将数组属性添加到此 Express.js 模型 class

Question

需要对以下代码进行哪些具体更改才能成功将属性添加到 JavaScript 模型对象中 JavaScript =25=] app? AppUser 代码放在 /app/models directory of this GitHub link.

的新 appuser.js 文件中

这是 AppUser class 的代码，包括数组的 getter 和 setter 的占位符，此 OP 询问如何编写：

var method = AppUser.prototype;

function AppUser(name) {
    this._name = name;
}

method.getName = function() {
    return this._name;
};

//scopes
method.getScopes = function() {
    //return the array of scope string values
};
method.setScopes = function(scopes) {
    //set the new scopes array to be the scopes array for the AppUser instance
    //if the AppUser instance already has a scopes array, delete it first
};
method.addScope = function(scope) {
    //check to see if the value is already in the array
    //if not, then add new scope value to array
};
method.removeScope = function(scope) {
    //loop through array, and remove the value when it is found 
}

module.exports = AppUser;

你可以像这样在 ES6 中使用 class :

'use strict';
module.exports = class AppUser {
  constructor(name) {
    this.name = name;
    this.scopes = [];
  }
  getName() {
    return this.name;
  }
  getScopes() {
    return this.scopes;
  }
  addScope(scope){
    if (this.scopes.indexOf(scope) === -1) this.scopes.push(scope);
  }
}
