带有gmail的邮件程序给出Net :: SMTPAuthenticationError：禁用2因子身份验证

Question

我在我的开发（本地）环境以及当我尝试从我的rails应用程序发送邮件时，我在Heroku上主持了Net::SMTPAuthenticationError。

这是在发送前几封电子邮件（两封邮件具体）后开始的。

到目前为止，所有研究都认为这可能是因为在Gmail帐户上启用了2-factor auth，但是当我检查帐户时，2-factor autt未启用。

下面的

是config/development.rb和config/production.rb中的smtp设置：

  config.action_mailer.delivery_method = :smtp
  # SMTP settings for gmail
  config.action_mailer.smtp_settings = {
      :address              => "smtp.gmail.com",
      :port                 => 587,
      :user_name            => Rails.configuration.gmail_address,
      :password             => Rails.configuration.gmail_password,
      :authentication       => "plain",
      :enable_starttls_auto => true
  }

我的邮件设置如下：

class StackoMailer < ActionMailer::Base

    def success_mail
      @my_email = Rails.configuration.gmail_address
      mail(
        from: 'notifications@StackoProbe.com',
        to: @my_email,
        subject: 'Fuck Yeah! Visited successfully...'
      )
    end
end

在调用PushWatir::StackoMailer.success_mail.deliver_now!时，我收到以下错误：

2.2.1 :001 > PushWatir::StackoMailer.success_mail.deliver_now!
Net::SMTPAuthenticationError: 534-5.7.14 <https://accounts.google.com/ContinueSignIn?sarp=1&scc=1&plt=AKgnsbv8i

导致这种情况的原因是什么？

我该如何使这项工作？非常感谢您的回复

对我有用的解决方案之一是允许我的Google帐户使用“安全性较低的应用”。

执行此操作的步骤如下： -

从您的Google帐户设置中，找到“登录和安全” - ＆gt; “允许安全性较低的应用”，启用它。
