  7. $worker->onWorkerStart = function() {
  8.     global   $dns;
  9.     $loop    = Worker::getEventLoop();
  10.     $factory = new React\Dns\Resolver\Factory();
  11.     $dns     = $factory->create('8.8.8.8', $loop);
  12. };
  14. $worker->onMessage = function($connection, $host) {
  15.     global $dns;
  16.     $dns->resolve($host)->then(function($ip) use($host, $connection) {
  17.         $connection->send("$host: $ip");
  18.     },function($e) use($host, $connection){
  19.         $connection->send("$host: {$e->getMessage()}");

  21. };
  23. Worker::runAll();

注意：

1、所有的异步编码必须在onXXX回调中编写

2、异步客户端需要的$loop变量请使用Worker::getEventLoop();返回值
