移动用户尝试登录我的网站时出现问题，而登录在桌面浏览器上运行正常。我已将facebook apps dev部分中的Mobile URL设置为与浏览器相同。
在第一次加载时，它无法获得'$ fb_user = $ facebook-＆gt; getUser（）;' （它返回0）然后重新加载，因为它没有在第一次登录，然后我得到fb信息（'CSRF状态标记与提供的不匹配'。）。然后我有另一个重新加载，它没有再次获取fb_user，因此然后陷入此登录/无登录循环。使用普通浏览器，它第一次获取$ fb_user，然后后续代码与重定向一起使用。
fb代码看起来像这样：
function fb_fresh() {
global $user, $loginUrl;
//Add the FB library code. This is version 3.1.1. have updated this to the latest version as of 10 Sept 2012
$path_fb = "sites/all/modules/custom/fb/facebook.php";
require_once $path_fb; //make sure curl is installed to work
// Create our Application instance. (not revealed for obvious reasons)
$facebook = new Facebook(array('appId' => '###','secret' => '###','cookie' => true,));
// Get User array
$fb_user = $facebook->getUser();
//printing error logs to see where things go wrong..
error_log("function fb(). fbuser = " . $fb_user . ". Drupal user->uid = " . $user->uid, 0);
// $fb_user = 0 when no logged-in user. https://developers.facebook.com/docs/reference/php/facebook-getUser/
if ($fb_user != "0") {
$logoutUrl = $facebook->getLogoutUrl();
$sessionURL = "<a href='" . $logoutUrl . "' target='_top'>Logout</a>";
} else {
//Get the permissions + once the user has accepted permissions send them to a page that redirects them back to the Facebook app, which then automatically goes to the mobile version if necessary
$params_login = array(
'scope' => 'email, user_location, friends_location, user_status, friends_status, user_checkins, user_work_history, user_education_history, user_birthday, user_relationships, friends_checkins',
'redirect_uri' => 'https://' . $_SERVER['HTTP_HOST'] . '/fb_redirect',
);
$loginUrl = $facebook->getLoginUrl($params_login);
$sessionURL = "<a href='" . $loginUrl . "' target='_top'>Login</a>";
//this triggers fb dialog box when app request is sent and if user goes to certain page without logging in. works fine.
if ($fb_user == 0 && arg(0) == 'page') {
print "<script type='text/javascript'>top.location.href = '$loginUrl';</script>";
error_log("function fb(). JS redirect to LOGIN URL triggered..", 0); //loginUrl = " . $loginUrl
//clear session variables to start over
unset($_SESSION);
error_log("function fb(). clear session ", 0);
}
error_log("function fb(). NOT logged in.", 0); //loginUrl = " . $loginUrl
}
if ($fb_user) {
try {
$access_token = $facebook->getAccessToken();
$facebook->setAccessToken($access_token);
//Proceed knowing you have a logged in user who's authenticated.
//Save facebook data as session variables
$_SESSION['user_profile'] = $facebook->api('/me');
$_SESSION['user_relationships'] = $facebook->api('/me/family');
$_SESSION['user_friends'] = $facebook->api('/me/friends');
$_SESSION['user_checkins'] = $facebook->api('/me/statuses');
error_log("function fb(). fbuser = " . $fb_user . ". facebook user_profile->id = " . $_SESSION["user_profile"]["id"], 0);
return array($_SESSION['user_profile'], $_SESSION['user_relationships'], $_SESSION['user_checkins'], $_SESSION['user_friends'], 1);
} catch (FacebookApiException $e) {
error_log("function fb(). " . $e);
}
}
return array(false, false, false, false, false);
}
