我正在使用Larevel（PHP Framework）并集成了Jasper API用于报告。它适用于小型报告，通常需要不到60秒的时间来处理。但是jasper会为大型报告抛出500内部错误，这通常需要2-3分钟的处理时间才能完成。当我在Jasper面板上运行相同的报告时，它可以工作，但它会从API调用向Laravel抛出错误（代码500）。
PHP设置： - memory_limit：512M，post_max_size：400M，upload_max_filesize：300M，max_execution_time：600
$.ajax({
type: "POST",
url: base_url+'admin/get-report-details',
data: $('form#jsperReports').serialize(),
dataType:'json',
timeout:1200000,
beforeSend: function(){
$('#reportDetailsRow').addClass('hide');
var dialog = bootbox.dialog({
message: '<p class="text-center">Please wait while we do something...</p>',
closeButton: false
});
},
success:function(data){
$('.modal').modal('hide');
if(!!data && data.success == true){
$('#reportDetails').html(data.html);
$('#reportDetailsRow').removeClass('hide');
}else if (!!data && data.success == false) {
showMsgModel("Error",data.msg)
}
}
});

我是否缺少任何配置，或者在从Laravel对Jasper进行API调用时是否需要进行任何其他设置？
