不用三方包 给 Laravel 开启 Swoole
Swoole 是一款优秀的 PHP 扩展,利用其可以实现原生 PHP 很难做到的常驻服务和异步。正好我有个 Laravel 项目可以折腾,就研究了下。
Laravel 项目是基于 composer 的,所以我先帖下我的 composer.json
中的 require 声明:
{ "require": { "php": "^7.1.3", "cybercog/laravel-love": "^5.1", "dingo/api": "~v2.0.0-alpha2", "doctrine/dbal": "^2.8", "fideloper/proxy": "^4.0", "guzzlehttp/guzzle": "^6.3", "infyomlabs/adminlte-templates": "5.6.x-dev", "infyomlabs/laravel-generator": "5.6.x-dev", "jeroennoten/laravel-adminlte": "^1.23", "laravel/framework": "5.6.*", "laravel/tinker": "^1.0", "laravelcollective/html": "^5.6.0", "lshorz/luocaptcha": "^1.0", "overtrue/laravel-lang": "v3.0.08", "overtrue/laravel-wechat": "^4.0", "predis/predis": "^1.1", "spatie/laravel-permission": "^2.17", "tymon/jwt-auth": "~1.0.0-rc.2", "yajra/laravel-datatables-buttons": "^4.0", "yajra/laravel-datatables-oracle": "^8.7" } }
如果我们要开启 swoole,我们可选的包有这些:
但一般来说,项目中需要常驻容器的服务与每次均需重新构建的服务并不一样,所以我才剑走偏锋。
起步
我们需要将 public/index.php
替换成如下
<?php use Illuminate\Http\Request; use Illuminate\Http\Response; define('LARAVEL_START', microtime(true)); require __DIR__ . '/../vendor/autoload.php'; $app = require_once __DIR__ . '/../bootstrap/app.php'; class Laravel { /** * Illuminate\Foundation\Application * * @var \Illuminate\Foundation\Application */ public $app; /** * App\Http\Kernel * * @var \App\Http\Kernel */ public $kernel; /** * App\Http\Requests\Request * * @var \App\Http\Requests\Request */ public $request; /** * Illuminate\Http\JsonResponse * * @var \Illuminate\Http\JsonResponse */ public $response; /** * 构造 * * @param \Illuminate\Foundation\Application $app */ public function __construct(\Illuminate\Foundation\Application $app) { $this->app = $app; } /** * RUN * * @return void */ public function run() { \Swoole\Runtime::enableCoroutine(true); $http = new swoole_http_server('127.0.0.1', '80'); $http->set([ 'document_root' => public_path('/'), 'enable_static_handler' => true, ]); $http->on('request', function ($req, $res) { try { $kernel = $this->app->make(Illuminate\Contracts\Http\Kernel::class); $get = $req->get ?? []; $post = $req->post ?? []; $input = array_merge($get, $post); $cookie = $req->cookie ?? []; $files = $req->files ?? []; $server = $req->server ?? []; $request = Request::create($req->server['request_uri'], $req->server['request_method'], $input, $cookie, $files, $server); if (isset($req->header['x-requested-with']) && $req->header['x-requested-with'] == "XMLHttpRequest") { $request->headers->set('X-Requested-With', "XMLHttpRequest", true); } if (isset($req->header['accept']) && $req->header['accept']) { $request->headers->set('Accept', $req->header['accept'], true); } $response = $kernel->handle($request); $res->status($response->getStatusCode()); foreach ($response->headers->allPreserveCaseWithoutCookies() as $name => $values) { foreach ($values as $value) { $res->header($name, $value, false); } } foreach ($response->headers->getCookies() as $cookie) { $res->header('Set-Cookie', $cookie->getName() . strstr($cookie, '='), false); } dump(time()); $res->end($response->getContent()); $this->app->forgetInstance('request'); } catch (\throwable $e) { echo $e->getMessage(); echo PHP_EOL; echo $e->getFile(); echo PHP_EOL; echo $e->getLine(); echo PHP_EOL; } }); $http->start(); } } (new Laravel($app))->run();
运行时发现大多数页面均没有问题,只有几个用了 infyomlabs/laravel-generator
产生的列表页,AJAX 拉取 JSON 时却返回了 HTML。
排查
在有问题页面的 controller 代码中,找到如下
/** * Display a listing of the Star. * * @param StarDataTable $starDataTable * @return Response */ public function index(StarDataTable $starDataTable) { return $starDataTable->render('stars.index'); } 定位 StarDataTable::render() 到了 /** * Process dataTables needed render output. * * @param string $view * @param array $data * @param array $mergeData * @return mixed */ public function render($view, $data = [], $mergeData = []) { if ($this->request()->ajax() && $this->request()->wantsJson()) { return app()->call([$this, 'ajax']); } ... }
这是判断 $this->request()
是不是 XHR 请求,且 Accept
请求头声明了 application/json
而 $this->request()
实现如下
/** * Get DataTables Request instance. * * @return \Yajra\DataTables\Utilities\Request */ public function request() { return $this->request ?: $this->request = resolve('datatables.request'); }
不难看出,如果第一次构建,会走到
$this->request = resolve('datatables.request');
而 resolve 的实现是啥?
if (! function_exists('resolve')) { /** * Resolve a service from the container. * * @param string $name * @return mixed */ function resolve($name) { return app($name); } }
就是从容器中取出 datatables.request
的过程。
所以我们只需让每次请求结束,$app 容器忘掉 datatables.request
就好了
改进
增加遗忘 datatables.request
$res->end($response->getContent()); $this->app->forgetInstance('request'); $this->app->forgetInstance('datatables.request'); $this->app->forgetInstance(\Dingo\Api\Http\Middleware\Request::class);

测试
比原生 laravel 确实快不少(这还有 4 句 SQL 查询) 。
注,此处给出的代码可以借鉴,但未经长期验证。且不同项目实际用到的包不同,需要在调试过程中 debug
容器中的服务提供者,和追踪代码来调优。
已知问题
- flash 闪存数据以及表单验证错误的展示有问题
- PDO 会报 Cannot execute queries while other unbuffered queries are active symfony/symfony...
- Throttle 的 IP 获取设定默认会产生问题
