Javascript AngularJS论证'；fn'；不是函数，未定义

我对AngularJS 1.6有问题，错误消息是：

错误：[ng:areq]参数“fn”不是函数，未定义

我知道这是我的testService的问题，请帮助查找问题

所以ApiConstant工作正常，但TestService生成错误，当我将从控制器中删除TestService时，它的工作正常，这可能是什么？

模块依赖项应该是字符串：

错误的

angular.module('myApp', [
    uiRouter,
    Components
  ])

应该是：

angular.module('myApp', [
    'uiRouter',
    'Components'
  ])

可能与您的服务是一个箭头函数有关，同时也使用

此

更改为导出默认函数TestService（apiconstat），但不起作用hmm您能创建一个实例吗？
