Socket.io 1.0.5：如何保存会话变量？ [英] Socket.io 1.0.5 : How to save session variables?

问题描述

不幸的是，socket.io开发团队决定弃用函数set（）和get（）。问题是这两个函数允许我们将变量保存到会话中。

Unfortunately socket.io developer team decided to deprecate functions set() and get(). The problem is that these two functions allowed us to save variable into session.

所以我的问题是：socket.io 1.0.5上的下列代码的等价物是什么？

So my question is : What is the equivalent of the folloing code on socket.io 1.0.5 ?

socket.set('mySessionVar', 'myValue');

socket.get('mySessionVar', function (error, mySessionVar) {
    console.log('I have a super variable save in the session : '+mySessionVar);
    socket.emit('mySessionVar', mySessionVar);
});

感谢您的帮助，
Guillaume。

Thank you for your help, Guillaume.

推荐答案

socket.io-handshake 是socket.io 1.x的会话中间件。它建立在快速会话和cookie解析器之上。我知道我们正在谈论socket.io而不是表达，但它仍然适用于socket.io。此示例将使您的会话在redis商店中生效。

socket.io-handshake is session middleware for socket.io 1.x. It is built on top of express-session and cookie-parser. I know we are talking about socket.io and not express, but it still works with socket.io. This example will make your sessions live on a redis store.

var expressSession = require('express-session');
var connectRedis = require('connect-redis')(expressSession);
var cookieParser = require('cookie-parser');
var config = { session: { secret:'secret', key: 'bus.io', store: new connectRedis() } };
var handshake = require('socket.io-handshake');
var io = require('socket.io')(3000);
io.use(handshake(config.session));
io.on('connection', function (socket) {
  socket.handshake.session.data = "whatever data I want";
  socket.handshake.session.save();
});
