我最近安装了 Sidekiq gem，以便在我的 Rails 应用程序的后台进程中发送电子邮件。然而，我还没有收到一封要发送的电子邮件，而 Stack Overflow 的搜索让我空手而归。我对 Sidekiq 或 Redis 没有很好的了解，所以问题的一部分可能是我真的不知道要搜索什么或如何解释错误消息。在安装 Sidekiq 之前，使用 .deliver 方法可以很好地发送电子邮件。
当它尝试再次发送时，我收到一条错误消息“对等方重置连接”，然后是“到达文件结束”。还有一条警告消息，其中包含“sysread_nonblock”并提到了 openssl 目录。

这是我的代码。它基于 Rails 4.2.3 和 Ruby 2.2.1。
宝石文件
gem 'redis'
gem 'sidekiq'
应用程序.rb
config.active_job.queue_adapter = :sidekiq
config.action_mailer.default_url_options = { host: 'localhost', port: 3000 }
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
address: 'smtp.office365.com',
port: 587,
authentication: :login,
user_name: ENV['office_email'],
password: ENV['office_pw'],
domain: 'example.com',
enable_starttls_auto: true
}
问题控制器
QuestionMailer.question_email.deliver_later!
问题邮件
default from: "info@example.com"
def question_email
mail(to: "example@gmail.com", subject: 'Question Email')
end
当我启动本地服务器时，我执行以下操作：
启动 Redis 服务器
redis-server /usr/local/etc/redis.conf
启动 Sidekiq
bundle exec sidekiq -q default -q mailers
启动 Rails Server（带工头）
foreman run rails server
这是我的完整日志：
