我有一个使用Gmail发送电子邮件通知的Rails应用程序（它目前仅处于开发模式）。我用这样的环境变量设置用户名和密码
GMAIL_USERNAME='me@gmail.com' GMAIL_PASSWORD='mygreatpassword' rails s
一切正常。但是，在我添加sidekiq / redis以便将电子邮件作为后台作业发送后，我在尝试发送电子邮件时收到身份验证错误。

添加sidekiq之后，我以相同的方式启动了rails服务器，在'rails s'命令之前使用了GMAIL_USERNAME和GMAIL_PASSWORD环境变量。我也这样开始redis
redis-server /usr/local/etc/redis.conf
和sidekiq这样
bundle exec sidekiq
然后，在添加redis之后，我使用sidekiq的'delay'方法而不是'deliver'来发送消息。但是，如上所述，我收到了身份验证错误消息。
def after_create(answer)
answer.question.watchers.each do |user|
Notifier.delay.answer_updated(answer, user)
# Notifier.answer_updated(answer, user).deliver
end
更新
这些是我的配置动作邮件设置
config.action_mailer.smtp_settings = {
address: "smtp.gmail.com",
port: 587,
domain: "localhost:3000",
authentication: "plain",
enable_starttls_auto: true,
user_name: ENV["GMAIL_USERNAME"],
password: ENV["GMAIL_PASSWORD"]
}

答案 0 :(得分：10)
Sidekiq启动它自己的rails环境，并且缺少用于配置ActionMailer的环境变量，这就是使用sidekiq时出现异常的原因，而不是在rails服务器进程内发送时的原因。
基本上你只需要使用与服务器相同的变量启动sidekiq worker：
GMAIL_USERNAME='me@gmail.com' GMAIL_PASSWORD='mygreatpwd' bundle exec sidekiq
虽然这可能会使工作正常，但请考虑使用类似foreman的方法来处理此问题（特别是在开发中）。
答案 1 :(得分：4)
我的猜测是，您在控制台中设置的环境变量仅应用于Web服务器的进程（由rails s启动）。因此，当sidekiq查看邮件程序配置时，它会从ENV["GMAIL_USERNAME"]和ENV["GMAIL_PASSWORD"]返回nil。您需要将这些环境变量放在sidekiq进程可以访问它们的位置。
我将在下面列出几个选项（＃2看起来最简单），但是已经有一些资源已经更详细地解释了这一点（并且为了编译这些选项而得到他们的信任） / em>的。退房：
.env放入.gitignore 我不推荐这种方法，但希望将其作为以下两个选项的对应点。
export GMAIL_USERNAME="myemail@gmail.com"
在bash控制台中运行此功能将在ENV中创建~/.bashrc中的值。
但是，此解决方案不是特定于应用程序的（它可以在您的计算机上的任何位置使用），并且它远离您的应用程序，您可能会发现很难调试问题或忘记删除/更改此私人信息
figaro gem为您提供了.gitignore个YAML文件，您可以将其放入敏感配置信息。
它还提供帮助程序，用于将这些配置变量上传到heroku，同时仍然保持配置不在您的git存储库中。
这几乎就是费加罗宝石所做的事情，但值得理解。
# 1. create a config file
touch config/gmail_config.yml
# 2. add the new file to .gitignore
# 3. add code to application.rb to load yml file
config.before_configuration do
env_file = File.join(Rails.root, 'config', 'local_env.yml')
YAML.load(File.open(env_file)).each do |key, value|
ENV[key.to_s] = value
end if File.exists?(env_file)
end
如果文件退出（即您在本地计算机上），它将加载文件并设置变量。如果该文件不存在，则不会加载该文件，您需要在生产环境中设置该变量。
