vue 这种流数据如何获取？

控制台打印的response：但是我却获取不到这个data，断点打印的res是个空对象公共方法：

export const createExcel = (res, name) => {
  let blob = new Blob([res], {
    type: 'application/vnd.ms-excel',
  });
  let fileName = name + '.xlsx'; // 文件名+后缀
  // 允许用户在客户端上保存文件
  if (window.navigator.msSaveOrOpenBlob) {
    navigator.msSaveBlob(blob, fileName);
  } else {
    // eslint-disable-next-line no-debugger
    debugger;
    var link = document.createElement('a'); //定义一个a标签
    link.href = window.URL.createObjectURL(blob); //需要生成一个 URL 来实现下载，链接到blob上
    link.download = fileName; //下载后的文件名称
    console.log('fileName', link);
    link.click(); //模拟在按钮上实现一次鼠标点击
    window.URL.revokeObjectURL(link.href); //释放 URL 对象
  }
};

页面调用

getOrganExport({ parentId: this.nodeId })
          .then((res) => {
            console.log('res----', res);
            createExcel(res, '组织管理表');
            this.$message.success('导出成功');
          })
          .catch(() => {
            this.$message.error('导出失败，请稍后再试');
          });

service封装：

import axios from 'axios';
import qs from 'qs';
import { Message } from '@jdt/find';
// import Cookies from 'js-cookie';

const defaultOptions = {
  baseURL: '/api',
  method: 'post', // 请求 type  get post delete header put
  withCredentials: true, // 设置该属性可以把 cookie 信息传到后台
  headers: {
    Accept: 'application/json',
    'Content-Type': 'application/json; charset=utf-8',
  },
};

const http = axios.create(defaultOptions);

http.interceptors.request.use(
  (config) => {
    // 在发送请求之前做些什么
    const { method, data, headers, baseURL } = config;
    // 如果参数中有baseURL‘，更新默认baseURL
    if (baseURL && baseURL === process.env.VUE_APP_BASE_URL) http.baseURL = baseURL;

    if (method !== 'get' && method !== 'head') {
      if (data instanceof FormData) {
        config.data = data;
        // config.headers = {
        //   ...headers,
        //   'x-requested-with': 'XMLHttpRequest',
        //   'cache-control': 'no-cache',
        // };
        delete config.headers;
      } else if (headers['Content-Type'] === 'application/x-www-form-urlencoded') {
        config.data = qs.stringify(data);
      } else {
        // 是否需要去除无用数据
        // Object.keys(data).forEach((item) => {
        //   if (data[item] === null || data[item] === undefined || data[item] === '') {
        //     delete data[item];
        //   }
        // });
        config.data = JSON.stringify(data);
      }
    }
    if (method === 'get') {
      config.paramsSerializer = function (params) {
        return qs.stringify(params, {
          arrayFormat: 'indices',
        });
      };
    }
    return config;
  },
  (error) => {
    // 对请求错误做些什么
    return Promise.reject(error);
  }
);

http.interceptors.response.use(
  (response) => {
    console.log(response);
    const { data: { data, status = true, error = {} } = {} } = response;
    if (!status) {
      const msg = error.msg || '服务端执行出错！';
      if (error.code === 'REL001') {
        return Promise.reject(msg);
      } else {
        Message.error(msg);
      }
      return Promise.reject(msg);
    }
    return data || {};
  },
  (error) => {
    if (error.response) {
      // The request was made and the server responded with a status code
      // that falls out of the range of 2xx
      const { status: responseStatus } = error.response;
      if (responseStatus === 401) {
        // 记录当前跳出登录地址，登录成功后跳回来
        // Cookies.set('origin_url', window.location.href);
        // window.location = '/login';
      } else if (responseStatus === 403) {
        // 没有权限
        Message.error('没有权限操作！');
      } else {
        const msg = error.response?.data?.error?.msg || '服务端接口异常！';
        Message.error(msg);
        return Promise.reject(new Error(msg));
      }
    } else {
      // Something happened in setting up the request that triggered an Error
      console.error(error);
      return Promise.reject(new Error('请求出错！'));
    }
    return Promise.reject(error);
  }
);

export default http;
