我正在尝试让connect / node.js很好地协同工作。 我有以下(在coffeescript中)
connect = require('connect')
io = require('socket.io')
server = connect.createServer(
connect.favicon()
, connect.logger()
, connect.static(__dirname + '/public')
).listen(8000)
socket = io.listen(server)
socket.on 'connection', (socket) ->
socket.send({ hello: 'world' })
但是不断收到以下错误:
TypeError: Cannot call method 'listeners' of undefined
似乎服务器没有及时初始化套接字开始监听..
与:比较:
io = require ("socket.io")
http = require('http')
server = http.createServer()
server.listen(8000)
socket = io.listen(server)
socket.on 'connection', (socket) ->
socket.send({ hello: 'world' })
哪个有用......
答案 0 :(得分:5)
可能是因为.listen()
会返回其他内容。如果你重写这样的代码它应该工作:
connect = require('connect')
io = require('socket.io')
server = connect.createServer(
connect.favicon()
, connect.logger()
, connect.static(__dirname + '/public')
)
server.listen(8000)
socket = io.listen(server)
socket.on 'connection', (socket) ->
socket.send({ hello: 'world' })
