将后端返回的二进制流文件 导出为excel表
用的时候直接调用showConfirm函数即可
最后效果
export function getExport(param) {
get('/api/xdata/v1/basic/auth/excel', { ...param }).then((res) => {
// let name = getFileName(url);
let name = 'export.xlsx';
console.log('res', res);
// let u = window.URL.createObjectURL(new Blob([res]));
const type = 'application/vnd.ms-excel;charset=utf-8'; //excel文件
let u = window.URL.createObjectURL(new Blob([res], { type: type }));
let a = document.createElement('a');
a.download = name;
a.href = u;
console.log(a);
a.style.display = 'none';
document.body.appendChild(a);
a.click();
a.remove();
// setTimeout(myDlWarn, 0);
});
}
export function showConfirm(text, exportParams) {
confirm({
title: `您确认要导出${text}吗`,
icon: <ExclamationCircleOutlined />,
content: '',
okText: '确认',
okType: 'primary',
cancelText: '取消',
onOk() {
getExport(exportParams);
},
onCancel() {
console.log('Cancel');
},
});
}
get接口是自己封装的,封装如下
/**
* 从 cookie 中获取数据
* @param {string} cname cname
*/
export const getCookie = (cname) => {
var name = cname + '=';
var ca = document.cookie.split(';');
for (var i = 0; i < ca.length; i++) {
var c = ca[i].trim();
if (c.indexOf(name) === 0) {
return c.substring(name.length, c.length);
}
}
return '';
};
