安裝

composer require topthink/think-swoole

命令行

php think swoole [start|stop|reload|restart]

服務(wù)啟動

當(dāng)你在命令行php think swoole下執(zhí)行完成之后就會啟動一個HTTP Server，可以直接訪問當(dāng)前的應(yīng)用【推薦教程：thinkphp】

'server'     => [     'host'      => env('SWOOLE_HOST', '0.0.0.0'), // 監(jiān)聽地址     'port'      => env('SWOOLE_PORT', 9501), // 監(jiān)聽端口     'mode'      => SWOOLE_PROCESS, // 運(yùn)行模式 默認(rèn)為SWOOLE_PROCESS     'sock_type' => SWOOLE_SOCK_TCP, // sock type 默認(rèn)為SWOOLE_SOCK_TCP     'options'   => [         // 服務(wù)啟動后，進(jìn)程ID存放文件         'pid_file'              => runtime_path() . 'swoole.pid',         // swoole 的日志文件         'log_file'              => runtime_path() . 'swoole.log',         // 守護(hù)進(jìn)程模式設(shè)置 true 后臺運(yùn)行         'daemonize'             => false,         // 設(shè)置啟動的reactor線程數(shù)         'reactor_num'           => swoole_cpu_num(),         // 設(shè)置啟動的worker進(jìn)程數(shù)         'worker_num'            => swoole_cpu_num(),         //配置Task進(jìn)程的數(shù)量         'task_worker_num'       => swoole_cpu_num(),         //開啟靜態(tài)文件請求處理，需配合document_root         'enable_static_handler' => true,         //靜態(tài)文件根目錄         'document_root'         => root_path('public'),         // 設(shè)置最大數(shù)據(jù)包尺寸，單位字節(jié)         'package_max_length'    => 20 * 1024 * 1024,         //配置發(fā)送輸出緩沖區(qū)內(nèi)存尺寸         'buffer_output_size'    => 10 * 1024 * 1024,         //設(shè)置客戶端連接最大允許占用的內(nèi)存數(shù)量         'socket_buffer_size'    => 128 * 1024 * 1024,     ], ],

熱更新

swoole服務(wù)器運(yùn)行過程中php文件是常駐內(nèi)存運(yùn)行，這樣就可以避免重復(fù)的讀取磁盤，重復(fù)的解釋編譯php，以便達(dá)到最高的性能，所以修改代碼需要重啟服務(wù)

think-swoole擴(kuò)展提供熱更新功能，在檢測相關(guān)文件有更新會自動重啟，不在需要手動完成重啟，方便開發(fā)調(diào)試

生產(chǎn)環(huán)境下不建議開始文件監(jiān)控，性能損耗，正常情況下你所修改的文件需要確認(rèn)無誤才能進(jìn)行更新部署

.env里面設(shè)置APP_DEBUG = true會默認(rèn)開啟熱更新

'hot_update' => [     'enable'  => env('APP_DEBUG', false),     'name'    => ['*.php'],     'include' => [app_path()],     'exclude' => [], ],

參數(shù)說明

websocket

先來一個官方的例子

$server = new SwooleWebSocketServer("0.0.0.0", 9501); $server->on('open', function (SwooleWebSocketServer $server, $request) {     echo "server: handshake success with fd{$request->fd}n"; }); $server->on('message', function (SwooleWebSocketServer $server, $frame) {     echo "receive from {$frame->fd}:{$frame->data}n";     $server->push($frame->fd, "this is server"); }); $server->on('close', function ($ser, $fd) {     echo "client {$fd} closedn"; }); $server->start();

開啟think-swoole的websocket功能 configswoole.php

'websocket'  => [     'enable'        => true, ],

創(chuàng)建三個事件

php think make:listener SwWsConnect php think make:listener SwWsClose php think make:listener SwWsMessage

