无法连接到socket.io两次

我写了一个socket.io服务器，我用mocha来testing它。 但是我无法第二次连接到服务器。

这是我的代码，它是由咖啡脚本写的。

服务器：

 server = require('http').Server() io = require('socket.io').listen(server) io.on 'connection', (socket) -> console.log socket.id server.listen(3000) 

testing：

 chai = require 'chai' io = require 'socket.io-client' should = chai.should() describe 'Socket', ()-> url = 'http://0.0.0.0:3000' it 'should be connected', (done) -> client = io.connect(url) client.on 'connect', (data) -> console.log(data) client.socket.connected.should.equal(true) client.disconnect() done() describe 'User', ()-> url = 'http://0.0.0.0:3000' it 'should be connected', (done) -> client = io.connect(url) client.on 'connect', (data) -> console.log(data) client.socket.connected.should.equal(true) client.disconnect() done() 

服务器输出：

  info - socket.io started debug - client authorized info - handshake authorized b_2h4dCr-YfD-7-Iw9Hl debug - setting request GET /socket.io/1/websocket/b_2h4dCr-YfD-7-Iw9Hl debug - set heartbeat interval for client b_2h4dCr-YfD-7-Iw9Hl debug - client authorized for debug - websocket writing 1:: b_2h4dCr-YfD-7-Iw9Hl debug - got disconnection packet info - transport end by forced client disconnection debug - websocket writing 0:: info - transport end (booted) debug - set close timeout for client b_2h4dCr-YfD-7-Iw9Hl debug - cleared close timeout for client b_2h4dCr-YfD-7-Iw9Hl debug - cleared heartbeat interval for client b_2h4dCr-YfD-7-Iw9Hl debug - discarding transport 

摩卡输出：

当你想创build新的会话 – 为.connect方法设置“强制新连接”选项

 io.connect(socketAddress,{'force new connection': true});
