vue axios导出xsl文件(二进制)

axios请求封装

function http(config) {
  // axios的默认配置 如果时get 参数需要放到 params
  // 如果是post 参数需要放到  data
  var myConfig = {
    url: config.url,
    method: config.method,
    header: {},
    responseType: config.responseType || ‘‘
  }
  if (config.method.toLowerCase() == ‘post‘) {
    myConfig.data = config.params
  } else if (config.method.toLowerCase() == ‘get‘) {
    myConfig.params = config.params
  }
  if (config.header) {
    myConfig.header = Object.assign(myConfig.header, config.header);
  }
  // 区分了get和post 的配置
  //service就是axios
  return service(myConfig)
}
export default http

接口封装

import request from ‘@/api/http‘
//导出老师信息
function exportTeachers(params) {
  return request({
    url: ‘/web/teacher/exportTeachers‘,
    method: ‘post‘,
    headers: { ‘content-type‘: ‘application/vnd.ms-excel;charset=utf-8‘ },
    responseType: ‘arraybuffer‘,
    params
  })
}
export default {
  exportTeachers
}

页面代码

exportTeachers() {
      let data = {
        schoolCode: this.schoolNumber,
        enrollmentYear: this.filterGradeTeacher.enrollmentYear || ‘‘,
        classId: this.filterClassTeacher.id || ‘‘
      }
      techerApi.exportTeachers(data).then(res => {
          //解析
        const url = window.URL.createObjectURL(new Blob([res]))
        const link = document.createElement(‘a‘)
        link.style.display = ‘none‘
        link.href = url
        link.setAttribute(‘download‘, `老师信息.xls`)
        document.body.appendChild(link)
        link.click()
      })
    },

注意:导出的xls文件内容一直为undefined,经过多次尝试需加上responseType: ‘arraybuffer‘才行,具体还是得根据后端.
