1.文件流下载文件
axios实现:
export function download(url, data){
axios.post(baseurl+url,data,{responseType: 'blob'})
.then(function (response) {
var filename = response.headers//下载后文件名
filename = filename["content-disposition"]
filename = filename.split(";")[1].split("filename=")[1];
var blob = new Blob([response.data])
var downloadElement = document.createElement('a');
var href = window.URL.createObjectURL(blob); //创建下载的链接
downloadElement.href = href;
downloadElement.download = filename
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); //释放掉blob对象
})
.catch(function (error) {
console.log("File download error!")
})
}
注意,想要获取headers中content-disposition的数据,服务端要加一个:
response.setHeader("Access-Control-Expose-Headers","Content-Disposition");
