```
require_once 'vendor/autoload.php';
use \Psr\Http\Message\ServerRequestInterface as Request;
use \Psr\Http\Message\ResponseInterface as Response;
//创建 db
$config['displayErrorDetails'] = true;
$config['addContentLengthHeader'] = false;
$config['db']['host'] = 'localhost';
$config['db']['user'] = 'user';
$config['db']['pass'] = 'password';
$config['db']['dbname'] = 'exampleapp';
$app = new \Slim\App(['settings' => $config]);
/*创建一个容器*/
$container = $app->getContainer();
/* 添加日志数据库 */
$container['logger'] = function($c) {
$logger = new \Monolog\Logger('my_logger');
$file_handler = new \Monolog\Handler\StreamHandler('../logs/app.log');
$logger->pushHandler($file_handler);
return $logger;
};
$this->logger->addInfo('Something interesting happened');
/* 添加 mysql 数据库 */
$container['db'] = function ($c) {
$db = $c['settings']['db'];
$pdo = new PDO('mysql:host=' . $db['host'] . ';dbname=' . $db['dbname'],
$db['user'], $db['pass']);
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$pdo->setAttribute(PDO::ATTR_DEFAULT_FETCH_MODE, PDO::FETCH_ASSOC);
return $pdo;
};
$app->get('/hello/{name}', function (Request $request, Response $response, array $args) {
$name = $args['name'];
$response->getBody()->write("Hello, $name");
return $response;
});
$app->run();
```
配置 `composer.json`,使其自动加载自定义的类
```
{
"require": {
"slim/slim": "^3.1",
"slim/php-view": "^2.0",
"monolog/monolog": "^1.17",
"robmorgan/phinx": "^0.5.1"
},
"autoload": {
"psr-4": {
"Example\\": "classes/"
}
}
}
```
运行
`php -S localhost:8080
`
