Net::SMTPAuthenticationError（需要 530-5.5.1 身份验证。在 了解更多信息）：

Question

我正在关注第 10 章的 Rails 教程。 由于我没有信用卡，我正在尝试发送电子邮件。我是编程新手，所以我只想看看它是如何工作的。

但是，我收到了这个错误。

    Net::SMTPAuthenticationError (530-5.5.1 Authentication Required. Learn more at

      app/models/user.rb:65:in `send_password_reset_email'

谁能告诉我我错过了哪里？

Answer 1

我想建议你跟进

• Railsapps -Send Mail 和

• Railsapps -rails-environment-variables

一定能帮到你

编辑更新

Allow less secure apps to access accounts

Google 可能会阻止某些应用或设备的登录尝试 不使用现代安全标准。由于这些应用程序和设备 更容易侵入，阻止它们有助于确保您的帐户安全。

一些不支持最新安全的应用示例 标准包括：

• 装有 iOS 6 或更低版本的 iPhone 或 iPad 上的邮件应用程序邮件应用程序

• 在 8.1 版本之前的 Windows 手机上的一些桌面邮件

• Microsoft Outlook 和 Mozilla Thunderbird 等客户端

Answer 2

希望你不要在环境变量ENV中设置用户名和密码，而是写ENV["the actual user name"]

所以它没有通过。

如果您想通过 gmail 发送邮件，请尝试使用 gmail.com

你可以使用

config.action_mailer.smtp_settings = {
    :address              => "smtp.gmail.com",
    :port                 => 587,
    :domain               => "gmail.com",
    :user_name            => "test@gmail.com" #your gmail id
    :password             => "1234" #your gmail password
    :authentication       => :plain,
    :enable_starttls_auto => true
  }

或者如果你想在 env 中设置密码

config.action_mailer.smtp_settings = {
  address: "smtp.gmail.com",
  port: 587,
  domain: "gmail.com",
  authentication: "plain",
  enable_starttls_auto: true,
  user_name: ENV["GMAIL_USERNAME"],
  password: ENV["GMAIL_PASSWORD"]
}

如果您熟悉 Unix，您可能有过设置的经验 环境变量。 Unix 环境变量通常设置在 启动交互式 shell 时读取的文件（~/.bashrc bash shell 的文件）。

为了狂欢 shell，编辑 ~/.bashrc 文件并添加：

export GMAIL_USERNAME="myname@gmail.com" 
export GMAIL_PASSWORD="mypassword"
