Angular 中使用 FineReport不显示报表直接打印预览

<script type="text/javascript" src="/femisnsb/ReportServer?op=emb&resource=finereport.js"></script>

useJs(){
  alert("即将调用js直接打印");
  const url = "http://localhost:8080/femisnsb/ReportServer?reportlet=%E9%9D%A2%E6%96%99%E8%AE%A2%E5%8D%95%E5%8D%95%E6%8D%AE.cpt&mainId=43";
  const isPopup = false;
  const config = {url:url,isPopUp:isPopup};
  FR.doURLPDFPrint(config);
 }
