HA中燃插件

这是中燃的燃气插件，抓包后的api还是比较友好的

0.抓包

---

按照国际惯例，首先抓包。从小程序入手，微信搜索 中燃慧生活 。然后打开抓包工具，开始抓包即可

1.分析抓包数据

---

中燃的接口还是挺友好的，都是json格式的。查看抓包的数据，找到这么一个地址 https://zrds.zrhsh.com/controller/payfee/getcustomerMoneyListForMp.do ，这个地址里面有咱想要的数据。数据咱就不贴了，都是看的到的。

2.开发插件

---

分析数据，插件代码如下：

4.配置HA

---

插件需要客户号，上面抓包的请求就有，拿就完事了。接着照着下面配置就行。配置完成后，重启HA就行了

- platform: zrgas
    name: '燃气费'
    custCode: 'XXXXXXX'

5.成果展示

至此，家里的水电燃气已经接入完毕，后面再把其他的整理整理，分享出来。
