透過 hyperf/nano
可以在無骨架、零配置的情況下快速搭建 Hyperf 應用。
安裝
composer install hyperf/nano
快速開始
<?php
// index.php
use Hyperf\Nano\Factory\AppFactory;
require_once __DIR__ . '/vendor/autoload.php';
$app = AppFactory::create('0.0.0.0', 9051);
$app->get('/', function () {
$user = $this->request->input('user', 'nano');
$method = $this->request->getMethod();
return [
'message' => "hello {$user}",
'method' => $method,
];
});
$app->run();
啟動:
php index.php start
簡潔如此。
特性
- 無骨架
- 零配置
- 快速啟動
- 閉包風格
- 支援註解外的全部 Hyperf 功能
- 相容全部 Hyperf 元件
- Phar 友好
更多示例
路由
$app 集成了 Hyperf 路由器的所有方法。
<?php
use Hyperf\Nano\Factory\AppFactory;
require_once __DIR__ . '/vendor/autoload.php';
$app = AppFactory::create();
$app->addGroup('/nano', function () use ($app) {
$app->addRoute(['GET', 'POST'], '/{id:\d+}', function($id) {
return '/nano/'.$id;
});
$app->put('/{name:.+}', function($name) {
return '/nano/'.$name;
});
});
$app->run();
DI 容器
<?php
use Hyperf\Nano\ContainerProxy;
use Hyperf\Nano\Factory\AppFactory;
require_once __DIR__ . '/vendor/autoload.php';
class Foo {
public function bar() {
return 'bar';
}
}
$app = AppFactory::create();
$app->getContainer()->set(Foo::class, new Foo());
$app->get('/', function () {
/** @var ContainerProxy $this */
$foo = $this->get(Foo::class);
return $foo->bar();
});
$app->run();
所有 $app 管理的閉包回撥中,$this 都被繫結到了
Hyperf\Nano\ContainerProxy
上。
中介軟體
<?php
use Hyperf\Nano\Factory\AppFactory;
require_once __DIR__ . '/vendor/autoload.php';
$app = AppFactory::create();
$app->get('/', function () {
return $this->request->getAttribute('key');
});
$app->addMiddleware(function ($request, $handler) {
$request = $request->withAttribute('key', 'value');
return $handler->handle($request);
});
$app->run();
除了閉包之外,所有 $app->addXXX() 方法還接受類名作為引數。可以傳入對應的 Hyperf 類。
異常處理
<?php
use Hyperf\HttpMessage\Stream\SwooleStream;
use Hyperf\Nano\Factory\AppFactory;
require_once __DIR__ . '/vendor/autoload.php';
$app = AppFactory::create();
$app->get('/', function () {
throw new \Exception();
});
$app->addExceptionHandler(function ($throwable, $response) {
return $response->withStatus('418')
->withBody(new SwooleStream('I\'m a teapot'));
});
$app->run();
命令列
<?php
use Hyperf\Contract\StdoutLoggerInterface;
use Hyperf\Nano\Factory\AppFactory;
require_once __DIR__ . '/vendor/autoload.php';
$app = AppFactory::create();
$app->addCommand('echo', function(){
$this->get(StdoutLoggerInterface::class)->info('A new command called echo!');
});
$app->run();
執行
php index.php echo
事件監聽
<?php
use Hyperf\Contract\StdoutLoggerInterface;
use Hyperf\Framework\Event\BootApplication;
use Hyperf\Nano\Factory\AppFactory;
require_once __DIR__ . '/vendor/autoload.php';
$app = AppFactory::create();
$app->addListener(BootApplication::class, function($event){
$this->get(StdoutLoggerInterface::class)->info('App started');
});
$app->run();
自定義程序
<?php
use Hyperf\Contract\StdoutLoggerInterface;
use Hyperf\Nano\Factory\AppFactory;
require_once __DIR__ . '/vendor/autoload.php';
$app = AppFactory::create();
$app->addProcess(function(){
while (true) {
sleep(1);
$this->get(StdoutLoggerInterface::class)->info('Processing...');
}
});
$app->run();
定時任務
<?php
use Hyperf\Contract\StdoutLoggerInterface;
use Hyperf\Nano\Factory\AppFactory;
require_once __DIR__ . '/vendor/autoload.php';
$app = AppFactory::create();
$app->addCrontab('* * * * * *', function(){
$this->get(StdoutLoggerInterface::class)->info('execute every second!');
});
$app->run();
使用 Hyperf 元件.
<?php
use Hyperf\DB\DB;
use Hyperf\Nano\Factory\AppFactory;
require_once __DIR__ . '/vendor/autoload.php';
$app = AppFactory::create();
$app->config([
'db.default' => [
'host' => env('DB_HOST', 'localhost'),
'port' => env('DB_PORT', 3306),
'database' => env('DB_DATABASE', 'hyperf'),
'username' => env('DB_USERNAME', 'root'),
'password' => env('DB_PASSWORD', ''),
]
]);
$app->get('/', function(){
return DB::query('SELECT * FROM `user` WHERE gender = ?;', [1]);
});
$app->run();
