Commit 054fe37 introduced a tiny bug, that prevents getUserContracts from generating correct URLs.

The path and query part of the URL don't get separated with a question-mark character. Replacing the dot with a comma, fixes the problem.

I'm thinking about using this library, but it's missing a LICENSE file.

What are the terms that this library can be used under?

Hi,

I'm authenticating like this

$xing = new XingWrapper();
if ( !$xing->hybridAuth->isConnectedWith('XING') ) {
    $xing->hybridAuth->authenticate('XING', ['hauth_return_to' => '/auth_xing.php']);
} else {
    $xingApi        = $xing->hybridAuth->authenticate('XING');
    var_dump($xingApi->getUserProfile());
}

However, after authenticating and calling the method getUserProfile()) I'm getting the following error

Profile request failed! XING API returned an error: 401 Unauthorized..

Do you need more information about the implementation or is this enough?

The XING API can return just the number of contacts, if you leave the limit parameter blank. But it's hardcoded to 100 and will give you all contacts including all their information. Would be nice if we have another method like getContactCount or can pass a parameter limit.
