尝试发送电子邮件时,"必须先发出STARTTLS命令"

Question

我在尝试使用action_mailer_tls插件在我的Rails应用中与Gmail通信时遇到错误:

Must issue a STARTTLS command first

其他人似乎遇到了同样的问题:

问题是Gmail需要TLS身份验证,但标准的Ruby net/smtp库不支持TLS.

本文建议按照以下步骤操作:

当然,Marc Chung创建了一个有用的插件来克服这个障碍.您可以在此处找到它并手动将其添加到项目中,也可以将其导出到插件目录中.

1. $ cd vendor/plugins
2. $ svn export http://code.openrain.com/rails/action_mailer_tls/

无论哪种方式,请确保您需要'smtp_tls'

现在你需要的是更新你的smtp_settings,如果你还没有这样做的话.

1. ActionMailer :: Base.smtp_settings = {
2. :address =>"smtp.gmail.com",
3. :port => 587,
4. :domain =>"domain.com",
5. :user_name =>"user@domain.com",
6. :password =>"密码",
7. :authentication =>:plain
8. }

任何有关与Gmail交谈的更好解决方案的建议都将受到赞赏.

我使用Alexander Pomozov的解决方案从我的Rails应用程序与Gmail交谈.我相信原始文章已经消失,但有人在此处复制了Google缓存.

LIB/smtp_tls.rb

require "openssl"
require "net/smtp"

Net::SMTP.class_eval do
  private
  def do_start(helodomain, user, secret, authtype)
    raise IOError, 'SMTP session already started' if @started
    check_auth_args user, secret, authtype if user or secret

    sock = timeout(@open_timeout) { TCPSocket.open(@address, @port) }
    @socket = Net::InternetMessageIO.new(sock)
    @socket.read_timeout = 60 #@read_timeout
    #@socket.debug_output = STDERR #@debug_output

    check_response(critical { recv_response() })
    do_helo(helodomain)

    if starttls
      raise 'openssl library not installed' unless defined?(OpenSSL)
      ssl = OpenSSL::SSL::SSLSocket.new(sock)
      ssl.sync_close = true
      ssl.connect
      @socket = Net::InternetMessageIO.new(ssl)
      @socket.read_timeout = 60 #@read_timeout
      #@socket.debug_output = STDERR #@debug_output
      do_helo(helodomain)
    end

    authenticate user, secret, authtype if user
    @started = true
  ensure
    unless @started
      # authentication failed, cancel connection.
      @socket.close if not @started and @socket and not @socket.closed?
      @socket = nil
    end
  end

  def do_helo(helodomain)
    begin
      if @esmtp
        ehlo helodomain
      else
        helo helodomain
      end
    rescue Net::ProtocolError
      if @esmtp
        @esmtp = false
        @error_occured = false
        retry
      end
      raise
    end
  end

  def starttls
    getok('STARTTLS') rescue return false
    return true
  end

  def quit
    begin
      getok('QUIT')
    rescue EOFError, OpenSSL::SSL::SSLError
    end
  end
end

到config/environment.rb

(添加其他所有内容后)

    require “smtp_tls”

    ActionMailer::Base.smtp_settings = {
    :address => “smtp.gmail.com”,
    :port => 587,
    :authentication => :plain,
    :user_name => “someone@openrain.com”,
    :password => ’someonesPassword’
    } 

正常使用ActionMailer.

Answer 2

使用Ruby 1.8.7和Rails 2.3.4(虽然已经有几个版本),但是通过使用该:enable_starttls_auto选项,我已经成功,而不需要特定于TLS的ActionMailer插件.示例配置(来自生产环境)如下所示:

ActionMailer::Base.smtp_settings = {
  :enable_starttls_auto => true,
  :address => "smtp.gmail.com",
  :port => 587,
  :domain => "domain.com",
  :authentication => :plain,
  :user_name => "username@domain",
  :password => "secret"
}
