facebook redirect_uri重定向到本地域，而不是停留在facebook上

Question

My facebook application will not stay on facebook after the request permissions dialog has been shown. It keeps redirecting to the redirect_uri (State the obvious), but my question is how can i get the application to run in facebook iframe?

I have tried setting the redirect_uri to https://apps.facebook.com/myApp but that is not allowed it shows an error?

Given URL is not permitted by the application configuration.: One or more of the given URLs is not allowed by the App's settings. It must match the Website URL or Canvas URL, or the domain must be a subdomain of one of the App's domains.

My current Code

<?php
require 'facebook/facebook.php';

// Get User ID
$facebook_config = array(
  'appId'  => '8**************3',
  'secret' => '5*************************d',
  'cookie'  =>  true
);

$facebook = new Facebook($facebook_config);

$user = $facebook->getUser();

$login_url = $facebook->getLoginUrl(array(
  'redirect_uri' => 'localhost';
  'scope'   =>  'user_location'
));

$logout_url = $facebook->getLogoutUrl();

if($user)
{
    $user_profile = $facebook->api('/me');
    header("Content-Type:text/plain");
    print_R($user_profile);
    die();
}
else if(!$user)
{
    echo "<script type='text/javascript'>top.location.href = '$login_url';</script>";
}
?>

Answer 1

You can remove this line: 'redirect_uri' => 'localhost';

Since, after login if nothing is mentioned in redirect_uri , it will redirect to the same page automatically.

In case you want to proceed to some other page, say success.php , you should give the redirect_uri wrt the canvas url ie the actual url of this page, not http://apps.facebook .......

Answer 2

Thank you for your answer but when 'redirect_uri' => 'localhost'; is removed it still redirects to localhost and gets stuck.

I did a quick fix that did a redirection back to facebook

$token = $_GET['code'];
if ($token) { ?>
<form action="https://apps.facebook.com/MyApp/" method="post" name='frm'>
    <input type="hidden" name="token" value="<?=$token?>">
</form>
<script language="JavaScript">
    document.frm.submit();
</script>

That redirected everything back to facebook and would work, but as you said here

In case you want to proceed to some other page, say success.php, you should give the redirect_uri wrt the canvas url ie the actual url of this page, not http://apps.facebook .......

i changed my redirect_uri from localhost to https://apps.facebook.com/MyApp/index.php and everything worked smoothly,
