當新用戶註冊使用設計時，電子郵件不發送

Question

我有我的用戶模型，用戶設計，我添加了一個郵件發送自己的電子郵件，當用戶註冊。當我運行我的代碼時，我沒有錯誤。在命令行中，它表示電子郵件已發送，但我什麼都沒有收到。你覺得是什麼原因呢。

我welcome_mailer：

class WelcomeMailer < ApplicationMailer 

    default :from => "jasonbig@gmail.com" 

    def welcome_send(user) 
     @user = user 
     mail to: "jasonbig@gmail.com", subject: "New user added", from: "jasonbig@gmail.com" 
    end 

end 

應用郵包：

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

我的用戶模型：

class User < ActiveRecord::Base 

    # Include default devise modules. Others available are: 
    # :confirmable, :lockable, :timeoutable and :omniauthable 
    devise :database_authenticatable, :registerable, 
     :recoverable, :rememberable, :trackable, :validatable 


    after_create :welcome_send 

    def welcome_send 
    WelcomeMailer.welcome_send(self).deliver 
    end 

end 

Welcome_mailer視圖（welcome_send.html.erb）：

<h1>Hello, <%= @user.email %> has been added</h1> 

development.rb在配置（也許錯誤是在SMTP設置）：

Rails.application.configure do 


    config.cache_classes = false 

    config.eager_load = false 


    config.consider_all_requests_local  = true 
    config.action_controller.perform_caching = false 
    config.action_mailer.delivery_method = :smtp 

    # these options are only needed if you choose smtp delivery 
    config.action_mailer.smtp_settings = { 
    :address  => 'smtp.gmail.com', 
    :port   => 25, 
    :domain   => 'gmail.com', 
    :authentication => :login, 
    :user_name  => 'jasonbig', 
    :password  => 'I have entered my actual password here' 
    } 

    config.action_mailer.raise_delivery_errors = true 

    config.action_mailer.perform_deliveries = true 

    config.active_support.deprecation = :log 

    config.active_record.migration_error = :page_load 

    config.assets.debug = true 

    config.assets.digest = true 

    config.assets.raise_runtime_errors = true 

end 

這是我所涉及的ActionMailer的唯一文件。如果我必須添加更多文件或更改某些內容，請讓我知道。

我的命令行電子郵件發送確認：

Answer 1

繼Rails Guide：

config.action_mailer.delivery_method = :smtp 
config.action_mailer.smtp_settings = { 
    address:    'smtp.gmail.com', 
    port:     587, 
    domain:    'example.com', 
    user_name:   '<username>', 
    password:    '<password>', 
    authentication:  'plain', 
    enable_starttls_auto: true 
} 

我想補充一點CONFIGS：

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

和在Gmail中看到，如果你已經啓用2F權威性

Answer 2

嘗試用：

config.action_mailer.smtp_settings = { 
    :address  => 'smtp.gmail.com', 
    :port   => 587, 
    :domain   => 'gmail.com', 
    :authentication => :login, 
    :user_name  => 'jasonbig', 
    :password  => 'I have entered my actual password here' 
    :enable_starttls_auto => true 
} 

Answer 3

嘗試

:authentication => :plain, 

此外，如果你有兩個因素身份驗證您的Gmail帳戶，您需要按照本文檔中的說明： https://support.google.com/accounts/answer/6010255?hl=en 並替換

:password => LESS_SECURE_APP_GMAIL_PASSWORD,
