vue2文件数据不多可以直接下载不需要后端的时候
1.首先，确保你已经安装了 docx 和 file-saver 库
npm install file-savernpm install docx file-saver
2.全部代码如下

vue2数据很多的时候需要后端
<a-button type="primary" style="margin-left: 8px" @click="getExport">下载导入模板</a-button>import { downloadFile } from "@/api/manage"; 
api/manage代码如下
// import { axios } from '@/utils/request'
import axios from "@/utils/axios";
import signMd5Utils from "@/utils/encryption/signMd5Utils";const api = {user: "/mock/api/user",role: "/mock/api/role",service: "/mock/api/service",permission: "/mock/api/permission",permissionNoPager: "/mock/api/permission/no-pager",
};export default api;//post
export function postAction(url, parameter) {let sign = signMd5Utils.getSign(url, parameter);//将签名和时间戳，添加在请求接口 Headerlet signHeader = {"X-Sign": sign,"X-TIMESTAMP": signMd5Utils.getDateTimeToString(),};return axios({url: url,method: "post",data: parameter,headers: signHeader,});
}//post method= {post | put}
export function httpAction(url, parameter, method) {let sign = signMd5Utils.getSign(url, parameter);//将签名和时间戳，添加在请求接口 Headerlet signHeader = {"X-Sign": sign,"X-TIMESTAMP": signMd5Utils.getDateTimeToString(),};return axios({url: url,method: method,data: parameter,headers: signHeader,});
}//put
export function putAction(url, parameter) {return axios({url: url,method: "put",data: parameter,});
}//get
export function getAction(url, parameter) {let sign = signMd5Utils.getSign(url, parameter);//将签名和时间戳，添加在请求接口 Headerlet signHeader = {"X-Sign": sign,"X-TIMESTAMP": signMd5Utils.getDateTimeToString(),};return axios({url: url,method: "get",params: parameter,headers: signHeader,});
}//deleteAction
export function deleteAction(url, parameter) {return axios({url: url,method: "delete",params: parameter,});
}export function getUserList(parameter) {return axios({url: api.user,method: "get",params: parameter,});
}export function getRoleList(parameter) {return axios({url: api.role,method: "get",params: parameter,});
}export function getServiceList(parameter) {return axios({url: api.service,method: "get",params: parameter,});
}export function getPermissions(parameter) {return axios({url: api.permissionNoPager,method: "get",params: parameter,});
}// id == 0 add post
// id != 0 update put
export function saveService(parameter) {return axios({url: api.service,method: parameter.id == 0 ? "post" : "put",data: parameter,});
}/*** 下载文件 用于excel导出* @param url* @param parameter* @returns {*}*/
export function downFile(url, parameter, method) {return axios({url: url,params: parameter,method: method ? method : "get",responseType: "blob",});
}/*** 下载文件* @param url 文件路径* @param fileName 文件名* @param parameter* @returns {*}*/
export function downloadFile(url, fileName, parameter,method) {return downFile(url, parameter,method).then((data) => {// if (!data || data.size === 0) {// Vue.prototype['$message'].warning('文件下载失败')// return// }if (typeof window.navigator.msSaveBlob !== "undefined") {window.navigator.msSaveBlob(new Blob([data]), fileName);} else {let url = window.URL.createObjectURL(new Blob([data]));let link = document.createElement("a");link.style.display = "none";link.href = url;link.setAttribute("download", fileName);document.body.appendChild(link);link.click();document.body.removeChild(link); //下载完成移除元素window.URL.revokeObjectURL(url); //释放掉blob对象}});
}/*** 文件上传 用于富文本上传图片* @param url* @param parameter* @returns {*}*/
export function uploadAction(url, parameter) {return axios({url: url,data: parameter,method: "post",headers: {"Content-Type": "multipart/form-data", // 文件上传},});
}/*** 获取文件服务访问路径* @param avatar* @param subStr* @returns {*}*/
export function getFileAccessHttpUrl(avatar, subStr) {if (!subStr) subStr = "http";try {if (avatar && avatar.startsWith(subStr)) {return avatar;} else {if (avatar && avatar.length > 0 && avatar.indexOf("[") == -1) {return window._CONFIG["staticDomainURL"] + "/" + avatar;}}} catch (err) {return;}
}
//导出模板getExport() {downloadFile("/asset/entryrecord/exportTemplateXls","财务信息模板.xlsx",{},"post");},合计
效果如图
