假设我的电子邮件地址像putin crab@Пззззззззззззз1079

如何在rails 3.1中验证该地址

我的模型（我使用Mongoid）：

对于验证请求，我使用gem

在rails控制台中（普通电子邮件）：

ruby-1.9.2-p290:001>usr=User.new（：email=>）pretty@gmail.com" )
=> # 
ruby-1.9.2-p290:002>usr.valid？
=>正确

在rails控制台中（fu#ing email）：

ruby-1.9.2-p290:003>usr=User.new（：email=>“putin-crab@Пзззззззззззз
=> # 
ruby-1.9.2-p290:004>usr.valid？

regexp无法识别电子邮件，因为它们不是有效的电子邮件

在Ruby（和Rails）中验证电子邮件地址有几种好方法，每种方法都有不同的权衡：

如果您只想验证它的格式是否正确，请使用专用的特定解析器，如TMail中的解析器，并查看输入是否被接受（解析成功）（而不是REGEXP）。比如说

一旦知道电子邮件具有正确的格式，您可以更进一步，通过DNS查询“与internet对话”，查看电子邮件的域是否解析并指定了邮件服务器（MX记录），尽管这可能太多了

请在新问题中详细描述您当前的问题，并在此处的链接中留下评论。我相信问题不再是“不兼容的编码regexp匹配（ASCII-8BIT regexp与UTF-8字符串）”，即使您的RFC 822验证器gem没有被“putin-crab@Пззззззззззззззззз。看起来目前允许UTF-8字符的标准是RFC6531，所以如果你想“按部就班”的话，就应该开始寻找这个标准。

#encoding: utf-8
class User
  include Mongoid::Document

  field :email,    :type => String
  validates :email,    :presence => true, :format => { :with => RFC822::EMAIL }
end

ruby-1.9.2-p290 :001 > usr = User.new( :email => "pretty@gmail.com" )
 => #<User _id: 4ec627cf4934db7e4d000001, _type: nil, email: "pretty@gmail.com"> 
ruby-1.9.2-p290 :002 > usr.valid?
 => true

ruby-1.9.2-p290 :003 > usr = User.new( :email => "putin-crab@президент.рф" )
 => #<User _id: 4ec627f44934db7e4d000002, _type: nil, email: "putin-crab@президент.рф"> 
ruby-1.9.2-p290 :004 > usr.valid?
