ruby-on-rails - ActionCable - Puma - Nginx - SSL

Question

我对 ActionCable 完全陌生...尝试在 Rails 6.0 应用程序(Nginx + Puma)上设置 Action Cable。我还必须说我的环境是在云上(DigitalOcean.com)，那就是 SSL。

我的config/cable.yml:

development:
  adapter: redis
  url: redis://localhost:6379

我的 config/environments/development.rb :我刚刚添加了这行

config.action_cable.allowed_request_origins = ["https://my.url.com/"]
config.action_cable.url = "ws://localhost:3000/cable"

当然:my.url.com 是我的域名。

我收到此错误:

WebSocket connection to 'wss://my.url.com/cable' failed: WebSocket is closed before the connection is established.

有人有想法吗？

非常感谢:-)

将位置 block 添加到您的 nginx 配置文件中。

location /cable {
 proxy_pass http://puma_app;
 proxy_http_version 1.1;
 proxy_set_header X-Forwarded-Proto https;
 proxy_set_header X-Forwarded-Ssl on;
 proxy_set_header Upgrade $http_upgrade;
 proxy_set_header Connection "upgrade";

}

将 puma_app 替换为您的上游名称。
