我正在尝试运行下载的Node.Js项目。我想使用Postman注册一个新的admin用户，并将此JSON发布请求cordova plugin add phonegap-plugin-barodescanner

发送到{"username" : "admin", "password" : "123", "admin" : "true"}点（相关代码位于https://localhost:3443/users/signup和users.js文件中）。我可以向新用户注册并登录，但是例如，当我想通过向authenticat.js点发送过帐请求（相关代码在https://localhost:3443/dishes内）来过帐时，它说您无权ti执行此操作。以下文件是项目的相关文件：
