I have flash (AIR) application running on a single controlled system (there is only one computer running it and nobody has access to it).I will host some files on Amazon's S3 and I need to make sure that only my flash app running locally on that computer can access those files.I'm wondering what the best (most secure) approach would be for doing this.My initial thought is to make the files on S3 private and store the secret key on the local computer running the flash app. Then when I needed to access the files from flash I would send out an authenticated query string with some expiration time. The only problem with this is that I don't know how to generate the S3 signature in flash. Also I'm a little skeptical about storing the secret key on the flash machine (even though it's a privately owned machine with no other users using it).Is there a better approach perhaps?I have access to a server with PHP, so I could maybe use that as some kind of proxy, I'm just not sure how while keeping the file access secure and not creating a bottleneck through the web server (as opposed to direct access to S3).
I have a class that creates an array from a config xml file. I set a private variable in that class and use a getter in other classes to access the array. The routine that uses the array does the following: - Call the getter and assign the returned value to a local (private) variable tmpArray. the getter is a simple return() using a value that is established in the constructor. - Uses a for loop to itterate over the contents - Uses array.shift() to pop the item in tmpArray
The next time I run the routine, the contents of the array is empty. I'm using the same getter. I implemented the getter when I tried to manage both arrays in the same class figuring that as long as the original array was private (i also tried static), that the value would not change. I have since worked around the problem by moving the routine that fills up the original value from the constructor to the getter. So, consider the following code:
import flash.events.Event; btn.addEventListener("click", btnHandler); var myArray = new Array(); var myTmpArray = new Array() myArray = ["one", "two", "three"]; myTmpArray = myArray; function btnHandler(evt:Event) { [Code] .....
If I create a variable myVar and set it to 1 then set myOtherVar = myVar, the both equal the same value. If I change the value of myOtherVar, myVar is not affected. But using the shift() method changes both the original and the copied array.
Currently I have two classes which are "bullet" and "enemy".There are two instances of the enemy class.Code from an ENTER_FRAME event in the Bullet Class:
The Enemy Class has a private variable called "hits".What do I have to do in order to reduce the hits of the instance of the enemy that was hit by the bullet?
in the timeline I have a dynamic text box named my_textbox: var my_test:main = new main(); my_test.check_DVBViewer(); my_textbox.text = ??Basically the class waits for the callback variable (my_msg). The problem is: I need to set the dynamic textbox text to my_msg variable. How can I access it? I know I can access a public var in the timeline with functioname.variable but I can't define a public var inside a function, right?
there are classes definitions where all their methods are private my question is why are they private, because i've tried a code wherein i changed all the private access modifier to public and nothing changed!
what if you make an instance of that class with all its method private, how are you be able to access that on another class. coz i know private methods are only accessible to the class where they are declared! will the instance of that class be able to access the superclass's private methods!
on private variables, it's still not clear to me as to why make a private variable and then use a getter and setter, when you can simply make it public! are these variables called static?cause on the way i understand it private functions and private variables are static?
My website allows users to upload photographs which I store on Amazon's S3. I store the original upload as well as an optimized image and a thumbnail. I want to allow users to be able to export all of their original versions when their subscription expires. So I am thinking the following problems arise.Could be a large volume of data (possibly around 10GB)How to manage the download process - eg make sure if it gets interrupted where to start from again, how to verify successful download of files.Should this be done with individual files or try and zip the files and download as one file or a series of smaller zipped files.Are there any tools out there that I can use for this? I have seen Fzip which is an Actionscript library for handling zip files. I have an EC2 instance running that handles file uploads so could use this for downloads also - eg copy files to EC2 from S3, Zip them then download them to user via Flash downloader, use Fzip to uncompress the zip folder to user's hard drive.
Okay so you've got your private vars in your AS2 Class, you think they're all safe right? Wrong.
Doing a trace(MyClass.myvar); will spit out an error that the var is private and you can't touch it.
But a trace(MyClass["myvar"]); will work perfectly fine. You can use it normal, without any setters getters outside the class.
Is there a way to protect against this? I think this is a huge security flaw. I know it's simple OOP, but a private var in an object should have rules.
I'm scraping a website in Flash, writing in Python. I can see in Firebug that the page loads its Flash file and then some background data in an .asmx file. The background data is what I'm interested in - so how can I get hold of the .asmx file? I already know what it's called. I can't get at the .asmx file directly, but can I grab it using Mechanize?
i'd like to know if its possible to save information obtained from users to files if the user is accessing the flash file from a cd. I would also like to know how it works if possible. And can the flash file be in .exe instead of .swf?
is there a difference between classifying a function 'private' or 'private static' in a singleton? It seems that they both do the same thing. Maybe some difference in performance?
I've written a little OSMF player that streams via RTMP from Amazon Cloudfront. There's a known issue, the mp3 duration is not correctly readed from metadata and thus the seek function is not working. I know there's a workaround implying the use of getStreamLength function of NetConnection, which I successfully implemented in a previous non-OSMF player, but now I don't know how and when to call it, in terms of OSMF Events and Traits. This code is not working:
I have a flex 3 app that is attempting to load images from Amazon S3. The images fail to load, so I fired up debug mode. In debug mode, the images load, but I also get the following output in the debugger[code]...
