Error receiving bytes messages #28
Description
I was having problems receiving bytes messages for use with googles / chobies protocolbuffers php implementation with this STOMP implementation. Sending to a Java client worked like a charm, but the return to PHP failed trying to deserialize the protocol buffer bytes.
When executing $msg = $con->readFrame, it truncated the bytes by doing a trim on the message body removing all whitespace. The solution is the following new function for Stomp.php, whatch this line only stripping "\x00" instead of all whitespace :
$frame = new StompFrame($command, $headers, trim($body, "\x00"));
/**
* Read response frame from server for binairy messages
*
* @return StompFrame False when no frame to read
*/
public function readFrameBinairy ()
{
if (!$this->hasFrameToRead()) {
return false;
}
$rb = 1024;
$data = '';
$end = false;
do {
$read = fread($this->_socket, $rb);
if ($read === false) {
$this->_reconnect();
return $this->readFrame();
}
$data .= $read;
if (strpos($data, "\x00") !== false) {
$end = true;
$data = rtrim($data, "\n");
}
$len = strlen($data);
} while ($len < 2 || $end == false);
list ($header, $body) = explode("\n\n", $data, 2);
$header = explode("\n", $header);
$headers = array();
$command = null;
foreach ($header as $v) {
if (isset($command)) {
list ($name, $value) = explode(':', $v, 2);
$headers[$name] = $value;
} else {
$command = $v;
}
}
$frame = new StompFrame($command, $headers, trim($body, "\x00"));
if (isset($frame->headers['transformation']) && $frame->headers['transformation'] == 'jms-map-json') {
require_once 'Stomp/Map.php';
return new StompMessageMap($frame);
} else {
return $frame;
}
return $frame;
}
Thanks to my colleague Jan Grävell for his excelent PHP knowlledge.
