Rails3 中的 ActionMailer 问题。（ssl 主机名与服务器证书不匹配）答案

【问题标题】：Problem with ActionMailer in Rails3. (ssl hostname was not match with the server certificate)Rails3 中的 ActionMailer 问题。（ssl 主机名与服务器证书不匹配）
【发布时间】：2015-10-26 18:28:33
【问题描述】：

这里出现了奇怪的错误，我在我的 rails3 应用程序中注册后设置了一个邮件程序以向用户发送确认信息，它在几天前工作，现在在将其移动到另一台服务器并添加不同的其他功能后，我今天再次尝试了我收到此错误：

OpenSSL::SSL::SSLError in UsersController#create 
hostname was not match with the server certificate

我的初始化程序/setup_mail.rb 文件如下所示

ActionMailer::Base.delivery_method = :smtp # be sure to choose SMTP delivery
ActionMailer::Base.smtp_settings = {  
  :address              => "mailout.eve-images.de",  
  :port                 => 587,  
  :domain               => "eve-images.de",  
  :user_name            => "xxxxxxx-noreply",  
  :password             => "xxxxxxxx",  
  :authentication       => "plain", 
  :enable_starttls_auto =>  true   
}

我的邮件程序/user_mailer.rb 文件

class UserMailer < ActionMailer::Base  
  default :from => "no-reply@eve-images.de"  

  def registration_confirmation(user)  
    mail(:to => user.email, :subject => "Registered")  
  end  
end

还有我的 users_controller

 def create
    @user = User.new(params[:user])
    if @user.save
      UserMailer.registration_confirmation(@user).deliver  
      session[:user_id] = @user.id
      flash[:notice] = "Thank you for signing up! You are now logged in."
      redirect_to "/"
    else
      ....
    end
  end

我已经尝试将 :enable_starttls_auto 设置为 false 并得到相同的错误。另外我希望我的密码和用户被加密......

任何想法都非常感谢！

标签： ruby-on-rails ssl actionmailer ruby-on-rails-3

【解决方案1】：

解决方案：

:openssl_verify_mode => 'none'

【讨论】：

我不喜欢禁用安全性的建议是公认的答案，没有任何解释为什么建议这样做，以及问题的原因是什么。
您好，如果此设置有任何问题，请告诉我您如何识别
有一个explanation here。建议的解决方案仅对 Mailer gem（即 Rails 3+）有效。

【解决方案2】：

用途：

ActionMailer::Base.delivery_method = :sendmail

不是

ActionMailer::Base.delivery_method = :smtp

【讨论】：

如果您的邮件服务器在本地运行并且不需要接受外部连接，这绝对是一个更好的解决方案。
@BrendonMuir 请问使用actionmailer -> postfix -> sendgrid 的意思是“在本地运行”吗？
霍利莫利！我不记得了：D 我现在使用邮戳，他们在他们的 gem :postmark 中有自己的交付方式。我想我的意思是，如果您没有连接到另一台服务器来发送电子邮件（即使用 smtp），那么 :sendmail 方法似乎更简单（不需要凭据）。我不确定我对外部连接部分的意思：) 抱歉，我无法提供更多帮助。

【解决方案3】：

我遇到了同样的问题，但 Franks 的解决方案对我不起作用。我找到了一个沿着相同路径的解决方案。

:enable_starttls_auto => false # changed from true

参考：https://gist.github.com/1021285

【讨论】：

【解决方案4】：

对我来说:enable_starttls_auto => false 没有用，我把它留给了:enable_starttls_auto => true。但是我弄错了，在devise.rb 中我没有取消注释这一行：config.mailer = "Devise::Mailer"。当我删除评论时，一切都在我的本地主机上运行。另一方面，在我托管我的网站的机器上时，我仍然会收到此错误。
