Making post request with Symfony 3? - php

Question

I have a function in Symfony3 that posts data to a mysql database. The function looks like this:
/**
* #Route("/LegoPieces")
* #METHOD("POST")
* #View()
*
* #Annotations\QueryParam(
* name="piece", nullable=false, description="piece"
* )
* #Annotations\QueryParam(
* name="type", nullable=false, description="type"
* )
* #Annotations\QueryParam(
* name="startDate", nullable=false, description="Start Date YYYY-MM-DD HH:MM:SS (Should be in the future)"
* )
* #Annotations\QueryParam(
* name="endDate", nullable=false, description="End Date YYYY-MM-DD HH:MM:SS (Should be no more than 3 weeks in the future)"
* )
*/
public function postAction(ParamFetcherInterface $paramFetcher)
{
$piece = $paramFetcher->get('piece');
$type = $paramFetcher->get('type');
$start = $paramFetcher->get('startDate');
$end = $paramFetcher->get('endDate');
$startDate = DateTime::createFromFormat('Y-m-d H:i:s', $start);
$endDate = DateTime::createFromFormat(' Y-m-d H:i:s', $end);
$em = $this->getDoctrine()->getManager('default');
$data = new LegoPieces();
$data->setPiece($piece);
$data->setType($type);
$data->setStartDate($startDate);
$data->setEndDate($endDate);
$em->persist($data);
$em->flush();
return new JsonResponse("LegoPieces Added Successfully", 200);
}
When I replace the variables ($piece, $type, $startDate, $endDate) with strings the post request works. But when I try to make a post request through something like Postman or javascript like this:
fetch("http://localhost:8000/LegoPieces", {
method: "POST",
body: {
startDate: this.startDate,
endDate: this.endDate,
piece: this.piece,
type: this.type
}
}).then(response => response.json())
);
});
I get a 500 error! I don't understand- thanks for your help!

Answer 1

Look in your logs what is your error.
But you have to improve your controller ! You don't use Symfony Form and you don't have any validations. Even if your haven't 500 error now, you will have some in the future if you don't respect your entity types.
I also don't understand why you use a post request and don't pass all your parameters in your body. You only use get parameters in the url.

Answer 2

Without knowing what exception makes that 500 - you know nothing :(
Try to see response body
Without that info - i have only one idea .
If you arw working on dev envionment , then youur js request simply may not see routes (and the other stuff)
clear all contents of cache folder
rm -rf var/cache/*
and
php bin/console c:w -e prod
