让pomelo可以获取到反向代理websockets的真实用户IP

/node_modules/pomelo/lib/connectors/hybridsocket.js

找到

var Socket = function(id, socket) {

给remoteAddress对象新增加个realIp属性，从ws对象的握手请求头里找到反向代理发送的用户真实IP头

//ws模式，过滤IPV4前面的无用IPV6头
var ip = socket._socket.remoteAddress;
var realIp = socket.upgradeReq.headers['x-forwarded-for'] || socket.upgradeReq.headers['x-real-ip'] || socket.upgradeReq.headers['X-Client-Address'] || ip;
this.remoteAddress = {
ip: ip.replace(/::ffff:/, ''),
port: socket._socket.remotePort,
realIp: realIp.replace(/::ffff:/, '')
};

/node_modules/pomelo/lib/common/service

再修改pomelo的sessionServer 类的 getClientAddressBySessionId 方法
