轨道omniauth和UTF-8错误 [英] rails omniauth and UTF-8 errors

问题描述

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

 omniauth=> 
 {user_info=> 
 {name=>JoeMcÙisnean，
last_name=>McÙisnean，
first_name=>Joe，
email =>[e-mail]}，
uid=> 
https://www.google.com/accounts/o8/id?id=AItOawnQmfdfsdfsdfdsfsdhGWmuLTiX2Id40k，
provider=>google_apps} 
  

在我的用户模型中

  def apply_omniauth omn​​iauth）
 #add关于用户的一些信息
 self.email = omniauth ['user_info'] ['email']如果email.blank？ 
 self.name = omniauth ['user_info'] ['name']如果name.blank？ 
 self.name = omniauth ['user_info'] [：name] if name.blank？ 
 self.nickname = omniauth ['user_info'] ['nickname'] if nickname.blank？ 
 self.nickname = name.gsub（''，''）。如果昵称是
 
除非omniauth ['credentials']。空白？ 
 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 
  

$ b $我不太熟悉UTF编码，所以我不知道我应该在哪里指定编码？但是我猜这是在它被放入用户模型并创建之前，我不确定该怎么做？

更新：

Rails 3.0.10
Omniauth 0.2.6
Ruby 1.9.2
PG 0.11.0

默认编码是UTF-8

似乎没有这样做，所以我进一步挖掘，发现这个视图：

 显示/Users/holden/Code/someapp/app/views/users/registrations/_signup.html.erb第5行提高的位置：
 
不兼容的字符编码：ASCII-8BIT和UTF-8 
提取源（绕行＃5）：
 
 2：<％= f.error_messages％> 
 3：
 4：<％= f.input：name，：hint => '你的真名'％> 
 5：<％= f.input：昵称，：hint => '您选择的用户名'％> 
 6：
 7：<％除非@ user.errors [：email] .present？或@ user.email％> 
 8：<％= f.input：email，：as => ：hidden％> 
  

更新更新：

作为返回ASCII-8BIT字符的omniauth宝石，所以我的下一个问题是如何解析散列并将其转换回UTF8，以便我的应用程序不会爆炸？

session [：omniauth] = omniauth.to_utf8

这个疯狂骑行的另一部分是当我输入这进入控制台

  d = {user_info=> {email=>[e-mail] ，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=>[e-mail]，first_name="Joe，last_name=>McÙisnean，name=& McÙisnean}} 
  

如果有的话，这是一个痛苦的噩梦。

解决方案

Omniauth被证明是产生ASCII-8BIT的问题

我最终强迫Omniauth哈希转换为提交使用：

omniauth_controller.rb

  session [ ：omniauth] = omniauth.to_utf8 
  

添加递归方法强制将流氓ASCII-8BIT转换为UTF8

some_initializer.rb

  class Hash 
 def to_utf8 
哈希[
 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tadman

将包含非UTF字符的哈希递归转换为UTF

I had a recent error using omniauth trying to populate some fields from Google's login

Encoding::CompatibilityError: incompatible character encodings: ASCII-8BIT and UTF-8

"omniauth"=>
  {"user_info"=>
    {"name"=>"Joe McÙisnean",
     "last_name"=>"McÙisnean",
     "first_name"=>"Joe",
     "email"=>"[e-mail]"},
   "uid"=>
    "https://www.google.com/accounts/o8/id?id=AItOawnQmfdfsdfsdfdsfsdhGWmuLTiX2Id40k",
   "provider"=>"google_apps"}

In my user model

  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

I'm not hugely knowledgeable about UTF encoding, so I'm not sure where I should be specifying the encoding? But I'm guessing it's here before it get's put into the user model and created, I'm unsure what to do about it?

UPDATE:

Rails 3.0.10 Omniauth 0.2.6 Ruby 1.9.2 PG 0.11.0

Default encoding is UTF-8

That didn't seem to be it, so I dug further and found this in the view:

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 %>

UPDATE UPDATE:

It seems to be the omniauth gem which is returns the ASCII-8BIT chars, so my next question is how can I parse the hash and convert it back into UTF8 so my app doesn't explode?

session[:omniauth] = omniauth.to_utf8

Another part to this crazy ride is when I type this into the console

d={"user_info"=>{"email"=>"[e-mail]", "first_name"=>"Joe", "last_name"=>"Mc\xC3\x99isnean", "name"=>"Joe Mc\xC3\x99isnean"}}

It automatically converts it to UTF-8, but it explodes when shoved into a session

 => {"user_info"=>{"email"=>"[e-mail]", "first_name"=>"Joe", "last_name"=>"McÙisnean", "name"=>"Joe McÙisnean"}} 

This is a painful nightmare if there ever was one.

解决方案

Omniauth proved to be the problem producing the ASCII-8BIT

I ended up forcing the Omniauth hash into submission using:

omniauth_controller.rb

session[:omniauth] = omniauth.to_utf8

added recursive method to force convert the rogue ASCII-8BIT to UTF8

some_initializer.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

Special thanks to tadman

recursively convert hash containing non-UTF chars to UTF
