Swoole Brief introduction

  • C语言编写PHP扩展(so文件)
  • 异步,并行(多线程),高性能网络通信引擎
  • 协程
  • 应用: 互联网,网络游戏,聊天室,在线直播

Environment construction

gcc autoconfig
tar -jxvf php-7.2.7.tar.bz2
./configure & make & make install 
vim ~/.bash_profile
source ~/.bash_profile
php.ini文件存放位置
[root@bogon php]# php -i | grep php.ini
Configuration File (php.ini) Path => /home/work/soft/php/lib

Swoole Install

git clone https://gitee.com/swoole/swoole.git
phpize
./configure --with-php-config=/home/work/soft/php/bin/php-config
make & make install

Tcp Server

查看进程个数
·ps aft | grep tcp.php·

<?php

//创建Server对象,监听 127.0.0.1:9501端口
$serv = new swoole_server("127.0.0.1", 9501);

$serv->set([
    'worker_num' => 6 , // worker进程数 cpu 1-4
    'max_request' => 10000,
]);
//监听连接进入事件
/**
 * $fd 客户端连接的唯一标示
 * $reactor_id 线程id
 */
$serv->on('connect', function ($serv, $fd, $reactor_id) {
    echo "Client: {$reactor_id} - {$fd}-Connect.\n";
});

//监听客户端发送来的数据,接收事件
$serv->on('receive', function ($serv, $fd, $reactor_id, $data) {
    // 向客户端发送数据
    $serv->send($fd, "Server: {$reactor_id} - {$fd}".$data);
});

//监听连接关闭事件
$serv->on('close', function ($serv, $fd) {
    echo "Client: Close.\n";
});

//启动服务器
$serv->start();

TCP Client

<?php
// 连接 swoole tcp 服务
$client = new swoole_client(SWOOLE_SOCK_TCP);

if(!$client->connect("127.0.0.1", 9501)) {
    echo "连接失败";
    exit;
}

/// php cli常量
fwrite(STDOUT, "请输入消息:");
$msg = trim(fgets(STDIN));

// 发送消息给 tcp server服务器
$client->send($msg);

// 接受来自server 的数据
$result = $client->recv();
echo $result;

Http service

// 0.0.0.0b表示监听所有地址
$http = new swoole_http_server("0.0.0.0", 8811);

$http->set(
    [
        // 如果是静态文件,不走下面的数据逻辑
        'enable_static_handler' => true,
        // 静态资源存放路径
        'document_root' => "/home/work/hdtocs/swoole_mooc/data",
    ]
);
$http->on('request', function($request, $response) {
    //print_r($request->get);
    $content = [
        'date:' => date("Ymd H:i:s"),
        'get:' => $request->get,
        'post:' => $request->post,
        'header:' => $request->header,
    ];

    swoole_async_writefile(__DIR__."/access.log", json_encode($content).PHP_EOL, function($filename){
        // todo
    }, FILE_APPEND);
    $response->cookie("hanxiao", "xsssss", time() + 1800);
    $response->end("It's fucking end ". json_encode($request->get));
});

$http->start();

Swoole Websocket

});

$server->on('close', function ($ser, $fd) {
    echo "client {$fd} closed\n";

$server->start();

优化 Swoole Task

客户端不用等待Task完成
