Question

我们有一个运行延迟工作的应用，用于发送电子邮件。我们遇到了一个问题，其中delayed_job worker接收了n个要处理的作业。查看delayed_job日志，它会处理所有这些。 rails日志显示它接收相同数量的呼叫并且正在处理所有呼叫。但是我们没有收到所有的电子邮件。

日志中没有smtp错误且没有任何失败。我们唯一能够识别的是，当delayed_job日志显示一个项目需要额外的日志时间时，电子邮件无法通过。但日志仍显示一切正常。以下是供参考的日志。

配置中动作邮件程序的设置：

config.action_mailer.delivery_method = :smtp
config.action_mailer.perform_deliveries = true
config.action_mailer.raise_delivery_errors = false
config.action_mailer.default :charset => "utf-8"  

config.action_mailer.smtp_settings = {
    :address   => "smtp.gmail.com",
    :port      => 25,
    :user_name => ENV["GMAIL_USERNAME"],
    :password  => ENV["GMAIL_PASSWORD"]
}

Answer 1

在此处添加您想要的Gmail帐号ENV [“abc@gmail.com”]和密码ENV [“123456”]

Answer 2

提出交货错误，以便找到原因：

config.action_mailer.raise_delivery_errors = true

提供其他参数：

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

在您调用电子邮件方法的地方，在末尾添加“.deliver”，即：

UserMailer.welcome_email(@user).deliver

对于后台作业，您可以将此代码段放在异常块中，并可以使用ExceptionNotification gem发送电子邮件，其中包含有助于您轻松捕获并找到失败原因的详细信息。
