[PHP知识库]thinkphp6+workerman 小demo

正常安装

composer require topthink/think-worker`

如果出现异常 报错

?在项目根目录下面的composer.json 文件中设置

"topthink/think-worker": "^3.0",

之后?

composer install 

如果还出现异常 忽略版本更新

composer install --ignore-platform-reqs 

安装成功后

在项目路径下的cofing 文件下找到?config/worker_server.php

只需要动这一个文件

'protocol'       => 'websocket', // 协议 支持 tcp udp unix http websocket text
'host'           => '0.0.0.0', // 监听地址
'port'           => 2346, // 监听端口
'socket'         => '', // 完整监听地址
'context'        => [], // socket 上下文选项
'worker_class'   => 'app\work\Push', // 自定义Workerman服务类名 支持数组定义多个服务

只需要修改worker_class 更改为我们书写的文件绝对路径但是不要后缀 也可以写数组的形式

worker实现 `app/work/Push.php`

只是简单的例子练习

代码如下：

<?php
namespace app\work;
use think\worker\Server;
use Workerman\Lib\Timer;
use think\facade\Db;
class Push extends Server
{
      protected $socket = 'http://0.0.0.0:2346';   //端口自行修改

 
    protected static $heartbeat_time    =   55;
 
    public function onWorkerStart($worker){
        
        //查看是否有新的充值或提现订单，有就推送给所有用户
        Timer::add(3, function()use($worker){
 
            $time_now   =   time();
            $hasNewDepositOrder   =   Db::name('deposit_order')->where('is_push',0)->order('id desc')->count('id');
  
 
            if($hasNewDepositOrder){
                $depositOrderInfo   =   Db::name('deposit_order')->where('is_push',0)->order('id desc')->find();
               
                $data   =   ['money'=>$depositOrderInfo['pay_amount'],'type'=>'deposit'];
                foreach($worker->connections as $connection) {
                    if(empty($connection->lastMessageTime)){
                        $connection->lastMessageTime =   $time_now;
                    }
 
                    if($time_now-$connection->lastMessageTime > self::$heartbeat_time){
                        $connection->close();
                    }
 
                    $connection->send(json_encode($data));
                }
 
               Db::name('deposit_order')->where('id',$depositOrderInfo['id'])->save(['is_push'=>1]);
            }else{
                foreach($worker->connections as $connection) {
                    if(empty($connection->lastMessageTime)){
                        $connection->lastMessageTime = $time_now;
                        continue;
                    }
 
                    if($time_now-$connection->lastMessageTime > self::$heartbeat_time){      //连接超时
                        $connection->close();
                    }
                }
            }
        });
    }
}

启动 每次修改 文件后 最好是从新启动一下服务

php think worker:server start 开启

php think worker:server stop  结束

php think worker:server status  查看状态

?js代码: 随便搞一个静态页面就可以

<script>
            let ws = new WebSocket("ws://换成自己的服务器的IP:2346")
             
            ws.onopen = function() {  //绑定连接事件
                console.log("连接成功");
                //每30秒发送一次心跳
                setInterval(function(){
                    ws.send('123');
                    console.log('发送心跳...');
                },30000)
            };
            ws.onmessage = function (s){
                console.log(s);
            }
            ws.onclose = function(evt) { //绑定关闭或断开连接事件
            　　console.log("连接已关闭");
            };
        </script>

因为上面是根据数据库的信息插入来进行判断了 所以我们通过结构去表中增加数据在前台的 onmessage 中就可以打印出来数据展示

直接通过数据库的新增数据，就可以把对应的信息展示出来 具体逻辑就是push.php中写的数据库展示逻辑

sql 随便搞的 只是为了能够实现 当数据库添加 能够把数据交互到前台

SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;
