如何使用自定义API连接Spartacus

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

@Injectable({
  providedIn: 'root'
})
export class CustomApiService {
  constructor(private http: HttpClient) {}

  getCustomData(): Observable<any> {
    return this.http.get('/api/custom-data');
  }
}

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

@Injectable({
  providedIn: 'root'
})
export class CustomApiService {
  private apiUrl = '/api/custom-data';
  private headers = new HttpHeaders({
    'Authorization': 'Bearer ' + localStorage.getItem('token')
  });

  constructor(private http: HttpClient) {}

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

import { Injectable } from '@angular/core';
import { HttpClient, HttpHeaders } from '@angular/common/http';
import { Observable, throwError } from 'rxjs';
import { catchError } from 'rxjs/operators';

@Injectable({
  providedIn: 'root'
})
export class CustomApiService {
  private apiUrl = '/api/custom-data';
  private headers = new HttpHeaders({
    'Authorization': 'Bearer ' + localStorage.getItem('token')
  });

  constructor(private http: HttpClient) {}

  getCustomData(): Observable<any> {
    return this.http.get(this.apiUrl, { headers: this.headers }).pipe(
      catchError(error => {
        console.error('Error:', error);
        return throwError('Something went wrong');
      })
    );
  }
}
