在Angular 4中显示订阅数据

Question

我需要帮助在Angular 4中显示来自api的subscribe输出.我怎么能这样做,因为我写了data.data.data,但它说属性数据不存在于类型对象上.我将如何在浏览器中输出？这是我下面的代码和下面的api图片

import { Component, OnInit } from '@angular/core';
import { NewsService } from '../news.service';

@Component({
  selector: 'app-news-list',
  templateUrl: './news-list.component.html',
  styleUrls: ['./news-list.component.css']
})
export class NewsListComponent implements OnInit {

  constructor(private newsService: NewsService) { }

  ngOnInit() {

    this.newsService.getNews()
      .subscribe(
        data => {
          alert("News Success");
          console.log(data);
        },
        error => {
          alert("ERROR");
        });
  }
}

Answer 1

在组件中创建属性

myData: any[] = [];

并在您的订户功能

import { Component, OnInit } from '@angular/core';
import { NewsService } from '../news.service';

@Component({
  selector: 'app-news-list',
  templateUrl: './news-list.component.html',
  styleUrls: ['./news-list.component.css']
})
export class NewsListComponent implements OnInit {

  constructor(private newsService: NewsService) { }

  ngOnInit() {

    this.newsService.getNews()
      .subscribe(
        (res: any) => {
          alert("News Success");
          this.myData = res.data; 
          // Where you find the array res.data or res.data.data
          console.log('res is ', res.data);
        },
        error => {
          alert("ERROR");
        });
      }
    }

并在您的模板中

1)查看JSON的选项

<pre>{{myData | json}}</pre>

2)如果你有数组,循环选项

<div *ngFor="let d of myData">
    {{d}}
</div>
