cakephp3でのauth認証

ちょっといじってあります

サンプルソースの通りにやってもうまく動かなかったのでいくつか修正しています

前提

  • usersテーブルを使用
  • SimplePasswordHasher使用

準備

usersテーブルを作成
CREATE TABLE users (
    id INT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    username VARCHAR(50),
    password VARCHAR(100),
    role VARCHAR(20),
    created DATETIME DEFAULT NULL,
    modified DATETIME DEFAULT NULL
);
bakeでコントローラー、モデル、ビューを作成
sh app/App/Console/cake bake model Users
sh app/App/Console/cake bake controller Users
sh app/App/Console/cake bake view Users

実装

app/App/Controller/UsersController.php
<?php
namespace App\Controller;

        // 上位クラスの機能を使用
        parent::beforeFilter($event);
        // ユーザーによる登録とログアウトを許可する
        $this->Auth->allow('add', 'logout');

    }

実行イメージ

ユーザー情報を設定して登録

f:id:m_shige1979:20140614231055p:plain

登録成功後に一覧を表示

f:id:m_shige1979:20140614231107p:plain

ユーザーとパスワードを設定して認証する

f:id:m_shige1979:20140614231116p:plain

ログイン後

f:id:m_shige1979:20140614231123p:plain

まとめ

基本的なログイン方法は理解できた。モデルやセッション、scopeなどを変更して確認してみる。
他のパスワードハッシュ関数もチェックしてみよう

パスワードハッシュについて

Simpleの場合はphpでのパスワードハッシュ関数を使っている感じ…
平文が同じでも結果が異なるのでデータからは平文を予測できないので以前のようなsha1md5よりは安全な感じがする
