Angular 2、DomSanitizer、bypassSecurityTrustHtml、SVG [英] Angular 2, DomSanitizer, bypassSecurityTrustHtml, SVG

问题描述

我一直在将 DomSanitizer 与 html 字符串中的 SVG 一起使用.

在当前版本的 Angular 之前，这工作得很好:

this.domSanitizer.bypassSecurityTrustHtml(content);

现在我得到一个叫做

的对象

SafeHtmlImpl {changeThisBreaksApplicationSecurity: "

现在有访问 DomSanitizer 输出的新方法吗?我应该以 SafeHTML 类型或其他方式接收它吗?如果 bypassSecurityTrustHtml 仍然过滤 html，那么它有什么意义?

明信片上有答案吗?请...

解决方案

import { DomSanitizer } from '@angular/platform-b​​rowser'@Pipe({ 名称:'safeHtml'})导出类 SafeHtmlPipe 实现 PipeTransform {构造函数(私有消毒:DomSanitizer){}变换(值){console.log(this.sanitized.bypassSecurityTrustHtml(value))返回 this.sanitized.bypassSecurityTrustHtml(value);}}@成分({选择器:'我的应用'，模板:`<div [innerHtml]="html | safeHtml">

`，})出口类应用{名称:字符串；html:安全html；构造函数(){this.name = 'Angular2'this.html = "<svg>等等</svg>";}}

I've been using DomSanitizer with an SVG in an html string.

Previous to the current version of Angular, this worked just fine:

this.domSanitizer.bypassSecurityTrustHtml(content);

Now I am getting an object back called

SafeHtmlImpl {changingThisBreaksApplicationSecurity: "<svg> blah </svg>"}
changingThisBreaksApplicationSecurity

Is there now a new way to access the output of the DomSanitizer? Should I be receiving it as SafeHTML type or something? What's the point in having bypassSecurityTrustHtml if it still filters html?

Any answers on a postcard? Please...

import { DomSanitizer } from '@angular/platform-browser'

@Pipe({ name: 'safeHtml'})
export class SafeHtmlPipe implements PipeTransform  {
  constructor(private sanitized: DomSanitizer) {}
  transform(value) {
    console.log(this.sanitized.bypassSecurityTrustHtml(value))
    return this.sanitized.bypassSecurityTrustHtml(value);
  }
}

@Component({
  selector: 'my-app',
  template: `
    <div [innerHtml]="html | safeHtml">
    </div>
  `,
})
export class App {
  name:string;
  html: safeHtml;
  constructor() {
    this.name = 'Angular2'
    this.html = "<svg> blah </svg>";
  }
}
