Actioncable Nginx 和 Puma WebSocket 握手：意外响应

Question

我正在尝试使用 rails 5、Nginx 和 Puma 配置服务器。该应用程序运行正常，但 Actioncable 正在提供

WebSocket connection to 'ws://server_name.com/cable' failed:
Error during WebSocket handshake: Unexpected response code: 200

以下是我的 nginx 设置，

upstream app {
  server unix:/tmp/app.sock fail_timeout=0;
}

server {
    listen       80;
    server_name  server_name.com;
    try_files $uri/index.html $uri @app;
    client_max_body_size 100M;
    location @app {
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header Host $http_host;
      proxy_redirect off;
      proxy_pass http://app;
      client_max_body_size 10M;
    }

    location /cable {
       proxy_pass http://app/;
       proxy_http_version 1.1;
       proxy_set_header Upgrade $http_upgrade;
       proxy_set_header Connection "Upgrade";
    }

    location ~ ^/(assets|uploads)/ {
        root assets_path;
        gzip_static on;
        expires max;
        add_header Cache-Control public;
        add_header ETag "";
        break;
    }
    error_page   500 502 503 504  /500.html;
 }

在rails中production.rb，我做了如下设置。

config.action_cable.url = 'ws://server_name.com/cable'

如有任何帮助，我们将不胜感激。

Answer 1

尝试使用，

location /cable {
    proxy_pass http://app; # not http://app/;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "Upgrade";
}

如果您没有 ssl

，还要确保您的 production.rb 中有 config.action_cable.allowed_request_origins = [/http:\/\/*/, /https:\/\/*/]

Answer 2

尝试添加：

config.action_cable.allowed_request_origins = ['*']
config.action_cable.disable_request_forgery_protection = true

到您的 config/environments/production.rb 文件

它对我有用，你也可以查看 this link。而这个
