I'm developing a Flex mobile application and I'm using the Http Services within FlashBuilder (4.7) to send/receive data. I'm having some issues with how the server is setup to accept calls (from the mobile platform) and apparently setting the User-Agent in Android works just fine. But I can't seem to be able to find a way to set the User-Agent in FlashBuilder.
Any ideas?
Thanks
var request:URLRequest=new URLRequest('URL_OF_YOUR_SERVICE');
var userCredential:Object = new Object();
userCredential['user_email'] = 'YOUR_MAIL';
userCredential['user_password'] = 'YOUR_PASSWORD';
request.data=JSON.stringify(userCredential);// use this if your service accept json only else give Object directly
request.method = 'post';// specify here method GET or POST
var loader:URLLoader=new URLLoader();
loader.addEventListener(Event.COMPLETE, userLoginCompleteHandler);
loader.addEventListener(IOErrorEvent.IO_ERROR, onIOErrorHanlder);
try
{
loader.load(request);
}
catch(error:Error)
{
trace("Login Error:: "+ error.toString());
}
may this will help you, here i have defined userLoginCompleteHandler and onIOErrorHanlder event listner for result and fault.
No, you can't set the User-Agent header in Flex.
From this Adobe forums post:
Note again that since the underlying Flash API is flash.net.URLLoader there are certain headers that
you cannot send. For details, please see the docs for flash.net.URLRequestHeader.
The URLRequestHeader docs say:
In Flash Player and in Adobe AIR content outside of the application
security sandbox, the following request headers cannot be used:
... User-Agent, ...

Since Flash plugin has reached EOL, the only way to still use my RIA is to use the standalone version of Flash player.
I've noticed an issue with the following piece of code while testing the migration:
var request:URLRequest = new URLRequest("/utils/function");
request.contentType = "application/x-www-form-urlencoded";
request.method = URLRequestMethod.POST;
var data:URLVariables = new URLVariables();
data.x = encodeURIComponent(1);
data.y = encodeURIComponent(2);
data.z = encodeURIComponent('some value');
request.data = data;
navigateToURL(request, "_blank");
The standalone version of flash (v30.0.0.134) makes a GET request instead of the instructed POST method. The browser plugin (v32.0.0.238) opens the page correctly in a new tab as a POST request.
Why does the standalone flash convert my request in to a GET? Anybody out there who can shed some light on this issue?
I don't know if it qualifies as a answer, but we use this to make a POST request:
handleService.url='.../something.ashx';
handleService.method = URLRequestMethod.POST;
var prm:Object=new Object();
prm.par1 = "asd";
prm.content=encodedData;
prm.fileName=FileName;
handleService.send(prm);
Instead of going for a standalone version of flash, you can package the app as a Adobe AIR runtime. We still use some apps written in Flex and have no issues with them.
If running on windows, you can package it as a native runtime and works nice.
Alright I have my sqldb hosted online and can access it using phpmyadmin what i would like to do is create tables and add items to the tables via adobe flex builder 4.6 desktop AIR application.
Anyone know if i am able to do this, the idea for the program is so person at position A can enter a name and person at position B can then use his program to read those names
According to Accessing mysql from Adobe flex/AIR, AIR is unable to access MySQL servers directly, so you'll have to use web services or some custom API do to this. But yeah, sure it's possible to do what you want.
I agree with Isaac. However, I want to add that it is good coding practices to not allow client side applications modify a database directly. In the applications that I have built, I like to use PHP to set-up an API that then interacts with the database. The AIR application then the interaction with the API using HTTP Requests.
Following code shows how to perform a URL request from the Adobe Website.
http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/net/URLRequest.html
var url:String = url location of the API;
var request:URLRequest = new URLRequest(url);
var variables:URLVariables = new URLVariables(); //create variables to pass to the API
variables.exampleSessionId = new Date().getTime(); //create variables to pass to the API
variables.exampleUserLabel = "guest"; //create variables to pass to the API
request.data = variables; //Add the variables to the request
request.method = URLRequestMethod.POST; //Set the method of the Request GET, POST, PUT
navigateToURL(request); //Executes the request
You'd probably like something like https://backendless.com/ for this.
I'm attempting to send a POST request with data to another domain with this code:
_snapshot_id = 1369022400;
var urlRequest:URLRequest = new URLRequest("https://fuzzykittens/radar");
urlRequest.method = URLRequestMethod.POST;
urlRequest.contentType = "application/x-www-form-urlencoded";
//set variables for post
var postVars:URLVariables = new URLVariables();
postVars.snapshot = String(_snapshot_id);
urlRequest.data = postVars;
//initialize weather proccess request
weatherProcRequest = new URLLoader(urlRequest);
weatherProcRequest.addEventListener(Event.COMPLETE,
weatherProcRequest_CompleteHandler);
weatherProcRequest.addEventListener(IOErrorEvent.IO_ERROR,
weatherProcRequest_ErrorHandler);
weatherProcRequest.addEventListener(SecurityErrorEvent.SECURITY_ERROR,
weatherProcRequest_ErrorHandler);
weatherProcRequest.load(urlRequest);
When I set the flex compiler to use an HTML wrapper, the request works. When I don't use a wrapper, the request throws an io error #2032. I think it's not sending the snapshot id, but I don't know why.
