前端导出pdf文件

this.$get(url, {}, { responseType: 'blob' }).then(res => {
       //创建隐藏的可下载链接
        const blob = new Blob([res]);
        const link = document.createElement('a');
        const evt = document.createEvent('HTMLEvents');
        evt.initEvent('click', false, false);
        link.href = URL.createObjectURL(blob); //触发点击
        link.download = req.name + suffixName;
        link.style.display = 'none'; //字符内容转变成blob地址
        document.body.appendChild(link);
        link.click();//然后移除
          //释放内存
        window.URL.revokeObjectURL(link.href);
		document.body.removeChild(link );
      });
