[PHP]通过外部客户端使用JAXL在Facebook上发送消息

我正在使用JAXL3.x编写一个模块，允许我向另一个facebook用户发送消息

public function sendTo($id = null, $name = null, $user = null){
    if(!$id)
        throw new NotFoundException(__('Invalid user id'));
    if(!$name)
        throw new NotFoundException(__('Invalid name'));
    if(!$user)
        throw new NotFoundException(__('Invalid user'));
    $this->set('mess',$_POST['mess']);
    $this->set('id',$id);
    $this->set('name',$name);

    $config = new Config();
    $client = new JAXL(array(
            // (required) credentials
            'jid' => $id,
            'fb_app_key' => $config->fb_app_id,
            'fb_access_token' => $config->fb_access_token,

            // force tls (facebook require this now)
            'force_tls' => true,
            // (required) force facebook oauth
            'auth_type' => 'X-FACEBOOK-PLATFORM',

            // (optional)
            //'resource' => 'resource',

            'log_level' => JAXL_INFO
    ));

    //
    // add necessary event callbacks here
    //


    $client->add_cb('on_auth_success', function() {
        echo "got on_auth_success cb, jid ".$client->full_jid->to_string();
    });

        $client->add_cb('on_auth_failure', function($reason) {
            $client->send_end_stream();
            echo "got on_auth_failure cb with reason $reason";
        });

            $client->add_cb('on_chat_message', function($stanza) {

                // echo back incoming message stanza
                $stanza->to = $id;
                $stanza->from = $client->full_jid->to_string();
                $client->send($stanza);
            });

                $client->add_cb('on_disconnect', function() {
                    echo "got disconnected";
                });

                    //
                    // finally start configured xmpp stream
                    //
                    $client->start();
                    echo "done\n";
}

但在输入“on_auth_success”之后，我发现一个空$client错误。但正如您在代码中看到的，在$client创建之后，我尝试了通过print\r（$client）打印其内容；结果是：

这意味着$client成功连接到XMPP服务。有什么帮助吗

\\\\\\\\添加注释\\\\\\\\\

我正在使用cakephp开发web应用程序。

您缺少

global$client

没有它，

$client

变量将默认为

null
