我最近把我的rails项目从Rails4切换到5.0.0.beta3来使用真棒ActionCable。
我的ActionCable服务器在独angular兽内运行。 在开发中一切正常。 在生产中，我有
Started GET "/cable" for xxx.xxx.xxx.xxx at 2016-03-28 18:06:38 +0300 Started GET "/cable/" [WebSocket] for xxx.xxx.xxx.xxx at 2016-03-28 18:06 Successfully upgraded to WebSocket (REQUEST_METHOD: GET, HTTP_CONNECTION: Upgrade, HTTP_UPGRADE: websocket) Registered connection (189772ff-6229-48f1-ae7f-d9a96ad3a6c3) Finished "/cable/" [WebSocket] for xxx.xxx.xxx.xxx at 2016-03-28 18:06:35 而这个信息在一个循环中反复重复。
我已经在stackoverflow尝试了很多选项来处理这个，但没有什么帮助。 我的nginxconfiguration：
upstream unicorn { server unix:/tmp/unicorn.my_app.sock fail_timeout=0; } server { server_name www.my_app.com; return 301 $scheme://my_app.com$request_uri; } server { listen 80 default deferred; server_name my_app.com; root /var/www/my_app/current/public; location ^~ /assets/ { gzip_static on; expires max; add_header Cache-Control public; } try_files $uri/index.html $uri @unicorn; location @unicorn { proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_redirect off; proxy_pass http://unicorn; } location /cable { proxy_pass http://unicorn/cable; proxy_http_version 1.1; proxy_set_header Upgrade websocket; proxy_set_header Connection Upgrade; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } error_page 500 502 503 504 /500.html; keepalive_timeout 5; }
为了确保请求被允许，我已经在初始化程序中临时使用这个代码： ActionCable.server.config.disable_request_forgery_protection = true
我的cable.coffee文件
@App ||= {} App.cable = ActionCable.createConsumer "/cable"
我的config/cable.yml文件
production: adapter: redis url: redis://localhost:6379/1
在这个问题上我不是很有经验，所以任何帮助都会很棒。
在location /cable线段需要添加一行proxy_set_header Host $http_host;
应该：
location /cable { proxy_pass http://unicorn/cable; proxy_http_version 1.1; proxy_set_header Upgrade websocket; proxy_set_header Connection Upgrade; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; }
我实现了机架超时 。 设置正确的超时更正了我的问题。 设置这些变量的正确方法是在config.ru使用语句中，如下所示：
use Rack::Timeout, service_timeout: 5
这是我用于我的网站的配置，似乎工作正常（Rails 5 + Nginx + Unicorn + Capistrano）。 包括你看到的代码片段是从h5bp / server-configs-nginx ，但我不认为他们可能是你的配置不起作用的原因。
