我想知道是否有人可以帮助我，在我的Ruby on Rails应用程序中，我试图让系统将特定电子邮件地址（Gmail）的电子邮件发送到特定的电子邮件地址（Gmail），但是由于某种原因，电子邮件不发送 - 但没有错误消息。
在我的控制器中，我有以下代码在保存新记录时发送电子邮件：
def create
@email = Email.new(email_params)
if @email.save
UserMailer.welcome_email.deliver
redirect_to @email
else
render 'new'
end
end
这应该叫这个梅勒：
class UserMailer < ApplicationMailer
default from: 'abc@123.com'
def welcome_email()
mail(to: '123@abc.com', subject: 'Welcome to My Awesome Site')
end
end
我的应用程序邮件程序如下：
class ApplicationMailer < ActionMailer::Base
default from: "abc@123.com"
layout 'mailer'
end
然后我有welcome_email.html.erb：
<!DOCTYPE html>
<html>
<head>
<meta content='text/html; charset=UTF-8' http-equiv='Content-Type' />
</head>
<body>
<h1>Welcome to Thor Cinemas,!</h1>

以上的类似文字版本。
由于某种原因，这不起作用，我在$RAILS_ENV（\config\environments）中有以下内容：
config.action_mailer.delivery_method = :sendmail
config.action_mailer.perform_deliveries = true
config.action_mailer.raise_delivery_errors = true
config.action_mailer.default_options = {from: 'abc@123.com'}
以下位于同一位置的development.rb：
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.raise_delivery_errors = false
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
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
address: 'smtp.gmail.com',
port: 587,
domain: 'example.com',
user_name: '123@abc.com', #replace with your username Eg. john.smith
password: 'mypassword', #replace with your gmail password
authentication: 'plain',
enable_starttls_auto: true }
end
以下production.rb位于同一位置：
Rails.application.configure do
config.cache_classes = true
config.eager_load = true
config.consider_all_requests_local = false
config.action_controller.perform_caching = true
config.serve_static_files = ENV['RAILS_SERVE_STATIC_FILES'].present?
config.assets.js_compressor = :uglifier
config.assets.compile = false
config.assets.digest = true
config.log_level = :debug
config.i18n.fallbacks = true
config.active_support.deprecation = :notify
config.log_formatter = ::Logger::Formatter.new
config.active_record.dump_schema_after_migration = false
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
:address => "smtp.gmail.com",
:port => 587,
:user_name => ENV['EMAIL_USER'],
:password => ENV['EMAIL_PASSWORD'],
:authentication => "plain",
:enable_starttls_auto => true
}
end

创建新记录时我在log中获得的内容如下：

我真的很困惑为什么这不起作用，有人知道吗？
请注意，我使用的是Windows 7并运行Rails 4.2.6。
答案 0 :(得分：1)
我认为你需要使用deliver_now而不是传递。
Encoding.Default希望这对你有用。
答案 1 :(得分：0)
默认情况下，在开发环境中不会发送邮件，添加此内容
`config.action_mailer.perform_deliveries = true`
在您的development.rb中执行交付。如果您使用的是Rails 4，请使用
Notifier.welcome(User.first).deliver_now
根据文档，您也可以使用
Notifier.welcome(User.first).deliver_now!
在不检查perform_deliveries和raise_delivery_errors的情况下发送电子邮件，因此请谨慎使用。
修改
我在PRODUC.rb中看到您的邮件设置中缺少域名，请使用
:domain => "gmail.com",
