當nginx裏沒有配置支持webocket時 , 但是已經配置了域名 比如:ws://gofly.sopans.com/ws_visitor
直接js連會返回400的錯誤
需要在nginx location 塊下增加這三個header頭 , 把http連接升級爲websocket連接
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
比如我的開源客服gofly中
server{
listen 80;
server_name gofly.sopans.com;
access_log /var/log/nginx/gofly.sopans.com.access.log main;
client_max_body_size 10M;
location /static {
root /var/www/html/go-fly;
}
location / {
proxy_pass http://127.0.0.1:8081;
proxy_http_version 1.1;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
}
}
