Nginx配置websocket的反向代理

由于一般会有跨域问题，就直接把跨域也一并配置了。Nginx的跨域配置详情可以参考我之前的文章：Nginx配置跨域请求

websocket的反向代理配置：

直接贴代码：

server {    listen 9000; # 监听9000端口    server_name   websocket_server;    # 允许跨域    add_header Access-Control-Allow-Origin *;    add_header Access-Control-Allow-Methods 'GET, POST, OPTIONS';    add_header Access-Control-Allow-Headers 'DNT,X-Mx-ReqToken,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Authorization';    if ($request_method = 'OPTIONS') {        return 204;    }    location / {        #添加wensocket代理        proxy_pass http://127.0.0.1:9093;  # websocket服务器。不用管 ws://        proxy_http_version 1.1;        proxy_set_header Upgrade $http_upgrade;        proxy_set_header Connection "upgrade";    }}
