To use Swoole in ThinkPHP, you need to install the think Swoole composer package, provided that the system has installed the Swoole PECL extension*
To install think swoole, execute the composer command in the project root directory of tp5:
composer require topthink/think-swoole
If you don't say much, go straight to the code:
New WebSocket.php controller
(to confirm that the server is allowed to listen to the port, you need to add security group rules in pagoda environment.)
1 <?php 2 3 namespace app\home\controller; 4 use think\swoole\Server; 5 class WebSocket extends Server 6 { 7 protected $host = '0.0.0.0'; //Listen to all addresses 8 protected $port = 9501; //Listen to port 9501 9 protected $serverType = 'socket'; 10 protected $option = [ 11 'worker_num'=> 4, //Set up started Worker Process number 12 'daemonize' => false, //Daemonization (online changed to true) 13 'backlog' => 128, //Listen queue length 14 'dispatch_mode' => 2, //Fixed mode to ensure that data sent from the same connection will only be sent to the same worker Handle 15 16 //Heartbeat detection: traverse all connections every 60 seconds, and forcibly close the connection without sending any data to the server within 10 minutes 17 'heartbeat_check_interval' => 60, 18 'heartbeat_idle_time' => 600 19 ]; 20 21 //Callback function when establishing connection 22 public function onOpen($server,$req) 23 { 24 $fd = $req->fd;//Client identity 25 $uid = $req->get['uid'];//Users delivered by the client id 26 $token = $req->get['token'];//User login delivered by client token 27 28 //Omit token validation logic 29 if (!$token) { 30 $arr = array('status'=>2,'message'=>'token Expired'); 31 $server->push($fd, json_encode($arr)); 32 $server->close($fd); 33 return; 34 } 35 //Omit binding to user fd logic...... 36 echo "user{$uid}Connection established,Identified as{$fd}\n"; 37 } 38 39 //Callback function when receiving data 40 public function onMessage($server,$frame) 41 { 42 $fd = $frame->fd; 43 $message = $frame->data; 44 45 //Omission through fd Query users uid logic...... 46 $uid = 666; 47 $data['uid'] = $uid; 48 $data['message'] = 'user'.$uid.'Sent:'.$message; 49 $data['post_time'] = date("m/d H:i",time()); 50 $arr = array('status'=>1,'message'=>'success','data'=>$data); 51 52 //Push to current connected users only 53 //$server->push($fd, json_encode($arr)); 54 55 //Push to all connected users 56 foreach($server->connections as $fd) { 57 $server->push($fd, json_encode($arr)); 58 } 59 } 60 61 //Callback function when connection is closed 62 public function onClose($server,$fd) 63 { 64 echo "Identification{$fd}Connection closed\n"; 65 } 66 }

Move the server to the project root directory to start the service:
php public/index.php Websocket/start
The path here is because I bound the home module as the default module. The default situation of tp5 is: php public/index.php index/Websocket/start)
Open successfully. Check whether the port has been monitored:
lsof -i:9501
