How to get permission?
I have create a simple facebook application. Now I want to get permission for read_stream.
I have read a lot of documentation but I don't understand.
Could you tell me how to get this permission with PHP or javascript ?
Edit:
I have used this source code ( you can se it working here ) but doesn't work because I get only basic permission:
<?php
require_once('facebook.php');
// Create our Application instance (replace this with your appId and secret).
$facebook = new Facebook(array(
'appId' => 'xxx',
'secret' => 'xxx',
'cookie' => true,
));
$session = $facebook->getSession();
$me = null;
// Session based API call.
if ($session) {
try {
$uid = $facebook->getUser();
$me = $facebook->api('/me');
} catch (FacebookApiException $e) {
error_log($e);
}
}
// login or logout url will be needed depending on current user state.
if (!$me) {
$loginUrl = $facebook->getLoginUrl();
} else {
// $fbme is valid i.e. user can access our app
$logoutUrl = $facebook->getLogoutUrl();
}
// This call will always work since we are fetching public data.
?>

// server-side to verify
$permissions = $facebook->api("/me/permissions");
if( array_key_exists('publish_stream', $permissions['data'][0]) ) {
$result = $facebook->api($feed_dir, 'post', $msg_body);
}
// result is id of post
In javascript API you can request permissions during login using FB.login(). More about it here (with examples)
In PHP you can request extended permission during authentication process. More about it here (see "Requesting Extended Permissions")
Javascript approach is much easier imo.
UPDATE
Ok there is the third way of getting permissions using fb:login-button fbml tag:
<fb:login-button perms="read_stream,offline_access"></fb:login-button>
加载中,请稍侯......
