Angular 7中将ArrayBuffer转换为PDF

import { saveAs } from 'file-saver';
import * as pdfMake from 'pdfmake/build/pdfmake';
import * as pdfFonts from 'pdfmake/build/vfs_fonts';
pdfMake.vfs = pdfFonts.pdfMake.vfs;

generatePDF(arrayBuffer: ArrayBuffer): void {
  const uint8Array = new Uint8Array(arrayBuffer);
  const blob = new Blob([uint8Array], { type: 'application/pdf' });
  saveAs(blob, 'document.pdf');
}

const arrayBuffer = // 从服务器或其他地方获取的ArrayBuffer数据
this.generatePDF(arrayBuffer);
