微信绑定用户服务端代码-根据code获取openId然后绑定用户
目录结构：
isa.qa.core.weixin.message.resp包和isa.qa.core.weixin.util包中为微信绑定的工具类，就不一一贴出代码，详见附件,下载地址：

openId绑定用户的代码，根据实际项目绑定代码按需修改，注意项目中如果使用了权限管理，注意把微信相关接口不拦截。

补充：
微信菜单的配置示例：

公众号配置的一些流程：
1.登录公众号 https://mp.weixin.qq.com/
2.启用开发者模式
3.进入开发-基本配置
4.填入相关信息，之一URL和Token都要对应上上面所配置的接口和设置的Token
5.网页授权获取用户信息 修改 修改为上一部URL中的 wechat.htib.com.cn
6.微信菜单的配置：
（1）.进入在线接口调试工具
（2）.配置菜单（先基础配置得到access_token，再使用access_token配置菜单）
