nginx配置如下:

map $http_upgrade $connection_upgrade {
            default upgrade;
            ''      close;
    }
upstream websocket {
            #ip_hash;
            server 10.50.127.59:3000;
            server 10.50.127.60:3000;
    }


server {
    listen       80;
    server_name localhost;

    location / {
        proxy_pass http://websocket;
        
        
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection  $connection_upgrade;
    }
}

并且即使部署成功后,建立连接非常慢. 用chrom测试,发现连接协议为jsonpolling. 求解,谢谢!

根据实际测试得出.根据官网的配置是确实可行的. 出现这样的原因,是因为服务外网映射的问题和nodejs和socket.io无关. 内网测试正常,外网映射NAT等问题.
