Codeigniter和Facebook PHP SDK - 錯誤發布到用戶牆

Question

我正在使用FB PHP SDK將消息發布到用戶的牆上。 一旦用戶通過FB進行身份驗證，我就允許他們使用此幫助程序函數發布消息

function post_facebook($fb) {

    $CI =& get_instance();

    $CI->load->library('facebook');

    $config = array(
        'appId'  => '123123123123',
        'secret' => '567567567567'
    );

    $facebook = new Facebook($config);
    $user_id  = $facebook->getUser();

    if ($user_id) {

        $facebook->api('/me/feed', 'POST', array(
                                              'message' => $fb['post_text'],
                                           )
                   );
     }
}

這實際上是將帖子發送給FB，它顯示在牆上。

但是在Firebug中我可以看到這個錯誤

<h4>A PHP Error was encountered</h4>

<p>Severity: Warning</p>
<p>Message:  Missing argument 1 for Facebook::__construct(), called in /var/www/vhosts/example.com/httpdocs/system/core/Loader.php on line 1099 and defined</p>
<p>Filename: libraries/Facebook.php</p>
<p>Line Number: 36</p>

</div><div style="border:1px solid #990000;padding-left:20px;margin:0 0 10px 0;">

<h4>A PHP Error was encountered</h4>

<p>Severity: Notice</p>
<p>Message:  Undefined variable: config</p>
<p>Filename: libraries/Facebook.php</p>
<p>Line Number: 40</p>

</div>

知道我做錯了什么嗎？

Answer 1

您看到的錯誤來自對$this->load->library('facebook')的調用，您應該將$ config數組作為參數傳遞給它並從CI對象訪問庫，如下所示：

$config = array(
    'appId'  => '123123123123',
    'secret' => '567567567567'
);
$CI->load->library('facebook', $config);

$user_id  = $CI->facebook->getUser();
