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:
代码语言:javascript复制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)
代码语言:javascript复制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:
代码语言:javascript复制php --ri swoole
Websocket服务器中开启SSL隧道,并配置证书路径:
ws_server.php:
代码语言:javascript复制<?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 openn";
});
//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 closedn";
});
$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):
代码语言:javascript复制<!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:
代码语言:javascript复制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:
