通過Heroku上的Ruby代碼發送電子郵件

Question

我在通過Ruby代碼發送電子郵件時遇到問題。你可以看到我的full code on GitHub。

UPDATE：下面的代碼進行了修訂，從@Gaurish

UPDATE2反映建議：看起來像gmail的拒絕登錄嘗試 - 我收到一封電子郵件，提醒我一些未知的應用程序試圖訪問我的帳戶，但他們關閉它

的具體類是在這裏：

require 'net/smtp' 

=begin 
    http://apidock.com/ruby/v1_9_3_125/Net/SMTP/start/class 
    https://devcenter.heroku.com/articles/config-vars 

    I added the following config vars to Heroku 
    heroku config:add GM_USR=xxxx 
    heroku config:add GM_PSW=xxxx 
=end 

class Email 
    def initialize (to, from, subject, body) 
      @to = to 
      @from = from 
      @subject = subject 
      @body = body 
      @message = <<MESSAGE_CONTENT 
       From: User <#{@from}> 
       To: Integralist <#{@to}> 
       MIME-Version: 1.0 
       Content-type: text/html 
       Subject: #{@subject} 
       #{@body} 
MESSAGE_CONTENT 

      @smtp = Net::SMTP.new('smtp.gmail.com', 587) 
     end 

     def send_email 
      @smtp.enable_starttls 
      @smtp.start('furious-wind-9309.herokuapp.com', ENV['GM_USR'], ENV['GM_PSW'], :login) do |smtp| 
      @smtp.send_message(@message, @from, @to) 
     end 
    end 
end 

我打電話它像這樣：

email = Email.new('myemail@gmail.com', params[:email], 'test subject', params[:message]); 
email.send_mail 

但是，當我執行的代碼，我得到屏幕上顯示的錯誤：535-5.7.1 Please log in with your web browser and then try again. Learn more at

我檢查了日誌，我得到...

我知道人們可能會提出的ActionMailer或小馬，但我寧願不使用那些或者請求那些建議給我的人。相反，我希望能夠幫助解決上述問題的解決方案。

如果Gmail沒有爲你工作，你可以使用SendGrid Addon，讓你每天高達200emails不收取任何費用。

下面是關於如何使用他們的STMP API與使用Sendgrid mail gem

require 'mail' 
Mail.defaults do 
    delivery_method :smtp, { :address => "smtp.sendgrid.net", 
          :port  => 587, 
          :domain => "yourdomain.com", 
          :user_name => "yourusername@domain.com", 
          :password => "yourPassword", 
          :authentication => 'plain', 
          :enable_starttls_auto => true } 
end 

mail = Mail.deliver do 
    to 'yourRecipient@domain.com' 
    from 'Your Name <name@domain.com>' 
    subject 'This is the subject of your email' 
    text_part do 
    body 'Hello world in text' 
    end 
    html_part do 
    content_type 'text/html; charset=UTF-8' 
    body '<b>Hello world in HTML</b>' 
    end 
end 

樣品（來自docs拍攝）是更好的解決方案，因爲你還可以獲得高級報告& analyticss這是不可用的Gmail 。此外，sendgrid中的「from」地址沒有限制。

隨着Heroko，你不能直接從localhost發送電子郵件，因爲Heroku does not provide an outgoing mail service。

所以你將不得不考慮一個外部 smtp服務器發送您的電子郵件。流行的是Gmail & Sendgrid

這只是使用像heroku這樣的雲計算平臺的一種權衡。

使用Gmail，嘗試做這樣的事情：

require 'net/smtp' 

    msg = "your message goes here" 
    smtp = Net::SMTP.new 'smtp.gmail.com', 587 
    smtp.enable_starttls 
    smtp.start(YourDomain, YourAccountName, YourPassword, :login) do 
     smtp.send_message(msg, FromAddress, ToAddress) 
    end 

Answer 2

如果你嘗試：

@email = Email.new('mark.mcdx@gmail.com', params[:email], 'test subject', params[:message]) 
@email.send_email

只加載了SendGrid作爲一個附加的和它的作品開箱的。另外，您還可以獲得整套分析工具，用於故障排除反彈，交付等...
