我在网站登录facebook后重定向页面时遇到问题。
1.点击网站上的facebook登录按钮,重定向到facebook登录页面
2.用户获得身份验证,但不会重定向到headrer('');
中给出的下一页
3.如果我刷新同一页面,则会重定向到指定位置,网址看起来像=“> http://192.1.1.1/mysite/welcome.php/# =
4.它适用于google.com但不适用于本地网址和Google网址的网址看起来像incorrect google url
我的代码
if(isset($_GET['fb']))
{
$token_url = "https://graph.facebook.com/oauth/access_token?"."client_id=".$config['App_ID']."&redirect_uri=".urlencode($config['callback_url'])."&client_secret=".$config['App_Secret']."&code=".$_GET['code'];
$response = file_get_contents($token_url);
$params = null;
parse_str($response, $params);
$graph_url = "https://graph.facebook.com/me?access_token=".$params['access_token'];
$user = json_decode(file_get_contents($graph_url)); //user data from facebook
$email = $user->{'email'}; //i am getting email id from json data
//search out for entry available for email in database
$val_user = "SELECT email FROM tbl_facebook WHERE email ='".$email."'";
$res_val_user = $con->query($val_user);
$count = mysqli_num_rows($res_val_user);
// if not then insert data to database
if($count==0)
{
$ins_fb = "INSERT INTO tbl_facebook set email='".$email."'";
$res_fb = mysqli_query($con,$ins_fb);
if($res_fb)
{
//echo "facebook data saved"; exit; //working for this
//header('Location:https://www.google.co.in/'); //working for this also
header('Location:http://192.1.1.1/mysite/welcome.php');
}
else
{
echo "facebook data is not saved";
}
}
else // if yes then redirect to welcome page
{
//echo "login successfully"; exit; // working for this also
header('Location:http://192.1.1.1/mysite/welcome.php'); // getting problem to redirect
//header('Location:https://www.google.co.in/');
}
}
<?php
// code for facebook login
require 'lib/facebook/src/config.php';
require 'lib/facebook/src/facebook.php';
// Create our Application instance (replace this with your appId and secret).
$facebook = new Facebook(array(
'appId' => $config['App_ID'],
'secret' => $config['App_Secret'],
'cookie' => true
));
?>
<a class="btn-facebook" href="https://www.facebook.com/dialog/oauth?client_id=<?php echo $config['App_ID']?>&redirect_uri=<?php echo $config['callback_url']?>&scope=email,user_likes,publish_stream">
<i class="icon-facebook icon-large"></i>
Signin with Facebook
</a>

标头重定向问题通常是在PHP关闭标记之后或开始标记之前有空格,在标题()之前输出等。
为避免这种情况,我们需要确保
此外,即使header()不起作用,也可以将exit()添加为
header('Location:http://192.1.1.1/mysite/welcome.php');
exit();
最后你可以使用JS作为
echo '<script>window.location = "'.$url.'";</script>';
exit;
希望这会有所帮助:)

只使用本地路径网址不要使用完整网址
header("Location: welcome.php");
