在angular 2+中使用--data-raw创建一个简单的http GET请求

ng generate service data

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

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

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

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

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

  constructor(private dataService: DataService) { }

  ngOnInit() {
    this.getData();
  }

  getData() {
    this.dataService.getData().subscribe((response: any) => {
      this.data = response;
    });
  }
}

<div *ngIf="data">
  <ul>
    <li *ngFor="let item of data">{{ item }}</li>
  </ul>
</div>
