当我在HttpInterceptor类中注入一个使用HttpClient的服务时，Angular 6进入无限循环依赖循环

我已经在不同的Angular版本中多次发现了这个问题，但是多个消息来源说它已经修复了，例如，Stackoverflow上的另一个类似的问题是this answer，它说它是在Angular 5.2中解决的，some other issues on Github are saying it solved in 6.0.2，我使用的是Angular 6.0.3但是每当我尝试在我的HttpInterceptor类中注入一个使用HttpClient的服务时，我仍然会遇到这个问题（如果在该服务中收到jwt，则应该向请求添加一个jwt标记）

我没有得到一个警告或错误，我有循环依赖，我可以在浏览器控制台中看到拦截器正在调用服务的数千个请求，反之亦然 .

What is the proper way to handle this issue? （最好不要将jwt存储在localstorage中）

（即使用拦截器并从服务中获取jwt）

我的服务：

....
 // only showing parts that matter, HttpClient is injected here
 // to be used in calling the API services

  constructor(public http: HttpClient, private route: ActivatedRoute,
 public translate: TranslateService, private router: Router,
 public snackBar: MatSnackBar, private notification: NotificationService) {

//

我的HttpInterceptor：

import { Observable } from 'rxjs';
import { Location } from '@angular/common';
import { Injectable, Injector } from '@angular/core';
import { HttpInterceptor } from '@angular/common/http';
import { HttpRequest } from '@angular/common/http';
import { HttpHandler } from '@angular/common/http';
import { HttpEvent } from '@angular/common/http';
import { HttpHeaders } from '@angular/common/http';
import { DataService } from './data/data.service';

@Injectable()
export class CustomHttpInterceptor implements HttpInterceptor {
  constructor(private injector: Injector) {}

intercept(request: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
  const dataService = this.injector.get(DataService);

  console.log('hey there, we are here INTERCEPTOR');
  if (dataService.jwt) {
        request = request.clone({
          setHeaders: {
            Authorization: `Bearer ${dataService.jwt}`
          }
        });
      }

    return next.handle(request);
  }
}
