Question

我有一个模块'moduleA'有2个服务，而一个（serviceB）依赖于另一个（serviceA）。我试图将serviceB注入一个属于不同模块'foo'的控制器，但是我得到了未知的提供程序错误。以下是我的代码：

module.js

angular.module('moduleA', []);

工厂a.js

angular
.module('moduleA')
.factory('factoryA', factoryA);

factoryA.$inject = ['$q', '$log', '$timeout'];

function factoryA($q, $log, $timeout) {
//Do Stuff
}

工厂b.js

angular
.module('moduleA')
.factory('factoryB', factoryB);

factoryB.$inject = ['factoryA'];

function factoryB(factoryA) {
//Do Stuff
}

FOO-controller.js

angular.module('foo', ['moduleA'])
       .controller('fooController', ['factoryB', function(factoryB){
//Do Stuff
})

控制台出错：

这可能听起来很简单，但您是否在项目中包含了 factory-b.js 文件？

我认为您应该修复下面显示的代码。除此之外，一切看起来都很好。

function factoryA($q, $log, $timeout) { //remove the ''
//Do Stuff
}

将多服务模块注入Controller时AngularJS未知提供程序错误
