I'm having problems sending a ByteArray over to my Zend_Amf_server. I get a NetConnection.Bad.Call back from the server. If I send a variable with another datatype then ByteArray it works fine.
I used the same script before with AMFPHP witouth any problems. But for this project I really need this to work in Zend_Amf.
AS3:
var path:String = "/images/picture.jpg";
var ba:ByteArray = jpgencoder.encode(bitmap.bitmapData);
var nc:NetConnection = new NetConnection();
nc.connect(zend_amf_server);
nc.call("Service.saveJPG", new Responder(responseHandler, errorHandler), path, ba);
PHP:
class Service{
public function saveJPG($path, $byteArray){
return "worked";
}
}
I was getting the same error from Zend AMF tonight doing basically the same thing with code that previously worked in AMF. Here's what I have that's working. The only bit I spot different from your code is I'm only passing the ByteArray to Zend, and I'm explicitly setting the ObjectEncoding.
I kept getting empty jpgs on the server because I'd read elsewhere that I needed to do ->data to get to the ByteArray data.
AS3:
_service = new NetConnection();
_service.objectEncoding = ObjectEncoding.AMF3;
_responder = new Responder(this._onSuccess, this._onError);
_service.connect(zend_amf_server);
var myEncoder:JPGEncoder = new JPGEncoder( qualityValue );
var myCapStream:ByteArray = myEncoder.encode ( myBitmapSource ); // myBitmapSource is BitmapData drawn from a Sprite
this._service.call("Remote.savePhotoToServer", this._responder, myCapStream);
PHP:
function savePhotoToServer ( $pInfos )
{
$bytearray = $pInfos;
$idimage = $this->nameImage(".jpg"); // calls a private func for a new name
return ( $success = file_put_contents("./_photos/".$idimage, $bytearray) ) ? $idimage : $success;
}
Thanks David for your reply, the problem seemed to be that I sent a ByteArray to Zend_Amf together with a String.
If I send the ByteArray only it works fine and the Image is saved.
The only problem now is that the path to save the image on should be variable and I can't send it over to my Amf_Server together with the ByteArray at the same time.
Ok, I found the problem. I was using the Zend Framework in the latest 'tag' repository v. 1.7.5 I switched the repository for AMF to the the 'trunk' repository and now it works. There was a bug in Zend_Amf_Server when sending Arrays over to it.

i am a beginner. I'm starting to learn Adobe Flash. I followed the code on Google on AS2:
l = new LoadVars();
l.onLoad = function(ok) {
ttl0=l.ttlslv0; atc0=l.atcslv0;
ttl1=l.ttlslv1; atc1=l.atcslv1;
};
l.sendAndLoad("http:localhost/getdata.php", l, "POST");
with php like this:
<?php
include_once("koneksi.php");
$qr = mysqli_query($con,"SELECT title, article from $tabel");
$nr = 0;
while($kolom=mysqli_fetch_row($qr) )
{
$ttl=$kolom[0];
$atc=$kolom[1];
echo "&ttlslv$nr=$ttl&atcslv$nr=$atc";
$nr++;
}
echo "&nr=$nr&";
?>
with the results that I can specify "what row" and "what column" will I take.
can this be changed to AS3 with the same results?
I have difficulty studying AS3
anyone want to give me a solution? thanx...
In AS3 you use the URLLoader class to load text/binary data. To work with URL-encoded strings you need the URLVariables class.
Something like that (not tested, no error handling either, just a common guideline):
// URLRequest instance holds various information
// about what, where and how you send.
var aRequest:URLRequest = new URLRequest;
// URL address.
aRequest.url = "http://localhost/getdata.php";
// Request method (POST or GET mostly).
aRequest.method = URLRequestMethod.POST;
// URLLoader instance performs the requested operations:
// uploads the request and relevant data, reads the answer,
// and dispatches all the events about any status changes.
var aLoader:URLLoader = new URLLoader;
// Tell the URLLoader that the answer is
// an URL-encoded text of key=value pairs.
aLoader.dataFormat = URLLoaderDataFormat.VARIABLES;
// This event handler function will be triggered
// upon successfully completed operation.
aLoader.addEventListener(Event.COMPLETE, onData);
// Start loading.
aLoader.load(aRequest);
// The COMPLETE event handler function.
function onData(e:Event):void
{
// Unsubscribe from the event. For the most part it is
// a GOOD idea NOT to re-use any network-related
// class instances once they've done their job.
// Just unsubscribe from all their events,
// dismantle their data structures, purge
// any references to them and let the
// Garbage Collector do his job.
aLoader.removeEventListener(Event.COMPLETE, onData);
// Retrieve the object that contains key=value pairs.
var anAnswer:URLVariables = aLoader.data as URLVariables;
// The data you wanted to get.
trace(anAnswer.ttlslv0);
trace(anAnswer.atcslv0);
trace(anAnswer.ttlslv1);
trace(anAnswer.atcslv1);
}
UPD: It seems that you are dealing with escaped text there. I composed a simple script that explains how it works:
import flash.net.URLVariables;
var V:URLVariables = new URLVariables;
var S:String = "a=1&b=2";
V.decode(S);
trace(V.a); // 1
trace(V.b); // 2
S = escape(S);
trace(S); // a%3D1%26b%3D2
trace(unescape(S)); // a=1&b=2
V.decode(S); // Error #2101
So, there are two options you can work on:
Figure out why server passes the escaped string and prevent it.
