Question

我在此应用程序中使用过的宝石

gem 'redis', '~> 3.0'

gem 'sidekiq'

gem 'bunny'

这是使用者部分，可以从队列中获取消息作为rake任务。

task :do_consumer => :environment do

  connection = Bunny.new(ENV['CLOUDAMQP_URL'])

  connection.start # start a communication session with the amqp server

  channel = connection.channel()

  queue = channel.queue('order-queue', durable: true)

  puts ' [*] Waiting for messages. To exit press CTRL+C'

  queue.subscribe(manual_ack: true, block: true) do |delivery_info, 
   properties, payload|
     puts " [x] Received #{payload}"
     puts " [x] Done"

     channel.ack(delivery_info.delivery_tag, false)
     # Call worker to do task
     callSidekiqWorker.perform_async(payload)
  end
end

Procfile

web: bundle exec puma -C config/puma.rb
worker: bundle exec sidekiq -e production
worker: bundle exec rake do_consumer

我在heroku中添加了 redistogo 插件，并将REDIS_PROVIDER配置为ENV变量。

这里的问题在本地工作正常，但是当我按下heroku之后，我在日志中收到此错误：

我在heroku中做任何错误的配置吗？我也认为这个耙任务并不总是在听。

rabbitMQ（兔子宝石）+ sidekiq在Heroku中无法用于红宝石应用程序
