1.html
<el-button type="primary" @click.native="handleExport">下载</el-button>
2.修改axios请求的responseType为blob，以post请求为例
export function export(params) {
return axios({
headers: {
'Content-Type':'application/json'
},
responseType: 'blob', //一定要写
method: 'post',
url:'/export',
data:{
"head": {},
"body": {
"data":params
}
}
})
}
3.进行请求处理
handleExport() {
const params = {};
export(params).then(res => {
console.log(res.data)
const blob = new Blob([res.data]);//处理文档流
const fileName = 'excel.xlsx';
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); // 释放URL 对象
document.body.removeChild(elink);
});
},
