将数据从使用http的angular 2服务传递到组件

import { HttpClient } from '@angular/common/http';
import { Observable } from 'rxjs';
import { map } from 'rxjs/operators';

@Injectable()
export class DataService {
  constructor(private http: HttpClient) {}

  getData(): Observable<any> {
    return this.http.get('https://example.com/api/data').pipe(
      map(response => response.data)
    );
  }
}

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

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

  constructor(private dataService: DataService) {}

  ngOnInit() {
    this.dataService.getData().subscribe(data => {
      this.data = data;
      // 在这里可以对数据进行进一步处理或使用
    });
  }
}

<div *ngIf="data">
  <h1>Data: {{ data }}</h1>
</div>
