推荐答案
服务对任何视图都是完全不可知的.如果要使服务与特定视图关联，则应将其添加到特定父组件/指令内的提供程序列表中，并将ViewContainerRef作为参数传递给服务的方法之一.
Services are meant to be completely agnostic to any view. If you are trying to have a service associated with a particular view, then you should add it to the providers list within a specific parent component/directive and pass the ViewContainerRef as an argument into one of the service's methods.
