初探Swoole--Swooleでhello world

を起動

メモリの使い勝手--PHPやっとvs JAVAとか

初級アプリケーション--ユーザー登録を実現[作成中]

展望--Swooleの限界分析と私個人の期待[執筆中]

レビュー
前節のメモリの妙用--PHPはやっとvs JAVAになることができて、私達はSwooleのMYSQLデータベースCURDの操作を理解して、この節はMongoDBでデモをします.
やる
環境の説明:

MacOS X El Captain 10.11.6

PHP 7.0.8 with MongoDB support

MongoDB 1.1.8

CSSフレームワークBootstrap 3

まず、ユーザー登録ページ/tpl/login.htmlを作成します.

    
        
    
    
        

            
Login
            Username: 

            Password: 

            Submit
        
    

PHPコード
MongoDBを導入しました

selectDatabase($dbname);
            self::$dbname = $dbname;
        }
        return self::$db;
    }

    public static function id($id){
        return new MongoDB\BSON\ObjectID($id);
    }

    public function __call($name, $arguments){
        return self::$db->selectCollection(self::$dbname, $name);
    }
}

Swoole起動コード

_GLOBAL_SESSION = [];
$http->mongo      = Mongo::instance('db');
$http->db         = new \stdClass();

#      ,             .        /  IO
if('user'){
    echo "      
";
    $http->db->user = [];
    $users = $http->mongo->user->find([]);
    foreach ($users as $i => $user) {
        $user['_id'] = $user['_id']->__toString();
        $http->db->user[$user['username']] = $user;
    }
    echo "        

";
    unset($user);unset($users);
}

プライマリロジック:

on('request', function(swoole_http_request $req, swoole_http_response $res) use($http) {


    if (!isset($req->cookie) || !isset($req->cookie['sid']) || !$req->cookie['sid']) {
        $req->cookie['sid'] = md5(password_hash(time().mt_rand(100000, 999999), 1));
        $res->cookie('sid', $req->cookie['sid'], time() + 60 * 60 * 24 * 365 * 10, '/', '', false, true);
    }

    $_SESS_ID = $req->cookie['sid'];
    if (!is_array($http->_GLOBAL_SESSION[ $_SESS_ID ])) $http->_GLOBAL_SESSION[ $_SESS_ID ] = [];
    $_SESSION = &$http->_GLOBAL_SESSION[ $_SESS_ID ];

    if ( $req->server['request_uri'] == '/' ) {
        $res->status(302);
        $res->header('Location', '/login/');
        $res->end();
        return;
    }else
    if ( $req->server['request_uri'] == '/login/' ) {
        if ($_SESSION['user']) {
            $res->status(302);
            $res->header('Location', '/i/');
            $res->end();
            return;
        }

        $html = file_get_contents(dirname(__FILE__).'/tpl/'.'login.html');
        $res->write($html);
        $res->end();

        unset($html);
        return;
    }else
    if ( $req->server['request_uri'] == '/dologin/' ) {
        $user = $http->db->user[$req->post['username']];
        if (!$user || !password_verify($req->post['password'], $user['password'])) {
            $res->write('bad_account_or_password');
            $res->end();
            return;
        }
        $_SESSION['user']           = $user;
        unset($user);

        $res->status(302);
        $res->header('Location', '/vul/');
        $res->end();
        return;
    }else
    if ( $req->server['request_uri'] == '/i/' ) {
        $res->write('You currently logged in as'.$_SESSION['user']['username']);
        $res->end();
        return;
    }

    $res->status(404);
    $res->end();
    return;
});
