composer require topthink/think-swoole

命令行

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

服务启动

当你在命令行 php think swoole 下执行实现之后就会启动一个 HTTP Server,能够间接拜访以后的利用

'server'     => ['host'      => env('SWOOLE_HOST', '0.0.0.0'), // 监听地址
    'port'      => env('SWOOLE_PORT', 9501), // 监听端口
    'mode'      => SWOOLE_PROCESS, // 运行模式 默认为 SWOOLE_PROCESS
    'sock_type' => SWOOLE_SOCK_TCP, // sock type 默认为 SWOOLE_SOCK_TCP
    'options'   => [
        // 服务启动后,过程 ID 寄存文件
        'pid_file'              => runtime_path() . 'swoole.pid',
        // swoole 的日志文件
        'log_file'              => runtime_path() . 'swoole.log',
        // 守护过程模式设置 true 后盾运行
        'daemonize'             => false,
        // 设置启动的 reactor 线程数
        'reactor_num'           => swoole_cpu_num(),
        // 设置启动的 worker 过程数
        'worker_num'            => swoole_cpu_num(),
        // 配置 Task 过程的数量
        'task_worker_num'       => swoole_cpu_num(),
        // 开启动态文件申请解决,需配合 document_root
        'enable_static_handler' => true,
        // 动态文件根目录
        'document_root'         => root_path('public'),
        // 设置最大数据包尺寸,单位字节
        'package_max_length'    => 20 * 1024 * 1024,
        // 配置发送输入缓冲区内存尺寸
        'buffer_output_size'    => 10 * 1024 * 1024,
        // 设置客户端连贯最大容许占用的内存数量
        'socket_buffer_size'    => 128 * 1024 * 1024,
    ],
],

热更新

swoole 服务器运行过程中 php 文件是常驻内存运行,这样就能够防止反复的读取磁盘,反复的解释编译 php,以便达到最高的性能,所以批改代码须要重启服务

think-swoole 扩大提供热更新性能,在检测相干文件有更新会主动重启,不在须要手动实现重启,不便开发调试

生产环境下不倡议开始文件监控,性能损耗,失常状况下你所批改的文件须要确认无误能力进行更新部署

.env外面设置 APP_DEBUG = true 会默认开启热更新

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

参数阐明

参数 阐明
enable 是否开启热更新
name 监听哪些类型的文件变动
include 监听哪些目录下的文件变动
exclude 排除目录

websocket

先来一个官网的例子

$server = new Swoole\WebSocket\Server("0.0.0.0", 9501);
$server->on('open', function (Swoole\WebSocket\Server $server, $request) {echo "server: handshake success with fd{$request->fd}\n";
});
$server->on('message', function (Swoole\WebSocket\Server $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} closed\n";
});
$server->start();

开启 think-swoole 的 websocket 性能 \config\swoole.php

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

创立三个事件

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

而后将这三个事件写到到事件监听中,别离有以下 2 中文件能够批改形式,留神二选一

thinkphp6 自带的事件绑定app\event.php

    'listen'    => [
        ........
        // 监听链接
        'swoole.websocket.Connect' => [\app\listener\SwWsConnect::class],
        // 敞开连贯
        'swoole.websocket.Close' => [\app\listener\SwWsClose::class],
        // 发送音讯场景
        'swoole.websocket.Message' => [\app\listener\SwWsMessage::class]
    ],

think-swoole 事件绑定config\swoole.php

'listen'        => [
    'connect'=>\app\listener\SwWsConnect::class,
    'close'=>\app\listener\SwWsClose::class,
    'message'=> \app\listener\SwWsMessage::class
],

怎么抉择是保留在 config\swoole.php 还是 app\event.php 配置中呢?

首先咱们 咱们确定一下咱们这个我的项目中存在有几个实时通信,

如果只是存在一个实时通信 集体倡议 保留在config\swoole.php

如果是存在多个实时通信,就保留在app\event.php

key 值 必须是swoole.websocket. 事件名称 例如 swoole.websocket.Message

开始写事件中中办法

连贯事件app\listener\SwWsConnect.php

public function handle($event, \think\swoole\websocket $ws)
{
    // 获取以后发送者的 fd
    $fd = $ws->getSender();
    echo "server: handshake success with fd{$fd}\n";
}

敞开事件app\listener\SwWsClose.php


public function handle($event, \think\swoole\websocket $ws)
{$fd = $ws->getSender();
    echo "client {$fd} closed\n";
}

message 事件app\listener\SwWsMessage.php

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

启动 php think swoole 进行测试

think-swoole 中的 websocket 办法总结

// 给本人发消息
$ws->emit("this is server", $ws->getSender());
// 给指定一个 fd 发消息
$ws->to($to)->emit("messagecallback",$data);
// 给指定多集体发消息
$ws->to([1,2,3])->emit("messagecallback",$data);
// 发送给所有的(不蕴含本人)
$ws->broadcast()->emit("messagecallback",$data);
// 模仿 formfd 给 tofd 发送音讯
$ws->setSender($formfd)->to($tofd)->emit("messagecallback",$data);

