action cable 在本地订阅,但不在 heroku 上订阅

action cable subscribing locally, but not on heroku

我一直在尝试所有可以在网上找到的方法,但没有任何效果。希望一些新鲜的眼睛会看到这个问题。这是我第一次使用 ActionCable,在本地一切正常,但在推送到 heroku 时。我的日志没有像我的开发服务器那样显示任何 actioncable 订阅:

[ActionCable] [email@email.com] MsgsChannel is streaming from msg_channel_34

并且在发送消息时,我确实看到 [ActionCable] Broadcasting to msg_channel_34: 但它们没有附加,我猜这意味着 received 方法不是 accessed/called?

我确实注意到 heroku 的日志上写着 Listening on tcp://0.0.0.0:5000 作为开发者它正在监听 localhost:3000。我应该以某种方式指向我的 heroku 应用程序吗?

相关配置文件如下:

过程文件:

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,但我可以看到它正在侦听的端口正在发生变化,让我相信它与配置有关? :

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,由 运行 heroku config

确认

routes.rb

mount ActionCable.server => '/cable'

为什么这在 dev 上有效,但在 heroku 上无效?我已经阅读了几个小时,但无法弄清楚。谢谢!!

您的 procfile 建议您 运行 puma with cable/cable.ru 在端口 28080 上。另外 - 文件 cable/config.ru 不应该包含此行:

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

您已经在 config/environment/*.rb

中进行了配置

您的应用名称是字面上的 app-name 吗?我怀疑不是。这些值很有可能...

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']

需要更新以使用您打算连接的实际 public-facing URL。

问题是我的主机是 heroku 应用程序,但请求来自自定义域。

求解:

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

然后在production.rb:

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

我遇到了同样的问题,并找到了我需要的答案 here: redis gem 4+ incompatibility "Specified 'redis' for Action Cable pubsub adapter, but the gem is not loaded"。一旦我将我的 redis 降级到 3.1.0,工作完美。
