Сегодня я столкнулся с проблемой создания PDF с помощью KnpSnappyBundle на symfony.
Я запускаю маршрут с использованием AJAX, код работает нормально, но не создает PDF,
Здесь я хочу создать PDF-файл в новой вкладке или окне и вернуть клиенту успешное сообщение.
Вот мой код:
/**
* @Route("/api/release_bills/{month}/{year}/{region}", name="api_print_bills", methods={"GET","POST"})
* @param BillRepository $billRepository
* @param ConsumptionRepository $consumptionRepository
* @param Request $request
* @param Snappy $snappy
* @param $month
* @param $year
* @param $region
* @return Response
* @throws Exception
*/
public function releaseBills(BillRepository $billRepository,ConsumptionRepository $consumptionRepository, Request $request, Snappy $snappy, $month,$year,$region ): Response
{
$error = array();
$success = array();
if( $month>0 && $month<13 || preg_match("/^\d{4}$/",$year)||$region!=''){
if($year>=2018 && $year <=2050){
$entityManager = $this->getDoctrine()->getManager();
$bills = $consumptionRepository->findAllWaterMetersForBilling($month,$year,$region);
$isBillsExisted = $billRepository->findAllBillsByDate($month,$year,$region);
if(empty($bills)){
array_push($error,['error'=>'there is not bills to be release for this criteria : [ city: '.$region.', year :'.$year.', and Month : '.$month.'!]']);
return new JsonResponse($error);
}
$arr = array();
$newBills = array();
$billsEnd=end($bills);
foreach ($bills as $key=>$b){
$wmNumber = $b->getWaterMeter()->getWmNumber();
$fullName = $b->getWaterMeter()->getClient()->getFullName();
$cin = $b->getWaterMeter()->getClient()->getCin();
$address= $b->getWaterMeter()->getAddress();
$wmAddress = $b->getWaterMeter()->getAddress()->getStreetAddress();
$city = $b->getWaterMeter()->getAddress()->getCity();
$zipCode = $b->getWaterMeter()->getAddress()->getZipCode();
$billCode = $b->getId();
$consumptionDate = $b->getDate();
$oldConsumption=$b->getPreviousRecord();
$newConsumption=$b->getCurrentRecord();
$printDate =new \DateTime('now');
$consumption=$b->getConsumption();
$cost = $b->getCost()+10;
$wmReferenceNumber = $b->getWaterMeter()->getWmReferenceNumber();
$client= $b->getWaterMeter()->getClient();
// tranche calculation
//==================================================
$tranche1 = $consumption >= 5 ? 5 : $consumption; //4
$tranche2 = $consumption - $tranche1 >= 5 ? 5: 0; //0
$tranche3 = $consumption - $tranche1 - $tranche2;
//==================================================
$bill = new Bill();
$bill->setCode($wmNumber);
$bill->setFullName($fullName);
$bill->setCin($cin);
$bill->setPrintDate($printDate);
$bill->setCost($cost);
$bill->setConsumption($consumption);
$bill->setConsumptionDate($consumptionDate);
$bill->setPreviousRecord($oldConsumption);
$bill->setNewRecord($newConsumption);
$bill->setWaterMeter($b->getWaterMeter());
$bill->setRegion($city);
$bill->setClient($client);
$entityManager->persist($bill);
array_push($arr,['wmAddress'=>$wmAddress,'city'=>$city,'zipCode'=>$zipCode,'tranche1'=>$tranche1,'wmNumber'=>$wmNumber,'fullName'=>$fullName,'cin'=>$cin,'address'=>strval($address),'billCode'=>$billCode,'consumptionDate'=>$consumptionDate,'oldConsumption'=>$oldConsumption,'newConsumption'=>$newConsumption,'printDate'=>$printDate,'consumption'=>$consumption,'cost'=>$cost,'wmReferenceNumber'=>$wmReferenceNumber]);
if(count($arr)==6||$billCode==$billsEnd->getId()){
array_push($newBills,$arr);
$arr = array();
}
}
$date = new \DateTime('now');
$html= $this->renderView('bill/bill.html.twig', array(
'arrayBills'=>$newBills,
));
if($isBillsExisted){
return new PdfResponse(
$snappy->getOutputFromHtml($html), "bill_".$date->format('Y-m-d').".pdf"
);
}
$entityManager->flush(); //Persist objects that did not make up an entire batch
$entityManager->clear();
return new PdfResponse(
$snappy->getOutputFromHtml($html), "bill_".$date->format('Y-m-d').".pdf"
);
}
}
array_push($success,['success'=>'bills were successfully released']);
return new JsonResponse($success);
}
И мой вызов AJAX:
generatePDF = () =>{
const {yearValue, monthValue, regionValue}= this.state;
$.ajax({
url: `http://symfony.localhost/bill/api/release_bills/${monthValue.value}/${yearValue.value}/${regionValue.value}`,
success: function (data) {
console.log('DATA',data)
}.bind(this)
});
};
Я считаю, что я не могу вернуть более одного ответа, в любом случае я сделал журнал консоли, чтобы ответ на вызов ajax отображал HTML-содержимое страницы, из которой я хочу создать PDF, и PDF не создается.
