问题记录:本地socket测试无误后部署发现 WebSocket connection to "xxx/xxx" failed
解决方案:
在nginx.conf的http模块添加如下内容
map $http_upgrade $connection_upgrade { default upgrade; '' close; }
其次在反向配置中Nginx Location下添加如下代码
proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade";
从版本1.3.13开始,nginx实现特殊的操作模式,如果代理服务器返回带有代码101(交换协议)的响应,则允许在客户端和代理服务器之间建立隧道,
并且客户端要求通过请求中的“升级”标头:Nginx官网
