1.文件流下载文件: /** * @description: * @param {type} fileName-文件名 suffix-后缀名 * @return: */ export function axiosPostExport (url, data, fileName, suffix=\'.xlsx\') { url = getUrlIfUseMock(url, {method: \'POST\'}); return axios({ method: \'post\', url, data, responseType: \'blob\' }).then(res => { return res.data }).then(res => { const content = res const fileNamex = fileName + \'-\' + moment().format(\'YYYYMMDDHHmmss\') + suffix const blob = new Blob([content]) if (\'download\' in document.createElement(\'a\')) { // 非IE下载 const elink = document.createElement(\'a\') elink.download = fileNamex 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) } else { // IE10+下载 navigator.msSaveBlob(blob, fileNamex) } }).catch(error => console.log(error)) } 或者:let url = `/admin/user/list/all/export?countryCode=310101`; let xhr = new XMLHttpRequest(); xhr.open("POST", url, true); // 也可以使用POST方式,根据接口 xhr.responseType = "blob"; // 返回类型blob,XMLHttpRequest支持二进制流类型 xhr.onload = function() { if (this.status === 200) { let blob = this.response; //使用response作为返回,而非responseText let reader = new FileReader(); reader.readAsDataURL(blob); // 转换为base64,可以直接放入a标签href reader.onload = function(e) { // 转换完成,创建一个a标签用于下载 let a = document.createElement("a"); a.download = "原始数据.xls"; a.href = e.target.result; a.click(); }; } }; xhr.send("countryCode=310101"); 2.一般文件下载: <button class="layui-btn search" style="margin-left: 50px;" v-if="hash==2"><a href="/admin/user/list/all/export" download="userlist.xls" style="color: #fff;">导出</a></button> 3.与2实现效果差不多
var $form = $(\'<form method="post"></form>\'); $form.attr(\'action\', \'/admin/user/list/all/export?countryCode=310101\'); $form.appendTo($(\'body\')); $form.submit(); $form.remove();
4.直接open()打开url链接下载,这时候接口也是返回来的二进制的数据:
download(file){//下载文件
// console.log("fileL:",file);
const index = this.fileList1.indexOf(file);
const filedir=this.filedirList[index];
const that = this;
let url = `${this.urlDownload}?fileName=${file.name}&filedir=${filedir}`;
window.open(url);//下载文件
},
