I have a flash game and get updates after pressing a button. Only a table inside the flash gets updated and the changes are not shown in the html source (well, its flash after all). Logging with Fiddler shows first one encrypted package (containing all data of the table after decoding with Fiddler) followed by 16x json packages (single entry of the table).
What i want to know is how to get those single packages in Delphi.
I do not want to alter the data, i simply want to read them. I cant make any changes to anything (webserver, flash, etc).
You could try proxying like Arioch suggested. I'm not too sure it would work, though.
If I were to do it this would be how:
Create a shared library in C (or C++) where you can hook up various dest/origin addresses and ports using WinPcap
Have it call your application when something get's caught
Process/manipulate the packet data as needed
Pass it on
Unfortunately there's no working WinPcap "headers" (or components) for Delphi, so there's no other way (other than porting all the headers to Delphi ...).
Here's a tutorial on how to use WinPcap.

I've been wondering how to fetch the PlayStation server status. They display it on this page:
https://status.playstation.com/en-us/
But PlayStation is known to use APIs instead of PHP database fetches. After looking around in the source code of the site, I found that they have a separate file called /data.json.
https://status.playstation.com/en-us/data.json
The content of this file is the same as the index file (for some reason). They use stuff like {{endDateTitle}} and {{message}}, but I can't find where it's defined, if it's pulled using a separate file or just pulled from a database using PHP.
How can I "reverse" this site and see if there's a API I can use to display the status on my site?
Maybe I did not get the question right, but it seems pretty straightforward.
If using firefox, open Developer tools, Network. Reload the page.
You can clearly see the requested URL
https://status.playstation.com/data/statuses/region/SCEA.json
It seems that an empty list as a status means "No problems" (since there are no problems I cannot verify this assumption. That's all
The parenthesis {{}} are used by various HTML templating languages, like angular, so you'd have to go through the js code to understand where they get updated.
We have a SPA web application that we're trying to convert into a WinJS project as a native Windows Store app. For most part, the Javascript is working except for DOM manipulations deemed unsafe.
One thing that does not appear apparent is, how can the start page of the app (e.g. index.html) be supplied with query string and hash parameters? Our site main page is designed to behave differently based on parameters.
e.g. index.html?contextId=xxxxx#enviroment=xxxxx
I tried adjusting the value in package.appxmanifest to no avail. It will throw errors on query strings, and hash parameters will silently not persist.
UPDATE: Project background
A brief about what our app does, and then why the above naive desire won't work and the answer below how we went about this issue.
Our web app is a highly-dynamic data-driven application that completely relies on data to figure out what to render. Therefore the ?contextId=xxxxx parameter is so crucial as it tells our system to load the data which further informs what kinds of visual components to load and it goes on recursively to form wildly different UIs.
We were looking to therefore find some means to supply these parameters like traditional command-line parameters to the same executable to produce different UIs. And thus different "apps" by mere changes in those parameters. Like a "config transform" mechanism for web.config in ASP.NET web projects, that would be most welcome.
However further testing showed it is not possible; a single Windows store app project has a GUID that is supplied into the packaged app bundle. Building the same project multiple times with different "build config" would just mean overwriting a previous installation since they are the same app with increasing version numbers. The answer details how we went about this.
Windows Store apps don't work with URI parameters when launched from their primary tile. In that case, you should make sure that the app defaults to suitable values, e.g., if you were thinking to supply defaults in the manifest, then default to those in the app's activation handler for the ActivationKind.launch case when eventObject.detail.arguments is empty.
There are two other ways to launch an app that can supply other arguments.
First is to launch via a secondary tile. When you create the tile from the app (which is subject to user consent), you supply the launch arguments. In your activation handler, for ActivationKind.launch, those args will be in the eventObject.detail.arguments property.
Second is to launch the app through a URI association. You use a custom schema for this, which is declared in the manifest. The app will then see ActivationKind.protocol and eventObject.detail.uri will contain the full URI including any parameters. A URI launch can be done from another app, by entering the URI into a browser address bar, or through a shortcut that a user could configure on the Start screen.
The first step is to convert our Windows (8.1) Store project into a Universal app structure, which would then spin off a separate Windows Phone WinJS project (this is nice when we wish to target Windows Phone later) and a shared project.
Practically everything from the Windows Store project is moved to the shared project (including default.html or index.html). What remains in the Windows Store project is a customised config.js carrying the parameters
window.customWin8 = {
contextId: xxxxxxxxxx,
customParam: 'xxxxxxxxxx'
};
The downstream modules that sense for query string/hash parameters would then fall back to this alternative object if it exists to pick up the data it needs.
