Я пытаюсь получить идентификатор пользователя Facebook, используя php sdk, как это
$fb = new Facebook\Facebook([
'app_id' => '11111111111',
'app_secret' => '1111222211111112222',
'default_graph_version' => 'v2.4',
]);
$helper = $fb->getRedirectLoginHelper();
$permissions = ['public_profile','email']; // Optional permissions
$loginUrl = $helper->getLoginUrl('http://MyWebSite', $permissions);
echo '<a href="' . $loginUrl . '">Log in with Facebook!</a>';
try {
$accessToken = $helper->getAccessToken();
var_dump($accessToken);
} catch (Facebook\Exceptions\FacebookResponseException $e) {
// When Graph returns an error
echo 'Graph returned an error: ' . $e->getMessage();
exit;
} catch (Facebook\Exceptions\FacebookSDKException $e) {
// When validation fails or other local issues
echo 'Facebook SDK returned an error: ' . $e->getMessage();
exit;
}
if (!isset($accessToken)) {
if ($helper->getError()) {
header('HTTP/1.0 401 Unauthorized');
echo "Error: " . $helper->getError() . "\n";
echo "Error Code: " . $helper->getErrorCode() . "\n";
echo "Error Reason: " . $helper->getErrorReason() . "\n";
echo "Error Description: " . $helper->getErrorDescription() . "\n";
} else {
header('HTTP/1.0 400 Bad Request');
echo 'Bad request';
}
exit;
}
// Logged in
echo '<h3>Access Token</h3>';
var_dump($accessToken->getValue());
// The OAuth 2.0 client handler helps us manage access tokens
$oAuth2Client = $fb->getOAuth2Client();
// Get the access token metadata from /debug_token
$tokenMetadata = $oAuth2Client->debugToken($accessToken);
echo '<h3>Metadata</h3>';
var_dump($tokenMetadata);
// Validation (these will throw FacebookSDKException when they fail)
$tokenMetadata->validateAppId($config['11111111111']);
// If you know the user ID this access token belongs to, you can validate it here
//$tokenMetadata->validateUserId('123');
$tokenMetadata->validateExpiration();
if (!$accessToken->isLongLived()) {
// Exchanges a short-lived access token for a long-lived one
try {
$accessToken = $oAuth2Client->getLongLivedAccessToken($accessToken);
} catch (Facebook\Exceptions\FacebookSDKException $e) {
echo "<p>Error getting long-lived access token: " . $helper->getMessage() . "</p>\n\n";
exit;
}
echo '<h3>Long-lived</h3>';
var_dump($accessToken->getValue());
}
$_SESSION['fb_access_token'] = (string)$accessToken;
но он дает мне эту ошибку:
Facebook SDK returned an error:
Cross-site request forgery validation failed.
The "state" param from the URL and session do not match.
пожалуйста, любая помощь, я новичок в php и Facebook sdk благодарим за любую помощь заранее.
