如何获取（Express）的sessionID用于websocket连接 [英] How can I get (Express's) sessionID for a websocket connection

问题描述

我正在Express Express运行的同一个端口上使用WebSockets npm install ws d喜欢从刚刚完成并升级到WebSocket的HTTP连接中提取相关联的sessionID。

  / start express listen 
 server.listen（conf.server.port，conf.server.host）; 
 
 var WebSocketServer = require（'ws'）。server 
，wss = new WebSocketServer（{server：server}）; 
 
 wss.on（'connection'，function（ws）{
 var sessionID = //如何获取这个？
 ws.on（'message'，function消息）{
 console.log（'received：％s'，message）; 
}）; 
 ws.send（'something'）; 
}）; 
  

如何做？

（我目前通过在页面中发送sessionID来解决问题，但这是丑陋的。）

解决方案

1. 解析cookie


2. 获取会话ID



3. 获取会话数据

     var express = require（'express'）; 
    var parseCookie = express.cookieParser（）; 
    var MemoryStore = express.session.MemoryStore; 
    
    var store = new MemoryStore（）; 
    
    app.configure（function（）{
    app.use（express.session（{store：store，secret：'123456'，key：'sid'}））; 
   }）; 
    
    wss.on（'connection'，function（ws）{
    parseCookie（ws.upgradeReq，null，function（err）{
    var sessionID = ws.upgradeReq.cookies ['sid']; 
    store.get（sessionID，function（err，session）{
    // session 
   }）; 
   }）; 
    
    ws.on（'message'，function（message）{
    console.log（'received：％s'，message）; 
   }）; 
    ws.send（'something '）; 
   }）; 
     

I'm using WebSockets npm install ws on the same port as Express is running.

I'd like to pick up the associated 'sessionID' from the HTTP connection which had just been made and upgraded to a WebSocket.

// start express listening
server.listen(conf.server.port, conf.server.host);

var WebSocketServer = require('ws').Server
  , wss = new WebSocketServer({server: server});

wss.on('connection', function(ws) {
    var sessionID = // how do I get this?
    ws.on('message', function(message) {
        console.log('received: %s', message);
    });
    ws.send('something');
});

How can this be done?

(I currently work around the issue by sending the sessionID in the page, but this is ugly.)

解决方案

1. Parse cookie
2. Get session id

3. Get session data

   var express = require('express');
   var parseCookie = express.cookieParser();
   var MemoryStore = express.session.MemoryStore;
   
   var store = new MemoryStore();
   
   app.configure(function() {
       app.use(express.session({ store: store, secret: '123456', key: 'sid' }));
   });
   
   wss.on('connection', function(ws) {
       parseCookie(ws.upgradeReq, null, function(err) {
           var sessionID = ws.upgradeReq.cookies['sid'];
           store.get(sessionID, function(err, session) {
               // session
           });
       }); 
   
       ws.on('message', function(message) {
           console.log('received: %s', message);
       });
       ws.send('something');
   });
