实际项目中需要获取在企业微信中员工的信息，这边做下记录
首先了解企业微信的API
https://work.weixin.qq.com/api/doc#10013
1，自己注册一个测试的企业微信，在应用与小程序里面创建自己的测试应用，在企业微信上发布第三方应用
2，详情看API，主要看关于
3，获取员工信息的思路是（1）通过鉴权的回调获取code（2）固定地获取access_token，（3）通过code和access_token获取UserId（4）通过UserId获取员工信息
（1）通过鉴权的回调获取code：
（2）固定地获取access_token：
corpid：我的企业---->企业信息----->
corpsecret:
这里面有两种不同叫法的token
解释：
（3）通过code和access_token获取UserId
（4）通过UserId获取员工信息
注：这个接口在：不在当前页面，因为是第三方，不需要获取user_ticket，再去获取员工信息

最后，部署完企业微信中应用的url，将后台前台代码发布到外网，在手机端测试，能看见打印员工的name+mobile+email，必须在手机端测，因为code值只能从手机端获取。
拿着员工信息可以做进一步的鉴权。
遇到的一些坑，token的两种获取方式，其实都一样，code只能用一次，因为调试必须每改一行代码就得发布到外网，code，一般都已经被消耗了，你就不能通过微信web开发工具看code，再用它去调试之后的接口，主要是code这个导致第一次玩企业微信，调试要半天！
完。
