使用 rails 中的邮件表单进行联系：Errno::ECONNREFUSED: Connection denied - connect(2)

Question

在你问之前，我已经连接到互联网。我尝试使用 herokuapp 上的表单和本地主机上的表单，但都不起作用。他们应该发送到我的电子邮件。我还尝试将它与控制台一起使用...

c = Contact.new(:name => 'Jose', :email => 'bob@bob.com', :message => 'blah') c.deliver

这就是我得到这个的地方......

我在 Contact.rb 中的代码

class Contact < MailForm::Base
  attribute :name,      :validate => true
  attribute :email,     :validate => /\A([\w\.%\+\-]+)@([\w\-]+\.)+([\w]{2,})\z/i
  attribute :message
  attribute :nickname,  :captcha  => true

  # Declare the e-mail headers. It accepts anything the mail method
  # in ActionMailer accepts.
  def headers
    {
      :subject => "Someone contacted you on your website!",
      :to => "myemail@gmail.com",
      :from => %("#{name}" <#{email}>)
    }
  end
end

我在haml中的联系表

.row
  .large-8.small-centered.columns
    %div{align: "center"}
      %h2 Send A message to Us
      = form_for @contact, :html => {:class => 'form-horizontal' } do |f|
        .row
          .large-12.columns
            %h2 Name
            = f.text_field :name, :required => true, :placeholder => 'John Smith'
        .row
          .large-12.columns
            %h2 Email
            = f.text_field :email, :required => true, :placeholder => 'You@example.com'
        .row
          .large-12.columns
            %h2 Message
            = f.text_area :message, :as => :text, :required => true, :size => "30x10" 
        .hidden
          = f.text_field :nickname, :hint => 'Leave this field blank!'
        %div
          = f.submit 'Send message'

健身房也安装好了

gem 'mail_form'
gem 'simple_form'

routes.rb

  match '/contacts', to: 'contacts#new', via: 'get'
  resources "contacts", only: [:new, :create]

联系人控制器

class ContactsController < ApplicationController
  def new
    @contact = Contact.new
  end

  def create
    @contact = Contact.new(params[:contact])
    @contact.request = request
    if @contact.deliver
      redirect_to(root_path, :notice => "Thank you for contacting me. I will reply shortly!")
    else
      flash.now[:error] = 'Cannot send message.'
      render :new
    end
  end
end

我的开发配置（本地主机）

 config.action_mailer.raise_delivery_errors = true

  config.action_mailer.default_url_options = { :host => 'localhost:3000' }


  config.action_mailer.delivery_method = :smtp

我的作品（为 Heroku）

config.action_mailer.default_url_options = { :host => 'myapp.herokuapp.com' }

  config.action_mailer.delivery_method = :smtp
  config.action_mailer.perform_deliveries = true
  config.action_mailer.raise_delivery_errors = false
  config.action_mailer.default :charset => "utf-8"

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

我真的不知道它为什么会这样做，并且这里对这个错误的其他解释对我不起作用。

Answer 1

我能够解决这个问题。愚蠢的我忘了添加 gmail 邮件程序。我没有意识到我需要邮件表格。我使用的教程从未放入过此类信息。

config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
  address:              'smtp.gmail.com',
  port:                 587,
  domain:               'gmail.com',
  user_name:            'myname@gmail.com',
  password:             'mypassword',
  authentication:       'plain',
  enable_starttls_auto: true  }

做 rake db:migrate 我花了一个小时在上面，遇到了这个问题 Errno::ECONNREFUSED: Connection denied - connect(2)

然后当我放 rake db:migrate 并再次重新启动服务器时它工作了
