后端返回数据格式:
![image]()
重新定义一个api
import axios from 'axios'
export function exportFun(data) {
    axios({
        method: data.method,
		url:data.url,
		params:data.params,
        data:data.data,
        responseType: 'blob',
    }).then((res) => {
        const link = document.createElement('a')
        let blob = new Blob([res.data], {type: 'application/vnd.ms-excel'})
        link.style.display = 'none'
        link.href = URL.createObjectURL(blob)
		let fullName=res.headers['content-disposition'].split('=')
        link.download = data.fileName|| fullName[fullName.length-1]//下载后文件名
        document.body.appendChild(link)
        link.click()
        document.body.removeChild(link)
    }).catch(error => {
        console.log(error)
    })
}
使用
exportMethod({
	method: 'post',
	url: 'url',
	params:this.excelForm,
	fileName:`hello.xlsx`
})```
