我正在使用 nginx 1.4.1，我正在尝试将其配置为与 socket.io websockets 一起使用。我认为我做对了，因为我看到“握手授权”，但几秒钟后 socket.io 开始使用 xhr-polling、jsonp-polling 并且无法工作。

我的 node.js express 应用在 localhost:3002 上运行。我使用 nginx 反向代理到这个应用程序。Socket.io 也在同一个端口上监听。

我试图遵循 SO 和其他地方的许多指南，但我无法让它发挥作用。需要一些专家的帮助。我也在这里通过错误登录放置，不确定它是否会有所帮助。

nginx.conf：

upstream instaneous {
                server 127.0.0.1:3002;
}


server {
                listen 80;
                server_name instaneous.pin.gs;
                access_log logs/instaneous.access.log;
                error_log logs/instaneous.error.log;

                location / {
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_set_header X-NginX-Proxy true;

        proxy_pass http://instaneous;
        proxy_redirect off;

        # enables WS support
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
                }

        }
