飞书告警
登陆飞书移动端后，点击 "添加账号"
现在登陆的是管理员账号，账号只有审批权限，没有创建应用的权限
我们要切换成能创建应用的账号的权限
登陆飞书Web端
1.https://open.feishu.cn/app
飞书后台，可以创建应用，但是需要管理员审批
2.https://va8ocx82fwg.feishu.cn/admin/appCenter/audit
飞书后台，可以审批应用，但是没办法创建应用
授权的时候 选择 "授权登陆全部账号"
这样就能在一个浏览器上同时登陆"管理员审批账号"和"创建应用账号"
飞书Web端创建应用 https://open.feishu.cn/app
申请应用的权限
这下面有多页，记得最下面翻页，我自己就是管理员，所以权限值直接通过的
创建版本和申请发布应用
飞书Web端审批应用 https://va8ocx82fwg.feishu.cn/admin/appCenter/audit
记录App ID和AppSecret （后续很重要）
