本文主要实现给不同的用户推动不同的问候模板

准备工作

申请微信公众平台的测试号

申请微信测试公众号：

https://mp.weixin.qq.com/debug/cgi-bin/sandboxinfo?action=showinfo&t=sandbox/index

创建成功后，可以看到appid和appsecret，这个后面认证时需要

申请模板

可自行修改

今天是：{{now.DATA}} 不管那一天，每一天都是想你的一天 
当前城市：{{city.DATA}} 
今天的天气：{{text.DATA}}
最低气温：{{low.DATA}} 度
最高气温：{{high.DATA}} 度 
今天是我们想恋的第：{{scq_day.DATA}} 天 
距你的生日还有：{{bir_day.DATA}} 天 
{{daily_english_cn.DATA}} 
{{daily_english_en.DATA}}

新建成功后，记得保存模板Id后续有用

扫描关注该测试公众号

扫码关注后，记录微信号，后续推送通知用

申请百度天气

申请百度天气：

https://lbsyun.baidu.com/index.php?title=webapi/weather

完成认证后，创建一个应用，保存ak

申请天行数据的接口

申请天行数据

https://www.tianapi.com/

申请彩虹屁
申请每日一句

记得保存申请接口的key
