tp5.0配置workerman实现简单聊天功能
compopser安装workerman
composer require topthink/think-worker=1.0.*
Windows系统需要
composer require workerman/workerman-for-win
出现以上界面代表应该安装成功了
在项目目录下新建server.php
#!/usr/bin/env php
<?php
define('APP_PATH', __DIR__ . '/application/');
define('BIND_MODULE','push/Worker');
// 加载框架引导文件
require __DIR__ . '/thinkphp/start.php';
新建worker类
<?php
namespace app\push\controller;
use think\worker\Server;
class Worker extends Server
{
protected $socket = 'websocket://push.app:2346';
/**
* 收到信息
* @param $connection
* @param $data
*/
public function onMessage($connection, $data)
{
$connection->send('我收到你的信息了');
}
/**
* 当连接建立时触发的回调函数
* @param $connection
*/
public function onConnect($connection)
{
}
/**
* 当连接断开时触发的回调函数
* @param $connection
*/
public function onClose($connection)
{
}
/**
* 当客户端的连接上发生错误时触发
* @param $connection
* @param $code
* @param $msg
*/
public function one rror($connection, $code, $msg)
{
echo "error $code $msg\n";
}
/**
* 每个进程启动
* @param $worker
*/
public function onWorkerStart($worker)
{
}
}
项目根目录cmd,输入php server.php
测试
浏览器下F12输入
ws = new WebSocket(“ws://push.app:2346”);
ws.onopen = function() {
alert(“连接成功”);
ws.send(‘tom’);
alert(“给服务端发送一个字符串：tom”);
};
ws.onmessage = function(e) {
alert(“收到服务端的消息：” + e.data);
};
继续测试
ws.send(‘保持连接，发第二次信息，查看服务器回应’);
实现简单聊天功能
1、新建woker控制器
<?php
namespace app\push\controller;
use think\worker\Server;
use Workerman\Worker as Work;
class Worker extends Server
{
protected $socket = 'websocket://www.tp5.0.com:2346';
protected $processes = 1;
protected $uidConnections = array();
static $count = 0;
/**
* 收到信息
* @param $connection
* @param $data
*/
public function onMessage($connection, $data)
{
// 判断当前客户端是否已经验证,既是否设置了uid，设置了直接发送消息，未设置第一次为设置uid
if(!isset($connection->uid))
{
// 没验证的话把第一个包当做uid（这里为了方便演示，没做真正的验证）
$connection->uid = $data;
/* 保存uid到connection的映射，这样可以方便的通过uid查找connection，
* 实现针对特定uid推送数据
*/
$this->uidConnections[$connection->uid] = $connection;
$data = '用户 '.$connection->uid.'加入房间 ||'.self::$count;
$this->broadcast($data);
return;
}else{
$data = '用户 '.$connection->uid.':'.$data.'||'.self::$count;
$this->broadcast($data);
}
}
/**
* 当连接建立时触发的回调函数
* @param $connection
*/
public function onConnect($connection)
{
self::$count++;
}
/**
* 当连接断开时触发的回调函数
* @param $connection
*/
public function onClose($connection)
{
self::$count--;
if(isset($connection->uid))
{
// 连接断开时删除映射
$data = '用户 '.$connection->uid.'退出房间 ||'.self::$count;
$this->broadcast($data);
unset($this->uidConnections[$connection->uid]);
}
}
/**
* 当客户端的连接上发生错误时触发
* @param $connection
* @param $code
* @param $msg
*/
public function one rror($connection, $code, $msg)
{
echo "error $code $msg\n";
}
/**
* 每个进程启动
* @param $worker
*/
public function onWorkerStart($socket)
{
}
// 向所有验证的用户推送数据
function broadcast($message)
{
foreach($this->uidConnections as $connection)
{
$connection->send($message);
}
}
// 针对uid推送数据
function sendMessageByUid($uid, $message)
{
if(isset($this->uidConnections[$uid]))
{
$connection = $this->uidConnections[$uid];
$connection->send($message);
return true;
}
return false;
}
}
2、Index控制器
<?php
namespace app\index\controller;
use think\Controller;
class Index extends Controller
{
public function index(){
$name=$_GET['name'];
$this->assign('name',$name);
return $this->fetch();
}
}
3、index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>聊天室</title>
</head>
<body>
<div class="title" style="display: inline-block">当前聊天室<span id="count">0</span>人</div>
<hr/>
<div id="aaa" class="conten title"></div>
<div class="fasong title">
<textarea id="textxinxi" class="xinxi"></textarea>
<input type="button" value="发送" class="fasongbtn" onclick="fasong()">
</div>
<script>
var name = "{$name}";
ws = new WebSocket("ws://www.tp5.com:2346");
ws.onopen = function() {
var uid = name;
ws.send(uid);
};
ws.onmessage = function(e) {
var aaa = document.getElementById('aaa');
var count = document.getElementById('count');
var data = e.data.split('||')[0];//根据||截取字符串，前面为放内容，后面为当前聊天室人数
var count1 = e.data.split('||')[1];
aaa.innerHTML += data + '<br/>';// 插入新的两天内容
count.innerHTML = count1;// 修改聊天室人数
};
function fasong() {
let textxinxi = document.getElementById('textxinxi').value;
let text = '';
document.getElementById('textxinxi').value = text;//发送新内容
ws.send(textxinxi);
}
</script>
</body>
</html>
