/*
思路:
1. 浏览器打开
        用户名+密码 登录 与企业微信没有交集
        手机企业微信登录->扫码页面->扫码后获取用户信息, 判断是否绑定了企业微信
            已绑定，则读取用户信息，直接登录
            未绑定，则弹窗提示[未绑定企业微信，请先在企业微信中打开，完成绑定]
2. 企业微信打开->自动登录->判断是否绑定了企业微信
        已绑定，则读取用户信息，直接登录
        未绑定，则弹窗提示
            是否已有账户(用户名+密码方式)
                有: 弹窗输入[用户名+密码+验证码]校验
                无: 直接以企业UserId作为用户名(小写)，创建随机密码
