前端处理后端返回的文件流做导出操作

import { post } from 'axios';

// 导出

exportNoticeData() {

post(

'/safetyjapi/pic/gateWay/noticeExport',

{ ...this.entNameParams },

{

responseType: 'blob',

}

)

.then(res => {

if (res.status === 200) {

const blob = new Blob([res.data], {

type: 'application/ms-excel',

});

const reader = new FileReader();

reader.readAsDataURL(blob);

reader.onload = e => {

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

a.download = '公告栏.xls';

a.href = e.target.result;

document.body.appendChild(a);

a.click();

document.body.removeChild(a);

};

}

})

.catch(err => {

console.log(err.message);

});

},
