Flash :: Javascript Upload In Spite Of Same Origin Policy
Apr 20, 2010
Can one upload files to a domain other than the domain a script originates from? For example, suppose you're hosting files on [URL], and you want to upload files to [URL], would the following script violate the same origin policy (using uploadify):
Is it possible to pass file names from a running Flash application, which only purpose is to enable multiple-file-selection, to a JavaScript application which handles upload of all files to the server?I have examined various Flash upload solutions (like SWFUpload, Uploadify, etc.) and none of them meets my needs. I want an easy to implement solution (like Uploadify) which also lets me specify various parts of the HTTP request.
The reason I need this is because my upload form uses session cookies (for user authentication) and an CSRF token both passed to the server when uploading files.Is it technically possible to pass filenames (+ paths) to a JavaScript application which then handles the upload?
I'm looking for a flash widget that allows users to record their audio and then send it to the server.
There are a few similar questions:
Record Audio and Upload as Wav or MP3 to server
They advocate using Red5 or flash media server.
Shouldn't it be possible to record locally on the user's client using the codecs that the user already has and then upload the resulting file to the server, rather than say, process the and record the stream on the server itself.
I am trying to create a multiple file upload flash application to be called from an External Interface, but it isn't working.
AS3:
var fileRef:FileReferenceList; ExternalInterface.addCallback('selectFiles', showDialog); function showDialog()
[Code].....
When I run the script and comment out the fileRef parts and uncomment the alert call, it shows the alert, also when I comment out the ExternalInterface call, leaving only the fileRef parts, it shows the file upload dialog.
When I run it as intended, I get the following error:
use CDATA text when passing text to TextFields, if those texts contain fancy stuff... like line breaks.Anyway, I did exactly that, and now have the problem that each line break that is inside the CDATA tags comes out as a double linke break.If for example the text in the XML is like this:
Code: <txt id="TXT_linkcopied"><![CDATA[Link is copied]]></txt>
Is there any "mainstream" library used for this purpose? Commonly spread, well maintained, documented etc.I found these (using flash):
Uploadify - not many releases, latest 12/2010, no documentation (!) SWFUpload - latest release 03/2010, documentation fancyupload - looks buggy.
phpfileuploader - looks heavyweight, and looks commercial (?) I cannot read the licence (you can download it but are you allowed to use it forever without paying?) plupload New version of pure javascript (no flash) Valums' ajax upload claims to handle file size limit and progress bar, which is quite suspicious to me: these features require to guess the file size before the upload, which seems impossible in javascript (look also here). Or can it work?
On a webpage, is it possible to split large files into chunks before the file is uploaded to the server? For example, split a 10MB file into 1MB chunks, and upload one chunk at a time while showing a progress bar?
It sounds like JavaScript doesn't have any file manipulation abilities, but what about Flash and Java applets?
This would need to work in IE6+, Firefox and Chrome. Update: forgot to mention that (a) we are using Grails and (b) this needs to run over https.
I'm trying to upload a photo on Facebook using Javascript SDK. In particular I generate a base64 encoded bytearray from my Actionscript3 app, I pass it to Javascript file using ExternalInterface, and from that I decode the bytearray and I try to upload to FB. But it give me this error: {"error":{"message":"(#324) Requires upload file","type":"OAuthException","code":324}}
I tried to upload an image simply from url, and in that way it goes well! This is my Javascript code: upPhoto:function(photo) { var img = F.decode_base64(photo); FB.api('/me/photos', 'post', { message:'test', fileName:'test', [Code] .....
I'm looking for a multiple file upload button. the ones I've found areswfuploaduploadifyI want to integrate it in a django app. ATM the only one which is working without any problems and is in widespread use seems to be swfupload.
I want my file upload to be very simple, and what could be simpler than just a single button. The requirements are that you should be able to upload multiple files at once. It would definitely be an advantage if I could add file format filters as well, and design the button by myself (including the hover event).
I searched and found Plupload, which seemed to be awesome with the easy setup and functionality, but I can't quite figure out how to create my button; I've only found their Custom upload, which prints out the file names and requires at least one click on another button before it's done (and I can apparently not add any hover-attribute). I tried to edit the JavaScript to make the form be sent after all the files had been added, but failed.
Does anyone know the file upload hack for Flex, which will allow files to be uploaded to authenticated web services via multipart form post? In this bug report from the Adobe site, a user reports: Flash isn't cross-browser compatible if this feature only works via Javascript hacks. So far, I've been unable to craft such a hack. I'm unsure what to do next. Here's what I've tried so far (all have been unsuccessful or impossible). Set cookies on url Pass cookies to Flex URLRequest Create hidden html form in javascript to post file
Basically I'll be working with large XML files (approx. 20 - 50 MB). These files needs to be uploaded on a server.I know it isn't possible to touch the files with javascript, nor to implement HTTP compression on the client-side.
My question is that if any solution exists (flash / action script) that compresses a file and has a javascript API? The scenario is this:
Trying to upload 50 MB XML file Before upload a grab it with Javascript and send it to the compressor.Upload the compressed file instead of the original one.
I'm looking for multiple file upload component with alternative ways.I need HTML5, Flash and normal upload support, depended by device.I don't like FancyUpload, because it uses mootools and mootools is very big library.Also I can't use jQuery, because I'm writing on Ext js and it's not good idea to use two big library like jQuery and Ext js.
