ruby-on-rails - Net::SMTPAuthenticationError in Devise::PasswordsController#create when working with devise mailers

Question

我正在为我的应用程序实现设计邮件程序，我已完成以下步骤:

在模型中:

class User < ActiveRecord::Base
  # Include default devise modules. Others available are:
  # :lockable, :timeoutable and :omniauthable
  devise :database_authenticatable, :registerable, :confirmable,
         :recoverable, :rememberable, :trackable, :validatable
end

然后我添加了confirmation_token、confirmed_at、confirmation_sent_at

在 devise.rb 中，我添加了:

  config.mailer_sender = 'example@gmail.com'
  #config.mailer = 'Devise::Mailer'

开发中.rb:

config.assets.raise_runtime_errors = true
config.action_mailer.delivery_method = :smtp
  config.action_mailer.perform_deliveries = true
  config.action_mailer.smtp_settings = {
      :address => "smtp.gmail.com",
      :port => 587,
      :domain => "mail.google.com",
      :user_name => "example@gmail.com",
      :password => "somepassword",
      :enable_starttls_auto => true
  }

一切正常。但是不会生成电子邮件。在我的控制台中，我正在获取邮件信息和链接..

我的控制台:

Sent mail to example@yahoo.com (2597.8ms)

<p>Hello exmple@yahoo.com!</p>

<p>Someone has requested a link to change your password. You can do this through the link below.</p>

<p><a href="http://localhost:3000/users/password/edit?reset_password_token=M5os3tBYHQrsRaw4TtTt">Change my password</a></p>

<p>If you didn't request this, please ignore this email.</p>
<p>Your password won't change until you access the link above and create a new one.</p>

我没有添加任何设计密码 Controller /注册 Controller 。当我单击“忘记密码”并输入电子邮件并单击“向我发送重置密码说明”按钮时出现错误。这是错误，我得到:

Net::SMTPAuthenticationError in Devise::PasswordsController#create

我用了Running into SMTP error when trying to send email in RoR app但没有帮助我。我可能有什么问题？

在谷歌中检查了一些选项后，这个有效

通过使用您在 smtp 配置中提供的电子邮件地址登录，在此处启用对安全性较低的应用程序的访问。
