Angular Ivy 类型检查 : Type 'SafeHtml' is not assignable to type 'string'

Question

我收到 typescript 错误 切换到 Ivy 编译器后:

[Step 4/5] src/app/app.component.html(1,26): Type 'SafeHtml' is not assignable to type 'string'.

在 Angular 类中有一个成员属性声明为 SafeHtml :

@Component({
  selector: 'app',
  template: `<div [innerHTML]="description"></div>`
})
export class AppComponent {
  description: SafeHtml;

  constructor(private sanitizer: DomSanitizer) {}

  ngOnInit(): void {
    this.description = this.sanitizer.sanitize(SecurityContext.HTML, '<strong>whatever comes from server</strong>');
  }
}

我的问题是如何转换 SafeHtml和 SafeUrl串？难道只是 .toString()好的？

Angular SafeHtml声明为:

/**
 * Marker interface for a value that's safe to use as HTML.
 *
 * @publicApi
 */
export declare interface SafeHtml extends SafeValue {
}

而 [innerHtml] 在 lib.dom.d.ts 中定义:

interface InnerHTML {
    innerHTML: string;
}

innerHtml是 string 的类型，而我有 SafeHtml .

如何重现:

git clone https://github.com/felikf/angular-repro-safe-html.git
npm i
npm run build
