我正在学习如何为facebook创建一个应用程序。 我想要的是一个应用程序,用户授权后,收集用户的信息(名称,电子邮件,bday),将其插入数据库,并在用户的墙上自动提供。
我有这段代码,但是当我运行它时,浏览器告诉我该网页导致了太多的重定向。
我经常搜索并测试了许多不同的方法。看来这段代码以前工作过,但是facebook改变了一些东西。我已经尽力更新它而没有结果。请看一下它并指导我解决它。
由于 这是我在根文件夹中保存为index.php的代码。
<?php
session_start();
if (!empty($_SESSION)) {
header("Location: index.php");
}
mysql_connect('host', 'username', 'pass');
mysql_select_db('dbname');
# require library
require("src/facebook.php");
# Creating the facebook object
$facebook = new Facebook(array(
'appId' => 'xxxxxx',
'secret' => 'xxxxxxxx',
'cookie' => true
));
# check active session
$user = $facebook->getUser();
if (!empty($user)) {
# session active, get user id (getUser()) and user info (api->('/me'))
try {
$uid = $facebook->getUser();
$fb_access_token=$user['access_token'];
$url = $facebook->getLoginUrl(array(
'req_perms' => 'email,status_update,publish_stream,user_birthday'
));
$user = $facebook->api('/me');
$photolink = 'http://graph.facebook.com/'.$user['id'].'/picture?type=square';
$param = array(
'method' => 'users.getInfo',
'uids' => uid,
'fields' => 'pic_big'
);
$users_getinfo = $facebook->api($param);
} catch (Exception $e) {
}
if (!empty($user)) {
# active session, check if already registered the user
$query = mysql_query("SELECT * FROM users WHERE oauth_provider = 'facebook' AND oauth_uid = " . $user['id']);
$result = mysql_fetch_array($query);
# If not, add it to the database
if (empty($result)) {
$query = mysql_query("INSERT INTO users (oauth_uid, oauth_provider, username, first_name, last_name, birthday, email, pic_square) VALUES ('facebook', {$user['id']}, '{$user['name']}', '{$user['first_name']}', '{$user['last_name']}', '{$user['birthday']}', '{$user['email']}', '".$photolink."')");
$query = mysql_query("SELECT * FROM users WHERE id = " . mysql_insert_id());
$result = mysql_fetch_array($query);
}
// variables in the session
$_SESSION['id'] = $result['id'];
$_SESSION['oauth_uid'] = $result['oauth_uid'];
$_SESSION['oauth_provider'] = $result['oauth_provider'];
$_SESSION['username'] = $result['username'];

答案 0 :(得分:1)
您确实在代码中创建了一个循环。它表示如果用户有活动会话,则将其重定向到index.php。从那里他将被重定向到index.php,依此类推。
if (!empty($_SESSION)) {
header("Location: index.php");
}
我不确定你要对这个重定向做什么,但肯定会导致循环。
