Ruby on Rails "UTF-8" geçersiz bayt sırası; nedeniyle bot

Bazı hatalar Çinli bir bot tarafından tetiklenen var: benim web sitelerinde gezinir http://www.easou.com/search/spider.html.

Benim uygulamalarının sürümleri Ruby 1.9.3 ile ve 3.2 Raylar.X

Burada bir stacktrace :

Gördüğünüz gibi geçersiz utf-8 rack.request.form_vars url de yok . Gün başına yaklaşık yüz hataları ve bu bir benzer yanı var.

Yani, rack.request.form_vars utf-8 zorlamak için böyle bir şey denedim:

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

  def call(env)
    if env["rack.request.form_vars"] 
      env["rack.request.form_vars"] = env["rack.request.form_vars"].force_encoding('UTF-8')
    end
    @app.call(env)
  end
end

application.rb benim derim :

config.middleware.use "RackFormVarsSanitizer"

Ben zaten hataları var, çünkü işe yaramıyor. Sorun rack.request.form_vars ayarlamak için nasıl bilmiyorum çünkü geliştirme modunda test edemem.

utf8-cleaner gem yükledim ama hiçbir şey giderir.

Birileri bunu düzeltmek için bir fikrin var mı? ya da gelişimini tetiklemek için?

CEVAP

13 Temmuz 2014, Pazar

Benim diğer yanıt açıklamalarda araya gerek yok yani, bu şimdi yapıyorum – 24 saat boyunca hiç hata görmedim, çok umut verici görünüyor:

Ekle Gemfile rack-utf8_sanitizer:

gem 'rack-utf8_sanitizer'

ve çalıştırın

bundle

app/middleware/handle_invalid_percent_encoding.rb 26 *koyun ve sınıfı HandleInvalidPercentEncoding ExceptionApp biraz da genel olduğu için) yeniden adlandırın.

config config/application.rb blok yapın:

require "#{Rails.root}/app/middleware/handle_invalid_percent_encoding.rb"


# NOTE: These must be in this order relative to each other.
# HandleInvalidPercentEncoding just raises for encoding errors it doesn't cover,
# so it must run after (= be inserted before) Rack::UTF8Sanitizer.
config.middleware.insert 0, HandleInvalidPercentEncoding
config.middleware.insert 0, Rack::UTF8Sanitizer  # from a gem

Dağıtmak. Bitti.

(app üzerinde çalıştığım proje, katman konumunu oluyor, ama muhtemelen lib tercih ederim. Her neyse. Ya da çalışması gerekir.)
