Swoole跟thinkphp5结合开发WebSocket在线聊天通讯系统 - 八重樱 - 博客园

来源: Swoole跟thinkphp5结合开发WebSocket在线聊天通讯系统 – 八重樱 – 博客园

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:

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)

复制代码
 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'; //监听所有地址
 8     protected $port = 9501; //监听9501端口
 9     protected $serverType = 'socket';
10     protected $option = [ 
11         'worker_num'=> 4, //设置启动的Worker进程数
12         'daemonize'    => false, //守护进程化(上线改为true)
13         'backlog'    => 128, //Listen队列长度
14         'dispatch_mode' => 2, //固定模式,保证同一个连接发来的数据只会被同一个worker处理
15  
16         //心跳检测:每60秒遍历所有连接,强制关闭10分钟内没有向服务器发送任何数据的连接
17         'heartbeat_check_interval' => 60,
18         'heartbeat_idle_time' => 600
19     ];
20  
21     //建立连接时回调函数
22     public function onOpen($server,$req)
23     {
24         $fd = $req->fd;//客户端标识
25         $uid = $req->get['uid'];//客户端传递的用户id
26         $token = $req->get['token'];//客户端传递的用户登录token
27         
28         //省略token验证逻辑......
29         if (!$token) {
30             $arr = array('status'=>2,'message'=>'token已过期');
31             $server->push($fd, json_encode($arr));
32             $server->close($fd);
33             return;
34         }
35         //省略给用户绑定fd逻辑......
36         echo "用户{$uid}建立了连接,标识为{$fd}\n";
37     }
38  
39     //接收数据时回调函数
40     public function onMessage($server,$frame)
41     {
42         $fd = $frame->fd;
43         $message = $frame->data;
44  
45         //省略通过fd查询用户uid逻辑......
46         $uid = 666;
47         $data['uid'] = $uid;
48         $data['message'] = '用户'.$uid.'发送了:'.$message;
49         $data['post_time'] = date("m/d H:i",time());
50         $arr = array('status'=>1,'message'=>'success','data'=>$data);
51  
52         //仅推送给当前连接用户
53         //$server->push($fd, json_encode($arr));
54         
55         //推送给全部连接用户
56         foreach($server->connections as $fd) {
57             $server->push($fd, json_encode($arr));
58         } 
59     }
60  
61     //连接关闭时回调函数
62     public function onClose($server,$fd)
63     {
64         echo "标识{$fd}关闭了连接\n";
65     }
66 }

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
