Ionic4--iframe遇到的問題

遇到一個問題：iframe加載一個html一直報錯，Error: Eequired a safe ResourceURL,got a HTML

 

解決辦法：引入“DomSanitizer”

 

具體實現：

import { DomSanitizer } from "@angular/platform-browser";

constructor(private sanitizer: DomSanitizer,) { 
 this.fileUrl= this.sanitizer.bypassSecurityTrustResourceUrl(res.data.link);
//注意是bypassSecurityTrustResourceUrl
//有些資料上寫的是bypassSecurityTrustHtml，這個方法會報錯
}

HTML：

<iframe *ngIf="this.articleType == 'WD'||this.articleType == 'LJ'"
 height=100%
 width=100%
 [src]="fileUrl"></iframe>
