当nginx里没有配置支持webocket时 , 但是已经配置了域名 比如:ws://gofly.sopans.com/ws_visitor
直接js连会返回400的错误
需要在nginx location 块下增加这三个header头 , 把http连接升级为websocket连接
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
比如我的开源客服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";
}
}