Now, for every differing app we wish to deploy, that would for now seem to require a separate Windows Store project so it gets its own GUID and won't conflict with other apps. All these projects would reference the very same shared project thanks to the Universal structure Visual Studio affords. The only down side is it seems Visual Studio 2013 does not have a direct UI method to make this referencing to the share project and has to be hand code into the jsproj file.
<Import Project="..\Common.Shared\Common.Shared.projitems" Label="Shared" />
With this adjustment they can all build and package with their isolated "build config".
I have a drupal site that is being used strictly as a CMS that produces JSON feeds using services and services_views, which are consumed by a separate site. What I would like to do (and I have a working proof of concept of this) is allow for a "live preview" on the real site, by intercepting the node form preview / submit, encoding the node as JSON, and loading a special page on the live site that consumes that JSON and displays the page accordingly.
The problem with this JSONized node is, it's different from the JSON being produced by my view (using services_views). My end goal is to produce JSON that is identical for both previewed and non-previewed objects, without having to maintain separate output methods (I could easily hand-customize the json but then when my view for the public api changes I have to make the same changes to the preview json. Trying to avoid this).
I'm looking for feedback on this approach. Is what I'm attempting even possible? The ideas I've been able to come up with so far are:
being able to (conditionally) drive my view with data from a non-databse source
sneakily inserting data into the view object during one of the stages of execution? Kludgy but I'm not above that :)
saving a "clone" node (or revision?) of the node being previewed and let the view use that to display the preview JSON?
Maybe this is the wrong approach altogether and there's something better? (Trying to intercept and format the services output in my module... maybe avoid services_views altogether?)
If anyone can offer some advice, insight or opinions on how to best proceed here, I'd be really grateful.
in a custom module, you could set up a page that grabs the json output from the view page.
$JSON = file_get_contents($url);
that way the preview stays bound to the view, even if the view changes.
First I think it's not an easy task what you are trying to achieve. So before all, good luck.
I think you could intercept the node submission data, then create a node programatically, then render that node, and then export the rendered node to JSON. Inmediately after you get the JSON, delete this node, because the programmatically created node is only for preview.
This task could be more CPU demanding but think that previewing content exactly as the content will look is difficult.
Your rss feeds that your site reads could be filtered with some parameter to avoid programmatically created nodes (prewiew nodes), despite these nodes will be available for a very short time.
Is there a way to check file size on the client (without the use of ActievX which also errors out), before it is passed back to the server? in asp
In ASP? No, by definition. Active Server Pages can't do anything before they get a request from the client.
There is a draft File API that will allow you to perform this sort of check using client side JavaScript. The Mozilla Developer Network has a guide on getting information about selected files. Once you have a reference to the file, you can just access its .size property.
Note that since the specification is a draft, it is rather new and subject to change. This one is very new and thus has [very limited browser support](http://caniuse.com/#search=file api).
You might also be able to achieve what you want using a Java applet or Flash (the latter of which would be better supported).
WHat is the standard method for say a server to update an already loaded SWF on the client browser, i.e. something analogous to how an html page is partially updated via ajax (though I don't know a lot about ajax yet either.) Would the mechanism be the same if user-initiated.
I assume the .SWF should have public functions that can be invoked, then you'll use javascript to access the swf from the html page its in, then invoke a public function of that swf.
Just the specific terms or functions I need to search for to get a primer on this would be great.
ALso, How would one go about testing the public functions of an swf that is already loaded in a browser (wihtout having a full Adobe devleopment suite for example).
This is quite a vast subject actually. This is the whole RIA concept. Flash can look after itself in terms of communicating with a server , you don't necessarily need Javascript. You only need a server side language to communicate with.
Since it all can happen within the swf , public functions don't really come into it. A User initiates an action in the movie that triggers a call to a remoting service which in turn sends a response which consequently updates the movie.
A few areas you can look into, in no particular order:
Flash PHP communication
Zend Amf Server ( Zend Framework )
http://framework.zend.com/
For testing purposes , try MonsterDebugger
http://gotoandlearn.com/play.php?id=109
Edit:
Flash can use PHP to retrieve a XML , then parse the XML & change the data inside the SWF according to the data retrieved in the XML
http://gotoandlearn.com/play.php?id=90
In case of a link, the concept is a bit different, because depending on the type of link this may cause a page refresh. The approach in the above tutorial could be user initiated by clicking on a swf element, entering text in a text input box etc... this is what I meant by the RIA concept. It's quite standard now in Flash that user interaction will introduce changes in your SWF by making calls to the server.
