php - AMFPHP: Serializing Flash Objects over HTTP without the gateway -

flash + amfphp great combination. there cases, when flash remoting netconnection isn't right tool, various reasons. rob had great post on time ago: http://www.roboncode.com/articles/144

he has nice example on how deliver amf http request, without post , amf-request package call function netconnection sends, using zend_amf.

// include zend loader include_once 'zend/loader.php'; // tell zend loader autoload classes need // zend framework amf package zend_loader::registerautoload();  // create simple data structure $data = array('message' => 'hello, world!'); // create instance of amf output stream $out = new zend_amf_parse_outputstream(); // serialize our content amf3 example // alternatively serialize amf0 legacy // flash applications. $s = new zend_amf_parse_amf3_serializer($out); $s->writeobject($data);  // return content (we have found newline needed // in order process data correctly on client side) echo "\n" . $out->getstream(); 

i approach , hapy replicate amfphp. why amfphp, ask? 'newest' version uses amf-ext, c php extension, serialize , deserialize data. faster php way zendamf still using.

of course played around amfphp , tried build necessary objects , use serializer class. got valid amf string, real data wrapped 'method package' told receiver answer 'service.method' call.

so there way serialize flash objects directly, without gateway , method wrapper, in amfphp?

thanks.

okay, got work now.

it's little bit more complicated zend_amf solution, faster. here code:

$data = array('message' => 'hello, world!');  // create gateway , configure $amf = new gateway(); amf_server::$encoding = 'amf3'; amf_server::$disabledebug = true;  // construct body $body = new messagebody("...", "/1", array()); $body->setresults($data); $body->responseuri = $body->responseindex . "...";  // create object , add body $out = new amfobject(); $out->addbody($body);  // serializer , use $serializer = new amfsimpleserializer(); $result = $serializer->serialize($out); 

as see there new class amfsimpleserializer built:

class amfsimpleserializer extends amfserializer {     function serialize(&$amfout)     {         $encodecallback = array(&$this,"encodecallback");          $body = &$amfout->getbodyat(0);          $this->outbuffer = "";         $this->outbuffer .= amf_encode($body->getresults(), $this->encodeflags, $encodecallback);         $this->outbuffer = substr($this->outbuffer, 1);          return $this->outbuffer;     } } 

this class works if amfext installed, modded use php enocding process. didn't implement it, because built on heavily modified version of amfphp.

i hope replaced classes code there real amfphp counterparts. i'll try test tomorrow , update answer if necessary.

after finished recognized nothing amfphp left in class, it's call amf_encode , deletion of first byte client can understand gets.

easy, simple, fast.
