生产中的Rails 5动作电缆SSL – WebSocket连接失败：WebSocket握手期间出错：意外响应301

[weixin_38067080]

我正在尝试使用rails 5.0.0beta3和websockets运行应用程序.我在开发本地工作的所有东西,但在生产中我在浏览器的控制台中得到这个响应： “WebSocket连接失败：WebSocket握手期间出错：意外响应301” 这是我的nginx conf. upstream app { server unix:/home/dev/workspace/my_app/tmp/sockets/thin.0.sock max_fails=1 fail_timeout=15s; server unix:/home/dev/workspace/my_app/tmp/sockets/thin.1.sock max_fails=1 fail_timeout=15s; } server { listen 443 ssl; server_name www.my_app.co; root /home/dev/workspace/my_app/public; try_files $uri/index.html $uri @app; location @app { proxy_next_upstream error timeout http_502 http_503; proxy_read_timeout 60s; proxy_pass http://app; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_set_header X-FORWARDED-PROTO $scheme; proxy_redirect off; } location /websocket/ { proxy_pass http://localhost:28080/; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "Upgrade"; } error_page 500 502 503 504 /500.html; client_max_body_size 4G; keepalive_timeout 10; ssl on; ssl_certificate /ssl/www.my_app.co.crt; ssl_certificate_key /ssl/www.my_app.co.key; ssl_session_timeout 5m; ssl_protocols TLSv1 TLSv1.1 TLSv1.2; ssl_ciphers "HIGH:!aNULL:!MD5 or HIGH:!aNULL:!MD5:!3DES"; ssl_prefer_server_ciphers on; } 我正在为我的app服务器运行瘦身,并在本地运行websots服务器和redis.我试图在这里遵循动作电缆示例应用程序：https://github.com/rails/actioncable-examples. 我正在启动我的puma服务器：bundle exec puma -p 28080 cable / config.ru 在配置中使用这个puma.rb： workers 1 threads 1, 10 app_dir = File.expand_path("../..", __FILE__) shared_dir = "#{app_dir}/shared" rails_env = ENV['RAILS_ENV'] || "production" environment rails_env stdout_redirect "#{shared_dir}/log/puma.stdout.log", "#{shared_dir}/log/puma.stderr.log", true pidfile "#{shared_dir}/pids/puma.pid" state_path "#{shared_dir}/pids/puma.state" 这是我的production.rb配置的相关部分： config.action_cable.allowed_request_origins = ['https://www.chatben.co', 'https://45.55.192.195'] config.action_cable.url = "wss://www.chatben.co/websocket" config.force_ssl = false 这是我的development.rb配置： config.action_cable.url = "ws://localhost:28080" config.action_cable.allowed_request_origins = ['http://localhost:3000'] config.action_cable.disable_request_forgery_protection = true 在我的应用程序中,我像这样开始我的电缆： @App = {} App.cable = ActionCable.createConsumer() 任何建议都会很棒.我在这里注意到了一个人：RoR 5.0.0 ActionCable wss WebSocket handshake: Unexpected response code: 301能够通过使用单独的域来解决这个问题.这是我接下来可能会尝试的,但我希望它不会那样. 在此先感谢您的帮助！对此,我真的非常感激.

问题可能是Rails强制你连接到ssl.由于nginx终止了ssl连接,因此需要设置X-Forwarded-Proto标头以让Rails知道一切正常.这是一个适合我的完整配置： location /cable { proxy_pass http://app; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "Upgrade"; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-Proto https; proxy_redirect off; }
