代码

<?phpnamespace app\shop\controller;use think\worker\Server;class Tcp extends Server
{protected $socket = 'tcp://127.0.0.1:12345';protected $option = ['name' => "order_tcp",'count' => 1,'pidFile' => 'worker.pid',
//        'daemonize' => true,];public $con;public function onConnect($connection){$connection->send('链接成功！');}public function onMessage($connection,$data){$connection->send("\n".'服务器接收成功!'."\n");$this->con = $connection;$this->dayin("测试数据");$this->dayin($data);}public function onClose($connection){}public function onError($connection,$code,$msg){echo 'error' . $code  . $msg;}public function onWorkerStart($worker){}public function dayin($msg){$this->con->send($msg);}}

然后回发现一个问题：

 [think\exception\ErrorException]Accessing static property Workerman\Worker::$pidFile as non static

正确写法

// 自定义服务类代码public function init(){parent::init();\Workerman\Worker::$pidFile = app()->getRuntimePath() . 'workerman.pid'; // `静态属性` 赋值}
