如何在angular中针对不同的请求多次调用同一个API

ng generate service api

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

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

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

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

  getData() {
    return this.http.get('https://example.com/api');
  }
}

import { Component, OnInit } from '@angular/core';
import { ApiService } from '路径/api.service';

@Component({
  selector: 'app-home',
  templateUrl: './home.component.html',
  styleUrls: ['./home.component.css']
})
export class HomeComponent implements OnInit {
  constructor(private apiService: ApiService) { }

  ngOnInit() {
    this.getData();
  }

  getData() {
    this.apiService.getData().subscribe((data) => {
      // 处理返回的数据
    });
  }
}
