Question

我在通过Ruby代码发送电子邮件时遇到问题。你可以看到我的full code on GitHub。

更新：以下代码已经过修改，以反映@Gaurish的建议

UPDATE2：看起来gmail拒绝了登录尝试 - 我收到了他们的电子邮件，警告我一些未知的应用程序试图访问我的帐户但是他们禁用了它

具体课程在这里：

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

我这样称呼它：

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

但是当我执行代码时，我会在屏幕上显示错误：535-5.7.1 Please log in with your web browser and then try again. Learn more at

我检查了日志，我得到了......

我知道人们可能会建议使用ActionMailer或Pony，但我宁愿不使用那些或者请那些建议给我。我反而喜欢一种有助于修复上述代码的解决方案。

Answer 1

[更新1]

如果gmail不适合您，您可以使用SendGrid Addon，每天最多免费提供200电子邮件。

以下是有关如何将其STMP API与docs

一起使用的示例（摘自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

使用Sendgrid是一个更好的解决方案，因为您还可以访问高级报告＆amp;解析不适用于gmail。此外，sendgrid中的“from”地址没有限制。

使用Heroko，您无法直接从localhost发送电子邮件，因为Heroku does not provide an outgoing mail service。

因此您必须考虑使用外部 smtp服务器来发送电子邮件。受欢迎的是Gmail＆amp; Sendgrid

这只是使用像heroku这样的云计算平台的一个权衡。

使用Gmail，请尝试执行以下操作：

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

如果您尝试：

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

Answer 3

只需将SendGrid作为插件加载即可，它开箱即用。此外，您还可获得一整套分析功能，以便对跳出，交付等进行故障排除......