留神:在多个实时通信场景下应用 emit

第一个参数传入 传入 事件名称 callback 例如 messagecallback

如果你发现你 think-swoole 中有些没有 swoole 中的办法能够这么干

$sw = app('swoole.server');
$sw = app("think\swoole\Manager")->getServer();
// 以上二选一

$es = $sw->isEstablished($fd); // 查看连贯是否为无效的 WebSocket 客户端连贯
var_dump($es);

聊天室 room 实现

前端文件参考 html\room.htmlhtml\room-socket-io.html

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

事件绑定

// 退出房间
'swoole.websocket.RoomJoin' => [\app\listener\SwRoomJoin::class],
// 来到房间
'swoole.websocket.Roomleave' => [\app\listener\SwRoomLeave::class],
// 在房间发消息
'swoole.websocket.RoomMessage' => [\app\listener\SwRoomMessage::class]

退出房间逻辑

public function handle($event, \think\swoole\websocket $ws, \think\swoole\websocket\room $room)
{$fd = $ws->getSender();
    // 客户端如果定的 room
    $roomid = $event['room'];
    // 获取指定房间下有哪些客户端
    $roomfds = $room->getClients($roomid);
    // 判断这个房间有没有本人 如果有本人就不须要再次发送告诉
    if (in_array($fd, $roomfds)) {$ws->to($roomfds)->emit("roomjoincallback", "房间 {$roomid} 已退出");
        return;
    }
    // 退出房间
    $ws->join($roomid);
    $ws->to($roomfds)->emit("roomjoincallback", "{$fd}退出房间 {$roomid} 胜利");
}

来到房间逻辑

public function handle($event, \think\swoole\websocket $ws, \think\swoole\websocket\Room $room)
{$roomid = $event['room'];
    $fd = $ws->getSender();
    $roomfds = $room->getClients($roomid);
    if (!in_array($fd, $roomfds)) {$ws->emit("roomleavecallback", "{$fd}不在 {$roomid} 房间内,怎么来到~");
        return;
    }
    // 来到房间
    $ws->leave($roomid);
    // 获取以后客户端退出了哪些客户端
    $rooms = $room->getRooms($fd);
    $ws->to($roomfds)->emit("roomleavecallback", "{$fd}已来到了~~");
}

在房间公布聊天逻辑

    public function handle($event, \think\swoole\websocket $ws, \think\swoole\websocket\room $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} 房间内,无奈进入公布聊天~");
            return;
        }
        $ws->to($roomfds)->emit("roommessagecallback",  $text);
    }

事件订阅

php think make:listener SwSubscribe

applistenerSwSubscribe.php

<?php
declare (strict_types = 1);

namespace app\listener;

class SwSubscribe
{
    protected $ws = null;

    // public function __construct()
    // {//     $this->ws = app('think\swoole\Websocket');
    // }

    public function __construct(\think\Container $c)
    {$this->ws = $c->make(\think\swoole\Websocket::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} closed\n";
    }
    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);
    }
}

有点相似 将原生的 swoole 代码改成面向对象代码,失效办法 config\swoole.php中在subscribe 退出\app\listener\SwSubscribe::class

'subscribe'     => [\app\listener\SwSubscribe::class],

app\event.php 文件中的 swoole.websocket.Connect 相当于 app\listener\SwSubscribe.php文件中的 onConnect 函数。如果同时存在的存在的话,就会向客户端发送 2 次以上的音讯

Task 工作投递

https://wiki.swoole.com/#/sta…

生成事件

php think make:listener SwSendEmailTask

编写发送邮件办法app\listener\SwSendEmailTask.php

public function handle($event)
{var_dump($event);
    //
    echo "开发发送邮件".time();
    sleep(3);
    echo "完结发送邮件".time();}  

注册事件app\event.php

'swoole.task'=>[\app\listener\SwSendEmailTask::class],

在控制器中投递工作

public function doRegister()
{$server = app('swoole.server');
    $server->task(\app\listener\SwSendEmailTask::class);
    return "注册胜利";
}

public function doRegister(\think\swoole\Manager $manager)
{$server = $manager->getServer();
    $server->task(\app\listener\SwSendEmailTask::class);
    return "注册胜利";
}
public function doRegister(\Swoole\Server $server)
{$server->task(\app\listener\SwSendEmailTask::class);
    return "注册胜利";
}

三种获取\Swoole\Server, 任意选其一

在 swoole 中还有一个事件叫finish,它的作用就是把异步工作的后果返回,在 think-swool 是这么解决的

定义一个发送邮件异步工作处理结果的事件

php think make:listener SwSendEmailFinish

注册事件app\event.php

'swoole.finish'=>[\app\listener\SwSendEmailFinish::class],

在 task 工作中调用

public function handle($event)
{var_dump($event);
    //
    echo "开发发送邮件".time();
    sleep(3);
    echo "完结发送邮件".time();
    $event->finish(\app\listener\SwSendEmailFinish::class);
} 

高性能共享内存 Table

https://wiki.swoole.com/#/mem…

先定结构在进行操作数据(原生 swoole 操作)

