API - Chunked File Upload OAuth Error

The Archives Help Topics
1

I am trying to upload chunked files via the API. I have read several post about this but there does not seem to be a straight forward solution yet.

The problem code I have:

$fileName = (FILE PATH HERE);

set_time_limit(0);
$file = fopen($fileName,"rb");
$chunkedFile = '';
while(!feof($file))
{
	$chunkedFile .= fread($file, 1024);
}
fclose($file);
$payload = base64_encode($chunkedFile);	

$params = array(
        'service' => 'rest',
        'method' => 'LibraryMediaFileUpload',
        'response' => RESPONSE,
        'fileId' => NULL,
        'checksum' => md5($payload),
        'payload' => $payload
    );
callService($params, true);

Produces this when the file is larger than the first chunk size:

( ! ) Fatal error: Uncaught exception ‘OAuthException2’ with message ‘Request failed with code 500: {“file”:{“id”:“863”,“offset”:5510872}}’ in C:\wamp\www\xibo_interface_beta\oauth-php\library\OAuthRequester.php on line 117

Any idea what exactly this error is telling me would be helpful.

I don’t believe the problem is within Xibo.

But I if anyone knows, maybe, why I am getting the error or how to get more info about it, feel free to comment.

Line 117 is:

throw new OAuthException2('Request failed with code ' . $result['code'] . ': ' . $result['body']);

In the following function of OAuthRequester.php:

function doRequest ( $usr_id = 0, $curl_options = array(CURLOPT_SSL_VERIFYPEER => 0, ), $options = array() )
{
	$name = isset($options['name']) ? $options['name'] : '';
	if (isset($options['token_ttl']))
	{
		$this->setParam('xoauth_token_ttl', intval($options['token_ttl']));
	}

	if (!empty($this->files))
	{
		// At the moment OAuth does not support multipart/form-data, so try to encode
		// the supplied file (or data) as the request body and add a content-disposition header.
		list($extra_headers, $body) = OAuthBodyContentDisposition::encodeBody($this->files);
		$this->setBody($body);
		$curl_options = $this->prepareCurlOptions($curl_options, $extra_headers);
	}
	$this->sign($usr_id, null, $name);
	$text   = $this->curl_raw($curl_options);
	$result = $this->curl_parse($text);	
	if ($result['code'] >= 400)
	{
		throw new OAuthException2('Request failed with code ' . $result['code'] . ': ' . $result['body']);
	}

	// Record the token time to live for this server access token, immediate delete iff ttl <= 0
	// Only done on a succesful request.	
	$token_ttl = $this->getParam('xoauth_token_ttl', false);
	if (is_numeric($token_ttl))
	{
		$this->store->setServerTokenTtl($this->getParam('oauth_consumer_key',true), $this->getParam('oauth_token',true), $token_ttl);
	}

	return $result;
}

If I swap “throw” for “echo” online 117 the file uploads correctly and everything continues. But of course I get the error echoed to the screen:
