微信企业号二次开发（推送和获取用户信息）

微信企业号不同于公众号和服务号，它提供了比较强大的接口，可以自由开发出各种应用和功能

----------------------利用微信企业号推送用户信息-----------------------------

// 将数据转换成json

---------------------------获取访问用户的信息-----------------------------

插入在企业号应用中的菜单网址设置如下：

https://open.weixin.qq.com/connect/oauth2/authorize?appid=ww40fde***&redirect_uri=http%3a%2f%2fczxiexm-test.iask.in:11118%2fqyh_app%2fServlet_user&response_type=code&scope=snsapi_base&agentid=1000***&state=1#wechat_redirect

appid=ww40fde***  //在“我的企业”里面的CorpID

agentid=1000*** //企业应用 里面的某一个应用的AgentId

redirect_uri=http%3a%2f%2fczxiexm-test.iask.in:11118%2fqyh_app%2fServlet_user 

//可信域名，需在企业应用里面：跟 网页授权及JS-SDK 设置一样，后面带的文件是后台响应的文件

后台代码：

通过企业号点击上面那条连接，后台Servlet_user可以通过 String code=request.getParameter("code"); 得到code值
