rails omniauth和UTF-8错误

Question

我最近使用omniauth尝试从Google的登录信息填充某些字段时出错

Encoding :: CompatibilityError:不兼容的字符编码:ASCII-8BIT和UTF-8

"omniauth"=>
  {"user_info"=>
    {"name"=>"Joe McÙisnean",
     "last_name"=>"McÙisnean",
     "first_name"=>"Joe",
     "email"=>"someemail@gmail.com"},
   "uid"=>
    "https://www.google.com/accounts/o8/id?id=AItOawnQmfdfsdfsdfdsfsdhGWmuLTiX2Id40k",
   "provider"=>"google_apps"}

在我的用户模型中

  def apply_omniauth(omniauth)
    #add some info about the user
    self.email = omniauth['user_info']['email'] if email.blank?
    self.name = omniauth['user_info']['name'] if name.blank?
    self.name = omniauth['user_info'][:name] if name.blank?
    self.nickname = omniauth['user_info']['nickname'] if nickname.blank?
    self.nickname = name.gsub(' ','').downcase if nickname.blank?

    unless omniauth['credentials'].blank?
      user_tokens.build(:provider => omniauth['provider'], 
                        :uid => omniauth['uid'],
                        :token => omniauth['credentials']['token'], 
                        :secret => omniauth['credentials']['secret'])
    else
      user_tokens.build(:provider => omniauth['provider'], :uid => omniauth['uid'])
    end
  end

我对UTF编码知之甚少,所以我不确定在哪里指定编码？但是我猜它是在它被放入用户模型并创建之前,我不确定该怎么办呢？

更新:

Rails 3.0.10 Omniauth 0.2.6 Ruby 1.9.2 PG 0.11.0

默认编码为UTF-8

这似乎不是它,所以我进一步挖掘并在视图中找到了这个:

Showing /Users/holden/Code/someapp/app/views/users/registrations/_signup.html.erb where line #5 raised:

incompatible character encodings: ASCII-8BIT and UTF-8
Extracted source (around line #5):

2:   <%= f.error_messages %>
3: 
4:   <%= f.input :name, :hint => 'your real name' %>
5:   <%= f.input :nickname, :hint => 'Username of your choosing' %>
6: 
7:   <% unless @user.errors[:email].present? or @user.email %>
8:     <%= f.input :email, :as => :hidden %>

更新更新:

它似乎是omniauth gem返回ASCII-8BIT字符,所以我的下一个问题是如何解析哈希并将其转换回UTF8,以便我的应用程序不会爆炸？

session[:omniauth] = omniauth.to_utf8

这次疯狂骑行的另一部分是当我在控制台中键入它时

d={"user_info"=>{"email"=>"someemail@gmail.com", "first_name"=>"Joe", "last_name"=>"Mc\xC3\x99isnean", "name"=>"Joe Mc\xC3\x99isnean"}}

它会自动将其转换为UTF-8,但在推入会话时会爆炸

 => {"user_info"=>{"email"=>"someemail@gmail.com", "first_name"=>"Joe", "last_name"=>"McÙisnean", "name"=>"Joe McÙisnean"}} 

如果有的话,这是一场痛苦的噩梦.

Answer 1

Omniauth 被证明是产生 ASCII-8BIT 的问题

我最终使用以下命令强制提交 Omniauth 哈希：

omn​​iauth_controller.rb

session[:omniauth] = omniauth.to_utf8

添加了递归方法来强制将流氓 ASCII-8BIT 转换为 UTF8

一些_初始化程序.rb

class Hash
  def to_utf8
    Hash[
      self.collect do |k, v|
        if (v.respond_to?(:to_utf8))
          [ k, v.to_utf8 ]
        elsif (v.respond_to?(:encoding))
          [ k, v.dup.force_encode('UTF-8') ]
        else
          [ k, v ]
        end
      end
    ]
  end
end

特别感谢塔德曼

递归地将包含非 UTF 字符的哈希转换为 UTF
