passport-ldapNode Express サーバーでLDAP 経由 (を使用) で実行するようにパスポートを構成しようとして、過去数日間にさまざまな問題について投稿しました。とにかく、 のauthenticate関数がnode_modules/passport/lib/passport/middleware/authenticate.js無限ループを実行しており、自分自身を何度も呼び出していることがわかりました。Node デバッガーを使用debuggerして、コードに一連のステートメントを入れたところ、正しいログイン資格情報を入力するたびに、それが繰り返されることがわかりました (login_fail間違った資格情報を入力すると、ページに正しくリダイレクトされます)。
コマンドラインでのデバッガーの表示は次のとおりです。

ご覧のとおり、同じ行を何度も繰り返しています (そして、入力contし続けていた場合)、サーバーがタイムアウトするまでこれを続けます。なぜこれが起こっているのですか？また、サーバーを最初に起動したときになぜそのエラーが発生するのかわかりません。それがループを引き起こしている可能性がありますか？私はそれを3、4回グーグルで検索しましたが、まだうまくいく解決策を見つけていません。
編集：私は問題を見つけたと思います。で定義されているように、コード プログラムはこのres.onステートメントを完全にスキップしnode_modules/passport-ldap/lib/passport-ldap/strategy.jsます。
