ActionScript 3.0 :: Json - Use A JSON API In Flash?
Jan 15, 2012
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]
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?
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?
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?
I know most people hate 100% flash-based websites, but I was recently forced to use flash for a college assignment. After creating a fully-featured ria in less than 2 weeks with every feature I could imagine, i've regrettably fallen in love with this beast (which I previously refused to touch with a stick) due to the power of AS3 and the ability to sprinkle it everywhere :-
I now want to port a commercial desktop application of mine (which has been largely unsuccesful) to the web and feel flash/flex is an excellent candidate. While creating a html/css/js version would be ideal (working browser shortcuts, for a start), i'm certain it'll take a year to create in cross-browser html/css/js what would take just ~3 months in flash. Obviously as the (paid) desktop product was unsuccessful, i'd want to minimize the risk/investment in the (free) web application.
I plan on using JSON for web services, so it shouldn't be a huge pita to port in the future.Is this a good strategy for launching a web app you're not yet 100% committed to? Or will the fact i'm using flash doom me from the start? Has anybody else done this? If so, how did your userbase respond to the 100% usage of flash, and did you get around to porting it to standard web technologies?
I have read a lot about parsing JSON with Actionscript. Originally it was said to use this library. [URL] but it seems Flash Player 11 has native support for it now. My problem is that I cannot find examples or help that takes you from beginning to end of the process. Everything I have read seems to start in the middle. I have no real experience with JSON so this is a problem. I don't even know how to point ActionScript to the JSON file it needs to read.
I have a project with a tight deadline that requires me to read twitter through JSON. I need to get the three most recent tweets, along with the user who posted it, their twitter name and the time those tweets were posted.
The back end to this is already set up I believe by the development team here, therefor my JSON files or XML just needs to be pointed to and then I need to display the values in the interface text boxes I have already designed and created.
note: using django/python/javascript/flash So its been two days since I'm stuck at the error. I did the things you told me to and found a couple of ways around it but nothing worked. These are the results.Javascript does not receive the normal string it has to be a json object so. in views.py
somestring = json.dumps("HELLO WORLD")
which renders this in HTML
"HELLO WORLD"
and in javascript it is rendered like this
a240527176321_quote_hello
Now, since it is a json object I need to convert it back in flash. But when it gets in flash where I receive it like this
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...)
We have a game built in Actionscript 3, but for some users when they load the game it's loading the cached version of their saved game (JSON string) instead of getting the latest one from the server. We've implemented a random string at the end of the request URL, and I've also added headers for pragma and cache-control to the request. I'm not sure if adding those headers will make a difference though.
var jsonResponse:Object = JSON.decode(response); var foo:Object = JSON.decode(jsonResponse.nested); var bar:Array = foo as Array;
When i inspect foo - its an object with about 50 children objects.I can read the properties of the children objects. However, when i cast foo as an Array it comes back null.I'd prefer to not iterate over each object and push it into an array.
I know how to get json data into flash with twitter's search api because the array names normally aren't weird, but I'm not really too experienced with json. For the trends api data, I'm not sure how to access it because the array name is the date and theres spaces and colons in it, and I'm not really sure what to do. Normally in flash to get the json data I'd do something like
json.trends[0].2012-01-21 01:20.name
but that doesn't work. Can someone tell me how to pull out the name data when the array name is the date. I apologize if I'm calling these things the wrong name, I'm not too sure on what their proper names are. [URL]
i am having one form accepting json post in Asp.net which i need to call from Flash As3...
i am using below code to do that. I have seen some post in which they say its working fine. But i am encountering below Error
Error: Error #2101: The String passed to URLVariables.decode() must be a URL-encoded query string containing name/value pairs.
Here is my code.
var messages:Array = new Array (); messages.push({"From":fromemailTxt.text,"To": ToemailTxt.text,"Body": BodyText.text,"Subject":SubjectText.text}); var JsonObj:String = JSON.encode(messages);
Is it possible to call a web service from within Flash (using AS3)? Or is the best idea to put the flash movieclip in a Flex container and use the Flex Libraries?
To be clear, when I say within Flash, I mean within the Flash CS4, AS3 programming environment.
I'm having a problem parsing a JSON file in AS3. Im trying to parse multiple JSON arrays, but don't really know how to get to the next after accessing the first one. My JSON file looks like:
{ "term": [ { "id": 4211, "place": "NEW YORK CITY" }, {"id": 2675, "place": "WASHINGTON (DC)" [Code] .....
I can get the data from the first array, but how would I structure my code so that I could iterate through 2 or more "term" arrays?
so I have a JSON link that contains a couple of nodes (not sure what you call them in JSON) that I need to put into arrays in ActionScript, but I'm still having trouble trying to trace out all the specific node content.I found a similar question here, but the fix just showed how to trace out the entire JSON file (which shows up in my output window as [object Object],[object Object],[object Object],...)first node: {"captions":[{"content":"[hello world] ","startTime":0,"duration":4000}
My code:
private function onCaptionsComplete( event:Event ):void { //var jsonObj:Object = JSON.decode(event.target.data);[code].....
captions: undefined
TypeError: Error #1010: A term is undefined and has no properties.What I would like to be able to do is put the content data into the captionsContent Array, and the startingTime into a startingTime Array, same with the duration data.
I have a flash file which loads data from JSON and parses it. It works fine expect on one machine (specs below). On that machine it loads an image URL specified in the JSON, but nothing else. I've tested with a other machines (Dell E6400, Apple MacBook Pro) and it works just fine in all browsers. I compared Windows Updates between the Dell E6400 and the Dell Optiplex 745 and they only differ by one update (KB2525694) which isn't applicable for my Dell E6400.
