hyperf nano 快速安装

通过 hyperf/nano 可以在无骨架、零配置的情况下快速搭建 Hyperf 应用。

安装

composer install hyperf/nano

快速开始

<?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();

启动：

php index.php start

简洁如此。

特性

• 无骨架
• 零配置
• 快速启动
• 闭包风格
• 支持注解外的全部 Hyperf 功能
• 兼容全部 Hyperf 组件
• Phar 友好

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 $app 管理的闭包回调中，$this 都被绑定到了 Hyperf\Nano\ContainerProxy 上。

中间件

<?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();

除了闭包之外，所有 $app->addXXX() 方法还接受类名作为参数。可以传入对应的 Hyperf 类。

异常处理

<?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();

命令行

<?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();

执行

php index.php echo

事件监听

<?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();

自定义进程

<?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();

定时任务

<?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 组件.

<?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();
