Actionscript 3 :: Making Requests From Flash For URLs With + Signs In Them?
Aug 20, 2011
I am hosting images on Amazon S3 and using them in my Flash application. My application receives signed S3 urls that point to the images in S3. The URL looks something like this (line breaks added for clarity):
[Code]...
The problem here is with the + sign that can occur in the Signature. If I send the + sign as-is, then the browser thinks that it's a space, as it should according to the URL specs. Really, S3 shouldn't use + signs for this reason, but it seems to be something they overlooked. Normally this isn't a problem since you just replace the + sign with a %2B. However, Flash has some default behavior that makes this difficult.
From what I can see, the URLRequest object is setup to always encode URLs as if it was passed through the encodeURI function. I don't see any way to turn this off. Unfortunately, encodeURI doesn't encode + signs, but it does encode % signs.
This means that if I leave the + sign in there then Flash leaves it alone and S3 thinks I have a space in my URL. If I use %2B then Flash turns it into %252B, due to encoding the
The main top section of the site is a little Flash thing that has buttons as links to different areas of the site. All of that is well and good, but whenever I click those links, it has to reload the entire page (including the Flash app) when only the bottom part changes. This isn't really a huge issue, since everything's real small, but it's kind of annoying.I vaguely remember "fixing" this behavior using AJAX during my web programming class, but that was just straight HTML and Javascript, no Flash players to muck around with.My question is, how do I overcome having to reload the entire page when someone clicks a link from the Flash object? Is there some nice way I can call something other than getURL() to achieve this effect?
I have this odd situation, let me provide some background: - I have SWF and PHP files on a shared host, along with a MySQL database - I'm using urlloader requests to interact with the database via the PHP files.Everything works for me as expected. However, the end user is having trouble. Basically, none of the urlloader requests actually make a request - I'm basing this on all of the *.php requests in the access log from my IP, and none from his IP. I had him load one of the PHP files directly, and it came up fine, so I've ruled out firewall/security problems on the OS level.
Now - what could possibly cause this? He has 3 machines running XP and win 7 (all with the same issue), and he's using IE8 with the latest flashplayer. I've set up an XP virtual machine with IE8 and also the latest flash player and it works fine. I've also tested on a separate laptop running Vista. I've also tested with chromium and FF3 under linux and FF3.6 under XP (flashplayer versions 9 and the current 10.x) and everything works hereI've tried a crossdomain.xml file allowing from *, allowing from the domain where the files are hosted, and no crossdomain.xml file at all.
I'm having a problem that I'm not sure is necessarily tied to the Flash, but I don't know what the root of the problem is yet.I have a SWF that connects to a socket using the Socket class. This works fine.I'm also making (jQuery) $.getJSON() requests to load certain page data. This works fine.
However, when the Flash socket is connected the Ajax requests stop being sent. By this I mean that it seems that the HTTP requests being made are stored in a queue while the socket is connected. As soon as I disconnect from the socket the HTTP requests continues to load fine. The HTTP request never times out (as it's not even being sent to the server), but just hangs there waiting...until I close the socket connection.
I've verified both in the jQuery and Adobe docs that both the Ajax (JSONP) requests and the connections using the Socket class are asynchronous, so I'm really confused as to why the socket connection would block the HTTP requests.
It's possible in plain HTML to wrap pieces of text in spans or tags that can make it easy to style them later. For example, if I wrap "part can be styled" in a span wit class stylable, I could define my own style later for it. This <span class="stylable">part can be styled</span> later if needed I'm new to actionscript, and I'm wondering if something similar exists for actionscript/flex?
so i updated a site and now the input text part on my form does not input numbers or signs which i need the @ to work for the form to work and i tried to fix it on cs4 and it will not work because its not the same format since i updated it from cs4 to cs5 and now i cant go back. How do i get the numbers and signs to work now?
Is there a way to make the user draw the signs "greater than" > and "less than" < with the mouse and after that I can find out which of the signs it is.
I am trying to load html into a text box from a website. when i load to the text box, everything goes fine except that it is loaded as something that looks like this:
I know this might be a dumb question.. I somehow switched on paragraph signs () in the actions-window and they appear after every line break. I can't figure out how to make them disappear again.
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.
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?
As you might know, browser's security model does not allow a script loaded in a page from http:[url]... to make cross-domain requests (no AJAX calls to any other domain other than url...).The Javascript file itself could have been served from a different domain altogether (url....) and that is irrelevant. This is the Same-Origin Policy.
Flash also has something similar? But does Flash treat the origin to be the HTML page where the .swf file was loaded or origin is the domain which served the .swf file?
So http:[url]... loads a .swf file from http:[url].... Now .swf can load resources only from [url].... or only [url....? I'm assuming there are no cross-domain.xml files setup on either [url]....
First off, I'm trying to fix something that I didn't build to begin with and the guy who's project it was assures me it was working fine when he left, although a version I haven't touched since he left seems to have the same issues. I'm also a bit new to programming in general so let me know if I've left out important information in my first post and I will try to add more info.
