我终于能够解决这个问题了……我使用了pdfjsLib，并在ts文件中导入了*(作为pdfjsLib从‘pdfjs-dist/build/pdf’导入；)

 public src="/assets/myPhotos.pdf";
 showPdf(){
pdfjsLib.getDocument(this.src).then(doc =>{

 // console.log("this file has "+ doc._pdfInfo.numPages+ "pages");
  doc.getPage(1).then(page => {
    var myCanvas =  <HTMLCanvasElement>document.getElementById("my_canvas");
    var context = myCanvas.getContext("2d");
    var scale = 1.5;
    var viewport = page.getViewport(scale);
    myCanvas.width = viewport.width;
    myCanvas.height = viewport.height;

    page.render({
      canvasContext : context,
      viewport : viewport
    })
  })
});

}
