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 ";
}

evel.cancelbubble = true;
evel.preventdefault();
evel.stoppropagation();
var contents = that.val().trim();
if(contents == null || contents == ""){
layer.msg('内容为空',{shade:0.1,icon:2,time:600});
return false;
}else{
ws.send(contents);
that.val("");
}
}
});
}else{
layer.alert("您的浏览器不支持 websocket!");
}
});
</script> 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。
