Errors when retrieving user details from Microsoft Graph using oauth2-microsoft - php

Question

I am using oauth2-microsoft to develop a 'sign in with Microsoft' tool for my app. I'm successfully authenticating and receiving a token, but then I receive an error from the sample code.
I am using the sample code below and have tried various combinations of URLs in the 'urlResourceOwnerDetails' field, including leaving it blank.
$provider = new \Stevenmaguire\OAuth2\Client\Provider\Microsoft([
'clientId' => '<redacted>',
'clientSecret' => '<redacted>',
'redirectUri' => 'http://localhost/test.php',
'urlAuthorize' => 'https://login.microsoftonline.com/common/oauth2/v2.0/authorize',
'urlAccessToken' => 'https://login.microsoftonline.com/common/oauth2/v2.0/token',
'urlResourceOwnerDetails' => 'https://graph.microsoft.com/v1.0/me/drive'
]);
$options = [
'scope' => ['wl.basic', 'wl.signin']
];
After this comes authentication and token generation.
Then this line throws errors:
$user = $provider->getResourceOwner($token);
A token is definitely being generated, as I can echo $token and see it.
The above code should create a $user object that contains details about the logged in user. However, instead it generates these errors:
If 'urlResourceOwnerDetails' is set to https://graph.microsoft.com/v1.0/me/drive I get:
League\OAuth2\Client\Provider\Exception\IdentityProviderException: Access token is empty
If 'urlResourceOwnerDetails' is set to https://outlook.office.com/api/v2.0/me I get:
UnexpectedValueException: Invalid response received from Authorization Server. Expected JSON.
And if 'urlResourceOwnerDetails' is empty I get:
GuzzleHttp\Exception\RequestException: cURL error 3: malformed (see http://curl.haxx.se/libcurl/c/libcurl-errors.html)
Any ideas, please?

It appears oauth2-microsoft does not support Microsoft Graph Auth to a full extent at the moment, refer for example this thread
Regarding the error
League\OAuth2\Client\Provider\Exception\IdentityProviderException:
Access token is empty
access token is expected to be passed as Authorization header but according to Microsoft.php provider implementation it is passed instead as query string:
public function getResourceOwnerDetailsUrl(AccessToken $token)
{
$uri = new Uri($this->urlResourceOwnerDetails);
return (string) Uri::withQueryValue($uri, 'access_token', (string) $token);
}
The way how library is designed, the following provider class could be introduced to support Microsoft Graph calls (by including access token in the Authorization header of a request)
class MicrosoftGraphProvider extends AbstractProvider
{
/**
* Get provider url to fetch user details
*
* #param AccessToken $token
*
* #return string
*/
public function getResourceOwnerDetailsUrl(AccessToken $token)
{
return 'https://graph.microsoft.com/v1.0/me';
}
protected function getAuthorizationHeaders($token = null)
{
return ['Authorization'=>'Bearer ' . $token->getToken()];
}
public function getBaseAuthorizationUrl()
{
return 'https://login.microsoftonline.com/common/oauth2/v2.0/authorize';
}
public function getBaseAccessTokenUrl(array $params)
{
return 'https://login.microsoftonline.com/common/oauth2/v2.0/token';
}
protected function getDefaultScopes()
{
return ['openid profile'];
}
protected function checkResponse(\Psr\Http\Message\ResponseInterface $response, $data)
{
// TODO: Implement checkResponse() method.
}
protected function createResourceOwner(array $response, AccessToken $token)
{
return (object)$response;
}
}
