检测使用cURL发出的请求中的内容类型

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.

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

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;
}
