TypeScript

import {UserService} from "./services/user/user.service";
import {DomSanitizer} from "@angular/platform-browser";

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

  private user:any;
  private userImage:any;

  constructor(private userService:UserService, private sanitizer: DomSanitizer) {}

  ngOnInit() {
    //TODO hardcoded...
    this.getUser("admin");
  }

  getUser(username) {
    this.userService.getUser(username).subscribe(user => {
      console.log(user);
      this.user = user;
      this.userImage = this.sanitizer.bypassSecurityTrustUrl("data:Image/*;base64," + user.image);

Answer 1

Try this:

<img id="userImage" [src]="userImage"/>

If you still have problems, please make sure the image you get from the backend is a proper image.
