在vue中使用axios实现post方式获取二进制流下载文件(实例代码)

let blob = res.data
let reader = new FileReader()
reader.readAsDataURL(blob)
reader.onload = (e) => {
 let a = document.createElement('a')
 a.download = fileName
 a.href = e.target.result
 document.body.appendChild(a)
 a.click()
 document.body.removeChild(a)
}

response.setContentType("multipart/form-data");
response.setCharacterEncoding("utf-8");
response.setHeader("Content-disposition", "attachment;filename=" + UUID.randomUUID().toString() + ".xlsx");
response.setHeader("FileName", UUID.randomUUID().toString() + ".xlsx");
response.setHeader("Access-Control-Expose-Headers", "FileName")

axios.post({
 url:`url`,
 method:`post`,
 responseType: 'blob'
}).then(res => {
 let blob = res.data
 let reader = new FileReader()
 reader.readAsDataURL(blob)
 reader.onload = (e) => {
  let a = document.createElement('a')
  a.download = `fileName.xlsx`
  a.href = e.target.result
  document.body.appendChild(a)
  a.click()
  document.body.removeChild(a)
 }
})

import axios from 'axios';
Vue.prototype.axios = axios;

this.axios.post('http://ai.yiche.com/web/ability/nlu/standardTokenizer', {
     "text": "动效如果有跟评审结论有出入的地方或者不清楚的地方，随时沟通哈~"
    }).then(function(res) {
     console.log(res.data);
    }).catch(function(err) {
     if (err.response) {
      console.log(err.response)
     }
    });
