Flash - How To Make Synchronous URL Requests From AS

Sep 13, 2010

I have a big loop in actionscript that sends lots of data to an url:
for(var i=0;i<1000;i++) {
var request:URLRequest = new URLRequest();
request.url = url;
request.method = URLRequestMethod.POST;
request.data = data;
var loader:URLLoader = new URLLoader();
loader.load(request);
}

The problem is because URLLoader can make only asynchronous calls, it sends all those thousands requests at once which kills webserver. Also it acts a bit strange on top of that. Lets say the loop is running for 5 minutes. For whole 5 minutes there is no requests coming to web server, then at the end they all are sent at once. I already tried everything I could possibly think of (empty loops, callbacks, delays) - nothing works. All requests are sent at once no matter what. How to make requests synchronous, so it will send one request after another?

Flex :: Multiple HTTPService Requests With AIR

Nov 17, 2009

I am developing an AIR application with Flex Builder that requires me to make two HTTPService requests at the same time. They both use different instances of the HTTPService AS3 class. Both services are calling a RESTful API which is currently running on my localhost (XAMPP) and takes a few seconds to respond (much quicker on live server). The problem is that most of the time one of the calls fails, however occasionally they do both work. Its also random as to which call will fail. Both calls use code something like this. This code is basically repeated in two classes.

Flex :: RemoteObject Synchronous Call?

Oct 1, 2009

In the code below when I call chkAuthentication function from another function the remoteObj.login (login function in my service file (.php)) is called after the remaining code in that function. i.e., the loginStatus is returned from the function before the result-handler function loginResult is called. but my loginStatus is supposed to be set in loginResult function. It seems that the asynchronous behaviour is the culprit. what should I do in order to get the loginResult function to complete first?

Flex :: Synchronous Calls Using RemoteObject?

Is there a way to make synchronous calls using RemoteObject in Flex?

Solution: Add the second call to the result handler of the first call, having a token check for multiple originating calls.

Flex :: Programming Synchronous Web Service Calls

Aug 19, 2009

Web service calls are asynchronous in flex, but I wanted to wrap a web service call in a class to provide synchronous encapsulation. Something like the below - the user could call getMyMethodResult and get the result returned by the web service. I expected the thread that recieved the soap response would populate the variable _result and mean that getMyMethod would, after a time, find _result is not longer null. But it doesn't! Can anyone explain why this does not work?[code]

Flex :: Synchronous - Action Wait For Network Response?

Jun 22, 2011

I have small Flex web based util with single button. On this button click a request is sent to server and the response must be read in the same call.This is important not to wait for response with event handler (which is trivial).Basically this is synchronous call.I am ok with blocking ui and so on.

Flex :: Can Do Conditional GET Requests From Flash / AS?

Feb 19, 2010

I have a Flex client that loads data from a server to display a chart. This data may change, so the client regularly repeats the request. Since the result may require some work to retrieve, I'm going to have the server detect if the result has changed, and issue a 304 status if it hasn't.I haven't seen any headers in the Flash Player's requests which would indicate that it's already handling conditional GETs. Also, the HTTPService API doesn't seem to provide anything, either. Does that mean, Flash can't do this, or how can I implement this myself?

With regards to cookies, which aren't supported in Flash, I have heard the suggestion to build my own HTTP client on top of the Socket class. This might solve this issue, too, but frankly, I'm really not keen on doing that.As an alternative, I could just cache the result page and send it again, but so far, the API tries to utilize semantics that are already built into HTTP, and I'd like to keep it that way.

Flex :: Blazeds - RemoteObject - Handling Multiple Requests?

Jul 11, 2009

I have a couple of remote object methods that I want to respond to in different ways depending on the context, but I'd rather not set up a bunch of different RemoteObject aliases.Some background: Let's say I have an admin application that displays sales stats in different ways. The remote method looks like:

<mx:RemoteObject id="rpt" destination="AMFServer">
<mx:method name="getSalesStats" fault="getSalesStatsFault(event)"
result = "getSalesStatsSuccess(event)" />[code]........

The getSalesStats method takes an employee ID and a sales type as its arguments. You'd call it like:

rpt.getSalesStats(120, "peanuts");
public function getSalesStatsSuccess(e:ResultEvent):void {
salesdata:ArrayCollection = e.result.rows as ArrayCollection;[code]......

I'd like to pass something through the remote method to the responding function, like:

rpt.getSalesStats(120, "peanuts", "clicked button one");

but that of course throws an error because the server doesn't want that last argument.

Flex :: In Mate, Sending Two Or More Requests To The Server Simultaneously?

Sep 29, 2010

I'm using Mate's RemoteObjectInvoker to call methods in my FluorineFX based API. However, all requests seem to be sent to the server sequentiality. That is, if I dispatch a group of messages at the same time, the 2nd one isn't sent until the first returns. Is there anyway to change this behavior?

