GNAT.Sockets: Authentication at HTTP Server

GNAT.Sockets: Authentication at HTTP Server

[Adrian Hoe]

Hi,

How do I connect to a HTTP server (a website) which requires
authentication (Username, Password) with GNAT.Sockets?

I have searched the entire C.L.A. but could not find any clues.

Any ideas?

Thanks in advance.

You can't. I mean GNAT.Sockets does not support HTTP. You can either
directly read/write the HTTP protocol into the socket (see corresponding
RFC) or use AWS (see AWS.Client) which does support Basic and Digest
authentication.

If you can use GPL/GMGPL code, look how AWS does it
and take its client side code. AWS uses GNAT.Sockets for
communication.

AWS documentation at
https://libre.adacore.com/aws/aws-gpl-2.3.0.html#Client-side
gives following example:

Although, if a website uses some custom authentication method, then
you probably need to play with HTML parsing, cookies, sessions,
and stuff.

Thanks. I am able to connect with AWS.Client.
