如何在 Angular 18.2.6 版本中显示图像？

Question

使用 Angular 版本 18.2.6（注意：有以前的 SO 线程，但没有适用于此版本）。

我有一个独立组件

NavbarComponent

，我想在其中包含图像。组件的 HTML：

<mat-toolbar class="toolbar">

    <a routerLink="/">
        <img src="" alt="IPCC Logo">
    </a>

      <a routerLink="/">
        <span style="font-size: 20px">Inpatient Psychological Care Collaborative (IPCC)</span>
      </a>
    
      <div class="spacer"></div>

      @if (true) {
        <ul id="nav-items">
          <li><a routerLink="/mission">Mission & Values</a></li>
          <li><a routerLink="/about">About Us</a></li>
          <li><a routerLink="/listserv">Listserv</a></li>
        </ul>
      }

</mat-toolbar>

...以及组件的 TS：

import { Component } from '@angular/core';
import { RouterModule } from '@angular/router';
import { MatToolbarModule } from '@angular/material/toolbar'

@Component({
  selector: 'app-navbar',
  standalone: true,
  imports: [
    RouterModule,
    MatToolbarModule
  ],
  templateUrl: './navbar.component.html',
  styleUrl: './navbar.component.css'
})
export class NavbarComponent {

}

图像存储在

/src/assets/images/logo.png

中，但代码编译时不显示，如下所示：

Answer 1

在 angular.json 文件中进行以下更改

"assets": [
          {
            "glob": "**/*",
            "input": "public",
            "output": "/"
          },
          {
            "glob": "**/*",
            "input": "src/assets",
            "output": "/assets"
          }
        ],
