If you are going the Http interceptor route, then you can just take advantage of using either an event emitter and then listen for messages related to the call you are checking for.如果您要使用 Http 拦截器路由，那么您可以利用任一事件发射器，然后侦听与您正在检查的呼叫相关的消息。 Another thing you can do would be to have a service that you set in the interceptor, but also you can listen for you the component.您可以做的另一件事是在拦截器中设置一个服务，但您也可以监听组件。
