如何在调用 API 时使用 DOMSANITIZER(bypassSecurityTrustUrl)

Question

Getting XSS vulnerabilities while calling the API for fetching the data. So trying to add DOMSANITIZER , but its failing. Tried below code, please suggest me the solution.

 this.http.get(this.domSanitizer.bypassSecurityTrustUrl(dataUrl),{headers:headers}).subscribe(response => {
      this.persons = response.data.map(x=>({...x,check:false,test:x.firstName}));
      this.dtTrigger.next();
    });

Answer 1

You can use DOMSANITIZER while using the API in following way.

1. Import these:

 import { Component, OnInit, ViewChild, SecurityContext, } from '@angular/core'; import {DomSanitizer} from '@angular/platform-browser';

2. Use this below code in your project where you are using this:

 const dataUrl = this.domSanitizer.sanitize( SecurityContext.RESOURCE_URL, this.domSanitizer.bypassSecurityTrustResourceUrl( 'https://raw.githubusercontent.com/l-lin/angular-datatables/master/demo/src/data/data.json' ) ); this.http.get(dataUrl).subscribe((response) => { this.persons = response.data.map((x) => ({ ...x, check: false, test: x.firstName, })); this.dtTrigger.next(); });

Important:

This code is working on your stackblitz url.
