changingThisBreaksApplicationSecurity angular2

Question

我正在尝试在 angular2 的标签中动态加载 pdf 文档，当我尝试更改 URL iths 时抛出一个错误说

SafeResourceUrlImplchangingThisBreaksApplicationSecurity: "localhost:8002/pdf.pdf"proto: SafeValueImplconstructor: SafeResourceUrlImpl()getTypeName: ()proto: Object

localhost:8002/pdf.pdf Failed to load resource: net::ERR_UNKNOWN_URL_SCHEME

这是我设置 URL 的方式， 当我需要显示组件时将调用此方法

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");
}

这是HTML部分

<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");
