Rails 2.3.9查询参数的编码 [英] Rails 2.3.9 Encoding of Query Parameters

问题描述

如果我有类似于/ foo的内容吗？param =£

是否可以通过rails来将查询参数解码为utf8。

我尝试访问控制器中的参数，参数编码为ASCII-8BIT。这导致许多事情中断，因为我们很多其他的字符串被编码为UTF-8，而ruby不喜欢混合编码。

  params [：param] .encoding == Encoding.find（ASCII-8BIT）
  

解决方案

感谢Jason对此的磨练！

如果您使用Rails 2.3.x系列，则需要创建一个名为config / initializers / utf8_params.rb的文件，其中包含以下内容以解决该问题。

  raise检查这是否仍然需要+ Rails.version除非Rails.version =='2.3.10'
 
 class ActionController :: Base 
 
 def force_utf8_params 
 traverse = lambda do | object，block | 
 if object.kind_of？（Hash）
 object.each_value {| o | traverse.call（o，block）} 
 elsif object.kind_of？（Array）
 object.each {| o | traverse.call（o，block）} 
 else 
 block.call（object）
 end 
 object 
 end 
 force_encoding = lambda do | o | 
 o.force_encoding（Encoding :: UTF_8）if o.respond_to？（：force_encoding）
 end 
 traverse.call（params，force_encoding）
 end 
 before_filter： force_utf8_params 
 
 end 
  

请务必查看文章中的其他提示特别是在视图中的魔法评论周围。再次感谢Jason。

Is it possible to get rails to decode query parameters to utf8.

If i have something like /foo?param=£

And I try to access the parameter in my controller the parameter is encoded as ASCII-8BIT. This causes lots of things to break because a lot of our other strings are encoded UTF-8 and ruby doesn't like mixing encodings.

params[:param].encoding == Encoding.find("ASCII-8BIT")

Thanks a mill to Jason Weathered for this!

If you are on the Rails 2.3.x series, you need to create a file called config/initializers/utf8_params.rb with following content to fix the problem

raise "Check if this is still needed on " + Rails.version unless Rails.version == '2.3.10'

class ActionController::Base

  def force_utf8_params
    traverse = lambda do |object, block|
      if object.kind_of?(Hash)
        object.each_value { |o| traverse.call(o, block) }
      elsif object.kind_of?(Array)
        object.each { |o| traverse.call(o, block) }
      else
        block.call(object)
      end
      object
    end
    force_encoding = lambda do |o|
      o.force_encoding(Encoding::UTF_8) if o.respond_to?(:force_encoding)
    end
    traverse.call(params, force_encoding)
  end
  before_filter :force_utf8_params

end
