nginx ws 无效 URL 前缀

Question

第一次与 nginx.
我有一个 nodejs WebSocket 服务器在 ws://service_name:3600.
监听我正在使用 docker-compose:

version: "2"
services:
   # stuff

   service_name:
      image: imagename
      ports:
        - 3600:3600
      links:
        # stuff
        - proxy

   proxy:
     image: image-from-nginx-with-custom-config
     ports:
       - 80:80
       - 443:443
       - 8443:8443

我的配置：

// stuff 

server {
    listen          8443;
    server_name     localhost;
    ssl on;

    ssl_certificate      /etc/nginx/certs/crt.pem;
    ssl_certificate_key  /etc/nginx/certs/key.pem;

    keepalive_timeout    60;

    proxy_next_upstream error timeout invalid_header http_500 http_502 http_503;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto https;

    location / {
        proxy_pass ws://service_name:3600;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}

我在启动时得到 nginx: [emerg] invalid URL prefix in /etc/nginx/conf.d/default.conf。
所以nginx不识别ws，怎么办？

Answer 1

在 nginx 中，您仍然需要在 url 中使用 http 作为协议，而不是 ws。

proxy_pass http://service_name:3600;

浏览器需要 ws 和 wss 协议，在服务器端，您在下面添加以通过 http

处理 websockets

proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
