改变ThisBreaksApplicationSecurity 角度2

Question

我正在尝试动态地在 angular2 中的标签中加载 pdf 文档，当我尝试更改 URL 时，会抛出错误

SafeResourceUrlImplchangingThisBreaksApplicationSecurity：“localhost：8002/pdf.pdf”原型：SafeValueImpl构造函数：SafeResourceUrlImpl（）getTypeName：（）原型：对象

本地主机：8002/pdf.pdf 无法加载资源：net::ERR_UNKNOWN_URL_SCHEME

这是我设置 URL 的方法，当我需要显示组件时会调用此方法

public show(): void {
    this.visible = true;
    this.visibleAnimate = true;
    console.log(this.src)
    this.DocURL = this.sanitizer.bypassSecurityTrustResourceUrl(this.src);
    console.log(this.DocURL);
}


constructor(private sanitizer: DomSanitizer) {
    this.visible = false;
    this.visibleAnimate = false;

    this.DocURL = this.sanitizer.bypassSecurityTrustResourceUrl(window.location.host + "/pdf.pdf");
}

HTML 部分如下

<div style=" height:650;width:870">
    <object width="870" height="650" type="application/pdf" [data]="DocURL" id="doc" #doc>
        <p>Not able to display the document</p>
    </object>
    <div style="display:none">
        <iframe id="fred" #fred style="border:1px solid #666CCC" title="PDF in an i-Frame" [src]="DocURL" frameborder="1" scrolling="auto" height="1100" width="850" ></iframe>
    </div>
</div>

我提供的 URL 将是动态的

您的 URL 没有协议。请尝试以下操作：

this.DocURL = this.sanitizer.bypassSecurityTrustResourceUrl(window.location.protocol + '//' + window.location.host + "/pdf.pdf");
