需要额外加上:
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
例如：
location / {
proxy_pass http://localhost;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
}
实际使用：
http {
upstream wsupstream {
server 127.0.0.1:7397;
}
server {
location ^~/websocket {
location ^~/websocket {
proxy_pass http://wsupstream ;
proxy_connect_timeout 4s;
proxy_read_timeout 3600s;
proxy_send_timeout 12s;
proxy_http_version 1.1;
proxy_redirect off;
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_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
}
}
}
}
亲测可用，有问题可以讨论。
