vue接收IO流 并写入Execl

代码块：

// 导出 js 注意(responseType: 'blob')
export function exportsmsRecordDetailList (query) {
    return request({
      url: '/exportsmsRecordDetailList',
      method: 'get',
      params: query,
      responseType: 'blob',
    })
  }
 // 导出  页面方法
    exportBtn() {
       let url = ''
       exportsmsRecordDetailList().then(res =>{
          const blob = new Blob([res]);
          const fileName = '发送记录.xls';
          const elink = document.createElement('a');// 创建a标签
          elink.download = fileName;// 为a标签添加download属性
          // a.download = fileName; //命名下载名称
          elink.style.display = 'none';
          elink.href = URL.createObjectURL(blob);
          document.body.appendChild(elink);
          elink.click();// 点击下载
          URL.revokeObjectURL(elink.href); // 释放URL 对象
          document.body.removeChild(elink);// 释放标签
          this.loadingExt = false;

       });
