上一篇了解微信开发者中心 URL的配置验证；
- 验证成功后，就可以对获取的接口权限进行操作
自定义菜单接口可实现多种类型按钮，用的比较多的是
1.click：点击推事件
用户点击click类型按钮后，微信服务器会通过消息接口推送消息类型为event 的结构给开发者（参考消息接口指南），并且带上按钮中开发者填写的key值，开发者可以通过自定义的key值与用户进行交互；
2、view：跳转URL
用户点击view类型按钮后，微信客户端将会打开开发者在按钮中填写的网页URL，可与网页授权获取用户基本信息接口结合，获得用户基本信息。
自定义菜单接口调用：
http请求方式：POST（请使用https协议） https://api.weixin.qq.com/cgi-bin/menu/create?access_token=ACCESS_TOKEN
ACCESS_TOKEN 需要通过接口获取
由于ACCESS_TOKEN 一天只能调用 2000，可以将ACCESS_TOKEN 保存起来，有效时间内不需要重新调用接口