然后將這三個事件寫到到事件監(jiān)聽中，分別有以下2中文件可以修改方式，注意二選一

thinkphp6自帶的事件綁定appevent.php

    'listen'    => [         ........         // 監(jiān)聽鏈接         'swoole.websocket.Connect' => [             applistenerSwWsConnect::class         ],         //關(guān)閉連接         'swoole.websocket.Close' => [             applistenerSwWsClose::class         ],         //發(fā)送消息場景         'swoole.websocket.Message' => [             applistenerSwWsMessage::class         ]     ],

think-swoole事件綁定configswoole.php

'listen'        => [     'connect'=>applistenerSwWsConnect::class,     'close'=>applistenerSwWsClose::class,     'message'=> applistenerSwWsMessage::class ],

怎么選擇是保存在configswoole.php還是appevent.php配置中呢？

首先我們 我們確定一下我們這個項目中存在有幾個實時通訊，

如果只是存在一個實時通訊 個人建議 保存在configswoole.php

如果是存在多個實時通訊，就保存在appevent.php

key值 必須是swoole.websocket.事件名稱 例如 swoole.websocket.Message

開始寫事件中中方法

連接事件applistenerSwWsConnect.php

public function handle($event, thinkswoolewebsocket $ws) {     // 獲取當(dāng)前發(fā)送者的fd     $fd = $ws->getSender();     echo "server: handshake success with fd{$fd}n"; }

關(guān)閉事件applistenerSwWsClose.php

public function handle($event, thinkswoolewebsocket $ws) {     $fd = $ws->getSender();     echo "client {$fd} closedn"; }

message事件applistenerSwWsMessage.php

public function handle($event, thinkswoolewebsocket $ws) {     $fd = $ws->getSender();     $data = json_encode($event);     echo "receive from {$fd}:{$data}n";     $ws->emit("this is server", $fd); }

啟動php think swoole進(jìn)行測試

think-swoole中的websocket方法總結(jié)

//給自己發(fā)消息 $ws->emit("this is server", $ws->getSender()); //給指定一個fd發(fā)消息 $ws->to($to)->emit("messagecallback",$data); //給指定多個人發(fā)消息 $ws->to([1,2,3])->emit("messagecallback",$data); //發(fā)送給所有的(不包含自己) $ws->broadcast()->emit("messagecallback",$data); //模擬formfd 給tofd 發(fā)送消息 $ws->setSender($formfd)->to($tofd)->emit("messagecallback",$data);

注意：在多個實時通訊場景下使用 emit

第一個參數(shù)傳入 傳入 事件名稱callback 例如 messagecallback

如果你發(fā)現(xiàn)你think-swoole中有些沒有swoole中的方法可以這么干

$sw = app('swoole.server'); $sw = app("thinkswooleManager")->getServer(); //以上二選一  $es = $sw->isEstablished($fd); //檢查連接是否為有效的WebSocket客戶端連接 var_dump($es);

聊天室room實現(xiàn)

前端文件參考 htmlroom.html 或 htmlroom-socket-io.html

php think make:listener SwRoomJoin php think make:listener SwRoomLeave php think make:listener SwRoomMessage

事件綁定

// 加入房間 'swoole.websocket.RoomJoin' => [     applistenerSwRoomJoin::class ], // 離開房間 'swoole.websocket.Roomleave' => [     applistenerSwRoomLeave::class ], // 在房間發(fā)消息 'swoole.websocket.RoomMessage' => [     applistenerSwRoomMessage::class ]

加入房間邏輯

public function handle($event, thinkswoolewebsocket $ws, thinkswoolewebsocketroom $room) {     $fd = $ws->getSender();     //客戶端假如定的room     $roomid = $event['room'];     //獲取指定房間下有哪些客戶端     $roomfds = $room->getClients($roomid);     // 判斷這個房間有沒有自己 如果有自己就不需要再次發(fā)送通知     if (in_array($fd, $roomfds)) {         $ws->to($roomfds)->emit("roomjoincallback", "房間{$roomid}已加入");         return;     }     //加入房間     $ws->join($roomid);     $ws->to($roomfds)->emit("roomjoincallback", "{$fd}加入房間{$roomid}成功"); }

