前端VUE頁面上的導出或者下載功能,通常是調用後端的一個接口,由接口生成excel,word這些文件的流信息,返回給vue,而後由vue去構建下載的動做,這邊整理了一下,封裝了一下,方便之後複用。前端
使用年月日時分秒毫秒作爲文件的名稱,下載爲excel文件vue
/** * 下載文件 */ export const downloadFile = (url,ext, params) => { let accessToken = getStore('accessToken'); return axios({ method: 'get', url: `${base}${url}`, params: params, headers: { 'accessToken': accessToken }, responseType: 'blob', //二進制流 }).then(res => { // 處理返回的文件流 const content = res; const blob = new Blob([content], { type: 'application/vnd.ms-excel;charset=utf-8' }); var date = new Date().getFullYear() + "" + (new Date().getMonth() + 1) + "" + new Date().getDate() + "" + new Date().getHours() + "" + new Date().getMinutes() + "" + new Date().getSeconds() + "" + new Date().getMilliseconds(); const fileName = date + "." + ext; if ("download" in document.createElement("a")) { // 非IE下載 const elink = document.createElement("a"); elink.download = fileName; elink.style.display = "none"; elink.href = URL.createObjectURL(blob); document.body.appendChild(elink); elink.click(); URL.revokeObjectURL(elink.href); // 釋放URL 對象 document.body.removeChild(elink); } else { // IE10+下載 navigator.msSaveBlob(blob, fileName); } }); };
// 評價導出 export const getRecordExport= (params) => { return downloadFile('/record/export',"xlsx", params) }
<script> import { getReportExport } from "@/api/index"; import util from "@/libs/util.js"; export default { name: "task-manage", data() {}, methods: { exportExcel() { getReportExport(this.searchForm).then(res=>{}); } } }
