unsafe：data：image / *; base64，：1 GET unsafe：data：image / *; base64，（Javascript / Angular）

Question

我從Spring Boot App中以JSON中的String64獲取圖像。

HTML

 <img id="userImage" src="{{ userImage }}"/>

打字稿

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

錯誤：

core.js：7909警告：清理不安全的URL值SafeValue必須使用[property] = binding：data：Image / *; base64，/ 9j / 4 ....

unsafe:data:image/*;base64,:1 GET unsafe:data:image/*;base64,

Answer 1

嘗試這個：

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

如果仍然有問題，請確保從后端獲取的圖像是正確的圖像。
