WebSocket connection to 'ws://my-ec2/cable' failed:
Error during WebSocket handshake: Unexpected response code: 404
Guys, I saw this (old) issue a lot here, so it may seem like it is duplicated.伙计们,我在这里经常看到这个(旧)问题,所以它看起来像是重复的。 But in my case, I try very hard to fix this error but I can't.
但就我而言,我非常努力地修复这个错误,但我不能。 I also follow this correction: https://stackoverflow.com/a/55715218/8478892 but no success.
我也遵循此更正: https://stackoverflow.com/a/55715218/8478892但没有成功。
My nginx.conf:我的 nginx.conf:

listen 80 default_server deferred;

And in my cable.yml:在我的 cable.yml 中:
production:
url: redis://http://my-ec2.com:6379
local: &local
url: redis://localhost:6379
development: *local
test: *local
And my environments/production.rb:还有我的环境/production.rb:
Rails.application.configure do
config.cache_classes = true
config.eager_load = true
config.consider_all_requests_local = false
config.public_file_server.enabled = ENV['RAILS_SERVE_STATIC_FILES'].present?
config.active_storage.service = :local
config.action_cable.mount_path = '/cable'
config.action_cable.url = 'ws://my-ec2/cable'
config.action_cable.allow_same_origin_as_host = true
config.action_cable.allowed_request_origins = ["*"]
config.log_level = :debug
config.log_tags = [ :request_id ]
config.action_mailer.perform_caching = false
config.i18n.fallbacks = true
config.active_support.deprecation = :notify
config.log_formatter = ::Logger::Formatter.new
if ENV["RAILS_LOG_TO_STDOUT"].present?
logger = ActiveSupport::Logger.new(STDOUT)
logger.formatter = config.log_formatter
config.logger = ActiveSupport::TaggedLogging.new(logger)
end
config.active_record.dump_schema_after_migration = false
end
Thought of the day for those who are having this problem:为遇到此问题的人考虑的一天:
Setting up ActionCable en localhost had already been a good fight, but setting up in production is an entire war.
在 localhost 上设置 ActionCable 已经是一场精彩的战斗,但在生产环境中设置则是一场完整的战争。
Do you have redis installed on your machine or is it a docker container?您的机器上安装了 redis 还是 docker 容器? I think you are using it with sidekiq, and do you have any sidekiq/redis initializer file under
/config/initializers
?我认为您正在将它与 sidekiq 一起使用,并且
/config/initializers
下是否有任何 sidekiq/redis 初始化程序文件?
In cable.yml
it should be在
cable.yml
中应该是
production:
url: redis://redis:6379/0
After a few days, I managed to solve this problem myself.几天后,我设法自己解决了这个问题。 The main reason for my error is that in my environments / production.rb file, I was saying that the actioncable endpoint was the public ip of my ec2.
我的错误的主要原因是在我的环境/production.rb 文件中,我说可操作端点是我的 ec2 的公共 ip。 But in reality you should put localhost.
但实际上你应该把本地主机。 I used the same configuration I have in development.rb:
我使用了与 development.rb 中相同的配置:
production.rb before: production.rb 之前:
...
config.action_cable.mount_path = '/cable'
config.action_cable.url = 'ws://my_ec2/cable'
config.action_cable.allow_same_origin_as_host = true
config.action_cable.allowed_request_origins = ["*"]
...
production.rb after: production.rb 之后:
...
config.action_cable.disable_request_forgery_protection = true
config.action_cable.url = "ws://localhost:3000/cable"
config.action_cable.allowed_request_origins = [/http:\/\/*/, /https:\/\/*/]
config.action_cable.allowed_request_origins = /(\.dev$)|^localhost$/
...
