CURL Post - Length required

Question

I've made a simple code to login to my website.

private function request($url, $reset_cookies, $post_data)
  {

    $options = array(
      CURLOPT_URL               => $url,
      CURLOPT_RETURNTRANSFER    => 1,
      CURLOPT_HEADER            => 0,
      CURLOPT_FAILONERROR       => 1,
      CURLOPT_USERAGENT         => $this->user_agent,
      CURLOPT_CONNECTTIMEOUT    => 30,
      CURLOPT_TIMEOUT           => 30,
      CURLOPT_SSL_VERIFYPEER    => 0,   
      CURLOPT_FOLLOWLOCATION    => 1,
      CURLOPT_MAXREDIRS         => 10,
      CURLOPT_AUTOREFERER       => 1,
      CURLOPT_COOKIESESSION     => $reset_cookies ? 1 : 0,
      CURLOPT_COOKIEJAR         => $this->session_id,
      CURLOPT_COOKIEFILE        => $this->session_id,
    );

    // Add POST data
    if (isset($post_data))
    {
      $options[CURLOPT_CUSTOMREQUEST] = 'POST';
      $options[CURLOPT_POST]          = 1;
      $options[CURLOPT_POSTFIELDS]    = http_build_query($post_data);
    }

    // Attach options
    curl_setopt_array($this->curl, $options);

    // Execute the request and read the response
    $content = curl_exec($this->curl);

    // Handle any error
    if (curl_errno($this->curl)) throw new Exception(curl_error($this->curl));

    return $content;
  }

So basically, a normal step for my login system would be:

1. Send a GET request to retrieve the security token and initialize a cookie session. (DONE and WORKING)

   $security_token = $this->browser->request('https://mysite.com/login', true, null);
   

2. Send a POST request with the username, the password and the security token.

   $postdata = array(
       'login' => $login,
       'password' => $password,
       '__RequestVerificationToken' => $security_token,
   );
   $login_page = $this->browser->request('https://mysite.com/login', false, $postdata);
   

On step #2, I got a 411 error saying the content length is required.

Did I make something wrong or did I forget to set a parameter ?

Answer 1

Solution was to remove this line

$options[CURLOPT_CUSTOMREQUEST] = 'POST';