I have a flash application hosted on-line that acts as a client for a server application written in Delphi. Most of the communication is done using sockets, which work fine. Uploading data files and downloading results files is done using HTTP requests, which work fine as long as the user is making use of an instance of the server on another computer. However, if the user has the server application installed on their own computer and attempts to use it specifying localhost as the url, the socket communication still works, but the HTTP requests don't.
All the socket based communication works fine and, when it is not on the localhost, all the HTTP requests work fine as well, which is why this is so mystifying to me. I've tried changing the flash cross-domain policy file that the server dispatches to be completely permissive, all ports, all domains, all http-request-headers, and still no luck. The Flash app will sit waiting for localhost indefinitely most of the time until I close the server application, and then give this error message:
I am finding that if I load Flash from a HTTPS page [URL] and try to make a request within ActionScript 3 to [URL] the request does not go through. Same goes for the opposite (accessing https from a http-loaded flash script).
The request is failing, the requested data (passed from a PHP script) is not loading.
Now at first I assumed the trouble was with cross-domain policy files, but I have fixed that issue (I think).
Is there any security policy in Flash (CS5 btw) on HTTP vs HTTPS requests based on where the script is loaded from?
I have a Flash based game for the browser which sends users' scores to a php backend script which stores the score and the user id in the database.
Now I have a url like www.example.com/update.php?score=200&uid=234
The problem is that this is very much exposed to an intelligent user, and he can use this url to store whatever score he wants in the DB. Also there's no real user authentication, and I don't intend to have one either, because it's really a tiny game.
How can I stop someone from calling the above url and updating his score on his own.
I'm using YUI file uploader based on flash, and the flash requests host/crossdomain.xml file. I'm requesting localhost and it requires this file. I was using this before and I have never had this problem and I've never had this file on my server.I've never used any adobe technologies, could please anybody tell me if it is possible to turn it off somehow ?The problem is that I can't have the file on my server, at least at root location...
By far the weirdest thing I've ever seen. On some machines (!) IE (!!) attempts to load an SWF file via HEAD request instead of GET. This happens only when the page is running in Facebook IFRAME application - when running solo works fine. Naturally, on FF and Chrome everything works just fine. The SWF is embedded using jSWFObject. There's no visible common feature to the machines which experience this problem - laptops, desktops, XP, Vista, 7.
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.
a client hosts numerous sites at MT, I've built a few Flash sites that exist on his server. For some reason, the server is over-running due to an internal loop that is basically the domain requesting itself over and over. can this potentially happen via the player itself somehow making numerous requests.
How would you add a target="_self" function onto the buttons in this actionscript (as3) I need the buttons to open within the same browser window and not a new (_blank) window:
skype_btn.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownHandler); function mouseDownHandler(event:MouseEvent):void { navigateToURL(new URLRequest("skype:mySkypeIdentifier")); } email_btn.addEventListener(MouseEvent.MOUSE_DOWN, mouseUpHandler); function mouseUpHandler(event:MouseEvent):void { navigateToURL(new URLRequest("mailto:myEmailAddresss@myDomain.com?subject=rts Esolutions enquiry")); }
I'm building a flash app that gets rss links from a list but then I need to retrieve the rss feed from the rss link to work with in flash. I did this locally using a proxy.php wich works on all types of urls.
But on the server it only works with urls ending in .rss but not when it's a redirected url like .xml or other feedreader urls. How do I retrieve the rss from redirected urls on servers? Little sidenote, I made a test using a php form to call this proxy.php file that I made and when I use the urls that don't work in the flash app it does retrieve the rss feeds.
im trying to find info about giving sections of my flash websites different urls.[URL]How do i code it so that a url can take me to a section of a flash website?
I've created a flash intro for a website and I have it setup so that in the first frame of the intro it opens a popup window, and then in the last frame it opens the actual site in the same window as the intro. Right now when it hits the last frame it opens up the popup window again also! Ack! The code I've used for opening the popup window is:var url:URLRequest = new URLRequest("player.html"); navigateToURL(url, "_blank");
the code used in the last frame to move to the site is:var urlReq:URLRequest=new URLRequest('index2.html');navigateToURL(urlReq,'_self');
I'm guessing that it has something to do with re-using the same variable name. I tried changing the code in different ways on the second window opening but still had the same result, or broke it opening up any pages at all. I've also tried moving the two code snippets to different layers. I'm thinking there might be a few ways around this too such as if there is a way to trigger the popup window, and then have the intro wait x seconds and then opens the main site or something, but I have no clue how to go about doing any of this. have the site in question in a temp location currently and it can be viewed here: [Url]
Im using Swishmax and I can't seem to make a url open in my flash site(so it doesnt open as a pop up but in my actual flash site) So basically that it opens in a designated space that I made for it on my site. I know that a tuturial for this exists on this site but i just can't seem to find it.
I've noticed that a number of Flash sites have urls such as [URL] which gives the ability to return to a specific area (in this case "services") of the site rather than staying on the homepage each time you go back to the page. As you navigate through the site the url changes to reflect where you are in the swf.
