Linux下源码包安装Swoole及基本使用操作图文详解(3)
启动服务:
php http_server.php
(如果9501端口已经被占用查看进程PID,杀死进程:)
lsof -i:9501
kill 9013
浏览器访问主机地址:端口号,得到程序预期结果即测试成功:
【创建WebSocket服务器】
创建ws_server.php:
<?php //创建websocket服务器对象,监听0.0.0.0:9501端口 $ws = new swoole_websocket_server("0.0.0.0", 9501); //配置静态文件根目录(可选) $ws ->set([ 'document_root' => '/www/wwwroot/lwsblog', 'enable_static_handler' => true, ]); //监听WebSocket连接打开事件 $ws->on('open', function ($ws, $request) { var_dump($request->fd, $request->get, $request->server); $ws->push($request->fd, "hello, welcome\n"); }); //监听WebSocket消息事件 $ws->on('message', function ($ws, $frame) { echo "Message: {$frame->data}\n"; $ws->push($frame->fd, "server: {$frame->data}"); }); //监听WebSocket连接关闭事件 $ws->on('close', function ($ws, $fd) { echo "client-{$fd} is closed\n"; }); $ws->start();
运行程序:(这里还是要确认监听的端口没有被占用,如果被占用查看进程PID,杀死进程)
php ws_server.php
前端页面js监听:(127.0.0.1改成你的主机地址)
