Issue
I am trying to sanitize a pdf url and want to assign it to a string type variable so that I can use it for pdf viewer. Is there any way to do that?
If I use any
type for pdfSrc type, I am getting Invalid parameter object: need either .data, .range or .url in the <pdf-viewer>
.
Note: The URL which I used is for reference purpose, i would use external URLs in that place
landingpage.component.ts
import { DomSanitizer, SafeResourceUrl, SafeUrl } from '@angular/platform-browser';
export class LandingpageComponent implements OnInit {
public pdfSrc: string;
}
constructor(
private sanitizer: DomSanitizer) {
}
fnOpenAsset() {
let url = 'http://localhost/pdf_viewer-master/18/docs/pdf.pdf';
this.pdfSrc = this.sanitizer.bypassSecurityTrustResourceUrl(url);
}
landingpage.component.html
<pdf-viewer class="alignComponentCenter" [src]="pdfSrc"
</pdf-viewer>
Solution
I got a way to fix this. I tried sanitizing the SafeResourceUrl again with sanitize()
method whose return value is string | null.
In case you want to use bypassSecurityTrustUrl()
, then SecurityContext.URL
will take place. In my case I used SecurityContext.RESOURCE_URL
export class LandingpageComponent implements OnInit {
public pdfSrc: string;
}
constructor(
private sanitizer: DomSanitizer) {
}
fnOpenAsset() {
let url = 'http://localhost/pdf_viewer-master/18/docs/pdf.pdf';
this.pdfSrc = this.sanitizer.sanitize(SecurityContext.RESOURCE_URL, this.sanitizer.bypassSecurityTrustResourceUrl(url));
}
