Qt and CGI routines

**jcr** · 27th November 2006, 12:23

Hello,
Is Qt of any help to write a C++ CGI aplication? Or maybe there is something better inside Qt to write routines that can interact with web pages?
Thank you

Yes, it's possible to write CGI program with C++ (and Qt). I wrote one for my last job. CGI programming is essentially string processing, so QString will make the job easier.

Thanks for sharing the experience. Did you use special CGI libraries? For instance, to handle GET and POST data, to output html, or to manage cookies...?

Maybe I don't understand things here but I was under the impression that QHttp handles only the client side of the Http protocol and not the server side. To write a CGI app, I need for instance routines to parse the QUERY_STRING and I don't think it exists in QHttp. As Brandybuck suggested, QString comes in handy at that point but it looks like Qt does not have something specifically tailored for cgi programs.

Parsing query_string is quite easy if you have QString around. Just split the string around & and then around "=". You can then even construct a QMap that will keep all the arguments.
