Qt DevNet Web Service API
-
[quote author="ZapB" date="1300203182"]Thanks Gerolf. I have just read both of those and have tried the API (using browser). Now to learn how to use QJson to parse the responses and get a proof of concept example working...[/quote]
I like the idea. :) I have been toying with the idea of some integration into the "KDE Social Desktop":http://techbase.kde.org/Projects/Social-Desktop resp. into the "Open Collaboration Services":http://www.freedesktop.org/wiki/Specifications/open-collaboration-services as well. It never really materialized though.
Currently, I am waiting for some proper documentation for the existing API from the developer who wrote it. As soon as I have that I'll make it available on the wiki. Maybe I should nag him a bit...
If you have suggestions for improvements while you play with the API, please let us know. :)

I have had a couple of hours ot play around with this today. Here is the result of my tinkering so far:
!http://gallery.theharmers.co.uk/upload/2011/04/09/20110409200932-876ce30f.png(QtDevNet Profile Details)!So far my simple test harness just uses QNAM to login to QtDN and then uses the web api described "here":http://bugreports.qt.nokia.com/browse/QTWEBSITE-137 to query my profile details. The main widget is a declarative view in which I have a simple qml scene that binds to properties of a C++ Profile object.
Could I put in a request for an addition to the profile api please? It would be very useful if it also returned an entry for the total number of points in this rank. That is the total number of points required to go from Robot Herder to Dinosaur Breeder for example. This would allow me to calculate a percentage towards next level value and show that in a progress bar without the need to hard-code the rank point boundaries.
Next I will start looking at the Unread Forum Posts api and see if I can make another qml component for that. I will also add in support for profile badges. I'll try to find some time tomorrow to make this little code available to anybody who is interested.
Eventually I would like to release a little QML based QtDevNet app for Symbian etc.

If anybody is interested, you can now download my little test harness from my subversion repository. Just do:
@svn co https://svn.theharmers.co.uk/svn/codes/public/qtdevnetclient/trunk qtdevnetclient@
Then build as normal. This project requires qjson to be available. If the compiler cannot find it then export QJSONROOT with the path to where qjson is installed and re-run qmake.
The test harness app now polls QtDN every 60 seconds for an update to your profile which is then relfected in the QML scene.
For now it is just functional. I'll add some bling later ;-)

Good stuff, and a QNAM login. You're on a roll ZapB :)
[quote author="ZapB" date="1302376861"]Oh another api request...would it be possible to have the url to the profile's avatar image returned in the profile call too please?[/quote]
I'll add it to the backlog, no room in the current iteration and filling up fast for the next.
-
It was surprisingly easy - only 453 lines of code plus a little QML so far. If I get something useful going then maybe you'll see a new user-agent string showing up in the analytics soon ;-)
@request.setRawHeader( "User-Agent", "ZapB's QtDevNet Client 0.1" );@
When I finish the next stage I may have some more API requests as that will likely be the much easier option as opposed to scraping fragments from a complete web-page. It will result in a lighter load on the server too.
-
The changes I had to make to make it compile for me:
In qtdevnet.pro, changed the path handling a bit
@
INCLUDEPATH += $$(QJSONROOT)/src
LIBS += -L$$(QJSONROOT)/lib -lqjson
@In profile.cpp, I changed the include for qjson's parser.h:
@
#include <parser.h>
@This way, I can actually make QJSONROOT point to where I downloaded and build QJson.

The only thing you can do at present is to go to the "Application->Login..." and enter your QtDevNet credentials (not included support for OpenID yet) and it will login via QNAM (see the Authenticator class). One slight mystery I have not had time to look at yet is why QUrl::toPercentEncoding() will not encode a "/" character. I have to manually replace that with / later. I'll step into the Qt code later and take a look.
If that works it will start a timer inside the Profile class that polls QtDN for your profile stats once every 60 seconds. The response is parsed using qjson and the properties updated accordingly.
The Profile class is exposed to the QML root context and the qml scene just binds to the properties of it (and one property from the autheticator object which determines if the qml items are visible or not).
It's just a starter for 10/proof of concept at this stage. Nothing fancy. Having said that it will be simple to extend to cover other features that could be supported by a web API.

Just a small update. The login dialog is now handled via QML too (the actual network stuff is still in C++ of course). It's in svn if anybody wants to grab the update. Here's a screenie (no bling-tastic animations yet though).

ps I hope you don't mind me grabbing artistic assets from the site for use in this client. ;-)
