深究AngularJS——自定义服务详解(factory、service、provider)

前言

3种创建自定义服务的方式。
1. Factory
2. Service
3. Provider
大家应该知道，AngularJS是后台人员在工作之余发明的，他主要应用了后台早就存在的分层思想。所以我们得了解下分层的作用，如果你是前端人员不了解什么是分层，那么你最好问问你后台的小伙伴。
dao层：就是Model层，在后台时，这一层的作用，就要是写与数据库交互数据的一层，在angularJS里就主要是写ajax的。
service层：主查写逻辑代码的，但在angularJS里也可以持久化数据（充当数据容器），以供不同的controller高用。
controller层：即控制层，在angularJS里就是写控制器的。控制器里尽量不要写那些不必要的逻辑，尽量写在service层里。
所以，就有了创建自定义服务的三种方式。

factory

factory方式创建的服务，作用就是返回一个有属性有方法的对象。相当于：var f = myFactory();

在自定义服务里注入服务示例，但不能注入$scope作用域对象。

service

通过service方式创建自定义服务，相当于new的一个对象：var s = new myService();，只要把属性和方法添加到this上才可以在controller里调用。

3.provder

只有provder是能传 .config() 函数的 service。如果想在 service 对象启用之前，先进行模块范围的配置，那就应该选择 provider。需要注意的是：在config函数里注入provider时，名字应该是：providerName+Provider.
使用Provider的优点就是，你可以在Provider对象传递到应用程序的其他部分之前在app.config函数中对其进行修改。
当你使用Provider创建一个service时，唯一的可以在你的控制器中访问的属性和方法是通过$get()函数返回内容。
