11.前台文件数据流下载获取源文件名

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 = https://www.it610.com/article/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!") }) }

【11.前台文件数据流下载获取源文件名】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");