$table = new Swoole\Table(1024);
// 创立表
$table->column("id", Swoole\Table::TYPE_INT);
$table->column("name", Swoole\Table::TYPE_STRING);
$table->column("money", Swoole\Table::TYPE_FLOAT);
$table->create();

// 增加数据
$table->set("zq", [
    'id' => 1,
    'name' => "zhiqiang",
    'money' => 100,
]);
// 获取一行数据
$table->get("zq");
// 批改数据
// 字段递增
$table->incr("zq","money",2);
// 递加
$table->decr("zq","money",2);
// 返回 table 中存在的条目数。$table->count();
// 遍历 table 中的数据
foreach($table as $item){var_dump($item);
}

think-swoole 中的操作

先对 table 表构造进行初始化config\swoole.php

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

            ],
        ],
    ],

操作数据

$table =  app('swoole.table.user');
$table->set("zq", [
    'id' => 1,
    'name' => "zhiqiang",
    'money' => 100
]);
// 获取一行数据
$table->get("zq");
// 批改数据
// 字段递增
$table->incr("zq", "money", 2);
// 递加
$table->decr("zq", "money", 2);
// 返回 table 中存在的条目数。$table->count();
// 遍历 table 中的数据
foreach ($table as $item) {var_dump($item);
}
// 查看 table 中是否存在某一个 key。$table->exist('zq');
// 获取理论占用内存尺寸, 单位字节
$table->momorySize();

RPC

RPC(Remote Procedure Call):近程过程调用,它是一种通过网络从近程计算机程序上申请服务,而不须要理解底层网络技术的思维。

具体介绍:https://developer.51cto.com/a…

  • 解决分布式系统中,服务之间的调用问题。
  • 近程调用时,要可能像本地调用一样不便,让调用者感知不到近程调用的逻辑。
  • 节点角色阐明:
  • Server: 裸露服务的服务提供方
  • Client: 调用近程服务的服务生产方
  • Registry: 服务注册与发现的注册核心

think-swoole 实现 RPC 性能

服务器端

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

<?php
namespace app\rpc\interfaces;
interface UserInterface
{public function create();
    public function find(int $id);
}

实现接口app/rpc/services/UserService.php

<?php
namespace app\rpc\services;
use app\rpc\interfaces\UserInterface;
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. "查问数据遍历";
    }
}

注册 rpc 服务config/swoole.php

    'rpc'        => [
        'server' => [
            // 开启 rpc 服务
            'enable'   => true,
            //rpc 端口
            'port'     => 9000,
            'services' => [
                // 注册服务
                \app\rpc\services\UserService::class
            ],
        ],
        // 如果填写也是能够调用其余服务端
        'client' => [],],

启动服务端

php think swoole start /  php think swoole:rpc

客户端

    'rpc'        => ['server' => [],
        'client' => [
            'tp6'=>[
                // 服务端的 ip 地址
                'host'=>'127.0.0.1',
                // 服务端对应的端口
                'port'=>'9000'
            ]
            // 更多服务端
        ],
    ],

运行 php think rpc:interface 生成 RPC 接口文件app\rpc.php

<?php
/**
 * This file is auto-generated.
 */
declare(strict_types=1);
namespace rpc\contract\tp6;
interface UserInterface
{public function create();
    public function find(int $id);
}
return ['tp6' => ['rpc\contract\tp6\UserInterface']];

在控制器调用

    public function index(\rpc\contract\tp6\UserInterface $user)
    {
        //
        $user->find(1);
//        $user->create();}

定时工作

在 think-swoole 2.0 版本的时候还是反对自定义定时工作配置, 具体参考 https://github.com/top-think/…

在 3.0 就不反对了,在这里介绍一个通用的命令行启动定时工作

php think make:command SwooleTimer

加载命令行config/console.php

'commands' => [
    'swooletimer'=>app\command\SwooleTimer::class
    ...........
],

书写命令脚本app/command/SwooleTimer.php

<?php
declare (strict_types = 1);

namespace app\command;

use think\console\Command;
use think\console\input\Argument;


class SwooleTimer extends Command
{protected function configure()
    {
        // 指令配置
        $this->setName('app\command\swooletimer')
            ->addArgument('action', Argument::OPTIONAL, "start | stop", 'start')
            ->setDescription('Swoole Timer for ThinkPHP');
    }


    public function handle()
    {$action = $this->input->getArgument('action');
        if (in_array($action, ['start','stopall'])) {$this->app->invokeMethod([$this, $action], [], true);
        } else {$this->output->writeln("<error>Invalid argument action:{$action}, Expected start</error>");
        }
    }

    /**
     * 启动定时工作 次要工作打算在这里书写
     */
    protected function start()
    {
        // https://wiki.swoole.com/#/timer
        $timer_id=swoole_timer_tick(2000,function (){echo "2s 循环执行须要做的事件".time()."\n";
        });
        $this->output->writeln("Swoole Timer_id:{$timer_id}");
    }

    /**
     * 革除所有的定时工作
     */
    protected  function stop(){swoole_timer_clear_all();
        $this->output->writeln("Swoole Timer  clear all ok");
    }
}
