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。希望新的眼睛会看到这个问题。这是我第一次使用ActionCable，在本地一切都很好，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] [[email protected]] 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:，但未附加它们，我猜测这意味着未访问/调用received方法？我确实在heroku的日志中注意到它说
Listening on tcp://0.0.0.0:5000，而dev正在localhost:3000监听。我是否应该以某种方式针对我的heroku应用程序？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
***感谢下面的评论，我也在努力。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
设置了
<%= ENV["REDISTOGO_URL"] %>，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!!

最佳答案
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"