Load the server's answer as a plain text (URLLoaderDataFormat.TEXT instead of VARIABLES) so the URLLoader.data will be just a simple String, then unescape(...) it if necessary and feed to the URLVariables.decode(...).
I'm trying to update a template document via PHP API using this: https://github.com/docusign/docusign-php-client/blob/master/src/Api/TemplatesApi.php#L4946
I get one of two errors depending on if I set the apply_document_fields option.
Without it set, I get UNSPECIFIED ERROR Value cannot be null.\r\nParameter name: fileBytes. However, if I view the request body before sending, document_base_64 is set as expected.
With apply_document_fields set 'true' (actual boolean value is not supported), I get FORMAT_CONVERSION_ERROR The data could not be converted.
Either way, it seems like the document data is not getting sent correctly, but I can't figure out how I'm supposed to be sending it. Here's my code:
public static function updateTemplateWithDocument(string $documentId, string $templateId, $documentBody = null)
{
$api = My_Service_Docusign::getInstance();
$templatesApi = new DocuSign\eSign\Api\TemplatesApi($api->getAuth());
$document = new \DocuSign\eSign\Model\Document();
$document->setDocumentBase64(base64_encode($documentBody));
// Got an error reusing $documentId, so I'm incrementing it now
$document->setDocumentId((string) (((int)$documentId) + 1));
$def = new DocuSign\eSign\Model\EnvelopeDefinition();
$def->setDocuments(array($document));
$opts = new \DocuSign\eSign\Api\TemplatesApi\UpdateDocumentOptions();
// Different behavior with this set vs not
$opts->setApplyDocumentFields('true');
$res = $tmpApi->updateDocument($api->getAccountId(), $documentId, $templateId, $def, $opts);
return $res;
}
Unfortunately, DocuSign support doesn't support their API :-(
I figured out I need to use TemplatesApi::updateDocuments (plural) instead, which also allows me to reuse the documentId.
I am having a problem passing an array variable from Flash (AS2) to PHP. In action script I have several arrays defined like this
output["px1"]
output["px2"]
output["px3"]
and then I use the following code to pass the variables into a php file
output.sendAndLoad("orders/print2cart.php",output,"POST");
I want to know how to get the data from the array in PHP. I have tried using $_POST['px1'], $_POST['output']['px1'], $_POST['output'] but I cannot seem to get any data. Any ideas as to what I can change to get the desired result?
Thanks!
EDIT: Just noticed that I one of the other variables in output (output.username) is also not being sent to PHP, despite it showing up in flash. Using the following code to alert to flash and it does show all the variables correctly.
getURL("javascript:alert('Print Stamp: " + output.PrintStamp + " User: " + output.username "')");
EDIT: Seems like once I send a pretty long array (or a string for that matter) none of the other fields associated with the LoadVars variable are sent either. I googled it up for limits and it says text limits are ~ 63000. Still not sure if that is the problem
Try it as a String.
Use Array.join(); in flash and send the value returned by that, then use explode() in PHP convert it back to an array.
var dataOut:LoadVars = new LoadVars();
var dataIn:LoadVars = new LoadVars();
dataOut.info = your_array.join("#");
vars.sendAndLoad("url", dataIn, "post");
dataIn.onLoad = function(go:Boolean):Void
{
if(go)
{
trace('success');
}
else trace('connection failed');
}
The PHP:
<?php
$str = $_POST["info"];
$myarray = explode($str);
?>
Since there were no other alternatives and I went through a lot of stuff before finally concluding that Arrays of large sizes cannot be passed through from AS2 to PHP very easily. My array was actually an image converted to pixels, so what I did was that I split the array into 2 pieces and posted to the PHP file twice instead of only once. Another alternative would be to split and post the array to a text file first and then read that text file directly from PHP.
You can do the same as you would do with HTML, by naming your parameters "array[0]", "array[1]", etc... :
var urlVariable:URLVariables = new URLVariables();
urlVariable["phpArray[0]"] = "arrayEntry0";
urlVariable["phpArray[1]"] = "arrayEntry1";
var loader:URLLoader = new URLLoader();
var request:URLRequest = new URLRequest("http://yourserver.com/phpScript.php");
request.method = URLRequestMethod.POST;
request.data = urlVariable;
loader.load(request);
then serverside you can verify the result received by php script :
print_r($_POST);
it should output :
Array
(
[phpArray] => Array
(
[0] => arrayEntry0
[1] => arrayEntry1
)
)
and for multiple dimension array you can use :
urlVariable["phpArray[0][0]"]
I have a Flash developer I'm working with. This person is building a tool in AS2 that will provide an interface that will send voting data (firstname, lastname, email address, votes (there are 100 items in categories and users will be able to choose some subset to declare "best").
