Php :: What Is Deserialize & Serialize In JSON
Jul 23, 2010I'm new in JSON, but now I need to use JSON for my Flash ActionScript 3.0. So I found one lib for JSON and I have seen the terms Deserialize & Serialize what does that means.

View 1 RepliesAt the moment it seems I've tried every trick in the book trying to get this to work. I need some way of encoding AMF requests and then decoding the responses. At this point I don't care what language it's in, as long as it's doable and free (as in to me), however I would prefer PHP.I don't know what other information is needed
View 2 RepliesCreated an editable flex grid which exposes a method called getGridData() to javascript. I am using the JSON.encode() method of the [url]....library to convert the grid object's dataProvider into JSON before returning it.
ExternalInterface.addCallback("getGridData", getGridData);

However, when I sort a column in the user interface, the encode method is failing throwing the following error

I'm working on a Flash AS2 application that needs to post JSON data to a web service.In previous projects, I've used LoadVars.send() or LoadVars.sendAndLoad() successfully to manage this:
var send_lv:LoadVars = new LoadVars();
send_lv.data = JSON.stringify({some json object});
var response_lv:LoadVars = new LoadVars();
response_lv.onData = function(rawdata) {
[code]....
In somepage.php, I can grab that JSON data using $_POST['data'].However, on this project, the developer of the web service requires the JSON content to be the BODY of the request (i.e., not a name/value pair). Is this possible with LoadVars?

I have a pure ActionScript 3 problem, but the simplified test case I've prepared is in Flex 4 for better visibility (the source code is below): Since Flash Player 11 / AIR 3 support JSON natively, I've decided to move a multiplayer game, which used XML for communicating with server, to JSON. But I have a frustrating problem, that given two Objects like

I am sending a request to a server, and in return I get a long block of JSON.

Is there a way to do this? I checked if the property was enumerated and it returned true, but I cant find a way to access this data.
I have to work with webservices in Actionscript. I found the following code that allows me to use JSON URLs that implement only the GET method. However, it doesn't work for POST methods (doesn't even enter the "onComplete" method). How can i "POST" JSON data using Actionscript 3.0?

View 2 RepliesI was wondering if someone could explain or point me in the direction of how to implement an API that uses JSON in ActionScript 3.0. What I specifically want to know is how would I grab specific information. The following is how I do it in XML but I don't know how I would do something similar in JSON as in getting the equivalent of an XML tag. For example with the twitter API I'd like to grab the text [URL]

I have a class DataFile which is the top level class that I am serializing. DataFile contains an ArrayCollection which in-turn contains objects which extend ArrayData, each which overrides readExternal in different ways.
Over the course of the development the ArrayData object from version 1.0 is now different than the ArrayData object in version 1.1.
This causes deserialization to fail, most often with a null object error.[code]...

I want to serialize an object to AMF, and I want the result to be exactly the same as if it is serialized by NetConnection.call(). So, I use ByteArray.writeObject(), and the output bytes are usually the same as bytes sent by NetConnection.call(), but sometimes couple of bytes are different.
I found this in AMF3 spec: "Note that ByteArray.writeObject uses one version of AMF to encode the entire object. Unlike NetConnection, ByteArray does not start out in AMF 0 and switch to AMF 3 (with the objectEncoding property set to AMF 3)." It explains that differences.
We are developing an app with a Flex frontend and a C# backend, connected through web services. We are using the FLex Builder 3's Web Service Manager to autogenerate the webservice classes. The problem araise when Flex serialize our objects, for example, when we have a Number property with no value, this is serialized as NaN, and our backend doesn't know about NaN. Another example is when we serialize a cyclic reference, we get a stack over flow exception. I know in java, for example, you can configure the way xstream work with cyclic reference... So, the question is, can we change the way Flex serialize the objects so C# can work with this frontend? Is there any issue we should know about how flex serialize objects?

View 3 RepliesI am working on an inDesign Extension in flex where I am encoding an object to JSON and then later trying to create an object from the JSON String.

Currently, I do serialize my model object to the SharedObject instance:
try {
var mySo:SharedObject = SharedObject.getLocal("sig");
mySo.clear();[code]....
Likewise, I load the saved model using the SharedObject instance. Works great.Ultimately, I'd like to serialize it to a file - which fails. Here is how:
var fp: File = File.applicationStorageDirectory;
fp = fp.resolvePath( PREFS_FILENAME );
var _prefsStream:FileStream;[code]....
The complementing read operation suddenly breaks and reports missing bytes.In fact, I can't image how FileStream / _model.writeExternal() is able to serialize, since it needs to somehow know, that a new serialization operation is about to start. If it doesn't know, it won't be able to determine, which object instances are left to serialize.Thus, I image that my concept is completely wrong or I missed how to initialize the serialization operation.I'd be happy to read the raw ByteArray from the shared object and write it to a file. Unfortunately, I didn't find a method to retrieve from a SharedObject a ByteArray of a certain property, in my case mySo.data.model.My question is loosely related to this one: Why does delete( DictionaryInstance[ key ] ); fail?
I'm about to implement
public function writeExternal( output:IDataOutput ):void {...}
public function readExternal( input:IDataInput ):void {...}
to make a set of object serializable.
Although I'm pretty sure, that I implemented all correctly, readExternal(..) at a certain point complains about too few data left to read:
RangeError: Error #2006: The supplied index is out of bounds.

I wonder, if I have a circular object network like
A = { left -> B, right -> B }
B = { father -> A }
And I call
writeObject( a )
Will Flex serialize the hole object network and each object once and only one?
I did this:
Declared type annotations like this: [RemoteClass(alias="model.MyClass")]
Implemented parameter-free constructors
Declared all classes using implements IExternalizable
SharedObject's send() method is guaranteed to send each object once and only once.
Additional infos:
Reading and writing a ByteArray
Using Remote Object Components

There are options to do it using Java and JS. And these options can be clubbed with AS3 but is there something out-of-the-box in native AS3 to do it.
View 3 RepliesWhat I want to do is make a get request to this URL: [url]... which should return some JSON and then parse out certain information from it.
How would I go about doing this in Actionscript 3? I'm more concerned with figuring out how to get the data to feed to a JSON parser rather than parsing the JSON, since there seem to be plenty of questions about parsing JSON. The reason I want to do this in AS3 is that I have a 3D flash visualization set up and I want to get this data, parse out the relevant bits, and then display the parsed bits in the visualization.
