vue中使用axios发送post请求实现excel下载

import { getToken } from '@/utils/auth.js'
import axios from 'axios'
axios.defaults.headers.post['Content-Type'] = 'multipart/form-data'
axios.create({ withCredentials: true, timeout: 5000 })
if (getToken()) { axios.defaults.headers.common['X-Token'] = getToken() }

 

axios({
        method: 'post',
        url: `/api/potentialCustomers/export`,
        responseType: 'blob',
        data: param
      }).then(res => {
        let fileName = res.headers['content-disposition'].split(';')[1].split('=')[1].replace(/\"/g, '')

        let blob = new Blob([res.data], { type: "application/vnd.ms-excel" })

        if ('msSaveOrOpenBlob' in navigator) {

          window.navigator.msSaveOrOpenBlob(blob, fileName);

        } else {

          const elink = document.createElement('a');

          elink.download = fileName;

          elink.style.display = 'none';

          elink.href = URL.createObjectURL(blob);

          document.body.appendChild(elink);

          elink.click();

          URL.revokeObjectURL(elink.href);

          document.body.removeChild(elink);

        }
      }).catch(res => {
        console.log(err)
      })
