角度httpclient不使用绝对url

我用 Angular 7 和 HttpClient

import { HttpClient, HttpHeaders, HttpResponse, HttpRequest, HttpParams } from '@angular/common/http';

...

this.http.get(this.appConfigService.apiUrl + url, {headers: this.getHeaders(),  params: urlParams} )

this.appConfigService.apiUrl 包含: https//xxxx-api.eu-west-3.amazonaws.com:80/int/

但是我的ajax调用是 http://localhost:4200/https//xxxx-api.eu-west-3.amazonaws.com:80/int/meeting

http://localhost:4200/ 在url的开头?