離開房間邏輯

public function handle($event, thinkswoolewebsocket $ws, thinkswoolewebsocketRoom $room) {     $roomid = $event['room'];     $fd = $ws->getSender();     $roomfds = $room->getClients($roomid);     if (!in_array($fd, $roomfds)) {         $ws->emit("roomleavecallback", "{$fd}不在{$roomid}房間內(nèi)，怎么離開~");         return;     }     //離開房間     $ws->leave($roomid);     //獲取當(dāng)前客戶端加入了哪些客戶端     $rooms = $room->getRooms($fd);     $ws->to($roomfds)->emit("roomleavecallback", "{$fd}已離開了~~"); }

在房間發(fā)布聊天邏輯

    public function handle($event, thinkswoolewebsocket $ws, thinkswoolewebsocketroom $room)     {         //         $roomid = $event['room'];         $text = $event['text'];         $fd = $ws->getSender();         $roomfds = $room->getClients($roomid);         if (!in_array($fd, $roomfds)) {             $ws->emit("roommessagecallback", "{$fd}不在{$roomid}房間內(nèi)，無法進(jìn)入發(fā)布聊天~");             return;         }         $ws->to($roomfds)->emit("roommessagecallback",  $text);     }

事件訂閱

php think make:listener SwSubscribe

applistenerSwSubscribe.php

<?php declare (strict_types = 1);  namespace applistener;  class SwSubscribe {     protected $ws = null;      // public function __construct()     // {     //     $this->ws = app('thinkswooleWebsocket');     // }      public function __construct(thinkContainer $c)     {         $this->ws = $c->make(thinkswooleWebsocket::class);     }          public function onConnect()     {         $fd = $this->ws->getSender();         echo "server: handshake success with fd{$fd}n";     }     public function onClose()     {         $fd = $this->ws->getSender();         echo "client {$fd} closedn";     }     public function onMessage($event)     {         $fd = $this->ws->getSender();         var_dump($event);         echo "server: handshake success with fd{$fd}n";         $this->ws->emit("this is server", $fd);     } }

有點(diǎn)類似 將原生的swoole代碼改成面向?qū)ο蟠a，生效方法 configswoole.php中在subscribe 加入applistenerSwSubscribe::class

'subscribe'     => [     applistenerSwSubscribe::class ],

在appevent.php文件中的 swoole.websocket.Connect 相當(dāng)于 applistenerSwSubscribe.php文件中的onConnect函數(shù)。如果同時存在的存在的話，就會向客戶端發(fā)送2次以上的消息

Task任務(wù)投遞

https://wiki.swoole.com/#/start/start_task

生成事件

php think make:listener SwSendEmailTask

編寫發(fā)送郵件方法applistenerSwSendEmailTask.php

public function handle($event) {     var_dump($event);     //     echo "開發(fā)發(fā)送郵件".time();     sleep(3);     echo "結(jié)束發(fā)送郵件".time(); }

注冊事件appevent.php

'swoole.task'=>[     applistenerSwSendEmailTask::class ],

在控制器中投遞任務(wù)

public function doRegister() {     $server = app('swoole.server');     $server->task(applistenerSwSendEmailTask::class);     return "注冊成功"; }  public function doRegister(thinkswooleManager $manager) {     $server = $manager->getServer();     $server->task(applistenerSwSendEmailTask::class);     return "注冊成功"; } public function doRegister(SwooleServer $server) {     $server->task(applistenerSwSendEmailTask::class);     return "注冊成功"; }

三種獲取SwooleServer,任意選其一

在swoole中還有一個事件叫finish，它的作用就是把異步任務(wù)的結(jié)果返回，在think-swool是這么處理的

定義一個發(fā)送郵件異步任務(wù)處理結(jié)果的事件

php think make:listener SwSendEmailFinish

注冊事件appevent.php

'swoole.finish'=>[     applistenerSwSendEmailFinish::class ],

在task任務(wù)中調(diào)用

public function handle($event) {     var_dump($event);     //     echo "開發(fā)發(fā)送郵件".time();     sleep(3);     echo "結(jié)束發(fā)送郵件".time();     $event->finish(applistenerSwSendEmailFinish::class); }

