Ruby on rails SSL上的Websocket（WSS）“；未能升级"；弹性豆茎（ALB、Rails、Nginx、Actioncable）

当我尝试连接到部署在ALB后面的EB上的websocket时，发现404升级失败。大多数问题都与此相关，因此没有答案或不清楚

Real domain被替换为w/example.com

/var/app/current/log/production.log中出错（行缩短）

设置

• 弹性豆茎+ALB（含红宝石的美洲狮2.4）
• HTTPS/WSS/SSL
• 轨道5

config/production.rb：

config.action_cable.url = "wss://usetreasure.com/cable"
config.action_cable.allowed_request_origins = [ '/https:\/\/*/', '/http:\/\/*/' ]

在EB实例/etc/nginx/conf.d/websockets.conf上

upstream puma {
  server unix://var/run/puma/my_app.sock;
}

server {
  listen 443;
  server_name example.com;

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

ALB在HTTP/HTTPS上设置为443和80（但在安全组上显示TCP？）

config.action_cable.url = "wss://usetreasure.com/cable"
config.action_cable.allowed_request_origins = [ '/https:\/\/*/', '/http:\/\/*/' ]

upstream puma {
  server unix://var/run/puma/my_app.sock;
}

server {
  listen 443;
  server_name example.com;

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