盘锦网站建设公司网站seo搜索引擎的原理是什么
环境：centOS7.9、php8.3、thinkphp8.0\think-swoole4.1
我用的官方think-swoole插件
第一步：根据官方文档，需要安装此扩展插件
composer require topthink/think-swoole第二步：在根目录下config文件夹下编辑swoole.php配置文件
'http'=> ['enable' => true,'host' => '0.0.0.0', // 任意ip都可以访问http服务;'port' => 8080, // 宝塔和阿里云、腾讯云的安全组需要开放此端口;'worker_num' => swoole_cpu_num(),'options' => ['daemonize' => true], // 守护进程运行],'websocket' => ['enable' => true, // 默认为false, 一定要开启'route' => false, // 最大的坑，在做测试时,一定要关闭,否则调试不出结果;'handler' => \think\swoole\websocket\Handler::class,'ping_interval' => 25000,'ping_timeout' => 60000,'room' => ['type' => 'table','table' => ['room_rows' => 8192,'room_size' => 2048,'client_rows' => 4096,'client_size' => 2048,],'redis' => ['host' => '127.0.0.1','port' => 6379,'max_active' => 3,'max_wait_time' => 5,],],'listen' => ['event' => \app\index\listener\WebsocketTest::class,//事件监听'close' => 'app\index\listener\WsClose',//关闭事件],'subscribe' => [],],第三步：我的框架是多应用模式，我创建了index应用；
// WebsocketTest.php; 路径: app\index\listener
namespace app\index\listener;
use think\Container;
use think\swoole\Websocket;class WebsocketTest
{public $websocket = null;public function __construct(Container $container){$this->websocket = $container->make(Websocket::class);}/*** 事件监听处理* @param $event*/public function handle($event){echo '接收到事件,' . $event->type . '---' . $event->data;echo '--------';var_dump($event);$func = $event->type;$this->$func($event);}/*** 测试类型* @param $event*/public function test($event){$msg = json_encode($event->data,256);$this->websocket->emit('callback', $msg);}
}第四步：websocket关闭事件
namespace app\index\listener;class WsClose
{/*** 事件监听处理** @return mixed*/public function handle($event){//echo '已经断开了';}
}第五步：前端index.html
<html>
<head>
<title>websocket</title>
</head><body>
<h1>websocket功能</h1><input id="msg" type="text"/>
<button onclick="send()">发送</button><script>var ws = new WebSocket("ws://你的ip:8080");ws.onopen = function (){console.log("连接成功");var sendObj = {};sendObj.type = 'connect';sendObj.data = 'connect success';console.log('msg',JSON.stringify(sendObj));ws.send(JSON.stringify(sendObj));}ws.onclose = function () {console.log("连接失败")}ws.onmessage = function (evt) {console.log("数据已接收",evt);}function send(){console.log('运行到这里了');var msg = document.getElementById('msg').value;var sendObj = {};sendObj.type = 'mtest';sendObj.data = msg;console.log('msg',JSON.stringify(sendObj));ws.send(JSON.stringify(sendObj));}
</script>
