Net :: SMTPAuthenticationError

Question

我想設置我的rails 4應用程序，所以它發送電子郵件。有誰知道爲什麼我收到：

Net::SMTPAuthenticationError 
534-5.7.9 Application-specific password required. 

??????

我正在使用設計，並剛剛設置了一個單獨的「共享」郵件發送電子郵件。我嘗試按照其他對此類問題的回覆中的建議去accounts.google.com/b/0/DisplayUnlockCaptcha，但是當我重新啓動服務器並嘗試以用戶身份發送電子郵件時，沒有任何更改。

有什麼想法？乾杯!

配置/環境/ development.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 

    # Gmail SMTP server setup 
    ActionMailer::Base.smtp_settings = { 
    :address => "smtp.gmail.com", 
    :domain => "mail.google.com", 
    :port => 587, 
    :authentication => :plain, 
    :user_name => "myrealaddress@gmail.com", 
    :password => "myrealpassword", 
    :enable_starttls_auto => true 
    } 

    # 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 

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

    # false prevents mail from being sent in development environment 
    config.action_mailer.perform_deliveries = true 
end 

郵件/共享：

class Share < ActionMailer::Base 
    default_url_options[:host] = "localhost:3000" 
    default from: "myrealaddress@gmail.com" 

    def profile(profile, destination) 
    @profile = profile 
    mail(to: destination, subject: "sent you stuff") 
    end 
end

這個錯誤是因爲雙因素身份驗證爲您的帳戶啓用。您只需啓用雙因素身份驗證即可使用Gmail帳戶，並生成新的應用程序密碼以用於郵件程序配置。

此處可以生成一個新的gmail應用程序密碼 - https://security.google.com/settings/security/apppasswords。

生成新密碼時，請選擇Mail，對於Select App設置，對於Select Device設置，請選擇Other(Custom name)。

一旦你有新的密碼更新你的郵件配置與谷歌爲您產生的隨機字符串，你應該設置。