Is there any obvious reason why a request would send data when debugged in an html wrapper and fail to do so when debugged outside an html wrapper?
fuzzykittens has a crossdomain.xml with
<allow-access-from domain="*" secure="false"/>
I found the issue. Adobe very briefly mentions this caveat in URLRequest's livedoc:
Note: If running in Flash Player and the referenced form has no body, Flash Player automatically uses a GET operation, even if the method is set to URLRequestMethod.POST. For this reason, it is recommended to always include a "dummy" body to ensure that the correct method is used.
When I just ran the SWF without a body, the snapshot id was not sent as a post var so the server responded differently.
It's definitely not the answer I wanted, but it feels good to know what was going on. Thank you for your comments.
I have a small multiplayer Flash game in which you can display a player profile by clicking at his or her avatar:
const PROFILE_URL:String = 'http://myserver/user.php?id=';
try {
navigateToURL(new URLRequest(PROFILE_URL+id), '_blank');
} catch(e:Error) {
}
This works well, but now I'd like to extend the user.php, so that players can add comments about each other. For authorization I'd like to use HTTP cookies, passed from the game.swf to the user.php.
(I don't want use GET or POST here, because GET will have the auth. variables in the URL and players might occasionaly send that URL around or post it in my forum. And POST will ask to re-post the request when you reload).
My problem is that I can't find the way to set HTTP cookies through the navigateToURL() method. Please advise me
Regards,
Alex
You could first authenticate by logging in via a seperate call, for example login.php and that script would start a session. Then all other calls to the same domain would already have the session started and you could check authentication. No need to worry about cookies when PHP can do it for you.
Assuming that you already have the cookie value in your swf you should be able to use the URLRequestHeader together with the URLRequest as follows:
var header:URLRequestHeader = new URLRequestHeader("Cookie", "<the cookie>");
var request:URLRequest = new URLRequest("http://example.com/script.php");
request.requestHeader.push(header);
request.method = URLRequestMethod.POST;
navigateToURL(request, "_blank");
Under certain circumstances, the browser will send the cookie to the server if it has been already set even if you don't explicitly include it in the request. This depends on the browser and the version of the Flash Player. You might also need to adjust your crossdomain.xml file.
Also note that there might be security implications of passing around an unencrypted cookie token. See Firesheep.
I'm using URLLoader to POST to a server. The xml response from the server can respond with a 404 or a 403 (forbidden) error. However I am unable to get the response codes.
Here is the code
var urlString:String = "some url";
var urlRequest:URLRequest = new URLRequest(urlString);
var loader:URLLoader = new URLLoader();
loader.addEventListener( Event.COMPLETE, setXMLData );
loader.addEventListener( IOErrorEvent.IO_ERROR, ioHandler );
loader.addEventListener( HTTPStatusEvent.HTTP_STATUS, httpStatusHandler );
//...
public function httpStatusHandler(evt:HTTPStatusEvent):void {
trace("status is " + evt.status);
}
status is always 0 regardless whether i return 200, 400, 404, 301, 500, etc...
Any ideas?
For AIR Only you can use the httpResponseStatus. Otherwise in Flash/Flex without AIR you cannot.
http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/flash/net/URLLoader.html#event:httpResponseStatus
httpResponseStatus Event
Event Object Type: flash.events.HTTPStatusEvent
HTTPStatusEvent.type property = flash.events.HTTPStatusEvent.HTTP_RESPONSE_STATUS
Language Version : ActionScript 3.0
Runtime Versions : AIR 1.0 AIR 1.0
Dispatched if a call to the load() method attempts to access data over HTTP, and Adobe AIR is able to detect and return the status code for the request.
Unlike the httpStatus event, the httpResponseStatus event is delivered before any response data. Also, the httpResponseStatus event includes values for the responseHeaders and responseURL properties (which are undefined for an httpStatus event. Note that the httpResponseStatus event (if any) will be sent before (and in addition to) any complete or error event.
the ability to look at the headers is limited in several browsers, therefore flash has a problem with being passed the information. this is mainly blamed on the browser settings, but i have yet to find one where it actually works. status event output.
i gave up and had the file print the response code in my projects, not wonderful (and somewhat defeating the point) but seems to work.
As a late answer (FWIW):
From what I've read, the status codes you get depend on what browser the Flash player is running in.
One article says you can only get 200 or 500. One SO question says they were getting 207 in Chrome but 0 in Firefox.
I, personally, have tested using the dev Flash player as well as an ActiveX version and was able to get many different 2XX/4XX HTTP status codes (but couldn't get the 3XX redirect codes I tried because the requests got redirected and returned 200s).
