Ruby 2和Rails 4編碼問題

Question

我正在做一個從Rails 3.2和ruby 1.9.x遷移到ruby 2.2.x和rails 4.2.4版本的項目。

當項目進入生產服務器時，它開始引發如下編碼錯誤：

"\\xC3" from ASCII-8BIT to UTF-8

然后是如下的堆棧跟蹤：

["/var/www/suba/vendor/bundle/ruby/2.2.0/gems/activesupport-4.2.4/lib/active_support/core_ext/object/json.rb:34:in `encode'"
 "/var/www/suba/vendor/bundle/ruby/2.2.0/gems/activesupport-4.2.4/lib/active_support/core_ext/object/json.rb:34:in `to_json'"
 "/var/www/suba/vendor/bundle/ruby/2.2.0/gems/activesupport-4.2.4/lib/active_support/core_ext/object/json.rb:34:in `to_json_with_active_support_encoder'"
 "/var/www/suba/vendor/bundle/ruby/2.2.0/gems/activesupport-4.2.4/lib/active_support/json/encoding.rb:57:in `to_json'"
 "/var/www/suba/vendor/bundle/ruby/2.2.0/gems/json-1.8.3/lib/json/common.rb:223:in `generate'"
 "/var/www/suba/vendor/bundle/ruby/2.2.0/gems/json-1.8.3/lib/json/common.rb:223:in `generate'"
 "/var/www/suba/vendor/bundle/ruby/2.2.0/gems/activesupport-4.2.4/lib/active_support/json/encoding.rb:101:in `stringify'"
 "/var/www/suba/vendor/bundle/ruby/2.2.0/gems/activesupport-4.2.4/lib/active_support/json/encoding.rb:35:in `encode'"
 "/var/www/suba/vendor/bundle/ruby/2.2.0/gems/activesupport-4.2.4/lib/active_support/json/encoding.rb:22:in `encode'"
 "/var/www/suba/vendor/bundle/ruby/2.2.0/gems/activesupport-4.2.4/lib/active_support/core_ext/object/json.rb:37:in `to_json_with_active_support_encoder'"
 "/var/www/suba/vendor/bundle/ruby/2.2.0/gems/multi_json-1.11.2/lib/multi_json/adapters/json_common.rb:19:in `dump'"
 "/var/www/suba/vendor/bundle/ruby/2.2.0/gems/multi_json-1.11.2/lib/multi_json/adapter.rb:25:in `dump'"
 "/var/www/suba/vendor/bundle/ruby/2.2.0/gems/multi_json-1.11.2/lib/multi_json.rb:136:in `dump'"
 "/var/www/suba/vendor/bundle/ruby/2.2.0/gems/resque-1.24.1/lib/resque/helpers.rb:25:in `encode'"
 "/var/www/suba/vendor/bundle/ruby/2.2.0/gems/resque-1.24.1/lib/resque.rb:173:in `push'"
 "/var/www/suba/vendor/bundle/ruby/2.2.0/gems/resque-1.24.1/lib/resque/job.rb:51:in `create'"
 "/var/www/suba/vendor/bundle/ruby/2.2.0/gems/resque-1.24.1/lib/resque.rb:271:in `enqueue_to'"
 "/var/www/suba/vendor/bundle/ruby/2.2.0/gems/resque-1.24.1/lib/resque.rb:252:in `enqueue'"
 "/var/www/suba/app/controllers/call_center/chat_controller.rb:6:in `transcript'"

和transcript方法上的chat_controller.rb第6行：

  def transcript
    Resque.enqueue(Chat::SessionTranscript, read_request_body)
    head :ok
  end

  def read_request_body
    xml = request.body.read
    Rails.logger.info("XML: #{xml}")
    xml
  end

在代碼庫的另一點，我們使用如下代碼解決了此問題：

string.encode("UTF-8", :invalid => :replace, :undef => :replace, :replace => "?")

但是相同的錯誤開始在其他部分出現。

有沒有人通過這個，您如何處理？

在此先感謝您。

Answer 1

我通過替換為34來解決了這個問題

（...）/的ActiveSupport-4.2.4 / LIB / active_support / core_ext /對象/ json.rb

對於：

self.force_encoding('utf-8').to_json_without_active_support_encoder(options)
