测试版本
虚拟机案例地址 http://192.168.13.121/swoole_file_frontend/demo/index.html
服务器要求
1.安装并启用swoole组件 https://segmentfault.com/a/1190000008285814 安装方式大同小异
2.编辑一个启动webSocket的server.php文件
~~~
<?php
//连接本地的 Redis 服务
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);
$redis->set("fd", "[]"); //每次第一次执行都需要先清空reids里面的标识
$server = new swoole_websocket_server("0.0.0.0", 9502);
$server->on('open', function (swoole_websocket_server $server, $request) use($redis) {
echo "访客{$request->fd}进来了\n";
$server->push($request->fd, "{$request->fd}客户进来了");
$str = json_decode($redis->get("fd"), true);
if($str == "") $str = [];
if(!in_array($request->fd, $str)){
array_push($str, $request->fd);
$str = json_encode($str);
$redis->set("fd", $str);
echo "目前在线访客：";
print_r($redis->get("fd"));
}
});
$server->on('message', function (swoole_websocket_server $server, $frame) use($redis) {
echo "系统消息说：{$frame->data}\n";
$str = json_decode($redis->get("fd"), true);
foreach ($str as $key => $value) {
if($frame->fd != $value){
$server->push($value, "系统消息说:".$frame->data);
}
}
});
$server->on('close', function ($ser, $fd) use($redis) {
echo "client {$fd} closed\n";
$str = json_decode($redis->get("fd"), true);
$point = array_keys($str, $fd, true); //search key
array_splice($str, $point['0'],1); //delete array
$str = json_encode($str);
$redis->set("fd", $str);
echo "删除后在线访客：";
print_r($redis->get("fd"));
});
$server->start();

3.服务器安全测试开放9502端口，服务器内部开发端口或者直接关闭防火墙
4.启动server.php
~~~
php /data/wwwroot/default/swoole_file_frontend/demo/server.php
~~~
5.前端文件准备，因为是消息推送模拟，需要一个页面admin.html做后端消息推送页面，另外一个页面client.html做用户客户端消息接收页面，核心内容差不多，样式可以替换
admin.html
