前端vue页面上的导出或者下载功能,一般是调用后端的一个接口,由接口生成excel,word这些文件的流信息,返回给vue,然后由vue去构建下载的动作,这边整理了一下,封装了一下,方便以后复用。
使用年月日时分秒毫秒做为文件的名称,下载为excel文件
/**
* 下载文件
*/
export const downloadFile = (url,ext, params) => {
let accessToken = getStore(‘accessToken‘);
return axios({
method: ‘get‘,
url: `${base}${url}`,
params: params,
headers: {
‘accessToken‘: accessToken
},
responseType: ‘blob‘, //二进制流
}).then(res => {
// 处理返回的文件流
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下载
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); // 释放URL 对象
document.body.removeChild(elink);
} else {
// IE10+下载
navigator.msSaveBlob(blob, fileName);
}
});
};
// 评价导出
export const getRecordExport= (params) => {
return downloadFile(‘/record/export‘,"xlsx", params)
}
