rails4.2.6配置发送邮件

调试了很久，最后终于可以发送了

1 在config/environments/development.rb文件里配置邮件信息

config.action_mailer.raise_delivery_errors = true
  config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = {
      :address              => "smtp.163.com",
      :port                 => 25,
      :domain               => '163.com',
      :user_name            => '你的邮箱登陆账号',#例如 [e-mail]
      :password             => '你的密码',
      :authentication       => :login,
  }

2 创建一个基础类 放在 app/mailers目录下

 class ApplicationMailer < ActionMailer::Base
   default from: "邮箱地址" #这里最好和上面配置文件中你的邮箱账户一样，否则可能有奇怪问题
   layout 'mailer'
 end

3 创建一个实际业务逻辑类

class OrderNotifier < ApplicationMailer

  def received

    mail to: "收件人地址", subject: 'Pragmatic Store Order Confirmation'
  end

end

4 view/order_notifier目录下创建对应方法模板，例如 received.text.rb

 <h1>OrderNotifier#received</h1>

 <p>
   test received email
 </p>

5 action中调用邮件类发送邮件

OrderNotifier.received.deliver_now
