Ruby on rails Actioncable Nginx和Puma WebSocket握手：意外响应

我正在尝试用rails 5、Nginx和Puma配置服务器。应用程序运行良好，但Actioncable正在提供

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

下面是我的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production.rb中的rails中，我做了如下设置

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

任何帮助都将不胜感激

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";
}

并且还要确保您的production.rb中有

config.action\u cable.allowed\u request\u origins=[/http:\/\/*/，/https:\/\/*/]

，如果您没有ssl，请尝试添加：

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

到您的

config/environments/production.rb

文件

它和我一起工作，你也可以检查。

这

试着使用

ws://server\u name.com/cable/websocket

这不是工作伙伴。你找到解决方法了吗？我也被这件事缠住了。
