可以简化提供单个 gettable/settable 变量的服务吗? [英] Can a service that provides a single gettable/settable variable be simplified?

问题描述

我有这样的服务:

var app = angular.module('someModule');
app.factory('token', function() {
  var token = null;
  return {
    get: function() {
      return token;
    },
    set: function(tokenIn) {
      token = tokenIn;
    }
  };
});

我宁愿有这样的东西:

app.variable('token', null);

在 POJO 工作了 5 年之后，我对 getter/setter 有了小而强烈的仇恨.有没有更好的方法来用 angular 做到这一点?provide.constant 和 provide.value 似乎不符合要求.我也找不到可以执行此操作的插件 - 是否有一些我不知道的概念的词汇?

After 5 years of POJOs, I'm have a small but intense hatred for getter/setters. Is there a better way to do this with angular? provide.constant and provide.value didn't seem to fit the bill. I couldn't find a plugin to do this either-- is there some vocabulary for this concept I am ignorant of?

推荐答案

你可以像这样直接使用对象:

You can just use the object directly something like:

myApp.factory('token', function(){
    return { Token : '' };
});

然后您可以将 token 工厂注入您的控制器，并按如下方式获取或设置令牌:

Then you can inject the token factory into your controller and either get or set the token as follows:

myApp.controller("Test", function ($scope, token) {
    // set:
    token.Token = 'abc';
    // or get
    var local = token.Token;
});

这与您所能获得的POJO"差不多.希望有帮助！

This is about as close to a "POJO" as you can get. Hope that helps!
