Rails ArgumentError：無効な％-encoding

URLが不正なので、先月、私たちのサイトで定期的にサイトを掻き集めてArgumentError: invalid %-encodingのエラーが発生しました。私はラックhereとhereとレールhereの問題の束を見て、this SO threadを見ましたが、決定的な解決策はないようです。 GETエラーの正しい解決策はありますか？私はラックをmonkeypatchする必要がありますか？Rails ArgumentError：無効な％-encoding

最新のラック版で修正される場合があります。 2年前にこの問題が発生したときにいくつかのバグ（[私がコメントしたものを含む]）（https://github.com/rack/rack/issues/225#issuecomment-2594611）が閉鎖されているようです。ボットをオプションでブロックしていますか？ –

悲しいことに、私は最新のラックにアップグレードしようとしましたが、まだ問題を見ていました（私は他の宝石を消さなければならなかったので、再度ダウングレードしました）。それは複数のIPアドレスから来ているので、それは巨根のゲームに変わっています、そして、私はもっと良い方法がなければならないことを望んでいます。 :) –

バックトレースを共有できますか？ –

あなたはこれらを検出し、正常に失敗するように設計さミドルウェアを注入できます。ここには、バックトレースです。基本的な考え方は、クエリ文字列を解析しようとすることです。失敗した場合は、HTTP 400で救済します。それ以外の場合は、リクエストを許可してください。

class RefuseInvalidRequest 
    def initialize(app) 
    @app = app 
    end 

    def call(env) 
    query = Rack::Utils.parse_nested_query(env['QUERY_STRING'].to_s) rescue :bad_query 
    if query == :bad_query 
     [400, {'Content-Type' => 'text/plain'}, "Bad Request"] 
    else 
     @app.call(env) 
    end 
    end 
end

私はこれをテストしていませんが、そのコンセプトは有効です。

私の開発環境では動作しません。私は理由を知っていませんが、それは 'のみを示す！無効なリクエスト "をログに記録します。 '' def initialize''に '' puts''を追加しようとしましたが、ログに '' called''が出力されません。ただ '!!無効なリクエスト 'です。はい、私はあなたのapplication.rbに 'config.middleware.use（" RefuseInvalidRequest "）'をしました。なぜこれが起こるか考えてみてください。 – Yana

ミドルウェアスタックに十分なミドルウェアを注入していない可能性があります。 –

'config.middleware.insert_before Rack :: Runtime、" RefuseInvalidRequest "。私が挿入できる最高のもの。実際には 'Rack :: MiniProfiler'と' Honeybadger'です。しかし、私はそれの前に挿入することはできません。それでも同じ出力。私の古い質問をログでチェックアウトhttp://stackoverflow.com/questions/21229499/custom-message-or-redirection-for-400-bad-request-because-of-unexcaped-on-par – Yana

あなたは、この内容で（たとえばrack.rb用）config/initializersファイルで作成monkeypatchingラックに対して気にしない場合：

module Rack 
    module Utils 
    if defined?(::Encoding) 
     def unescape(s, encoding = Encoding::UTF_8) 
     begin 
      URI.decode_www_form_component(s, encoding) 
     rescue ArgumentError 
      URI.decode_www_form_component(URI.encode(s), encoding) 
     end 
     end 
    else 
     def unescape(s, encoding = nil) 
     begin 
      URI.decode_www_form_component(s, encoding) 
     rescue ArgumentError 
      URI.decode_www_form_component(URI.encode(s), encoding) 
     end 
     end 
    end 
    module_function :unescape 
    end 
end

P.S.それは乗客と一緒に働いていますが、WebrickとThinではそうではありません。 webrickとthinの両方がリクエストを解析するように見えるので、イニシャライザがロードされる前にエラーが発生します。たとえば、薄いエラーの場合は、thin-1.6.2/lib/thin/request.rb:84で発生します。
