[one-ecosystem] Which cloud interface to choose

[Hector Sanjuan]

Hi John,

If you look at current implementation of occi-server.rb will see that
every operation is authenticated using html basic authentication (this is
done at the "before do..end" chunk). That means, a special header inserted
in every request.

Included client utils such is occi-storage set this header everytime, when
they do this:

                 req.basic_auth @occiauth[0], @occiauth[1]

For your application you need to either do the same, and set basic auth
headers everytime you request something from the server, or slightly
modify the server to implement a login method "login" and enable
"sessions", very similar to what is done in sunstone-server.rb.

An example of how this headers are set up using jQuery ajax method for
sunstone:

                 $.ajax({
                     url: "ui/login",
                     type: "POST",
                     data: {remember: remember},
                     beforeSend : function(req) {
                         req.setRequestHeader( "Authorization",
                                             "Basic " + btoa(username + ":"  
+
password)
                                             )
                     },
                     success: ...
                     error: ...
                 });

I think in 3.0 the "password" should be SHA1-hashed before sending it (not
100% sure now).

I dont know how you plan your application, but note that Sunstone is very
flexible and that using Groups + ACLs + Custom plugins may already cover
your requirements and save you some time. Some useful documentation is
here http://opennebula.org/documentation:rel3.0:sunstone#tuning_extending

Good luck,

Hector
