這篇文章主要介紹了ThinkPHP5.0框架結(jié)合Swoole開(kāi)發(fā)實(shí)現(xiàn)WebSocket在線聊天,結(jié)合完整案例形式詳細(xì)分析了thinkPHP5擴(kuò)展Swoole實(shí)現(xiàn)WebSocket在線聊天相關(guān)步驟、操作技巧與注意事項(xiàng),需要的朋友可以參考下

本文實(shí)例講述了ThinkPHP5.0框架結(jié)合Swoole開(kāi)發(fā)實(shí)現(xiàn)WebSocket在線聊天案例。分享給大家供大家參考，具體如下：

ThinkPHP使用Swoole需要安裝 think-swoole Composer包，前提系統(tǒng)已經(jīng)安裝好了Swoole PECL 拓展（相關(guān)文章：Linux下源碼包安裝使用Swoole擴(kuò)展）

在tp5的項(xiàng)目根目錄下執(zhí)行composer命令安裝think-swoole：

composer require topthink/think-swoole

安裝成功：

話不多說(shuō)，直接上代碼：

新建WebSocket.php控制器：

（監(jiān)聽(tīng)端口要確認(rèn)服務(wù)器放行，寶塔環(huán)境還需要添加安全組規(guī)則）

<?php

namespace app\home\controller;
use think\swoole\Server;
class WebSocket extends Server
{
  protected $host = '0.0.0.0'; //監(jiān)聽(tīng)所有地址
  protected $port = 9501; //監(jiān)聽(tīng)9501端口
  protected $serverType = 'socket';
  protected $option = [ 
    'worker_num'=> 4, //設(shè)置啟動(dòng)的Worker進(jìn)程數(shù)
    'daemonize'	=> false, //守護(hù)進(jìn)程化（上線改為true）
    'backlog'	=> 128, //Listen隊(duì)列長(zhǎng)度
    'dispatch_mode' => 2, //固定模式，保證同一個(gè)連接發(fā)來(lái)的數(shù)據(jù)只會(huì)被同一個(gè)worker處理

    //心跳檢測(cè)：每60秒遍歷所有連接，強(qiáng)制關(guān)閉10分鐘內(nèi)沒(méi)有向服務(wù)器發(fā)送任何數(shù)據(jù)的連接
    'heartbeat_check_interval' => 60,
    'heartbeat_idle_time' => 600
  ];

  //建立連接時(shí)回調(diào)函數(shù)
  public function onOpen($server,$req)
  {
    $fd = $req->fd;//客戶(hù)端標(biāo)識(shí)
    $uid = $req->get['uid'];//客戶(hù)端傳遞的用戶(hù)id
    $token = $req->get['token'];//客戶(hù)端傳遞的用戶(hù)登錄token
    
    //省略token驗(yàn)證邏輯......
    if (!$token) {
      $arr = array('status'=>2,'message'=>'token已過(guò)期');
      $server->push($fd, json_encode($arr));
      $server->close($fd);
      return;
    }
    //省略給用戶(hù)綁定fd邏輯......
    echo "用戶(hù){$uid}建立了連接,標(biāo)識(shí)為{$fd}\n";
  }

  //接收數(shù)據(jù)時(shí)回調(diào)函數(shù)
  public function onMessage($server,$frame)
  {
    $fd = $frame->fd;
    $message = $frame->data;

    //省略通過(guò)fd查詢(xún)用戶(hù)uid邏輯......
    $uid = 666;
    $data['uid'] = $uid;
    $data['message'] = '用戶(hù)'.$uid.'發(fā)送了:'.$message;
    $data['post_time'] = date("m/d H:i",time());
    $arr = array('status'=>1,'message'=>'success','data'=>$data);

    //僅推送給當(dāng)前連接用戶(hù)
    //$server->push($fd, json_encode($arr));
    
    //推送給全部連接用戶(hù)
    foreach($server->connections as $fd) {
      $server->push($fd, json_encode($arr));
    } 
  }

  //連接關(guān)閉時(shí)回調(diào)函數(shù)
  public function onClose($server,$fd)
  {
    echo "標(biāo)識(shí){$fd}關(guān)閉了連接\n";
  }
}
