企业微信开发之代开发应用
- 创建应用
- 安装应用
- 配置回调url
- 管理员授权，拿到临时授权码 auth_code，仅10分钟有效。需要在回调url中保存，并换取永久授权码 permanent_code
- 获取permanent_code流程如下：
- 获取 suite_ticket，配置回调URL后，每10分钟会传一次过来，保存备用
- 获取SuiteAccessToken
- 获取永久permanet_code
- 小程序中调用 wx.qy.login登陆 ，拿 到code, 获取 userid
- 获取userid流程如下
- 获取access_token，通过 corpid+permanet_code
- 通过 JSCODE2SESSION 获取 Userid (加密)
- 获取用户详情，通过 https://qyapi.weixin.qq.com/cgi-bin/user/get?access_token=%s&userid=%s"获取用户详情，只有deptment等信息。
