【问题描述】：

我是 ActionMailer 的新手，但我也阅读了有关它的文档。我只是不确定 Devise 是如何处理它的。我正在使用 Rails 5.1，但无法让 Devise 邮件程序在开发中工作。

当我尝试在开发中获取重置密码电子邮件时收到以下错误：

EOFError in Devise::PasswordsController#create
{"utf8"=>"✓",
 "authenticity_token"=>"token info",
 "user"=>{"email"=>"user@email.com"},
 "commit"=>"Send me reset password instructions"}

在服务器日志中：

EOFError (end of file reached):

我已经设置了我的 config/environments/development.rb：

  config.action_mailer.perform_deliveries = true
  config.action_mailer.raise_delivery_errors = true
  config.action_mailer.default_url_options = { :host => 'localhost:3000' }
  config.action_mailer.delivery_method = :smtp

  # Using MailCatcher server -- running @ 1080
  config.action_mailer.smtp_settings = { address: "localhost", port: 1080 }

我正在运行 MailCatcher 服务器。当我设置 'raise_deliver_errors' = false 时，我会看到消息已发送，但 MailCatcher 从未收到任何消息。

我有点困惑，我研究过的每一件事都表明我只需要这样做才能让它工作——如果我不需要的话，我不想玩设计控制器。

谢谢！

【解决方案1】：

我所做的只是把这行代码从

config.action_mailer.delivery_method = :smtp

进入

config.action_mailer.delivery_method = :test

日志中出现了视图，当我在生产环境中配置 Sendgrid 时，电子邮件已正确发送。

编辑：这是在development.rb 文件中
