連接被拒絕-“ localhost”端口587的connect（2）

Question

嘗試創建用戶時，我在開發中遇到此錯誤。 誰能啟發我做錯了什么？

users_controller.rb

  def create
    @user = User.new(user_params)
    if @user.save
      session[:user_id] = @user.id
      UserMailer.signup_confirmation(@user).deliver_now
      redirect_to user_tasks_path(current_user.id), notice: "Thank you for signing up!"
    else
      render "new"
    end
  end

環境/開發.rb

Rails.application.configure do
  # Settings specified here will take precedence over those in config/application.rb.

  # In the development environment your application's code is reloaded on
  # every request. This slows down response time but is perfect for development
  # since you don't have to restart the web server when you make code changes.
  config.cache_classes = false

  # Do not eager load code on boot.
  config.eager_load = false

  # Show full error reports and disable caching.
  config.consider_all_requests_local       = true
  config.action_controller.perform_caching = false

  # Don't care if the mailer can't send.
  config.action_mailer.raise_delivery_errors = true

  config.action_mailer.delivery_method = :smtp

  config.action_mailer.smtp_settings = {
  adress: "smtp@gmail.com",
  port: 587,
  authentication: "plain",
  enable_starttls_auto: true,
  user_name: ENV["GMAIL_USERNAME"],
  password: ENV["GMAIL_PASSWORD"]
  }

  # Print deprecation notices to the Rails logger.
  config.active_support.deprecation = :log

  # Raise an error on page load if there are pending migrations.
  config.active_record.migration_error = :page_load

  # Debug mode disables concatenation and preprocessing of assets.
  # This option may cause significant delays in view rendering with a large
  # number of complex assets.
  config.assets.debug = true

  # Asset digests allow you to set far-future HTTP expiration dates on all assets,
  # yet still be able to expire them through the digest params.
  config.assets.digest = true

  # Adds additional error checking when serving assets at runtime.
  # Checks for improperly declared sprockets dependencies.
  # Raises helpful error messages.
  config.assets.raise_runtime_errors = true

  # Raises error for missing translations
  # config.action_view.raise_on_missing_translations = true
end

mailers / application_mailer.rb

class ApplicationMailer < ActionMailer::Base
  default from: "alexnotonfire@example.com"
  layout 'mailer'
end

mailers / user_mailer.rb

class UserMailer < ApplicationMailer

  # Subject can be set in your I18n file at config/locales/en.yml
  # with the following lookup:
  #
  #   en.user_mailer.signup_confirmation.subject
  #
  def signup_confirmation(user)
    @user = user

    mail to: user.email, subject: "Sign Up Confirmation"
  end
end

Thank you for signing up!

嘗試傳遞郵件時，gmail拒絕連接。 我遇到了幾乎相同的問題，最近我發現我沒有在ping gmail系統上啟用telnet客戶端。 因此，我在系統（Windows 7）上啟用了telnet客戶端。 還要運行telnet測試以排除連接故障。 我已經按照此鏈接[ http://techblissonline.com/troubleshoot-gmail-smtp-server-connection/]http://techblissonline.com/troubleshoot-gmail-smtp-server-connection/進行了telnet測試。 如果您能夠ping通gmail仍然出現錯誤，請轉到gmail設置，並允許安全性較低的應用訪問您的帳戶。