All fair enough, Flash dev will POST data to a PHP app I will develop, and I will store the data in MySQL. This Flash dev has not done a great deal of work with databases or web apps.
I want to return data back to the Flash application. I want to be able to return "email address invalid" or "problem connecting to database" or "vote information accepted" messages. My instinct is to want to send back JSON or XML data. But I'm wondering if there are tools in AS2 to easily consume such responses.
I would like to see some "Hello World" type examples of AS2 code that consumes JSON or XML data so I can get the Flash app and the PHP app interacting well. My understanding is AMF is not on the table because it's AS2, but I'm open to what will work on both ends given the constraint of it being AS2.
Below should give you an example.
XML:
<alldots>
<dotname id="bigDot" color="0xff0000" url="http://www.fletchermartin.com/" photos="8" />
<dotname id="otherDot" color="0x000066" url="http://www.ajc.com/" photos="8" />
<dotname id="thirdDot" color="0xCC0099" url="http://www.tiffanybbrown.com/" photos="0" />
</alldots>
AS2 Code
var dots:XML = new XML();
dots.load('bigdot.xml');
dots.onLoad = function(success:Boolean){
if(success){
if(dots.status == 0){
var dotsToXMLString:String = new String(); // initializes a new string variable
dotsToXMLString = dots.toString(); // converts dots XML object to a string and stores it in dotsToXMLString.
var dotsXML:XML = new XML(dotsToXMLString);// creates new XML object with the string contents from above.
dotsXML.parseXML(dotsToXMLString); // parses the string from above.
var dotsNodes:Object = dotsXML.firstChild; // Saves the firstChild (in this case, the outermost element) as an object
var dotsNodesChildren:Object = dotsNodes.childNodes; // Saves the childNodes of firstChild as an object
for(i=0;i<dotsNodesChildren.length;i++){
var newObj:Object = dotsNodes.childNodes[i].attributes.id; // creates a new object out of the child node's id.
var newObjColor:Color = new Color(newObj); // creates a new color object with newObj as its target
var theColor:Number = dotsNodes.childNodes[i].attributes.color; //retrieves the hex code value (number) of the attribute color
newObjColor.setRGB(theColor); // sets the RGB value of newObjColor.
}
} else {
trace("Problem parsing XML.");
}
} else{
trace("Could not load XML");
}
}
I'm writing an application that downloads an XML string from a URL and POSTs that to another URL (that's set up to handle an incoming "XML" field). I've got the first part right - it downloads the XML and I can alert() it and all that, but I'm unable to figure out how to POST that data to a server.
function pull() {
var myLoader = new air.URLLoader();
var myRequest = new air.URLRequest('http://something/something.xml');
myLoader.addEventListener(air.Event.COMPLETE, pulled);
myLoader.load(myRequest);
}
function pulled(evt) {
if (evt.target.bytesTotal>0) {
// alerting shows the full string just fine
alert(evt.target.data);
var myLoader = new air.URLLoader();
var myRequest = new air.URLRequest('http://someplace/push.php');
myRequest.method = air.URLRequestMethod.POST;
// myVars = new air.URLVariables("xml="+evt.target.data); //
// alert(evt.target.data.toUpperCase());
myRequest.data = "xml="+evt.target.data; // myVars;
myLoader.dataFormat = air.URLLoaderDataFormat.TEXT;
myLoader.addEventListener(air.Event.COMPLETE, pushed);
myLoader.load(myRequest);
}
}
I made the 2nd server PHP echo the contents of the xml variable, but I'm just unable to get the exact contents of the XML string. There is something I'm doing wring with the myRequest.data and/or dataFormat bit.
Can someone just figure this out? I know it's probably a simple thing, but I'm at my wit's end right now.
This is my first AIR app.
Another related question (or sub-question) is that...
alert(evt.target.data); // shows an alert box with the XML
alert(typeof evt.target.data); // shows String
alert(evt.target.data.toUpperCase()); // shows the xml converted to upper case
alert(encodeURI(evt.target.data)); // shows up blank.
alert(escape(evt.target.data)); // shows up blank.
Why??
The error seems to be the way you are assigning the parameters to 'data' ... Use URLVariables.
var params:URLVariables = new URLVariables();
params.[name of parameter] = [value];
--- so like params.xml = (YOUR XML) ... from your example:
// uses the dynamic object to add the 'xml' property to 'params' at runtime.
params.xml = evt.target.data
Then Change you request.data to request.data = params;
-- The URLVariables guy is dynamic - so you can add properties as I describe above.
For a basic example - much more complete that what I have here: http://livedocs.adobe.com/flex/3/html/help.html?content=data_access_2.html
