私はチュートリアルをしていますが、ログイン領域に詰まっています。私がPassport.jsでログインしているときは、常に "failureRedirect"を認証で実行します。私は問題はボディパーサーに関連することができることを考えていくつかのフォーラムで読んだ後Passport.jsを使用しているログインシステムは常に "failureRedirect"（nodejs）を実行しています
Error: null User: false Info: {"message":"Missing credentials"}
：私は次のメッセージを受け取ったrouter.post（「ログイン」）ルートを交換デバッグしようとした後
。私は問題を解決しようとしてきましたが、私はまだできませんでした。私は経験豊富なnode.jsプログラマーの助けに感謝します。

私はROUTEでデバッグするために使用されるコードは router.post（ '/ログイン'、passport.authenticate（ 'ローカル'、機能（errは、ユーザー、情報）{ はconsole.log（ "認証をusers.js 「）; にconsole.log（ERR）; にconsole.log（ユーザ）; にconsole.log（情報）; }）、関数（REQ、RES）{ はconsole.log（ '認証成功'）; req.flash（ 'success'、 'あなたはログインしています'）; res.redirect（ '/'）; }）; – Rafa