I have created a live stream using Amazon Web Services and Adobe Flash Media Server 4.5.AWS provides me with both a .f4m and .m3u8 file, to use in and tags, respectively.The .f4m loads fine on my desktop browser, and the .m3u8 file loads fine on my iOS device. However, my Android devices will not load either file.What code/solutions are there to get this to play on Android devices?
I've been trying to set up an instance of Flash Media Interactive Server on Amazon Web Services for an AVChat (avchat.net). I signed up for the service here:[URL] I have some simple questions on getting it started --- namely: do I create the FMIS instance myself now that I've signed up, or do I need to go ahead and create it? I see under the EC2 tab I can create an instance under 'Community AMIs' for adobe-flashmediaserver-useast/fms-4.0.1.8011-centos-5.5-ami-1.manifes t.xml Is this what I want? I realize this is a bit of a noob question.
once installed what I'm trying to do is to add a folder for AVChat into /opt/macromedia/fms/applications/ ([URL]). I am assuming that once I do have this instance running, I can move/modify files on the server instance.
I have just started using Adobe Flash Media Server on Amazon Web Services. Does anyone know how can I monitor server statistics such as the number of active connections? I have connected using SSH to the server but I cannot know what to do from this point on?
I've been thinking for a long time about working on a multiplayer game in Flash. I need updates frequently enough that ajax requests won't work so I need to use a socket server. The system will eventually have enough objects/players that I would consider it an MMO. I would like to set up a scalable system on Amazon's EC2. (Which probably effects my choice of server) This architecture would hopefully allow the game to grow without many changes over time. (Using a domain decomposition technique or something similar)
Heres my internal debate:Should I
a. Code my own socket server in C++ or Java?
b. Use the free and open source Red5 socket server for Flash?
or c. Pay the licensing fees and go for Electroserver?
I consider myself a decent developer, but am at an impasse as to what road to go down. I'm not sure if I, could develop/would need, the features of one of the prepackaged socket servers.
I'm also not sure if the prepackaged servers would work well in an Amazon EC2 environment and take full advantage of its features.
So to get around Flash security issues, I have a script to upload files to S3 by sending it to a PHP script on my server which then uploads it to S3 with server-side PHP libraries.
Now, I'm looking for a solution to downloading a file from S3 in the same way. I suppose the best way to do it is to somehow make a PHP script that downloads the file from S3, then sends it back to the Flash client?
But the one thing is, I don't want the file to hang around--I'd like to delete it when the process is done. I suppose I can just have the Flash client call another PHP script on the server that deletes the file after the load is finished.
I have 2 AS files. One is my main file which i have as the Document Class. The other I am trying to get to be a "sub as. file" that will load when the main one loads. The main Class loads pictures through xml. The subclass, (I guess it would be called), loads all of the elements that I need on the stage, such as the forward and back buttons etc.
My main class is
Public Class Slideshow extends Sprite {
//I then put a var within this with as the name of my subclass: public var stageElements:StageElements;
Now, at first when I published the flash it gave me some errors that were in StageElements class so I fixed them and it loads all fine now without errors and the pictures come up but the stage elements do not. I know that my StageElements class works because I have tried it out as the Document Class the .fla uses.
I'm using FlowPlayer to replace an existing FLV player on my site that plays videos from Amazon E3. I have many pages and each should show a different video. For each page, I have a value stored in my CMS that is the "streamName". The stream name corresponds to a flashvars paramenter in the object/embed tags that show the video player:&streamName=my-great-video
On my new player, I'm able to get the video using a URL similar to [URL] How Does Flash (or Amazon???) know to add in the .swf extension? There are several video formats used on the site, and the current player works with them all... But, as I mentioned above, on each page the value store for the video (ex="my-great-video") includes no extension.
So I have a working Flash player using Cloudfront, AS3, NetConnection & NetStream. Works with a FLV, but I need it to work with MP4s. It connects to the stream, and outputs the following:
I'm building a Flash mp3 player to handle streaming mp3s served by Amazon CloudFront (which uses Flash Media Server). I'm using an FLVPlayback 2.5 component to do most of the heavy lifting (I tried an all AS3 method, but any stream automatically stopped within 5 - 10 seconds of playing). When I trace out the FLVPlayback's totalTime property, I get NaN. This is causing the seek bar to simply not work. This only seems to affect mp3s, as when I load an FLV I get a real value for totalTime. Does anyone know why this is happening
I am trying to get my application to load images from my local hard drive. I browse to the image files (no problem so far) by when I select the file to load I get an input/output error. I CAN load images successfully if they are in the same folder (directory) as the Flash application I am creating. Is it possible to load image files selected from folders other than the active application folder?
How do I specify files to be accessed only in a specific folder via a crossdomain? <?xml version="1.0"?> <!DOCTYPE cross-domain-policy SYSTEM "[URL]"> <cross-domain-policy> <site-control permitted-cross-domain-policies="[URL]"/> <allow-access-from domain="*.newdomain.com" secure="true" /> </cross-domain-policy>
Is there any simple way you can access a very short sound file in flash without having to play it in an flv player. its just a ding sound to play when the user hits a button in the presentation.Also is it possible to access an external pic file and then convert it in to a symbol to be used within my presentation.I just don't want to store these files to keep my main swf small.
