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）
<?php
namespace app\home\controller;
use think\swoole\Server;
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}\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";
}
}
