搞到这段代码不容易，有时间仔细研究下
download(){
const url = "文件地址"
axios.get(url,{
responseType:'blob'
}).then( res => {
let blob = new Blob([res.data])
let downloadElement = document.createElement('a')
let href = window.URL.createObjectURL(blob); //创建下载的链接
downloadElement.href = href;
downloadElement.download = `new name`; //下载后文件名
document.body.appendChild(downloadElement);
downloadElement.click(); //点击下载
document.body.removeChild(downloadElement); //下载完成移除元素
window.URL.revokeObjectURL(href); //释放blob对象
})
}
