我在生产中发送电子邮件时遇到问题。一切都在开发中运作良好。具体来说，我只是希望应用程序能够从Devise Gem发送通用电子邮件消息。
这是production.rb中的代码
config.action_mailer.default_url_options = { :host => 'http://ballnow.herokuapp.com' }
config.action_mailer.delivery_method = :smtp
config.action_mailer.raise_delivery_errors = true
config.action_mailer.perform_deliveries = true
config.action_mailer.smtp_settings = {
address: 'smtp.gmail.com',
port: 587,
domain: ENV["GMAIL_DOMAIN"],
authentication: 'plain',
enable_starttls_auto: true,
user_name: ENV["GMAIL_USERNAME"],
password: ENV["GMAIL_PASSWORD"]
}
我觉得这是非常愚蠢的事情，但在过去的几个小时里，我似乎无法弄明白。这是纸质记录中的日志：

您应该将域（而不是URL）设置为默认网址选项主机。只是尝试删除http://
config.action_mailer.default_url_options = { host: 'ballnow.herokuapp.com' }
希望它有所帮助。
