Question

我正在使用Devise进行用户身份验证，使用SendGrid发送电子邮件，并使用Heroku托管我的Rails应用。

问题在于，当用户注册时，SendGrid应该发送确认电子邮件；在用户确认后，它应该发送欢迎电子邮件，但尽管我可以看到Heroku正在通过以下方式发送电子邮件，但SendGrid没有发送这些电子邮件： Heroku日志。

mailers/welcome_email.rb

class WelcomeEmail < ApplicationMailer

    def welcome_email(user)
        @user = user
        mail to: @user.email, subject: "Thanks for joining!", from: "info@app.com"
    end

end

models/user.rb

class User < ApplicationRecord
    devise :database_authenticatable, :registerable,
           :recoverable, :rememberable, :validatable, :confirmable

    def after_confirmation
        WelcomeEmail.welcome_email(self).deliver
    end

end

views/welcome_email.html.erb

<h1>This is the welcome email!</h1>

config/environments/development.rb

Rails.application.configure do

  config.action_mailer.perform_deliveries = true
  config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = { :address => "localhost", :port => 1025 }
  config.action_mailer.default_url_options = { host: 'localhost', port: 3000 }

end

config/environments/production.rb

Rails.application.configure do
  # for emails to go out
  config.action_mailer.default_url_options = { host: 'appname.herokuapp.com', protocol: 'https' }
  config.action_mailer.delivery_method = :smtp
  config.action_mailer.perform_deliveries = true
  config.action_mailer.smtp_settings = {
    :user_name => ENV['SENDGRID_USERNAME'],
    :password => ENV['SENDGRID_PASSWORD'],
    :domain => 'herokuapp.com',
    :address => 'smtp.sendgrid.net',
    :port => 587,
    :authentication => :plain,
    :enable_starttls_auto => true
  }
end

Heroku日志

我到处都是SO，博客文章，视频和指南，但都没有成功。有人可以帮我吗？

Answer 1

您要立即发送电子邮件吗？尝试使用deliver.now代替deliver

Sendgrid未在Heroku生产Rails应用程序上发送电子邮件
