Nano 是一款零配置、无骨架、极小化的 Hyperf 发行版,通过 Nano 可以让您仅仅通过 1 个 PHP 文件即可快速搭建一个 Hyperf 应用。
Svelte
的作者提出过一个论断:“框架不是用来组织代码的,是用来组织思路的”。而 Nano 最突出的一个优点就是不打断你的思路。Nano 非常擅长于自我声明,几乎不需要了解框架细节,只需要简单读一读代码,就能知道代码的目的。通过极简的代码声明,完成一个完整的 Hyperf 应用。
composer require hyperf/nano
创建一个 PHP 文件,如 index.php 如下:
<?php
use Hyperf\Nano\Factory\AppFactory;
require_once __DIR__ . '/vendor/autoload.php';
$app = AppFactory::create();
$app->get('/', function () {
$user = $this->request->input('user', 'nano');
$method = $this->request->getMethod();
return [
'message' => "hello {$user}",
'method' => $method,
];
});
$app->run();
启动服务:
php index.php start
简洁如此。
$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();
<?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。
<?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。
<?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();
<?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
<?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();
<?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();
<?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();
<?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();
