使用composer搭建slim framework mvc demo

使用composer dump-autoload生成autoload文件,自动加载编写的models和controllers.达到MVC分层的目的。当然使用spl_autoload也可以实现自动加载类，但是本人的服务器环境中,使用spl_autoload命名空间会失效…

安装slim 和 twig-view 以及 Eloquent:fa-hand-o-down:

使用composer autoload 加载自己的 文件

https://getcomposer.org/doc/03-cli.md#dump-autoload

运行如下命令php composer.phar dump-autoload windows环境直接composer dump-autoload
下面是我自己新建的目录结构

index.php 文件

<?php
require '../vendor/autoload.php';

$app = new Slim\App(
    new \Slim\Container(
        include '../core/container.config.php'
    )
);

$app->get('/','Core\Controller\Test');
// Render Twig template in route
$app->get('/hello/{name}', function ($request, $response, $args) {
    return $this->view->render($response, 'profile.html', [
        'name' => $args['name']
    ]);
})->setName('profile');

$app->run();

container.config.php

<?php
return [
    'settings' => [
        'viewTemplatesDirectory' => '../core/views',
        'compilation_cache'=>'../core/caches',
        'determineRouteBeforeAppMiddleware' => false,
        'displayErrorDetails' => true,
        'db' => [
            'driver' => 'mysql',
            'host' => 'localhost',
            'database' => 'note',
            'username' => 'root',
            'password' => '',
            'charset'   => 'utf8',
            'collation' => 'utf8_unicode_ci',
            'prefix'    => '',
        ]
    ],
    'view' => function ($c) {
    	$view = new \Slim\Views\Twig($c['settings']['viewTemplatesDirectory'], [
        	'cache' => $c['settings']['compilation_cache'],
        	//'cache' => false,
    	]);
    	$view->addExtension(new \Slim\Views\TwigExtension(
        	$c['router'],
        	$c['request']->getUri()
    	));
        return $view;
    },
    'db'=>function($c){
    	$capsule = new \Illuminate\Database\Capsule\Manager;
    	$capsule->addConnection($c['settings']['db']);

    	$capsule->setAsGlobal();
    	$capsule->bootEloquent();

    	return $capsule;
    },

];

Test

<?php
namespace Core\Controller;

class Test{
	private $view;
    private $db;

	function __construct($ci){		
		$this->view=$ci['view'];
		$this->db=$ci['db'];
	}

	public function __invoke($request,$response,$args)
    {
        $table=$this->db->table('note');
        $notes=$table->get();
        return $this->view->render($response,'notes.html',['notes'=>$notes]);
    }
}

模板文件省略。。。