高性能共享內(nèi)存 Table

https://wiki.swoole.com/#/mem…

先定結(jié)構(gòu)在進(jìn)行操作數(shù)據(jù)（原生swoole操作）

$table = new SwooleTable(1024); //創(chuàng)建表 $table->column("id", SwooleTable::TYPE_INT); $table->column("name", SwooleTable::TYPE_STRING); $table->column("money", SwooleTable::TYPE_FLOAT); $table->create();  //添加數(shù)據(jù) $table->set("zq", [     'id' => 1,     'name' => "zhiqiang",     'money' => 100, ]); //獲取一行數(shù)據(jù) $table->get("zq"); // 修改數(shù)據(jù) // 字段遞增 $table->incr("zq","money",2); //遞減 $table->decr("zq","money",2); // 返回 table 中存在的條目數(shù)。 $table->count(); //遍歷table中的數(shù)據(jù) foreach($table as $item){     var_dump($item); }

think-swoole中的操作

先對table表結(jié)構(gòu)進(jìn)行初始化configswoole.php

    'tables'     => [         'user'=>[             'size'=>1024,             'columns'=>[                 [                     'name'=>'id',                     'type'=>SwooleTable::TYPE_INT                 ],                 [                     'name'=>'name',                     'type'=>SwooleTable::TYPE_STRING,                     'size'=>32                 ],                 [                     'name'=>'money',                     'type'=>SwooleTable::TYPE_FLOAT                 ],              ],         ],     ],

操作數(shù)據(jù)

$table =  app('swoole.table.user'); $table->set("zq", [     'id' => 1,     'name' => "zhiqiang",     'money' => 100 ]); //獲取一行數(shù)據(jù) $table->get("zq"); // 修改數(shù)據(jù) // 字段遞增 $table->incr("zq", "money", 2); //遞減 $table->decr("zq", "money", 2); // 返回 table 中存在的條目數(shù)。 $table->count(); //遍歷table中的數(shù)據(jù) foreach ($table as $item) { var_dump($item); } // 檢查 table 中是否存在某一個 key。 $table->exist('zq'); //獲取實際占用內(nèi)存尺寸,單位字節(jié) $table->momorySize();

RPC

RPC(Remote Procedure Call)：遠(yuǎn)程過程調(diào)用，它是一種通過網(wǎng)絡(luò)從遠(yuǎn)程計算機(jī)程序上請求服務(wù)，而不需要了解底層網(wǎng)絡(luò)技術(shù)的思想。

詳細(xì)介紹：https://developer.51cto.com/a…

• 解決分布式系統(tǒng)中，服務(wù)之間的調(diào)用問題。
• 遠(yuǎn)程調(diào)用時，要能夠像本地調(diào)用一樣方便，讓調(diào)用者感知不到遠(yuǎn)程調(diào)用的邏輯。
• 節(jié)點(diǎn)角色說明：
• Server: 暴露服務(wù)的服務(wù)提供方
• Client: 調(diào)用遠(yuǎn)程服務(wù)的服務(wù)消費(fèi)方
• Registry: 服務(wù)注冊與發(fā)現(xiàn)的注冊中心

think-swoole實現(xiàn)RPC功能

服務(wù)器端

接口定義app/rpc/interfaces/UserInterface.php

<?php namespace apprpcinterfaces; interface UserInterface {     public function create();     public function find(int $id); }

實現(xiàn)接口app/rpc/services/UserService.php

<?php namespace apprpcservices; use apprpcinterfacesUserInterface; class UserService implements UserInterface {     public function create()     {         // TODO: Implement create() method.         return "service create success";     }     public function find(int $id)     {         // TODO: Implement find() method.         return $id. "查詢數(shù)據(jù)遍歷";     } }

注冊rpc服務(wù)config/swoole.php

    'rpc'        => [         'server' => [             //開啟rpc服務(wù)             'enable'   => true,             //rpc端口             'port'     => 9000,             'services' => [                 //注冊服務(wù)                 apprpcservicesUserService::class             ],         ],         // 如果填寫也是可以調(diào)用其他服務(wù)端         'client' => [         ],     ],

啟動服務(wù)端

php think swoole start /  php think swoole:rpc

客戶端

    'rpc'        => [         'server' => [         ],         'client' => [             'tp6'=>[                 //服務(wù)端的ip地址                 'host'=>'127.0.0.1',                 //服務(wù)端對應(yīng)的端口                 'port'=>'9000'             ]             //
