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'm getting a data feed from a client's supplier.
Documention says that I can get the feed both in XML and in JSON, but that the default is XML. To get JSON I have to set a header Accept:application/json and remove Accept:application/xml header.
I have not set nor removed any headers in my code.
I'm using a normal URLLoader to load the feed.
When I navigate to the feed url in a browser, I get XML.
When I run my code in FlashDevelop, I get XML.
When I run the exact same code in Flash Pro, I get JSON.
Does anyone have any idea what is causing this in Flash Pro? Any hidden setting that can be changed?
URLRequest.method has no impact. Debug mode or not has no impact.
I'm stomped.
---------code I tried------------
var header:URLRequestHeader = new URLRequestHeader("Accept", "application/xml");
var headers:Array = [];
headers.push(header);
urlReq.requestHeaders = headers;
urlReq.method = URLRequestMethod.POST;
--------- full load code -----------
_urlLoader.addEventListener(Event.COMPLETE, validateFeedLoaded);
_urlLoader.addEventListener(IOErrorEvent.IO_ERROR, handleFeedIOerror);
_urlLoader.addEventListener(SecurityErrorEvent.SECURITY_ERROR, handleFeedSecError);
var urlReq:URLRequest = new URLRequest(_feedUrl);
urlReq.requestHeaders = [new URLRequestHeader("Accept", "application/json")];
_urlLoader.load(urlReq);
Different clients/applications have different defaults. Different versions of the flash/air runtime may have different defaults for the accept type.
If you need consistency, then you should explicitly set the accept type in your request:
urlrequest.requestHeaders = [new URLRequestHeader("Accept", "application/json")];
This should ensure you get JSON back in both IDE's in whatever version of the runtime you're using.
i'm setting up a local SWF file that has to display some JSON data retrieved from a remote web server in some dynamic text fields.
Code:
Security.allowDomain("api.yourserver.com");
var loader:URLLoader = new URLLoader();
var request:URLRequest = new URLRequest("http://api.yourserver.com/yourendpoint");
request.method = URLRequestMethod.GET;
request.contentType = "application/json";
loader.load(request);
loader.addEventListener(Event.COMPLETE, decodeJSON);
function decodeJSON(event:Event):void{
var loader:URLLoader = URLLoader(event.target);
var Info:Object = JSON.parse(loader.data);
cont.textfield1.text = Info.text.field1;
cont.textfield2.text = Info.text.field2;
cont.textfield3.text = Info.text.field3;
}
Control > Test - It works. When run standalone it doesn't. I get the 2028 error (sandbox violation).
What i tried:
The LoaderContext method explained here on StackOverflow but i get a 2124 error (Loaded file is an unknown type - seems like the Loader method can only be used with stuff like SWF or medias like JPG etc.);
Setting local playback as described always here on StackOverflow but it didn't help;
Setting up and exception in the Global Flash Player Trust directory as explained here but got the 2028 again;
Anyone who was able to overcome this and willing to explain how or at least pointing in the right direction?
Thanks in advance!
I think that your current published file has just assess to local files only and not network ones, that's why you got security #2028 error.
To avoid that, you can change the Local playback security for your published swf from the Publish Settings to Access network only :
If you still get security errors when testing locally ( like #2048 error ), take a look on my answer of this question to add your local swf file to the trusted locations ...
Hope that can help.
I'm trying to get the head of a page without downloading the whole thing, because it's too heavy and I just need the header information.
The code is this:
var resource:String = "<myResource>";
var urlRequest : URLRequest = new URLRequest(resource);
urlRequest.method = URLRequestMethod.HEAD;
var requestLoader:URLLoader = new URLLoader();
requestLoader.load(urlRequest);
It works if I use either POST or GET, but not HEAD, PUT or DELETE.
I don't know how to solve it or if it has been deprecated.
According to the docs, the constant is still valid but in the first line it says that it is only to distinguish between GET and POST.
Edit:
Finally I ended up doing the request in Javascript and calling it from actionScript. Maybe it is not a great solution, but it works fine.
I have a quick question regarding POST file uploads in ActionScript 3. I am trying to upload a ByteArray from memory via POST to a server. I'm using the URLRequest class to send the data, and URLLoader because I want to monitor the progress. The relevant sections of code follows:
var uploadRequest:URLRequest = new URLRequest("http://127.0.0.1/upload.php");
uploadRequest.method = URLRequestMethod.POST;
uploadRequest.contentType = "multipart/form-data";
uploadRequest.data = myByteArray;
var uploader:URLLoader = new URLLoader;
uploader.addEventListener(ProgressEvent.PROGRESS, onUploadProgress);
uploader.addEventListener(Event.COMPLETE, onUploadComplete);
uploader.dataFormat = URLLoaderDataFormat.BINARY;
uploader.load(uploadRequest);
The problem is that I've set my callbacks to trace the upload progress, and the bytesTotal property of the ProgressEvent is always 1960 (the size of the request minus data?), even though the actual data is around 20MB and no file is uploaded even after the Complete event fires.
I've verified that upload.php functions correctly with a simple html form, and I can verify that myByteArray contains all of the data in question. Can anyone tell me what I'm doing wrong?
Edit:
I've attempted a couple of new things that I thought I should mention. The first is setting the content type to application/octet-stream instead of multipart/form-data, which had no effect other than increasing the number of bytes to 1964. I also checked the Apache error log and found the following text repeated a lot:
PHP Warning: Missing boundary in multipart/form-data POST data in Unknown on line 0
I'm guessing that Flash isn't formatting the HTTP request properly for whatever reason. Given that I created a FileReference that makes use of the same methods I set for the URLLoader to upload a file from disk, and got the expected result: the bytesTotal property matched the file size and the file was uploaded correctly.
Working from that I found a page in the Adobe developer docs that mentions uploading data to a server using FileReference.upload() by setting the data parameter of the URLRequest, so I tried the following code:
var uploadRequest:URLRequest = new URLRequest("http://127.0.0.1/upload.php");
uploadRequest.method = URLRequestMethod.POST;
uploadRequest.data = myByteArray;
fileRef = new FileReference;
fileRef.addEventListener(ProgressEvent.PROGRESS, onUploadProgress);
fileRef.addEventListener(Event.COMPLETE, onUploadComplete);
fileRef.upload(uploadRequest);
Which resulted in the following output:
ArgumentError: Error #2127: FileReference POST data cannot be type ByteArray.
I'm really stuck here. Any suggestions would be appreciated!
You should add more info to the "Content-Type" header:
uploadRequest.contentType = "multipart/form-data; boundary=<<boundary here>>";
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.
