How to pass JSON data to rest API in symfony2 - php

Question

I am creating rest api for symfony 2,but not able to pass JSON data to post method. $userform->isValid()always failed.
curl -v -H "Accept: application/json" -X POST -d '{"username":"hitesh","userpassword":"hitesh123"}' http://localhost/us/serenify/web/app_dev.php/user/login
This is the data I am passing for test purpose.
public function loginAction(Request $request)
{
return $this->processForm(new User(),$request);
}
private function processForm(User $user,$request)
{
$userform = $this->createForm(new UserType(), $user);
$content = $this->getRequest();
$userform->submit($content);
$key = md5(microtime().rand());
if ($userform->isValid())
{
if(trim($data['username'])=="" || trim($data['userpassword']==""))
{
$data=array(
"success"=>'false',
"msg"=>'username or password is blank'
);
$response = new Response(json_encode($data));
$response->setStatusCode(203);
$response->headers->set('Content-Type', 'application/json');
}
else
{
$username=trim($data['username']);
$userpassword=trim(md5($data['userpassword']));
$user = $this->getDoctrine()
->getRepository('SerenifyUserBundle:User')
->findOneBy(array('username' => $username, 'userpassword' => $userpassword));
if (!$user)
{
$data=array(
"success"=>'false',
"msg"=>'username or password is wrong'
);
$response = new Response(json_encode($data));
$response->setStatusCode(404);
$response->headers->set('Content-Type', 'application/json');
}
else
{
$data=array(
"success"=>'true',
"msg"=>'user has sucessfully logged in',
"username" => $username,
"sessionis" => $key,
);
$response = new Response(json_encode($data));
$response->setStatusCode(404);
$response->headers->set('Content-Type', 'application/json');
}
$response = new Response(json_encode($data));
}
}
else
{
$data=array(
"success"=>'false',
"msg"=>'invalid form content'
);
$response = new Response(json_encode($data));
$response->setStatusCode(404);
$response->headers->set('Content-Type', 'application/json');
}
return $response;
}
Above is my controller code.
When I print request value is does not show in JSON format.
Anyway to test or pass JSON data? I am creating login functionality.

FOSRestBundle was created for these purposes. And I think you should start to use it in your project. It has no overhead and is easy to use.

Answer 2

I recently have had a need to something like this as I am extensively using AngularJS whose $http service sends data as JSON to my controllers.
I found a solution by implementing service which listens to incoming requests unpacks JSON and exposes it to Request object.
Check "The right way" section of this link.
