我在铁路上使用sidekiq发送电子邮件。我为redis服务器添加了密码，但是似乎无法正确输入密码，因为我遇到了错误

我的sidekiq日志显示应该可以吗？

2015-12-10T16:49:39.220Z 10448 TID-ows27pimw INFO: Booting Sidekiq 3.5.3 with redis options {:url=>"redis://localhost:6379/0", :password=>"REDACTED", :namespace=>"sidekiq"}

这是我在初始化程序中的sidekiq.rb

Sidekiq.configure_server do |config|
  config.redis = { :url => "redis://#{}localhost:6379/0", password: ENV["REDIS_PASSWORD"], :namespace => "sidekiq" }
end
