Chrome在Angular 4- Observable中说“无法获取/”

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';
import { Observable } from 'rxjs';

@Injectable({
  providedIn: 'root'
})
export class DataService {
  private apiUrl = '/api/data'; // 确保这个路径是正确的

  constructor(private http: HttpClient) {}

  getData(): Observable<any> {
    return this.http.get(this.apiUrl);
  }
}

import { Component, OnInit } from '@angular/core';
import { DataService } from './data.service';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
  data: any;

  constructor(private dataService: DataService) {}

  ngOnInit() {
    this.dataService.getData().subscribe(
      response => {
        this.data = response;
      },
      error => {
        console.error('There was an error!', error);
      }
    );
  }
}
