在用戶牆上發布時需要幫助

Question

下面需要幫助的是我的應用程序的index.php代碼，我想在用戶使用OFFLINE_ACCESS和publish_stram授權我的應用程序后在用戶牆上發布

<?php 

 $app_id = "XXXXXXXXXX";

 $app_secret = "XXXXXXX";

 $canvas_page = "http://apps.facebook.com/esccounsel/";

 $auth_url = "http://www.facebook.com/dialog/oauth?client_id=" 
        . $app_id . "&redirect_uri=" . urlencode($canvas_page) . ("&scope=read_stream publish_stream offline_access");

 $signed_request = $_REQUEST["signed_request"];

 list($encoded_sig, $payload) = explode('.', $signed_request, 2); 

 $data = json_decode(base64_decode(strtr($payload, '-_', '+/')), true);

 if (empty($data["user_id"])) {
        echo("<script> top.location.href='" . $auth_url . "'</script>");
 } else {
        echo ("Welcome User: " . $data["user_id"]);
 } 

?>

我想直接張貼在用戶牆上，請回答

Answer 1

1. 下載Facebook PHP-SDK
2. 無需offline_access權限

3. 熟悉PHP-SDK，並使用示例頁面中的代碼作為索引，例如：

    <?php require '../src/facebook.php'; $facebook = new Facebook(array( 'appId' => 'XXXXXXX', 'secret' => 'XXXXXXXX', 'cookie' => true, )); $session = $facebook->getSession(); $loginUrl = $facebook->getLoginUrl(array( "req_perms" => "publish_stream" )); $me = null; if ($session) { try { $uid = $facebook->getUser(); $me = $facebook->api('/me'); echo "Welcome User: " . $me['name'] . "<br />"; $post_id = $facebook->api("/$uid/feed", "post", array("message"=>"Hello World!")); if(isset($post_id)) echo "A new post to your wall has been posted with id: $post_id"; } catch (FacebookApiException $e) { error_log($e); } } else { echo("<script> top.location.href='" . $loginUrl . "'</script>"); } ?>
