自动消毒

为了系统地阻止 XSS 错误,Angular 默认情况下将所有值视为不可信。当一个值通过属性、属性、样式、类绑定或插值从模板插入 DOM 时,Angular 会清除和转义不受信任的值。

但是,可以将值标记为可信,并使用以下方法阻止自动清除:

  • bypassSecurityTrustHtml
  • bypassSecurityTrustScript
  • 旁路安全信任样式
  • bypassSecurityTrustUrl
  • bypassSecurityTrustResourceUrl

使用不安全方法的组件示例 bypassSecurityTrustUrl

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

@Component({
  selector: 'my-app',
  template: `
    <h4>An untrusted URL:</h4>
    <p><a class="e2e-dangerous-url" [href]="dangerousUrl">Click me</a></p>
    <h4>A trusted URL:</h4>
    <p><a class="e2e-trusted-url" [href]="trustedUrl">Click me</a></p>
  `,
})
export class App {
  constructor(private sanitizer: DomSanitizer) {
    this.dangerousUrl = 'javascript:alert("Hi there")';
    this.trustedUrl = sanitizer.bypassSecurityTrustUrl(this.dangerousUrl);
  }
}

XSS

在进行代码审查时,您希望确保没有用户输入是可信的,因为它会在应用程序中引入安全漏洞。
