在Rails中发送邮件4.1

所以我遇到了一个我从未见过的有趣错误。 我正在尝试在开发中设置邮件，以便我可以向我自己发送实际的电子邮件。 那么让我们来看看我如何设置邮件

我有一个名为setup_mail.rb的初始化程序

 ActionMailer::Base.smtp_settings = { :address => 'smptp.gmail.com', :port => 587, :domain => "gmail.com", :user_name => Figaro.env.EMAIL, :password => Figaro.env.PASSWORD, :authentication => 'plain', :enable_starttls_auto => true } ActionMailer::Base.default_url_options[:host] = Figaro.env.HOST 

从那里我们在邮件程序目录中有一个名为user_mailer.rb的邮件程序类

 class UserMailer  "#{user.first_name} ", :subject => 'Welcome to AisisPlatform!') end def password_reset(user) @user = user mail(:to => "#{user.first_name} ", :subject => 'Password Reset (AisisPlatform)') end end 

它对所述邮件的HTML和非HTML版本都有适当的视图。 然后我们做：

 UserMailer.registration_confirmation(@user).deliver 

在用户create控制器发送邮件，但在提交表单和创建用户后，我立即得到：

 SocketError (getaddrinfo: nodename nor servname provided, or not known) 

所以我想，让我们看看日志（警告它很长）：

到底是怎么回事？ 为什么我收到此错误？ 我跟着Ryan Bates设置邮件。 它已经过时了吗？

Answer 1

该错误告诉您Ruby无法找到SMTP服务器的DNS条目。

这是因为你的配置中有一个拼写错误，它的smtp.gmail.com而不是smptp.gmail.com 。 此外， domain应该是您的域名，而不是gmail.com ：

 ActionMailer::Base.smtp_settings = { :address => 'smtp.gmail.com', :port => 587, :domain => 'aisisplanner.com', :user_name => Figaro.env.EMAIL, :password => Figaro.env.PASSWORD, :authentication => 'plain', :enable_starttls_auto => true }
