xmlhttprequest + json + pylons

Hi




JSONRequest = {
    post: function( url, data, callback, timeout ) {
        xhr = new XMLHttpRequest();
        xhr.open("POST", url, true);
        xhr.setRequestHeader( "Content-Type",
"application/x-www-form-
urlencoded" );
        if (callback) {
            xhr.onreadystatechange = function() {
                if( xhr.readyState==4 ) {
                    //alert( xhr.responseText );
                    callback( xhr.responseText );
                }
            }
        }
        if ( data ) {
            xhr.send( data );
        } else {
            xhr.send( null );
        }
    },
    get: function(url, callback) {
        alert( 'in JSONRequest.get();' );
    }
};



using above code(js) I send the
data(login={username:"python",password:"pylon
s") to pylons.



... pylons controller...

        print request.params.keys()
        print request.params.items()
        print request.params.values()


I am getting flowing output...


['login']
[('login', u'{username:"python", password:"
[u'{username:"python",
password:"pylons"}']


How can I get the username & password value ?




Thanks

Madhu Alagu

Madhu,   It looks like the data being sent via xhr is in an
improper
format.  According to the javascript you provided, data
should be a
urlencoded string.  If you send the string
'username=python&password=pylons' as data, you should be
able to
access the value of username via request.params['username'],
and the
value of password via request.params['password']
