如何使用来自不同模块的两个同名 AngularJS 服务? [英] How to use two AngularJS services with same name from different modules?

问题描述

假设我有两个用于 AngularJS 的模块，例如foo 和 bar，它们都定义了一个名为 baz 的服务.

Supposed I have two modules for AngularJS, e.g. foo and bar, and both of them define a service called baz.

在我的应用程序中，我依赖它们说:

In my application I depend on them by saying:

var app = angular.module('app', [ 'foo', 'bar' ]);

然后我可以尝试使用baz服务在控制器中使用

Then I can try to use the baz service in a controller by using

app.controller('blaController', [ '$scope', 'baz', function($scope, baz) {
  // ...
}]);

如何定义我想使用这两种服务中的哪一种?是否有诸如完全限定名称之类的东西?

How can I define which of the two services I'd like to use? Is there something such as a fully-qualified name?

推荐答案

服务定位器按名称查找服务 (angularjs 指南 DI).但是 Namespacing"AngularJS 中的服务:

The service locator looks services up by name (angularjs guide DI). However "Namespacing" services in AngularJS:

截至今天，AngularJS 不处理服务的命名空间冲突所以如果你有 2 个不同的模块，服务名称相同方式并且您在应用程序中包含两个模块，则只会有一项服务可用.

As of today AngularJS doesn't handle namespace collisions for services so if you've got 2 different modules with the service named the same way and you include both modules in your app, only one service will be available.

我猜你可以手工"创建完全限定的名称:将服务命名为 foo.baz 和 bar.baz 而不是普通的 baz代码>.这是一种自我欺骗.此外，以这种方式编写它并不能使命名空间成为现实，但阅读代码的其他人可能会这么认为.

I guess you can make the fully qualified name "by hand": name the service foo.baz and bar.baz instead of plain baz. It's kind of a self-delusion. Moreover, writing it this way doesn't make namespacing real, but another person that reads the code might think so.
