前端导出excel代码

// res为后端传递的数据
const blob = new Blob([res], {
          type: "application/ms-excel",
        });
        const elink = document.createElement("a");
        elink.download = "文件名.xls";
        elink.style.display = "none";
        elink.href = URL.createObjectURL(blob);
        document.body.appendChild(elink);
        elink.click();
        URL.revokeObjectURL(elink.href); // 释放URL对象
        document.body.removeChild(elink);

发送请求时需要设置responseType: 'blob', 不然打开的excel会有乱码
