thinkphp接口开发实例
ThinkPHP5.0框架结合Swoole开发实现WebSocket在线聊天案例详解本文实例讲述了thinkphp5.0框架结合swoole开发实现websocket在线聊天案例。分享给大家供大家参考,具体如下:
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(相关文章:linux下源码包安装使用swoole扩展)
在tp5的项目根目录下执行composer命令安装think-swoole:
|
composer require topthink/think-swoole |
安装成功:
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 apphomecontroller; use thinkswooleserver; class websocket extends 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} " ; } //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 " ; } } |

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 |
演示效果如下:
服务器监听如下:
用户每刷新重连一次,fd标识都会改变。
希望本文所述对大家基于thinkphp框架的php程序设计有所帮助。
