
