Ruby on Rails:使用Action Mailer寄信(使用 google smtp)

在Ruby on Rails環境下要發送email,以下是步驟:

一.修改設定檔
修改config/application.rb,加入以下

config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
  address:              'smtp.gmail.com',
  port:                 587,
  domain:               'gmail.com',
  user_name:            'your mail address',
  password:             'your mail password',
  authentication:       'plain',
  enable_starttls_auto: true  }

二.在app/mailers/下增加user_mailer.rb

class UserMailer < ActionMailer::Base
  default from: 'notifications@example.com'
  def welcome_email(user)
    @user = user
    @url  = 'http://example.com/login'
    mail(to: @user.email, subject: 'Welcome to My Awesome Site')
  end
end

三.增加你的mail template
在app/views/user_mailer目錄下新增sendMail.text.rb

Welcome to example.com, <%= @user.name %>
===============================================
You have successfully signed up to example.com,
your username is: <%= @user.login %>.
To login to the site, just follow this link: <%= @url %>.
Thanks for joining and have a great day!

四.測試看看
之後你就可以在任一controller/action下發送email,呼叫Action Mailer
def sendMail
@user  = User.find(user_id)
UserMailer.sendMail(@user).deliver
end

完成以上步驟應該可以成功寄出email了
