关于从授权我的应用程序并使用它的一些Facebook用户那里获取数据(通常是顺便说一句),我有一个奇怪但非常严重的问题.
到目前为止,大约有3000个用户使用过该应用程序,但只有600个用户在用户表中显示.怎么可能呢?我无法找到新旧用户之间的联系 – 对于一些用户而言,它可以完美地工作,对于其他用户而言根本不起作用.
这是完整的,但出于安全考虑,审查代码:
<?php
require 'facebook.php';
include 'config.php';
session_start();
$app_id = 'id';
$app_secret = 'secret';
$app_namespace = 'namespace';
$app_url = 'https://apps.facebook.com/' . $app_namespace . '/';
$scope = 'email,publish_actions';
//初始化Facebook SDK
$facebook = new Facebook(array(
'appId' => $app_id,
'secret' => $app_secret,
'cookie' => true
));
//获取当前用户
$user = $facebook->getUser();
//如果用户尚未安装应用程序,请将其重定向到Auth Dialog
if (!$user) {
$loginUrl = $facebook->getLoginUrl(array(
'scope' => $scope,
'redirect_uri' => $app_url,
));
print('<script> top.location.href=\'' . $loginUrl . '\'</script>');
}
else if ($user) {
try {
//继续了解我们已经有一个已经过身份验证的登录用户.
$fbuid = $facebook->getUser();
$user_profile = $facebook->api('/me');
} catch (FacebookApiException $e) {
error_log($e);
$user = null;
}
}
else{
header('Location: index.php');
}
$queryUserExists = mysql_query("SELECT * FROM users WHERE oauth_provider = 'facebook'AND oauth_uid = " . $user_profile['id']);
$num=mysql_numrows($queryUserExists);
//如果没有,请将其添加到数据库中
if ($num == 0) {
$query = mysql_query("INSERT INTO users (oauth_uid, oauth_provider, username, first_name, last_name, email, pic_square ,login_date , dailytokens)
VALUES ({$user_profile['id']}, 'facebook', '{$user_profile['name']}', '{$user_profile['first_name']}','{$user_profile['last_name']}','{$user_profile['email']}', '".$photolink."',CURDATE(),1)");
$query = mysql_query("SELECT * FROM users WHERE oauth_uid = " . mysql_insert_id());
$result = mysql_fetch_array($query);
}
else
{
$DateLastLogin=mysql_result($queryUserExists,0,"login_date");
$myDate = date('Y-m-d');
$CompLastDate = strtotime($DateLastLogin);
$CompMyDate = strtotime($myDate);
if($CompLastDate < $CompMyDate){
$updateDailyToken = "Update users set login_date=CURDATE(), dailytokens = dailytokens + 1 where oauth_uid =" . $user_profile['id'];
$updateToken= mysql_query($updateDailyToken) or die(mysql_error());
}
}
$query = mysql_query("SELECT * FROM users WHERE oauth_provider = 'facebook' AND oauth_uid = " . $user_profile['id']);
$_SESSION['userid']=$user_profile['id'];
//根据当前用户状态,将需要登录或注销URL.
if ($user) {
$paramsout = array('next'=>'http://facebook.com');
$logoutUrl = $facebook->getLogoutUrl($paramsout);
}
?>
最佳答案 这是你的问题
$query = mysql_query("INSERT INTO users (oauth_uid, oauth_provider, username, first_name, last_name, email, pic_square ,login_date , dailytokens)
VALUES ({$user_profile['id']}, 'facebook', '{$user_profile['name']}', '{$user_profile['first_name']}','{$user_profile['last_name']}','{$user_profile['email']}', '".$photolink."',CURDATE(),1)");
它应该是
$query = mysql_query("INSERT INTO users (oauth_uid, oauth_provider, username, first_name, last_name, email, pic_square ,login_date , dailytokens)
VALUES ('{$user_profile['id']}', 'facebook', '{$user_profile['name']}', '{$user_profile['first_name']}','{$user_profile['last_name']}','{$user_profile['email']}', '{$photolink}',CURDATE(),1)");
