我试了所有我能在网上找到的东西,但都不起作用。希望一些新人能看到这个问题。这是我第一次使用ActionCable,一切都在本地运行得很好,但在推送到heroku时。我的日志没有显示任何像我的dev服务器那样的actioncable订阅:
[ActionCable] [email@email.com] MsgsChannel is streaming from msg_channel_34当发送消息时,我确实看到了[ActionCable] Broadcasting to msg_channel_34:,但它们没有被追加,我猜这意味着received方法没有被访问/调用?
我确实注意到heroku的日志上写着Listening on tcp://0.0.0.0:5000,而作为开发人员,它正在监听本地主机: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:
Procfile:
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,我也在尝试。仍然不能工作,但我可以看到它正在侦听的端口正在改变,这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/environment/development.rb
config.action_cable.allowed_request_origins = ['localhost:3000']
config.action_cable.url = "ws://localhost:3000/cable"config/environment/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

adapter: redis已设置<%= ENV["REDISTOGO_URL"] %>,通过运行heroku config确认
routes.rb
mount ActionCable.server => '/cable'为什么这在dev上有效,而在heroku上无效?我已经读了好几个小时了,但还是想不明白。谢谢!

你的应用程序名是字面上的app-name吗?我想不会。这些值很有可能是。
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']需要更新以使用您要连接到的实际面向公众的URL。
