Events::onWebSocketConnect

说明:

void Events::onWebSocketConnect(string $client_id, array $data);

(要求Gateway版本>=3.0.8) 如何查看Gateway版本

当客户端连接上gateway完成websocket握手时触发的回调函数。

注意：此回调只有gateway为websocket协议并且gateway没有设置onWebSocketConnect时才有效。

参数

$client_id

client_id固定为20个字符的字符串，用来全局标记一个socket连接，每个客户端连接都会被分配一个全局唯一的client_id。

$data

websocket握手时的http头数据，包含get、server等变量

返回值

无返回值，任何返回值都会被视为无效的

范例

use \GatewayWorker\Lib\Gateway;

class Events
{

    public static function onWebSocketConnect($client_id, $data)
    {
        var_export($data);
        if (!isset($data['get']['token'])) {
             Gateway::closeClient($client_id);
        }
    }
}

客户端连接代码类似:

var ws = new WebSocket('ws://127.0.0.1:7272/?token=kjxdvjkasfh');

服务端终端打印类似：

array (
  'get' => 
  array (
    'token' => 'kjxdvjkasfh',
  ),
  'server' => 
  array (
    'REQUEST_METHOD' => 'GET',
