使用Gmail Smtp 发送email (rails2.0)

ActionMailer是一个简单的Rails组件,应用程序可以借助它来收发电子邮件。
Gmail－－你必须有一个账号和密码，没有的话快去申请 http://mail.google.com/mail/signup

邮件配置:
在enviroment.rb文件中:

ActionMailer::Base.server_settings = {
  :address => "smtp.gmail.com",
  :port => 587,
  :authentication => :plain,
  :user_name=> "gmail­_account",
  :password => "gmail_password"
}

如果按照上面的配置，一般邮件发送会不成功，因为gmail需要ssl方式来登录，ruby的lib中Net:SMTP TLS不支持,所以我们必须去下载一个plugin :
cd /my_rails_app/vendor/plugins
svn export https://openrain.com/opensource/public/rails/plugins/action_mailer_tls action_mailer_tls
为什么不用script/plugin install,我也不知道

下载成功之后，在config/initializers文件夹create一个ruby文件:smptp_gmail.rb

require "smtp_tls" #刚才下载的文件
mailer_config = File.open("#{RAILS_ROOT}/config/mailer.yml")
mailer_options = YAML.load(mailer_config)
ActionMailer::Base.delivery_method = :smtp
ActionMailer::Base.default_charset = "utf-8"
ActionMailer::Base.smtp_settings = mailer_options

然后在config文件夹create一个yml文件:mailer.yml

:address: smtp.gmail.com
:port: 587
:user_name: gmail­_account
:password: gmail_password
:authentication: :plain

最后就可以script/generate mailer MyMailer send

class MyMailer < ActionMailer::Base
  def send
    recipients = 'receiver email address' #接收者email地址
    from = 'your email address' #发送者email地址
    subject = 'i love ruby on rails'
    body[:account] = 'selina'
  end
end

开始发送: script/console
MyMailer.create_send #建一个email对象
MyMailer.deliver_send #发送email

最最最后:
其实把email stmp的配置文件写成一个yml文件的好处在于，如果你要改变stmp服务器的配置,直接再写一个yml文件就可以,比如A.yml , B.yml , C.yml ......
然后再File.open("#{RAILS_ROOT}/config/X.yml")

或者你觉得麻烦，也可以直接在enviroment.rb文件中:

require 'smtp_tls'
ActionMailer::Base.delivery_method = :smtp
ActionMailer::Base.default_charset = "utf-8"
ActionMailer::Base.server_settings = {
  :address => "smtp.gmail.com",
  :port => 587,
  :authentication => :plain,
  :user_name=> "my_gmail­_account",
  :password => "my_gmail_password"
}
