我在资产文件夹中创建了一个 json 文件。下面是json

    [
    {
        "userEmail": "IronMan@in.com",
        "comment": "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Praesent placerat metus at mauris sagittis interdum adipiscing placerat metus.",
        "commentDate": "08-01-2021 06:17:20 PM"
    },
    {
        "userEmail": "CaptainAmerica@in.com",
        "comment": "lLorem ipsum dolor sit amet, consectetur adipiscing elit. Praesent placerat metus at mauris sagittis interdum. Cras lacinia posuere egestas.",
        "commentDate": "08-01-2021 06:17:20 PM"
    }
]

我需要插入的 HTML 看起来像这样

<!-- new chat -->
            <div class="bx--col-lg-4 comment_section" style="position: fixed">
               <!-- <div class="check">
                  <strong>Start the discussion</strong>
               </div> -->
               <div class="test">
                  <strong>Start the discussion</strong><br>
                  <strong>Title</strong>
                  <p>More clarity is required on submitted evidence</p>
                  <div>
                     <strong>Adam's comment</strong> <br>
                     <label class="bx--label">10 March 2019</label>

我是 Angular 的新手，有人可以通过展示如何在服务中调用此 json 并填充 HTML 来解释我。此外，此服务将位于此组件中还是位于应用程序文件夹中的任何位置。

应用组件.ts

import { Component, VERSION, OnInit } from '@angular/core';

@Component({
  selector: 'my-app',
  templateUrl: './app.component.html',
  styleUrls: [ './app.component.css' ]
})

export class AppComponent implements OnInit  {

  data: Array<any>;

  ngOnInit(): void {

// This simulates fetching and parsing your JSON data
// from a service call. You will need to implement that
// yourself.
this.data = [
  {
    "userEmail": "IronMan@in.com",
    "comment": "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Praesent placerat metus at mauris sagittis interdum adipiscing placerat metus.",
    "commentDate": "08-01-2021 06:17:20 PM"
  },
  {
    "userEmail": "CaptainAmerica@in.com",
    "comment": "lLorem ipsum dolor sit amet, consectetur adipiscing elit. Praesent placerat metus at mauris sagittis interdum. Cras lacinia posuere egestas.",
    "commentDate": "08-01-2021 06:17:20 PM"
  }
];

} }

应用组件.html

<!-- This template uses the ngFor directive to create
 a comment for each element in your array. -->
<div *ngFor="let d of data" style="padding: 8px;">
  {{d.comment}}
  <br><span style="font-size: 12px; font-weight: bold;">{{d.userEmail}}</span>
  <br><span style="font-size: 10px;">{{d.commentDate}}</span>
</div>
