通过JS的websocket直接向消息服务器发送消息：

 //自动检查当前页面时候可以观看

    function authCheck($parm,$flag,$isRepeal) {
        if($isRepeal == false){
            closeVideo();
            return false;
        }
        var returnCode; // 存放同步过来的数据
        var $openId = "{{openId}}";
        var $liveId = "{{live.id}}";
        console.warn($openId);
        var url = "/redis/authcheck";
        var data =http://www.mamicode.com/ {
            ‘openId‘: $openId,
            ‘liveId‘:$liveId
        };
        var $userId;
        $.ajax({
            ‘type‘: ‘POST‘,
            ‘url‘: url,
            ‘data‘: data,
            ‘dataType‘: ‘json‘,
            async: false,   //true 异步，false 同步
            success: function (response) {
                console.warn(‘这是第一次执行‘ + response);
                if (response.errcode == 200) {
                    returnCode = response.errcode;
                    if ($flag == false) {
                        //initPost($parm, $userId);
                        var data =http://www.mamicode.com/ {
                            user_id:response.user_id,
                            openId:response.openId,

                    console.log(‘恭喜你第一次执行时可以看直播视频了‘);

                        ch.data("src", "");

                        var state = ch.data("state");
                        if (state != 3) {

            }

        });
    }
    //    setInterval(‘authCheck()‘,10000);

 

 

【1】通过WEB服务端代码：绑定clientId和Uid

  //将 client_id 与 uid 绑定
    public function bindUserAction()
    {
        header("Access-Control-Allow-Origin:*");
        header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept");
        Gateway::$registerAddress = ‘120.26.220.223:1238‘;
        $userId = $this->request->getPost(‘userId‘);
        $clientData = json_decode($this->request->getPost(‘clientData‘), true);
        $clientId = Gateway::bindUid($clientData[‘clientId‘], $userId);
        if($clientId == true){
            $result = array("errcode" => 200, "errmsg" => "bind userId success", "status" => "{$clientId}");
            return $this->toJson($result);
        }
        $result = array("errcode" => 500, "errmsg" => "bind userId fail", "status" => "{$clientId}");
        return $this->toJson($result);
    }

【2】通过消息服务端代码：绑定clientId 和Uid(携带参数验证的)

/**
 * 主逻辑
 * 主要是处理 onConnect onMessage onClose 三个方法
 * onConnect 和 onClose 如果不需要可以不用实现并删除
 */
class Events
{
    /**
     * 当客户端连接时触发
     * 如果业务不需此回调可以删除onConnect
     *
     * @param int $client_id 连接id
     */
    public static function onConnect($client_id)
    {
        // 向当前client_id发送数据
        $arr = array(‘status‘ => ‘Connection Success‘, ‘clientId‘ => $client_id);
        Gateway::sendToClient($client_id, json_encode($arr));
    }

    /**
     * 当客户端发来消息时触发
     * @param int $client_id 连接id
     * @param mixed $message 具体消息
     */
    public static function onMessage($client_id, $message)
    {
        $msgDate = json_decode($message, true);
        // 检测签名
        if (!isset($msgDate[‘sign‘])) {
            Gateway::sendToAll("$client_id:Signature cannot be empty");
            return false;
        }
        //获取本地token签名
        $signToken = self::checkSign($msgDate[‘user_id‘], $msgDate[‘openId‘]);
        //token签名验证通过则绑定uid
        if ($signToken != $msgDate[‘sign‘]) {
            Gateway::sendToAll("$client_id:Signature verification failed or expired");
            return false;
        }
        GateWay::bindUid($client_id, $msgDate[‘user_id‘]);
        Gateway::sendToAll("$client_id:$message");
    }

    /**
     * 当用户断开连接时触发
     * @param int $client_id 连接id
     */
    public static function onClose($client_id)
    {
        // 向所有人发送
        //GateWay::sendToAll("$client_id logout");
    }

    // 服务端签名
    public static function checkSign($uid, $openId)
    {
        $key = ‘http://ford4s.amailive.com/‘;
        $sign = md5($key . $uid . $openId);
        return $sign;
    }
}