I have an upload form for an image. The user clicks browse and selects a file. How can I get the image dimensions the moment the user selects the file (before the file is even uploaded to the server). It obviously has to be something client-side with maybe javascript/jquery or flash/flex (prefer js//jquery though), but can either of them do this? This is the code I'm using to tie into zozo's getImgSize() function, but it gives me 0*0 as size.
I'm looking a quick way to add an (multi) image unloader with client side crop to an ASP.NET MVC site and for some reason the search seems to be much more complicated than I thought upload image (can be via form post or custom, just has to work with ASP.NET)custom crop possibility before upload (preferred) multiple images at once It doesn't matter if js/jquery, silverlight or flash is used, it just has to work, its an internal application and I can force people to have the necessary plugins installed.
I have a picture upload function in my flash and when I upload a picture I lose focus on the flash. This results in that all my listeners disappears. I cant click buttons, use dragbars etc. This only happens in FF. Im using flash player 10 and Snow Leopard. ive tried to get the focus back by sending a call to javascript:
I am creating flash uploader and want to start 10 uploadings at time.But flash upload only 2 files on domain at time, other references wait for something.In IE with ActiveX Player limitation is about 6 files at time.Is there any ideas how to change this limitation? For uploading I need to use FileReference.upload without creating URLRequest object from file data.
I'm looking for a script which allows the creation of a custom selection on a image online. This step is just after an upload. As a picture is worth a thousand words:
I've been trying to configure uploading and I've been getting an error 500.I'm running a server on Apache2 with php5+ installed. I'm curious to why i keep getting an error.[code]I added those to my .htaccess file
I think I did this before but can't find the code. Flash as many other graphical frameworks use the top-left corner as the coordinate origin (0,0) because it's how the underlying memory model is by convention. But it would be really simpler for my calculations if the origin was in the center of the stage, because all the game revolves around the center and uses a lot of trigonometry, angles, etc. Is there some built-in method like Stage:: setOrigin( uint, uint ); or something like that?
How do I move the origin point, or zero point, of a MovieClip to the same origin point of the stage without scripting in Adobe Flash CS3?
Example: While I'm trying to move objects within a MovieClip, the origin point is at (stage) 200,-300. This means that when I put objects in a MovieClip, the objects' X,Y coordinates, as displayed in properties, are off by that much.
This point is way off the edge of the stage and I'd like to move it back to the stage's origin point so that my X,Y coordinates are meaningful.
Is it possible to get the target/origin of errors and error events when using UncaughtErrorEvent.UNCAUGHT_ERROR ?
I am logging runtime errors of users using a complex flash app and would like to know where things are failing. The target of the UncaughtErrorEvent is tracing as LoaderInfo (which is, I assume, because it is also kicking out the UncaughtErrorEvent) and the target of the ErrorEvent is null.
How to I get my security policy working? My parent swf parses an XML doc and loads 2 children. It throws a 2148 security error, and only works in the Flash IDE. PARENT SWF 'I put it at the top of my code. That seemed like the proper event flow' flash.system.Security.loadPolicyFile("crossdomain.xml"); I've referenced my security file from my swf. I Also published my parent swf as 'network only' and put all the crossdomain.xml and everything else in the same folder. I need to click on the animations and have them place from a local computer at a kiosk. POLICY FILE 'Used"*" since there's not URL, it's all local'
In my Flash app, I'm connecting to my server like this:
Security.loadPolicyFile("xmlsocket://example.com:12860"); socket = new Socket("example.com", 12869); socket.writeByte(...); socket.flush();
At port 12860 I'm running a socket policy server, which (according to this document) correctly serves up my policy like this:
[Code]...
I get no security warnings, which I used to get before the policy server was in place. Still, the connection to port 12869 doesn't work. It's made (I can see with Wireshark and on the server), but no data is sent by Flash. It might be worth knowing that the SWF itself is served from example.com as well.
So, this is a copy of another post I made, but I get a sneaking suspicion I put the post in the wrong forum:[URL]..The summary:
The Socket class in flash player sometimes, for some users (across all sorts of OS and Browsers) will not ask for the policy file from port 843 first, but instead will go straight to the port of the outgoing request, which in this case is our game server, who doesn't really understand the request.
In every case so far the user *is* using the latest version of flash too, so it's not an issue without outdated policy methods, which would have been my first guess.For most people it works just fine, but I posted a log in the thread for one of the non-working players. It's pretty mysterious, and I haven't found a fix yet... though I'm going to experiment with some work arounds.
I was looking around but couldn't find it where can I add the cross domain policy of Adobe in Apache server. Because without it, its not letting me access my XML on another server.
I'm really sick and tired of facebook's crossdomain.xml , finally got it working for loading pictures from the server. Now I need to load variables from my app using flash. I'm getting this error.
Basically I'm using Flash to connect to a Java server.Despite my Java application replying to the <policy-file-request/>, in the Flash debug log it lists (not sure about the order as there are lots):
Security Sandbox Violation * Connection to 192.168.1.86:4049 halted Warning: Timeout on
Has anyone been able to successfully implement a service to serve the required socket policy file to FlashPlayer?I am running the Python implementation of the service provided by Adobe at