Flex :: Multiple Async Webservice Call Requests?

Jul 26, 2011

I am using Flex and Actionscript 3, along with Webservices, rpc and a callResponder. I want to be able to, for example, say:

loadData1(); // Loads webservice data 1
loadData2(); // Loads webservice data 2
loadData3(); // Loads webservice data 3

However, Actionscript 3 works with async events, so for every call you need to wait for the ResultEvent to trigger when it is done. So, I might want to do the next request every time an event is done. However, I am afraid that threading issues might arise, and some events might not happen at all. I don't think I'm doing a good job of explaining, so I will try to show some code:

private var service:Service1;
var cp:CallResponder = new CallResponder();
public function Webservice()[code]....

I could ofcourse save the actions in an arraylist, but whose to say that the addToArrayList and the check if other calls are available do not mess eachother up, or just miss each other, thereby halting execution? Is there something like a volatile Arraylist?

Flex :: Duplicate Sessions Caused Multiple Requests With Different JSESSIONIDs?

Jul 7, 2011

I think I inherited bad code, here's the deal: In my command, I create a local var for the remote object and then call a method on it. In the result, if there's no data, I start a timer. This timer broadcasts an event every 2 seconds that continually calls this command until data is returned. Then the timer is stopped.

What we're seeing is that the method returns data once, and then the next time it doesn't (dupe Flex sessions error). It basically alternates. If we click really fast, sometimes we'll get two to work in a row. At times, the Java dev is seeing these requests returned with different JSESSIONIDs. I believe this is causing the duplicate Flex sessions error. I'm using Cairngorm; here's the execute command.

public function execute(event:CairngormEvent):void
{
ruleName = (event as FetchReportEvent).ruleName;
var ro:RemoteObject = ServiceLocator.getInstance().getRemoteObject("quantRemoteObject");
if (model.guid != null)

Actionscript 3 :: Capture And Alter All Outgoing Requests From A Flex Application?

Currently in my flex application, I've got all of the app's assets being served from my local server, but I want to be able to serve all of the assets from a CDN (URL...)

Python :: Flash - Handle Faults/exception In Flex In Http Requests?

Mar 15, 2012

Here is an issue i'm struggling to solve for quit some time now.I have a python + GAE backend with a flex client that communicates via JSON. I'm using flex's HttpService bound to a Responder with result and fault callbacks. When python raises an exception, I don't seem to get it in flex. I did some research and found out that the problem probably lies in the fact that the flash runtime cannot handle http responses with status code other than 200.

Flex :: Gzip - Flex - HTTPService And Gzipped Responses?

Jul 5, 2010

I have a Flex client making RESTful calls to a webservice using HTTPService. The server is returning JSON responses, which we would like to compress. Can Flex using HTTPService handle gzip-encoded responses? If so, what steps are required to make it work (e.g., which headers to set, how to decompress, etc.)? If not, can you suggest a simple alternative?

Flex :: Re-using HTTPService Object

Oct 22, 2009

I'm trying to reuse the HTTPService object in a flex app but I'm running into a problem. In the handler for ResultEvent.RESULT I'm removing the listener, but it isn't removed. I've have to catch the asyncToken from send() and attach a new property so I know what it's supposed to do in the handler.URL...You can right-click and view source.Has anyone else run into an issue where listeners aren't removed? Should HTTPService not be reused?

Flex :: XML HTTPService Result And For Each

Mar 3, 2010

XML is cool in flex, but I have an annoying problem to solve, caused by what I can imagine is a feature. You see, when you have just one tag of something, it creates an object which is not an array. But when finds more than one, it puts it on an array structure.[code]I could check the format of resObj.specifictag (to check if it is has an array) and then duplicate the code (for each case). But -even if it's calling a function- I don't think it is an elegant solution.Well, I hope someone has a good idea on this matter. (I know from experience that SO has much more C++ experts than flex, but well...)The perfect thing would be that HTTPrequest handled every tag in a consistent way (using always arrays... though I'm guessing that that would also have its drawbacks).

Flex :: Flex3 - ConcurrencyError Using HTTPService

Aug 21, 2009

I'm getting occasional ConcurrencyError faults when using HTTPService in Flex 3. I have four HTTPService objects, all configured with concurrency=single. I'm not sure though how to continue to diagnose, as I don't see in the FaultEvent what service object caused the issue, and I can't easily reproduce it on-demand.

One feature of my app is that I am also using a URLRequest to load a sound shortly after receiving a result from one of the HTTPService calls. Could this be related to the concurrency error?

The fault looks like this:

[FaultEvent fault=[RPC Fault faultString="Attempt to invoke while another call is pending. Either change concurrency options or avoid multiple calls." faultCode="ConcurrencyError" faultDetail="null"] messageId=null type="fault" bubbles=false cancelable=true eventPhase=2]
