Swoole 整合 Laravel

php常见运行方式

1. php + module + apache
2. php + php-fpm + nginx

传统运行方式优点

1. 每次都是新的请求，运行完即释放，不占用内存

传统运行方式缺点

1. 每次都需要composer 引入文件
2. DB contention 开销大，每次运行都要建立连接和执行查询，大多数性能消耗在连接上

基于swoole http 容器

swoole 有一个优点就是他可以常驻内存，不需要反复引用，类似于JAVA里的Spring Boot DB contention 也可以有连接池不需要每次执行完就断开连接，减少连接次数。

整合代码

安装swoole扩展 …略

将代码放入laravel 框架下的public目录下

<?php

use Symfony\Component\HttpFoundation\ParameterBag;

$server = new Swoole\Http\Server('0.0.0.0',8000);
$app = null;

$server->set([
    'http_parse_post' => true,
    'document_root' => __DIR__,
    'enable_static_handler' => true,
]);

$server->on('WorkerStart',function () {

    global $app;
    require __DIR__.'/../vendor/autoload.php';
    $app = require_once __DIR__.'/../bootstrap/app.php';
});

$server->on('Request',function (\Swoole\Http\Request $sRequest ,\Swoole\Http\Response $sResponse) {

    global $app;
    $_GET = $sRequest->get??[];
    $_POST = $sRequest->post?? [];
    $_COOKIE = $sRequest->cookie ??[];
    $_FILES = $sRequest->files ?? [];
    foreach ($sRequest->server as $key => $value) {

        $_SERVER[strtoupper($key)] = $value;
    }
    $kernel = $app->make(Illuminate\Contracts\Http\Kernel::class);
    $request = Illuminate\Http\Request::capture();
    foreach ($sRequest->header as $key => $value) {

        $request->headers->set($key,explode(';',$value));
    }
    if ($request->isJson() && $sRequest->rawContent()) {

        $request->setJson(new ParameterBag(json_decode($sRequest->rawContent(),true)));
    }
    $response = $kernel->handle($request);
    foreach ($response->headers->allPreserveCaseWithoutCookies() as $key => $item) {

        $value = implode(";",$item);
        $sResponse->header($key,$value);
    }
    foreach ($response->headers->getCookies() as $item) {

        $sResponse->cookie($item->getName(),$item->getValue(),$item->getExpiresTime(),$item->getPath(),
            $item->getDomain(),$item->isSecure(),$item->isHttpOnly());
    }
    $sResponse->status($response->getStatusCode());
    $sResponse->write($response->getContent());

    $kernel->terminate($request,$response);
});

$server->start();

进入public目录 执行php start.php即可运行。更多server设置属性查看swoole文档

整合好处 laravel 代码不用变
