Ionic4--iframe遇到的问题

遇到一个问题：iframe加载一个html一直报错，Error: Eequired a safe ResourceURL,got a HTML

 

解决办法：引入“DomSanitizer”

 

具体实现：

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

constructor(private sanitizer: DomSanitizer,) { 
 this.fileUrl= this.sanitizer.bypassSecurityTrustResourceUrl(res.data.link);
//注意是bypassSecurityTrustResourceUrl
//有些资料上写的是bypassSecurityTrustHtml，这个方法会报错
}

HTML：

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