最近在做websocket推送日誌到前臺頁面，部署伺服器是用nginx轉發後無法連線websocket，而且我的nginx還是帶https證書的，下面轉發的配置可以解決這一問題（僅供參考）

#將/xcloud-api請求轉發給http://127.0.0.1:8012處理
        location /xcloud-api {
            proxy_pass http://127.0.0.1:8012/xcloud-api; #這裡的埠記得改成專案對應的哦
            proxy_next_upstream error timeout invalid_header http_500 http_502 http_503;
            proxy_set_header Host $host;
            proxy_http_version 1.1; 
            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;
            proxy_set_header Upgrade $http_upgrade;  
			proxy_set_header Connection "upgrade"; 
            proxy_set_header Origin "";
            proxy_redirect off;
        }
 

主要是這三個配置

proxy_set_header Upgrade $http_upgrade;  
proxy_set_header Connection "upgrade"; 
proxy_set_header Origin "";
