KernelBrowser adding params to body POST request - php

Question

I'm trying to test an endpoint of my Api with phpunit and the symfony WebTestCase object. I have to send a POST request with the KernelBrowser but I can't figure it out how to add parameters to the body of the request. My request work fine on postman.
I've tried this
$client->request('POST', '/url', ['param1' =>'value1', 'param2' => 'value2']);
It's not working.
I've tried this
$client->request('POST', '/url', [], [], [], '{param1: value, param2: value}');
It doesn't work,
I can't use the $client->submitForm() method because the form is send by another app.
Maybe it came from my Api endpoint because I'm using $_POST variable ?:
$res = false;
if(count($_POST) === 2){
$user = $this->userrepo->findByName($_POST['value1']);
if($user){
if($this->passwordEncoder->isPasswordValid($user[0], $_POST['value2'])){
$res = true;
}
}
}
return new Response($this->serializer->serialize(['isChecked' => $res], 'json'));
My test method has never passed the first if statement,
here my test method:
$client = static::createClient();
$client->request('POST', '/url', ['value1' => 'value1', 'value2' => 'value2']);
$this->assertStringContainsString('{"isChecked":true}', $client->getResponse()->getContent());
Here the POST request I'm trying to send:
curl --location --request POST 'http://localhost:8000/url' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--form 'value1=value1' \
--form 'value2=value2'

Symfony's test client dispatches the request internally. The global $_POST variable will always be empty. You should use the Request object in the controller to access the parameters. The attribute request contains the post data.
public function myAction(Request $request): Response
{
$postParameters = $request->request;
$res = false;
if ($postParameters->count() === 2) {
$user = $this->userrepo->findByName($postParameters->get('value1'));
if ($user) {
if ($this->passwordEncoder->isPasswordValid($user[0], $postParameters->get('value2'))) {
$res = true;
}
}
}
return new Response($this->serializer->serialize(['isChecked' => $res], 'json'));
}
Regarding the different variations of your test call, this one should work with the action above.
$client->request('POST', '/url', ['value1' => 'value1', 'value2' => 'value2']);
