Question

我使用的是socket.io V1.2.1＆amp;试图遵循official Socket.io authorization wiki page，但它似乎有点过时（可能是为0.9版编写的），所以在做了一些更改之后，这里是我启动服务器和代码的代码。配置身份验证：

server = http.createServer(app)
io = require('socket.io')(server)
global.io = io
global.liveTopicIo = io.of "/live-topic"
server.listen(3100)
io.set 'authorization', (handshakeData, callback)->
    # doing some authentication logic here 
    # & reading 'currentUser'
    if isAuthenticated
        handshakeData.user = currentUser
        callback null, true
    else
        callback null, false

liveTopicIo.on "connection", (socket) ->
  console.log 'user: ', socket.handshake.user
  console.log 'a user connected'

上一个代码打印以下内容

user：undefined

用户已连接

那么，为什么我无法在handshake数据中添加参数？＆安培;如何修复此问题以添加当前用户？

基于the migration notes from 0.9 to 1.x，授权不再依赖于set函数，而应该是正常的快速中间件，所以它应该是这样的：

liveTopicIo.use (socket, next)->
    # doing some authentication logic here based on the info 
    # from socket.handshake & reading 'currentUser'
    if isAuthenticated
        socket.handshake.user = currentUser
        next()
    else
        next(new Error("Access Denied"))

在验证socket.io时无法添加握手参数
