Detect content type in a request made with cURL

Question

I am trying to send cURL request to a remote API server with this code:

$ch = curl_init(); $options = array(CURLOPT_URL => 'http://minecms.info/update/index.php', CURLOPT_POST => true, CURLOPT_RETURNTRANSFER => 1, CURLOPT_POSTFIELDS => $data, CURLOPT_HTTPHEADER => array('Content-type: application/json'), CURLOPT_SSL_VERIFYPEER => false ); curl_setopt_array($ch, $options); $response = curl_exec($ch);

But I don't want users accessing the updates page on their browsers so I set a content type header on the request. The problem is that I don't know how to detect this content type on the remote server. Basically what I want is to check whether the client request has a content type: application/json set if yes it executes the rest of the code if not it just does exit;.

Thank you to anyone who would help in advance.

There is no reliable cross-environment way to check headers received in php. If it's apache, try apache_request_headers(); — Anthony

@Anthony I am trying to make this an open source CMS so everyone runs it on different server and i would want it to be competible with all servers — Jordan Jones

You want the cms platform to be open-source or just have the cms server you are running be an open cms? If you want to write a new cms, then setting the content-type header is a really weak approach that anyone could bypass. — Anthony

You can try using getallheaders() and check whether the Content-Type is in place.

Give a look at the man http://www.php.net/manual/it/function.getallheaders.php for insights

---- EDIT INSIGHTS ----

And what about this one? (Which I'm currently using)

public function getAllHeaders() { if(function_exists('getallheaders')) { return getallheaders(); } $headers = array(); foreach ($this->parameters as $key => $value) { if (substr($key, 0, 5) == 'HTTP_') { $headers[str_replace(" ", "-", ucwords(strtolower(str_replace("_", " ", substr($key, 5)))))] = $value; } if ($key == "CONTENT_TYPE") { $headers["Content-Type"] = $value; } } return $headers; }
