动作电缆在本地订阅，但不在heroku上订阅

Question

我一直在尝试可以在网上找到的所有内容，但没有任何效果。希望大家能看到新的问题。这是我第一次使用ActionCable，在本地一切正常，但是当推送到heroku时。我的日志没有像我的开发服务器那样显示任何可操作的订阅：

[ActionCable] [[e-mail]] MsgsChannel is streaming from msg_channel_34

在发送消息时，我确实看到了，[ActionCable] Broadcasting to msg_channel_34:但没有将它们追加，这是在猜测是否意味着received未访问/调用该方法？

我确实在heroku的日志中注意到它说Listening on tcp://0.0.0.0:5000，开发人员正在localhost：3000监听。我应该以某种方式对我的heroku应用程序有什么看法吗？

以下是相关的配置文件：

程序文件：

web: bundle exec puma -p 5000  ./config.ru  
actioncable: bundle exec puma -p 28080  cable/config.ru  
redis: redis-server

***由于以下评论，我也在尝试。仍然无法正常工作，但是我可以看到它正在监听的端口正在更改，这使我相信它与配置有关吗？：

web: bundle exec puma -p $PORT  ./config.ru  
actioncable: bundle exec puma -p $PORT  cable/config.ru  
redis: redis-server

/cable/config.ru

require ::File.expand_path('../../config/environment',  __FILE__)  
Rails.application.eager_load!

ActionCable.server.config.allowed_request_origins = ["http://localhost:3000"]  
run ActionCable.server

config / environments / development.rb

config.action_cable.allowed_request_origins = ['localhost:3000']
config.action_cable.url = "ws://localhost:3000/cable"

config / environments / production.rb

config.web_socket_server_url = "wss://app-name.herokuapp.com/cable" 
  config.action_cable.allowed_request_origins = ['https://app-name.herokuapp.com', 'http://app-name.herokuapp.com']

config / cable.yml

local: &local  
  adapter: async
  :url: redis://localhost:6379
  :host: localhost
  :port: 6379
  :timeout: 1
  :inline: true
development: *local  
test: *local


production:
  :url: redis:<%= ENV["REDISTOGO_URL"] %>
  adapter: redis

<%= ENV["REDISTOGO_URL"] %> 已设置，通过运行heroku config进行确认

routes.rb

mount ActionCable.server => '/cable'

为什么这对开发人员有效，但对heroku无效？我已经阅读了几个小时，但无法弄清楚。谢谢！！

Answer 1

问题是我的主机是heroku应用，但请求来自自定义域。

解决：

heroku config:set RAILS_HOST "http://www.example.com"

然后在production.rb中：

config.action_cable.url = "wss://#{ENV['RAILS_HOST']}/cable"
