ActionCable-无法在生产中升级到WebSocket [英] ActionCable - Failed to upgrade to WebSocket in production

问题描述

ActionCable在生产中不起作用.在开发中效果很好，但在生产中效果不佳.

ActionCable doesn't work in production. Works well in development, but not in production.

在Ubuntu 14.04上使用Puma运行Nginx.我已检查redis服务器是否已启动并正在运行.

Running Nginx with Puma on Ubuntu 14.04. I have checked that redis-server is up and running.

Rails -v 5.0.0.1

cable.yml:

redis: &redis
  adapter: redis
  url: redis://127.0.0.1:6379

production: *redis

development:
  adapter: async

test:
  adapter: async

在production.rb中:

config.action_cable.allowed_request_origins = ["http://mityakoval.com"]

在routes.rb中:

mount ActionCable.server, at: '/cable'

更新:

别忘了重启nginx :)那对我来说是个问题.

Don't forget to restart nginx :) That was the problem for me.

推荐答案

您应将proxy_pass属性的值从http://puma更改为http://puma/cable.

You should change the value of proxy_pass property from http://puma to http://puma/cable.

因此，/cable的正确location部分将为:

Therefore, the correct location section for the /cable will be:

location /cable {
  proxy_pass http://puma/cable;
  proxy_http_version 1.1;
  proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  proxy_set_header Host $http_host;
  proxy_set_header Upgrade $http_upgrade;
  proxy_set_header Connection "Upgrade";
}
