后端使用fastReport，vue前端通过window.open 打开pdf文档

PrintFormPDF(data) {
      this.$API
        .UserPrintPDF(data)
        .then((res) => {
          this.$nextTick(() => {
            let oldsplit = res.data.Data.split("/"); // 用“/”分隔
            oldsplit.splice(0, 1); //删除第一个
            let newsplit = oldsplit;
            let newPdf = newsplit.join("/"); //数组转字符串
            let Pdffile = { url: this.$FWurl + newPdf }; //最后的url地址
            window.open(Pdffile.url, "_blank");
          });
        })
        .catch((err) => {
          this.$notify.error({
            title: "消息提示",
            message: err,
          });
        });
    },
