Primeng Datatable内的角度2管道给出安全错误

Question

我有一个管道解码html代码。例如<p>test</p>成为test

当我使用它的列里面，它不显示数据，但 'SafeValue must use [property]=binding: XXXX (see http://g.co/ng/security#xss)'

DATATABLE

<p-dataTable [value]="toShowSubVragen"> 

    <!-- WITH Pipe, DOESN'T WORK 
    SHOWS: SafeValue must use [property]=binding: XXXX (see http://g.co/ng/security#xss)--> 
    <p-column field="tekst" header="With Pipe"> 
     <template let-col let-vraag="rowData" pTemplate="body"> 
      <span>{{vraag[col.field] | safeHtml}}</span> 
     </template> 
    </p-column> 

    <!-- WITHOUT Pipe, WORKS 
    SHOWS: the tekst data.. --> 
    <p-column field="tekst" header="Without Pipe"> 
     <template let-col let-car="rowData" pTemplate="body"> 
      <span>{{car[col.field]}}</span> 
     </template> 
    </p-column> 

</p-dataTable> 

管

@Pipe({ name: 'safeHtml'}) 
export class SafeHtmlPipe implements PipeTransform { 
    constructor(private sanitized: DomSanitizer) {} 
    transform(value) { 
    return this.sanitized.bypassSecurityTrustHtml(value); 
    } 
} 

我该如何解决这个问题？

Answer 1

使用safeHtml或直接与{{}}消毒剂是没有意义的，因为结果是字符串化，解除的| safeHtml应用。

<span>{{vraag[col.field] | safeHtml}}</span> 

也许你的意思是

<span [innerHTML]="vraag[col.field] | safeHtml"></span>
