设计中的 EOFError::PasswordsController#create

Question

我遇到了从我的 Ruby on Rails 应用程序邮寄密码重置的问题。密码重置邮件过去可以工作，但现在不行了。密码重置是服务器发送的唯一电子邮件。一旦我提交了我想要获取密码的电子邮件，Rails 就会在完整的跟踪信息中显示：

我的 devise.rb 包含：

config.mailer_sender = "accounts@mydomain.com"

# Configure the class responsible to send e-mails.
config.mailer = 'Devise::Mailer'

我的 development.rb 包含：

config.action_mailer.default_url_options = { :host => 'subdomain.mydomain.com' }
# ActionMailer Config
# Setup for production - deliveries, no errors raised
config.action_mailer.delivery_method = :smtp
config.action_mailer.perform_deliveries = true
config.action_mailer.raise_delivery_errors = true
config.action_mailer.default :charset => "utf-8"

config.action_mailer.smtp_settings = {
  address: "smtp-relay.gmail.com",       port: 465,
  domain: "mydomain.com",
  authentication: "plain",
  enable_starttls_auto: false,
  tls: true
}

我不确定这里到底出了什么问题。电子邮件生成得很好，并显示在服务器日志上。但是，它在尝试发送时遇到 500 错误。

有人知道我应该去哪里看看发生了什么吗？

Answer 1

不正确的 SMTP 设置似乎是许多 EOFErrors 使用 Devise 的原因。

使用 ssl: true 并删除端口 465 的任何 TLS 选项。如果您更愿意使用 TLS，请使用端口 587。

编辑：抱歉，这个建议完全错误。 The tls and ssl options are actually just aliases of each other.

注意：根据this article，邮件客户端经常使用术语“SSL”和“TLS”来指代实际的安全协议本身，而是指通过安全通道启动连接的做法（所以-称为“SSL”）与开始不安全，然后在建立初始握手后切换到加密通信（所谓的“TLS”，但实际上是 STARTTLS）。

为了澄清，你有权开始：

• 端口 465 可以与 ssl: true 或 tls: true 一起使用，并且
• 端口 587 与 enable_starttls_auto: true 一起使用（这是默认设置，因此不需要）。

所以我不知道您的配置有什么问题。你有想过吗？

Answer 2

我在 Rails 6.0.0.rc1 中遇到了这个错误，而 Devise 4.6.2 正在开发中。

解决方法是添加：

    config.action_mailer.default_options = {
      from: 'accounts@mydomain.com'
    }

在 application.rb 中（或在您的 environments/development.rb 中）
