概述
一键登录：用户无需输入手机号码，一键点击即可快速完成注册/登录流程，提高转化率优化用户体验。
申请资源
发起请求前，需要极光后台获取配置：
应用设置-应用信息
AppKey：xxxx
Master Secret：xxxx
应用设置-认证设置
iOS-Bundle ID：com.lx.xxx
一键登录-RSA加密公钥：xxx
密钥生成：https://xuanxuanblingbling.github.io/ctf/web/2019/05/10/rsa/
RSA公钥会在极光返回手机号的时候加密，服务端用对应的私钥去解密，获取手机号
认证流程和时序图
认证流程：
- 客户端调用极光认证SDK，启动认证流程，需要向极光发起请求
- 极光返回用户的token
- 客户端将token发送给服务端，接口 user/account/shanyan_login
- 服务端将客户端请求中的token,向极光请求返回手机号，接口：https://api.verification.jpush.cn/v1/web/loginTokenVerify
- 极光验证token是否有效
- 极光返回用户的手机号
- 服务端返回用户的UID和Session ID

}
UserManager.instance.updateLoginUser(dd);
} else {
TToast.show(dd['error_msg'] ?? '网络不给力');
