在nodeJS中获取SESSIONID [英] Get SESSIONID in nodeJS

问题描述

现在，在玩了几个小时的nodejs和socket.io之后，我遇到了另外两个问题-一个问题是，我需要在node.js内获取sessionID，然后使用app.get('/' ...退出-因为连接socket.io时似乎不会触发该事件，它只会触发.on('connection', function( ...

Now, after some hours of playing around with nodejs and socket.io, I'm getting a couple more problems - one being, that I need to get the sessionID inside node.js, whitout using app.get('/' ... - since that event doesnt seem to fire when socket.io connects, it only fires .on('connection', function( ...

var express = require('express')()
express.set('port', process.env.PORT || 8080)

var server = require('http').createServer(express)
var socket = require('socket.io').listen(server)

server.listen(express.get('port'))

// this event is fired, get('/', ... isnt!
server.on('connection', function(stream) {
    // ??
} )

Session最初是由PHP应用程序创建的，当用户登录时.Session数据存储在数据库中，我需要访问该数据的键是SESSION ID.最简单的方法是什么?如前所述，我找到了几个使用app.get('/' ...的示例，但我根本无法触发该事件.

The Session is initially created by the PHP application, as the user logs in. Session data is stored in the database, and the key I need to access that data is the SESSION ID. What's the easiest way to get to it? Like mentioned, I found a couple examples that used app.get('/' ... but I couldnt get that event to fire at all.

谢谢.

推荐答案

如果会话数据被存储为cookie(最有可能)，那么您应该能够在套接字握手期间重新解析该数据.我在此答案上发布了该代码，但也在此处复制了该代码:

If the session data is being stored as a cookie (most likely), then you should be able to re-parse that data during the socket handshake. I posted code for that on this answer, but copied the code here as well:

io.configure(function () {
  io.set('authorization', function (handshakeData, callback) {

    var cookie = handshakeData.headers.cookie;

    // parse the cookie to get user data...

    // second argument to the callback decides whether to authorize the client
    callback(null, true);
  });
});

如果会话数据正在URL中传播，则可以从handshakeData.url或handshakeData.query收集此信息.您可能必须要做自己的实验.

If the session data is being propagated in the URL, then you may be able to gather this information from handshakeData.url or handshakeData.query. You'll probably have to do your own experimentation.
