问题描述及解决方法
项目中遇到websocket连接报404的问题，由于项目是有nginx的,首先检查nginx是否开启了websocket穿透，如下面代码展示：
location / {
    proxy_pass http://entertain.sbc.com/xpe-products-sbc-entertain/;
    proxy_cookie_path  /xpe-products-sbc-entertain/ /;
    proxy_http_version 1.1;
    proxy_set_header Host $proxy_host;
    proxy_set_header Real-Host $host; #保留真实域名
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
设置下面两行即可
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
location / {
    proxy_pass http://entertain.sbc.com/xpe-products-sbc-entertain/;
    proxy_cookie_path  /xpe-products-sbc-entertain/ /;
