个人公众号服务端开发Demo

公众号出来很久了，也可以个人申请。知道公众号的服务端开发其实很简单，接口调用封装，数据存取，不外如是。

人一旦懒了，真的是 “无可救药” 了。。。现简单描述晚到的公众号HelloWorld

• 思路

公众号里面简单的文章展示，静态博客展示这种好像没啥特别的，就跳过了。

在聊天框输入参数， 传到云服务器处理，然后请求个三方API获取信息，封装返回。嗯，这就算个基本的Demo了

• 准备

1， 得申请个公众号，个人的，免费

2， 最好买一台云服务器，双十一的阿里云最低100￥/Year，heihei

• Let‘s go

按照 微信的公众号对接的文档来就可以了，直接贴代码
