首先要申请SSL证书,必须为pem格式。
如图为宝塔环境所申请Let's Encrypt免费证书的所在位置:
Linux安装openssl支持:
yum install -y openssl
移到Swoole安装包目录,重新编译安装,并加入openssl支持:(相关文章:Linux下源码包安装Swoole及基本使用)
phpize ./configure --enable-openssl --with-php-config=/www/server/php/72/bin/php-config make clean make && make install
查看Swoole已经开启openssl支持:
php --ri swoole
Websocket服务器中开启SSL隧道,并配置证书路径:
ws_server.php:
<?php //创建websocket服务器对象,监听0.0.0.0:9501端口,开启SSL隧道 $ws = new swoole_websocket_server("0.0.0.0", 9501, SWOOLE_PROCESS, SWOOLE_SOCK_TCP | SWOOLE_SSL); //配置参数 $ws ->set([ 'daemonize' => false, //守护进程化。 //配置SSL证书和密钥路径 'ssl_cert_file' => "/etc/letsencrypt/live/oyhdo.com/fullchain.pem", 'ssl_key_file' => "/etc/letsencrypt/live/oyhdo.com/privkey.pem" ]); //监听WebSocket连接打开事件 $ws->on('open', function ($ws, $request) { echo "client-{$request->fd} is open\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();
页面js中即可使用wss连接WebSocket服务器(使用与证书对应的域名):
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>WebSocket</title> </head> <body> </body> <script type="text/javascript"> var websocket = new WebSocket('wss://www.oyhdo.com:9501'); websocket.onopen = function (evt) { onOpen(evt) }; websocket.onclose = function (evt) { onClose(evt) }; websocket.onmessage = function (evt) { onMessage(evt) }; websocket.onerror = function (evt) { onError(evt) }; function onOpen(evt) { console.log("Connected to WebSocket server."); websocket.send('666'); } function onClose(evt) { console.log("Disconnected"); } function onMessage(evt) { console.log('Retrieved data from server: ' + evt.data); } function onError(evt) { console.log('Error occured: ' + evt.data); } </script> </html>
启动WebSocket服务:
php ws_server.php
浏览器访问结果:(注意必须为https访问)
服务器监听结果:
