[英]$facebook->getUser() always return zero
嗨,我將Facebook Connect功能集成到我的網站中。 所以我用了facebook new graph api。 我用下面的代碼..
.............
.............
$facebook = new Facebook(array(
'appId' => $fbconfig['appid'],
'secret' => $fbconfig['secret'],
));
$uid = $facebook->getUser();
var_dump($uid);
if($uid)
{
//do someting
}
else
......
但是問題在於$ uid總是為零。 為什么會這樣。 請幫忙..
嘗試這個
$user = null;
$facebook = new Facebook(array(
'appId' => $app_id,
'secret' => $app_secret,
));
$user = $facebook->getUser();
if ($user) {
echo "user";
}
else
{
echo("<script language=\"javascript\">");
echo("top.location.href = \"http://apps.facebook.com/myapp\";");
echo("</script>");
exit;
}
這是您可以使用fb帳戶登錄的代碼。
<?php
$cookie = get_facebook_cookie(FACEBOOK_APP_ID, FACEBOOK_SECRET);
if(isset($cookie))
{
$first_name = json_decode(@file_get_contents('https://graph.facebook.com/me?access_token=' .$cookie['access_token']))->first_name;
$last_name = json_decode(@file_get_contents('https://graph.facebook.com/me?access_token=' .$cookie['access_token']))->last_name;
}
?>
<script src="http://connect.facebook.net/en_US/all.js"></script>
<script>
FB.init({appId: <?php echo FACEBOOK_APP_ID;?>, status: true, cookie: true, xfbml: true});
FB.Event.subscribe('auth.logout', function(response) {});
FB.Event.subscribe('auth.sessionChange', function(response) {
if (response.session) {
FB.api('/me', function(response) {
if(response.id!='undefined')
{
window.location='Fbaccess.php?first_name='+response.first_name+'&last_name='+response.last_name+'&email='+response.email;
}
else
{
window.location='login.php';
}
});
} else {
// The user has logged out, and the cookie has been cleared
}
});
</script>
