How to get cURL JSON array only in ZF2 - php

Question

I am using ZF2 and curl for connecting with one of my clients API.
For example I am getting the response as
HTTP/1.1 200 OK Access-Control-Allow-Origin: * Content-Type: application/json; charset=ISO-8859-1 Date: Thu, 04 Dec 2014 06:12:13 GMT Server: Google Frontend Cache-Control: private Alternate-Protocol: 80:quic,p=0.02,80:quic,p=0.02 Connection: close { "time": "06:12:13 AM", "milliseconds_since_epoch": 1417673533861, "date": "12-04-2014" }
I need the JSON array only.
My code is:
$data = "";
$adapter = new Curl();
$client = new Client();
$client->setAdapter($adapter);
$client->setUri('http://date.jsontest.com');
$client->setMethod('POST');
$adapter->setCurlOption(CURLOPT_POST, 1);
$adapter->setCurlOption(CURLOPT_POSTFIELDS, $data);
$adapter->setCurlOption(CURLOPT_SSL_VERIFYPEER, 0);
$adapter->setCurlOption(CURLOPT_HTTPHEADER, array(
'Content-type: application/json',
'Authorization: Bearer $token'
));
$response = $client->send();
return new ViewModel(array(
'response' => $response,
));

The send() method of the Zend HTTP Client returns a new Response instance after successfully complete the request. You're directly passing that response instance to your view, not the content (body) inside the response.
Try this:
// Your current code..
$response = $client->send();
$viewModel = new ViewModel();
if($response->getStatusCode() === 200) {
$obj = json_decode($response->getBody(), true);
if($obj === null) {
// Json cannot be decoded.. handle it..
}
$viewModel->setVariable('response', $obj);
} else {
// Status code is not 200, handle it..
}
// And return the model
return $viewModel;
Not perfect but it should work..
