use Swoole\WebSocket\Frame;
use Swoole\Coroutine\Http\Client;
use Swoole\Coroutine\Channel;

$server = new Server("0.0.0.0", 9503);

// 存储客户端与后端 WebSocket 连接的映射
$backendConnections = [];

$server->on('open', function(Server $server, Request $request) use (&$backendConnections) {
    echo "Connection open: {$request->fd}\n";

    // 创建与后端 WebSocket 服务器的连接
    $cli = new Client('back.example.com', 9502);
   // 如果是wss
    //$cli = new Client('back.example.com', 9502,true);
    $cli->setHeaders([
        'Host' => 'back.example.com',
        'Upgrade' => 'websocket',
        'Connection' => 'Upgrade',
        'Sec-WebSocket-Key' => base64_encode(random_bytes(16)),
        'Sec-WebSocket-Version' => '13',
        'Authorization' => 'Bearer API_KEY',//可以船体key
    ]);

    if ($cli->upgrade('/')) {
        echo "Connection established with backend server\n";
        // 存储客户端与后端连接的映射
        $backendConnections[$request->fd] = $cli;

        // 启动一个协程处理后端消息
        go(function() use ($server, $request, $cli) {
            while (true) {
                $message = $cli->recv();
