To use with json request, you need to first create a username/password hash:
var passwordString = Lang.format("$1$:$2$", [userName, password]);
passwordHash = Base64Encoder.encode(passwordString);
Then you need to add a headers dictionary to the options dictionary of your json request:
var headers = {"Content-Type" => Comm.REQUEST_CONTENT_TYPE_URL_ENCODED};
if (passwordHash != null) {
headers.put("Authorization", Lang.format("Basic $1$", [passwordHash]));
}
var options = { :method => Comm.HTTP_REQUEST_METHOD_GET,
:headers => headers};
Comm.makeJsonRequest(url, parameters, options, callback);
Of course you'll need to handle the UnknownCharException (for diacritics and other unsupported chars).
If you find this useful and decide to use it, a pm or reply is appreciated.
