ruby - SSL_connect returned=1 errno=0 state=未知状态 : unknown protocol

Question

在阅读了很多帖子后，我找不到解决问题的办法。我与 www.smtper.net 进行了测试连接，连接成功。我的 error.log 只告诉我错误:

OpenSSL::SSL::SSLError: SSL_connect returned=1 errno=0 state=unknown state: unknown protocol


app/controllers/passwords_controller.rb:11:in `create'

可能跟我的nginx设置有关系？

问题

我正在尝试通过 mailgun(或 gmail)配置我的 smtp 但没有成功。 我在 developement.rb 中的配置如下:

config.action_mailer.default_url_options = { :host => "xxxxx:8765" } 
config.action_mailer.delivery_method = :smtp
config.action_mailer.perform_deliveries = true
config.action_mailer.smtp_settings = {
   :address => "smtp.gmail.com",
   :port => 587,
   :domain => "mail.google.com",
   :user_name => "xxx@gmail.com",
   :password => "xxxxxx",
   :authentication => :plain,
   :enable_starttls_auto => true
}

错误是在第 11 行创建操作时抛出的:

  AccountMailer.password_reset_email(@account).deliver

我已经在我的开发服务器上安装了 OpenSSL 1.0.1f

如果您尝试此设置并摆脱您当前拥有的所有其他内容，会发生什么:

# /config/environments/development.rb

# Gmail configuration
config.action_mailer.raise_delivery_errors = true
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
  address:              'smtp.gmail.com',
  port:                 587,
  domain:               'example.com',
  user_name:            ENV['EMAIL_USER'],
  password:             ENV['EMAIL_PASS'],
  authentication:       'plain',
  enable_starttls_auto: true
}

我不确定您是否需要使用 smtper.net，但也许看到这个，即使它很旧，它可能仍然可以工作:

您需要设置这些环境变量，因为您显然不应该在 git 存储库中提交凭据。

但也可以查看这些帖子，因为您可能需要为 gmail 做一些其他事情
