本文实例讲述了PHP使用ajax的post方式下载excel文件。分享给大家供大家参考,具体如下:
项目需求,前端发起ajax请求,后端生成excel并下载,同时需要在header头中,带上token验证信息,参考了很多文章,最终实现如下:
PHP后端使用base64:

$filename = 'demo.xlsx' ;
$objWriter = \PHPExcel_IOFactory::createWriter( $objectPHPExcel , 'Excel2007' );
ob_start();
$objWriter ->save( "php://output" );
$xlsData = ob_get_contents();
ob_end_clean();
return Api::success([ 'filename' => $filename , 'file' => "data:application/vnd.ms-excel;base64," . base64_encode ( $xlsData )]);

$( '.download' ).click( function (){
var url = "http://xxxx.com/group/bi/export" ;
var params = {
from_date: '2017-09-01' ,
to_date: '2017-09-08' ,
group_id: 1
};
$.ajax({
type: 'POST' ,
url: url,
data: params,
beforeSend: function (request) {
request.setRequestHeader( "Authorization" , "token信息,验证身份" );
},
success: function (redata) {
// 创建a标签,设置属性,并触发点击下载
var $a = $( "<a>" );
$a.attr( "href" , redata.data.file);
$a.attr( "download" , redata.data.filename);
$( "body" ).append($a);
$a[0].click();
$a.remove();
}
});
});
