AS2 :: Json - Add A Request Header To A LoadVars When Using GET (Flash)?
Oct 29, 2010
I'm working on a project built in Flash AS2.One of the things I need to do is load JSON data. In the past, I've had no problem with this - LoadVars works just fine.However, on this project, the JSON service that I'm calling requires the http request to include an ACCEPT header with "application/json".
LoadVars has an addRequestHeader method that allows me to add or change HTTP request headers, but according to the documentation, those headers are only sent with POST actions.Of course, in my case, the JSON service only allows GET requests.I tried using addRequestHeader anyway, but the header is not sent.(Of course, I could rebuild the application using AS3, which allows me to use URLLoader and URLRequest, but the application has WAY to much legacy AS2 code...)
Is it possible to "POST" JSON data in the body of a request with LoadVars? I understand LoadVars sends data as name>value pairs. How can I send the data in the body instead?
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'm trying to reproduce a POST request that was captured from WireShark using PHP. This POST request was sent by a Flash (.swf) object, so it's a little bit complicated in configuring the header.It does not print out anything in the end, so there must be something wrong with PHP code that I could not see.Here is what WireShark captured:
POST /engine/ HTTP/1.1
Host: abcdef.com
User-Agent: Mozilla/5.0 (X11; Linux i686; rv:2.0) Gecko/20100101 Firefox/4.0
I have a script, either through Greasemonkey or as a Chrome extension, on a page that contains a Flash application. That flash application sends out POST requests e.g. [URL].
Is it possible for the script running on that same page to capture the request header sent by the Flash code? Kind of like Tamper Data, Fiddler and the like do. EDIT: Just a little more info. I don't need to redirect or alter the request coming from the Flash application. I just to be able to read in the header and save that information in a variable in the user script / extension that is running on the same page.
I am trying to make a simple POST using LoadVars. Since I am using an API there are some limitations though. The request must be send via POST with a JSON header. The body of the request should not contain name value pairs, but rather just a JSON object.
This last requirement has been troublesome for me because it seems like the only way to make a POST with LoadVars requires you to specify a variable name.
I am building a request in Flash that contains a JSON encoded Array of Objects. This is encoded using as3corelib. The request is then passed to JavaScript via ExternalInterface and a jquery ajax call sends the request off to the server.In PHP, the incoming data is parsed, but the json_decode returns null, giving a Malformed JSON error. var_dump results in comments:
<?php (isset($_POST['gdata']) && !empty($_POST['gdata'])) ? $gamedata = $_POST['gdata'] : returnError("game data not specified"); var_dump($gamedata);[code]............
What I don't understand is that attempting to decode the variable returns null, but the same text decoded from a literal string works fine. What can I do to clean up the incoming data and make it readable for json_decode?
Edit: php_info() says that magic_quotes_gpc is enabled. Could that be the issue?
With the Actionscript code below I'm sending an array to the server and receiving two responses: the HttpStatus response and a header with several information, like server info, location, etc. Does anyone have an idea how to read these server information? I cannot find any method or class, which would read the header info.
I'm trying to insert a HTTP header into the request that is made when a .SWF requests a .FLV movie via the flvplayback object. Here's my scenario.
We are using Akamai to distribute our flash video so it loads faster. Our current set up involvels 4 primary components:
1. HTML sitting on our corporate webservers. 2. SWF being served by the Akamai servers. 3. FLV file being served by the Akamai servers. 4. flvplayback skin (SWF file) being hosted by the Akamai servers.
When the HTML file loads into the browser, it requests the SWF, which then loads the flvplayback skin and FLV video. This whole process works until you add security to the mix. We have referer security, which means that that Akamai-hosted files won't load unless the requesting domain is one of our corporate domains. The referer is usually passed over in the HTML header, so the HTML file can successfully request and load the SWF from the Akamai servers. However, when the SWF then requests the skin and FLV file, they don't load because the referer header isn't passed over in this request.
How do I insert the referer header into the SWF request for the FLV and flvplayback skin? I'm assuming this needs to be done from within the flvplayback instance in my SWF file, but I don't know how to reference that. I tried the following, but it didn't seem to work:
I am using ActionScript 2.0 for my app development. I have checked XML and LoadVars class. These classes by default send/receive data either in XML or name/value pair format. I want to send data in JSON format and receive the response in JSON format. How can I achieve this behavior using AS2.0. I have noticed that AS3.0 has the capabilities to do so. My client platform doesn't support AS3.0.
The JAX-RS service receives the request and respond successfully with some dummy response, but I have no access to the request.data field.
How do I access the data of the request message (which is {"type":"get_configuration","data":"some data"} in this particular example)? I think that I'm supposed to add some parameters to the handleMessage method like
public SomeResponse handleMessage(Object message) {...
but this does not work at all. The request got 415 response.
I am trying to access html files protected by basic authentication. Below is the code to do that but I still get the authentication dialog. I checked the fiddler and found that for the first request authorization header is present but for the subsequent requests which is requested to load the .js, css & images the authorization header is not added. This is the reason I am getting the auth dialog. Is there a way to add authorization header to the subsequent requests as well?
I 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]
Created 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); public function getGridData():String {[code].....
However, when I sort a column in the user interface, the encode method is failing throwing the following error
Property usingCustomCompareFunction not found on mx.collections.SortField and there is no default value.
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 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?
When Flex application make an asynchronus HTTP request, does it add a special header to the request, like some JavaScript framework does? Something that indicates whether this request is an AJAX call/not.I just want my server side code to return different response format, depending on whether the request is made from browser/flex.
One of the moderators, could you've a look at this tutorial: [URL] it doesn't works with me, maybe because I've 2004 so if you change loadVars() into LoadVars() it should work
I'm trying to send array of data from Flash to PHP to sending e-mail. I'd like to do that because I must change the php page everytime my form site changes because of client's choice.[cod]e...
I'm trying to pull data into flash using JSON but i keep getting this error
JSONParseError: Unexpected < encountered at com.adobe.serialization.json::JSONTokenizer/parseError() at com.adobe.serialization.json::JSONTokenizer/getNextToken()
What 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.
What is the best way to pass JSON to and from a Flash movie?Currently to communicate between javascript and Flash :I'm using 'flashvars' to pass data to the flash movie when it initially loads I'm using 'ExternalInterface' at runtime to transfer single values, such as booleans at runtime I want to move to the next level and do this with JSON now.
Initially I just want the ability to send JSON to the flash movie on instantiation, but later i will need to send data back and forth.I just want to do it right first time and avoid any compatibility or 'gotcha' issues if there are any. i dont even know if i can pass a whole object to Flash, or if i need to serialize it as a raw JSON string.
I've flash app and i've static data (like ~18.0KB) for it which aren't changed often so I was wondering how to better get them. The static data may be in XML or JSON. One of my ideas was to put the static data in .js file within a function which would return them in JSON list and the other one was to return them in XML (as I like to work with XML more in Flash) somehow. But I'm not sure if it possible to put XML stuff in JS file to return them when function is called.. Or is XML pages also cached in browser and I will get the same performance result which I would get with cached JS files?
