LaravelのPHPで、かなりハマってしまった問題。

Laravelでソーシャルログインの認証拒否のテスト
Laravelでソーシャル認証を実装しました。
Laravelでソーシャル認証(Twitter, Facebook, Google)を実装してみた
Laravelでソーシャルログインを実装してみました。
Socialiteをインストールする
まず、Laravelにソーシャル認証用のプラグインSocialiteをインストールします。
Socialiteをインストールする方法...
LaravelのControllerでコールバック内では、以下の通りに実装しました。
|
1 2 3 4 5 |
try { $user = Socialite::driver('twitter')->user(); } catch (Exception $e) { return redirect("/"); } |
これで、Exceptionが発生してもcatchしてリダイレクトされるはずです。
早速実験してみます。
ソーシャルログイン時に以下の記事出てくる画面が表示された場合、Twitter、Facebook、Googleでログインを拒否したとします。
Twitter, Facebook, Googleでアプリケーションの連携を解除する
Twitter, Facebook, Googleといったユーザーのアカウントを使って、他のWEBサイトにログインする、いわゆるソーシャルログインが流行っていますね。
↓こんなやつです。
いちいち新しいアカウント...
すると、それぞれ次のエラーが発生します。
Twitterで拒否した場合
Twitterで拒否してみます。
・https://(url)/auth/login/callback/twitter?denied=xxxxx
InvalidArgumentException in TwitterProvider.php line 15:Invalid request. Missing OAuth verifier.

これ、全部、以下の関数の呼び出し元でExceptionが発生しています。
$user = Socialite::driver('twitter')->user();
ちゃんとTry～CatchでExceptionをCatchしているのに何で？？？？
PHPでネームスペース内で例外をキャッチするときは、グローバルスペースにエスケープしないとダメ
調べてみるとちゃんと書いてありました。
When catching an exception inside a namespace it is important that you escape to the global space:
私の不勉強で、PHPの仕様としては初歩的な考え方で、ミスっていました。
以下のようにしてしまうと、Exceptionでcatch出来るのは、同じネームスペース内のExceptionのみになってしまいます。
Socialite::driver内でのExceptionはcatch出来ません。
|
1 2 3 4 5 |
try { $user = Socialite::driver('twitter')->user(); } catch (Exception $e) { return redirect("/"); } |
Socialite::driver内のExceptionをcatchするには、以下のように、Exception ではなくて、バックスラッシュを付けてグローバルな名前空間であることを示して、\Exception をcatchする必要があります。
|
1 2 3 4 5 |
try { $user = Socialite::driver('twitter')->user(); } catch (\Exception $e) { return redirect("/"); } |
これでOKです。
まとめ
Exceptionのグローバルなnamespaceの考え方は、C#にもJavaにも存在しない概念のはずです。
私のようにJava、C#出身のPHPプログラマーは勘違いしてしまいます。
PHPの文法は以下の本で勉強し直します。
PHPとデータベース連携を学べる中級以上向けの本、おすすめ
PHPを学習していて基本的な文法をマスターした後にデータベース連携やユーザー認証、CRUD処理などをするのに適した本を探していて次の本を見つけました。
この種はWEBサイトよりもまとまった本が重宝します。
いずれもPHPのいわゆるフレーム...
どれか一冊という人には以下の「PHP+MySQLマスターブック」をおすすめします。
