Re: [Vala] Looking for an example on how to get the data from a web form (when using a Soup-based server)

Thank you very much for your example !

It is very much appreciated.

Sincerely,
Serge.

You can look at my example, its not in the best shape but worth looking at.

As a big note libsoup's way of handling Post/Get is horrible.
Uploading files and getting the post as well as get parameters is
blah.

Hi,

I am looking for a slightly more complete example than the one from the
Vala tutorials on "Soup".

More particularly, I am looking for a snippet that would show how to

get

(and possibly decode) the data sent via HTTP from an HTML web form (in

a

browser) to a (Soup-based) server.

Thanks !

Serge.
