Nginx 配置文件通常位于 /etc/nginx/nginx.conf,也可以在 /etc/nginx/conf.d/ 下创建新的配置文件,例如 websocket.conf。2. 基本配置结构http { upstream websocket { server localhost:9301; # 定义上游 WebSocket 服务器 } server { listen 9300; # 监听
在Nginx的HTTP处理流程中,关键逻辑位于ngx_http_proxy_module: 1、请求头处理(ngx_http_proxy_handler): if (r->headers_in.upgrade) { ngx_str_set(&h->upgrade, "websocket"); h->headers_in->connection_type = NGX_HTTP_CONNECTION_UPGRADE; } 检测到Upgrade头时设置连接升级标志 Upstream连接建立(ngx...
To turn a connection between a client and server from HTTP/1.1 into WebSocket, the protocol switch mechanism available in HTTP/1.1 is used. There is one subtlety however: since the “Upgrade” is a hop-by-hop header, it is not passed from a client to proxied server. With forward proxying...
i debug websocket service with ip:port, it runs well, this is important. but when i change to nginx for proxy websocket, it happens some connections just closed when request in (i watch the terminal),and the chrome,firefox console return...
WebSocket 是一种基于 TCP 连接的全双工通信的协议,其工作在应用层,建立连接的时候通过复用 Http 握手通道,完成 Http 协议的切换升级,即切换到 WebSocket 协议,协议切换成功后,将不再需要客户端发起请求,服务端就可以直接主动向客户端发送数据,实现双向通信。 和Http 相比,WebSocket有以下优点: WebSocket 是双向通信协...
ENWebSocket 可以减小客户端与服务器端建立连接的次数，减小系统资源开销，只需要一次 HTTP 握手，整个通讯...
在本教程中将说明如何配置Nginx作为Websocket代理服务器,即Nginx的Socket负载均衡。 多Websocket服务器高可用与性能 可以在中间在加入一个代理服务器Nginx,HAProxy,下面是使用Nginx的upstream指令 http{map$http_upgrade$connection_upgrade{defaultupgrade;''close;}upstreamwebsocket{server192.168.100.10:8010;}server{listen80...

2、Nginx配置Websocket代理 可以参考官网文档 WebSocket proxying To turn a connection between a client and server from HTTP/1.1 into WebSocket, the protocol switch mechanism available in HTTP/1.1 is used. There is one subtlety however: since the “Upgrade” is a hop-by-hop header, it is not pa...
被用来升级连接从HTTP到WebSocket的HTTP Upgrade机制使用Upgrade和Connection头部来完成。在反向代理服务器支持WebSocket中,需要面临一些挑战。第一个是WebSocket是一个hop-by-hop协议,所以当代理服务器拦截来至于客服端的一个Upgrade请求时,代理服务器需要发送它自己的Upgrade请求给后端服务器,包括一些合适的头部。同样,因为...
