封装axios api 导出excel文件

function exportExcel(method, url, data, callback) {
    return new Promise((resolve, reject) => {
        let ajaxParams = {}
        ajaxParams = {
            method: method,

            },
            responseType: 'arraybuffer' // 表示服务器响应的数据类型，可以是 'arraybuffer', 'blob', 'document', 'json', 'text', 'stream'
        }
        instance(ajaxParams).then(res => {
            if(res.status == 200) {
                const content = res.data;
                const blob = new Blob([content], {type: 'application/vnd.ms-excel'});
                const elink = document.createElement('a');
                elink.download = `xx信息.xls`;
                elink.style.display = 'none';
                elink.href = URL.createObjectURL(blob);
                document.body.appendChild(elink);
                elink.click();
                URL.revokeObjectURL(elink.href); // 释放URL 对象
