REST Interface

Resources are accessible via RESTful URIs to allow the creation of Mash-ups:

JSON uploads should be PUT to http://server.domain/eden/module/resource.json

NB JSON must not include trailing commas in lists (just like Internet Explorer). [This is a SimpleJSON limitation]

Testing

RESTclient

Use pre-emptive authentication, when you need to login.

AJAX

Authenticate using:

function make_base_auth(user, password) {
 var tok = user + ':' + pass;
 var hash = Base64.encode(tok);
 return 'Basic ' + hash;
}

var auth = make_basic_auth('username@example.com', 'password');
var url = 'http://host.domain/eden/controller/function?vars';

// RAW
request = new XMLHttpRequest();
request.setRequestHeader('Authorization', auth);
request.open('PUT', url, true); // async=true
request.send(bodyContent);

// ExtJS
Ext.Ajax.request({
    url : url,
    method : 'GET',
    headers : { Authorization : auth }
});

// jQuery
$.ajax({
    url : url,
    method : 'GET',
    beforeSend : function(req) {
        req.setRequestHeader('Authorization', auth);
    }
});

Thanks to:

CURL

For testing/PUT using CURL follow the example

In the example - name%40example.com represents your login name@example.com and password is to be replaced by your password.

person.xml is the file name to PUT

curl -H 'content-type:application/xml' -T person.xml http://name%40example.com:password@localhost:8000/sahana/pr/person.xml&ignore_errors=False

WGET

Use the  --auth-no-challenge option in order to login to Eden.
