配列内の各要素のbypassTecureResourceUrlをバイパスする方法はありますか？

Question

Googleマップの埋め込みAPI URLの配列があります。ただし、各項目を繰り返し処理してiFrameのソースにバインドするときは、

私は以下を使用できます。

constructor(private sanitizer: DomSanitizationService) { 
    this.url = sanitizer.bypassSecurityTrustResourceUrl('https://www.google.com/maps/embed/v1/place?key=KEY&q=365 Badger Ave, Newark, New Jersey 07112'); 
} 

しかし、私は各項目についてこれを行う必要があります。更新する外部ソースから配列を受け取ったので、私はそうすることができません。

どのように私のURLごとにセキュリティをバイパスできますか？

はここで、以下のようにあなたがDomSanitizationServiceでPIPEを使用することができますapp.component.ts

import { Component, Pipe } from '@angular/core'; 
import { DomSanitizationService } from '@angular/platform-browser'; 
@Pipe({name: 'secureUrl'}) 
export class Url { 

    constructor(private sanitizer:DomSanitizationService){ 
    this.sanitizer = sanitizer; 
    } 

    transform(url) { 
     return this.sanitizer.bypassSecurityTrustResourceUrl(url).changingThisBreaksApplicationSecurity;    
    } 
} 
@Component({ 
    selector: 'my-app', 
    pipes: [Url], 
    template: ` 
    <div class="container"> 
     <div style="padding-top: 20px"> 
     <div class="row" *ngFor="let row of rows"> 
      <div *ngFor="let event of row">

var chunk_size = 3; 
const GROUPS = EVENTS.map(function(e,i){ 
    return i%chunk_size===0 ? EVENTS.slice(i,i+chunk_size) : null; 
}) 
.filter(x=>!!x)

です。

//our root app component 
import {Component, Pipe} from '@angular/core' 
import {DomSanitizationService} from '@angular/platform-browser'; 

@Pipe({name: 'secureUrl'}) 
export class Url { 

    constructor(private sanitizer:DomSanitizationService){ 
    this.sanitizer = sanitizer; 
    } 

    transform(url) { 
     return this.sanitizer.bypassSecurityTrustResourceUrl(url).changingThisBreaksApplicationSecurity;    
    } 
} 


@Component({ 
    selector: 'my-app', 
    pipes: [Url], 
    template: ` 
    <div *ngFor="let item of myUrls; let i = index"> 
     {{item.url|secureUrl}} 
    </div> 
    `, 
}) 
export class AppComponent { 
    myUrls=[{url:"google.com"},{url:"google1.com"},{url:"google2.com"}]; 
}
