angular - Angular2 中的 iframe

Question

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

@Component({
  selector: 'my-app',
  template: `<h1>Hello {{name}}</h1>
             <iframe src="http://hssa:1021/Home?testRequestId=+[testRequestId]+" allowfullscreen></iframe>`,
})
export class AppComponent  {
    name = 'Angular';
    testRequestId = '3224'; 
}

我有上面提到的 .ts 文件。如何将 testRequestId 传递给 html？

Answer 1

试试这个:

Online demo

安全管道

import { Pipe, PipeTransform } from '@angular/core';
import { DomSanitizer} from '@angular/platform-browser';

@Pipe({ name: 'safe' })
export class SafePipe implements PipeTransform {
  constructor(private sanitizer: DomSanitizer) {}
  transform(url: string) {
    return this.sanitizer.bypassSecurityTrustResourceUrl(url);
  }
}

应用组件

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

@Component({
  selector: 'app-root',
  template: `
    <iframe [src]="'https://www.youtube.com/embed/' + testRequestId | safe" width="560" height="315" allowfullscreen></iframe>
  `
})
export class AppComponent {
  testRequestId: string = 'uelHwf8o7_U';

}

因为 Angular 不信任任何来源，它会清理内容，然后我们需要绕过它。
