Swoole 跟 thinkphp5 结合开发 WebSocket 在线聊天通讯系统
ThinkPHP 使用 Swoole 需要安装 think-swoole Composer 包,前提系统已经安装
好了 Swoole PECL 拓展
tp5 的项目根目录下执行 composer 命令安装 think-swoole:
1 composer require topthink/think-swoole
话不多说,直接上代码:
新建 WebSocket.php 控制器:
(监听端口要确认服务器放行,宝塔环境还需要添加安全组规则)
<?php namespace app\home\controller;use think\swoole\Server;class WebSocket e xtends Server{ protected $host = '0.0.0.0'; //监听所有地址protected $port = 9501; //监听 9501 端口 protected $serverType = 'socket'; protected $option = [ 'worker_num'=> 4, //设置启动的 Worker 进程数 'daemonize' => false, //守护进程化(上线改为 true) 'backlog' => 128, //Listen 队列长度 'dispatch_mode' => 2, //固定模式,保证同一个连接发来的数据只会被同一个 worker 处理 //心跳检测:每 60 秒遍历所有连接,强制关闭 10 分钟内没有向服务器发送任何 数据的连接 'heartbeat_check_interval' => 60, 'heartbeat_idle_time' => 600 ]; //建立连接时回调函数 public function onOpen($server,$req) { $fd = $req->fd;//客户端标识 $uid = $req->get['uid'];//客户端传递的用户 id $token = $req->get['token'];//客户端传递的用户登录 token //省略 token 验证逻辑......if (!$token) { $arr = array('status'=>2,'message'=>'token 已过期'); $server->push($fd, json_encode($arr)); $server->close($fd); return; } //省略给用户绑定 fd 逻辑...... echo "用户{$uid}建立了连接,标识为{$fd}\n"; } //接收数据时回调函数 public function onMessage($server,$frame) { $fd = $frame->fd; $message = $frame->data; //省略通过 fd 查询用户 uid 逻辑...... $uid = 666; $data['uid'] = $uid; $data['message'] = '用户'.$uid.'发送了:'.$message; $data['post_time'] = date("m/d H:i",time()); $arr = array('status'=>1,'message'=>'success','data'=>$data);//仅推送给当前连接用户 //$server->push($fd, json_encode($arr)); //推送给全部连接用户 foreach($server->connections as $fd) { $server->push($fd, json_encode($arr)); } } //连接关闭时回调函数 public function onClose($server,$fd) { echo "标识{$fd}关闭了连接\n"; } }

(省略控制器判断登录状态、分配数据逻辑......)

服务器移到项目根目录开启服务:
php public/index.php Websocket/start
这里的路径,是因为我绑定了 home 模块为默认模块,tp5 默认情况是:php
public/index.php index/Websocket/start)
开启成功,查看端口已经被监听:
lsof -i:9501
